3. POSITIONING THE UNIT 

CAUTION 

IF USING A COUNTER TO POSITION THE UNIT, BE SURE THAT THE COUNTER WILL 

SUPPORT THE WEIGHT OF THE MACHINE [APPROXIMATELY 360 POUNDS (163.3 KG), 

EMPTY WEIGHT]. 

CHECK POSITIONING WITH THE MOUNTING DIAGRAM (SEE PAGE 34) BEFORE LIFTING 

MACHINE TO COUNTER. (REFER TO SECTION 14.1 OF THIS MANUAL FOR HOLE 

LOCATIONS.) 

INSURE THAT THERE IS ADEQUATE AIR SPACE ABOVE [MINIMUM OF TWELVE (12) INCHES 

(30.48 CM)] AND BEHIND [MINIMUM OF TWO (2) INCHES (5.08 CM)] THE UNIT FOR 

VENTILATION. 

3.1 COMMON METHODS OF POSITIONING 

A. The two most common methods of positioning the unit are: 

1. Flush mounting - The most common method used; positions the unit directly onto the 

countertop surface. 

2. Roll around base cabinet - The unit rests on top of the optional roll around cabinet. This 

method allows the unit to be rolled out of position for cleaning. 

B. Use the following guidelines to position and secure a flush mount unit to the countertop. 

1. There are four (4) threaded mounting holes (3/8-16 UNC) in the base of the frame, should 

the unit need to be permanently mounted (refer to Section 14.1 of this manual for hole 

locations). Prepare the surface for mounting, but do not attach the unit at this time (see 

Figure 7).

Figure 7 Figure 8 

WARNING 

THIS UNIT MUST BE PROPERLY ELECTRICALLY GROUNDED TO AVOID POSSIBLE FATAL 

ELECTRICAL SHOCK OR SERIOUS INJURY TO THE OPERATOR. THE POWER CORD IS 

PROVIDED WITH A THREE PRONG GROUNDED PLUG. IF A THREE-HOLE GROUNDED 

ELECTRICAL OUTLET IS NOT AVAILABLE, USE AN APPROVED METHOD TO GROUND THE UNIT. 

4.1 Use the following guidelines to connect electrical power to the machine for 50-60 Hz service. 

A. The machine requires 220 volts alternating current. If line voltage is below 215VAC or above 

245VAC, a 10% buck and boost transformer must be used. Operation below 215VAC or above 

245VAC may damage the unit and cause inconsistent performance. This also voids all 

warranties. 

B. The unit is a single phase machine. If connected to a “delta” three phase electrical system, the 

machine must not be connected to the high leg as one of the two (2) power legs. This will cause 

the machine to malfunction. If a delta system is used, check each leg to ground to insure the 

“low legs” are used. 

CAUTION 

THIS UNIT WILL NOT WORK PROPERLY IF THERE IS MORE THAN A 10V VOLTAGE DROP IN 

THE POWER SUPPLY LINE BETWEEN THE POWER SOURCE AND THE MACHINE. A DROP 

OF MORE THAN 10V INDICATES UNDERSIZED WIRING OR EXCESSIVELY LONG RUNS. 

C. The unit must be installed on a “single branch” circuit (on a circuit by itself), protected by a 

30 Amp service and a 30 Amp fuse for both 50 and 60 Hz. 

WARNING 

ALWAYS DISCONNECT ELECTRICAL POWER TO THE UNIT TO PREVENT PERSONAL 

INJURY BEFORE ATTEMPTING ANY INTERNAL MAINTENANCE. ONLY QUALIFIED 

PERSONNEL SHOULD SERVICE INTERNAL COMPONENTS OR ELECTRICAL WIRING. 

4

CAUTION 

IF A DELTA THREE PHASE POWER SOURCE IS USED, USE THE TWO LOW VOLTAGE LEGS. 

DO NOT USE THE SINGLE HIGH LEG. TO DO SO WILL CAUSE SOFTWARE TO 

MALFUNCTION. 

D. It is recommended that a 3 conductor, 30 Amp, “L” receptacle be used (see Figure 9). Using a 

voltmeter, check voltage across both “hot legs” (240VAC) and between ground and each “hot 

leg” (120VAC). Check for continuity on the plug across both “hot legs” and no continuity 

between each “hot leg” and ground (see Figure 10). 

WARNING 

DO NOT CONNECT POWER TO THE MACHINE AT THIS TIME. 

E. If using an existing outlet, check it for proper wiring prior to installation. If readings are not as 

shown in Figure 9, the receptacle is not wired correctly and damage to the machine will 

occur if plugged in. Do NOT connect power to machine at this time.

5.1 BAG-IN-BOX (BIB) INSTALLATION 

Use the following steps for connecting water, CO2, and syrup. The unit can be connected using one 

of the following methods: 

A. Water Connections 

IMPORTANT 

A WATER PUMP AND WATER REGULATOR ARE INSTALLED IN THE BASE OF THE 

MACHINE. A WATER FILTER SHOULD BE INSTALLED IN THE WATER LINE BEFORE 

BEING CONNECTED TO THE MACHINE. THE UNIT REQUIRES A MINIMUM OF 30 PSIG 

(206.8 KPA) WATER PRESSURE. FLUSH THE FILTER WITH SEVERAL GALLONS 

(12-15 LITERS) OF WATER PRIOR TO USE TO INSURE BLACK CARBON “FINES” ARE NOT 

FED INTO THE FREEZING CHAMBER. 

1. Using 3/8 inch tubing, connect the unit to a potable water supply. Bulkhead fittings are 

located in the rear of the machine. The label adjacent to the bulkhead denotes proper hose 

connections (see Figure 13). Install a shutoff valve in the water line as close to the unit as 

practical and convenient. 

NOTE 

Water pipe connections and fixtures directly connected to a potable water supply shall be 

sized, installed, and maintained according to Federal, State and local laws. 

2. Clear the line by running a minimum of two (2) gallons (7.57 liters) of water through the line 

before attaching the line to the bulkhead fitting labeled “WATER IN”. 

NOTE 

Do not turn water on at this time. 

3. Fabricate a 3/8 inch supply line to the “WATER IN” connector on the rear of the unit. 

5

B. CO2 Connections 

WARNING 

CO2 DISPLACES OXYGEN. STRICT ATTENTION MUST BE OBSERVED IN THE 

PREVENTION OF CO2 (CARBON DIOXIDE) GAS LEAKS IN THE ENTIRE CO2 AND SOFT 

DRINK SYSTEM. IF A CO2 GAS LEAK IS SUSPECTED, IMMEDIATELY VENTILATE THE 

CONTAMINATED AREA BEFORE ATTEMPTING TO REPAIR THE LEAK. 

PERSONNEL EXPOSED TO HIGH CONCENTRATIONS OF CO2 GAS WILL EXPERIENCE 

TREMORS WHICH ARE FOLLOWED RAPIDLY BY LOSS OF CONSCIOUSNESS AND 

SUFFOCATION. 

CAUTION 

TO AVOID PERSONAL INJURY AND/OR PROPERTY DAMAGE, ALWAYS SECURE CO2 

CYLINDERS IN AN UPRIGHT POSITION WITH A SAFETY CHAIN TO PREVENT CYLINDERS 

FROM FALLING OVER. SHOULD THE VALVE BECOME ACCIDENTALLY DAMAGED OR 

BROKEN OFF, A CO2 CYLINDER CAN CAUSE SERIOUS PERSONAL INJURY. 

1. The CO2 supply may be attached to either an independent tank and regulator, or to a branch 

line of an existing bulk CO2 system. Install a shutoff valve and a supply regulator in the line 

from any existing branch. Fabricate a 1/4 inch supply line to reach the “CO2 IN” connector 

on the rear of the unit. 

2. Connect the CO2 supply line to the CO2 connector on the dispenser. 

3. Splice a 1/4 inch barb cross into the CO2 supply line and run lines to the syrup pumps. 

CAUTION 

CHECK ALL SUPPLY LINES TO INSURE THAT THEY ARE CONNECTED TO THE CORRECT 

FITTINGS. IF LINES ARE NOT CONNECTED PROPERLY, COMPONENTS WILL BE 

DAMAGED. 

4. Check all CO2 connections for tightness. 

NOTE 

Do NOT turn on the CO2 at this time. 

C. Syrup Connections 

1. Fabricate two (2) 1/4 inch supply lines to reach from the “SYRUP #1 BIB Pump” and the 

“SYRUP #2 BIB Pump” to the “SYRUP #1 LEFT” and “SYRUP #2 RIGHT” connectors on 

the rear of the unit. 

NOTE 

If the syrup inlet line exceeds 25 feet (7.62 meters) in length, 

use a 3/8 inch supply line. 

2. Installations requiring long runs of tubing [30 - 50 feet 

(9.14 - 15.24 meters)] may encounter problems. The 

machine’s sensors may indicate that the machine is out of 

syrup or water. Consider the following solutions: 

a. Increase the tubing size from 1/4 inch diameter to 

3/8 inch diameter. 

b. Install booster pumps in the supply lines. 

c. Increase CO2 regulator pressure to 120 PSIG 

(827.3 KPa) [from the normal 105 PSIG (723.9 KPa)] on 

the primary regulator at the CO2 tank or supply. 

3. Connect all lines and check all fittings for tightness.

5.2 FIVE GALLON (FIGAL) REFILLABLE TANK INSTALLATION 

This installation involves the use of refillable five gallon (figal) tank CO2 and syrup supply units. The 

figures that accompany these steps illustrate the proper routing of hoses for this installation. 

A. Water Connections 

IMPORTANT 

A WATER PUMP AND WATER REGULATOR ARE INSTALLED IN THE BASE OF THE 

MACHINE. A WATER FILTER SHOULD BE INSTALLED IN THE WATER LINE BEFORE 

BEING CONNECTED TO THE MACHINE. THE UNIT REQUIRES A MINIMUM OF 30 PSIG 

(206.8 KPA) WATER PRESSURE. FLUSH THE FILTER WITH SEVERAL GALLONS 

(12-15 LITERS) OF WATER PRIOR TO USE TO INSURE BLACK CARBON “FINES” ARE NOT 

FED INTO THE FREEZING CHAMBER. 

1. Using 3/8 inch tubing, connect the unit to a potable water supply. Bulkhead fittings are 

located in the rear of the machine. The label adjacent to the bulkhead denotes proper hose 

connections (see Figure 13). Install a shutoff valve in the water line as close to the unit as 

practical and convenient. 

NOTE 

Water pipe connections and fixtures directly connected to a potable water supply shall be 

sized, installed, and maintained according to Federal, State and local laws. 

2. Clear the line by running a minimum of two (2) gallons (7.57 liters) of water through the line 

before attaching the line to the bulkhead fitting labeled “WATER IN”. 

NOTE 

Do not turn water on at this time. 

3. Fabricate a 3/8 inch supply line to the “WATER IN” connector on the rear of the unit. 

B. CO2 Connections 

WARNING 

CO2 DISPLACES OXYGEN. STRICT ATTENTION MUST BE OBSERVED IN THE 

PREVENTION OF CO2 (CARBON DIOXIDE) GAS LEAKS IN THE ENTIRE CO2 AND SOFT 

DRINK SYSTEM. IF A CO2 GAS LEAK IS DETECTED OR SUSPECTED, IMMEDIATELY 

VENTILATE THE CONTAMINATED AREA BEFORE ATTEMPTING TO REPAIR THE LEAK. 

PERSONNEL EXPOSED TO HIGH CONCENTRATIONS OF CO2 GAS WILL EXPERIENCE 

TREMORS WHICH ARE FOLLOWED RAPIDLY BY LOSS OF CONSCIOUSNESS AND 

SUFFOCATION. 

CAUTION 

TO AVOID PERSONAL INJURY AND/OR PROPERTY DAMAGE, ALWAYS SECURE CO2 

CYLINDERS IN AN UPRIGHT POSITION WITH A SAFETY CHAIN TO PREVENT CYLINDERS 

FROM FALLING OVER. SHOULD THE VALVE BECOME ACCIDENTALLY DAMAGED OR 

BROKEN OFF, A CO2 CYLINDER CAN CAUSE SERIOUS PERSONAL INJURY. 

1. The CO2 supply may be attached to either an independent tank and regulator, or to a branch 

line of an existing bulk CO2 system. Install a shutoff valve and a supply regulator in the line 

from any existing branch. 

2. Connect the CO2 supply line to the CO2 connector on the dispenser. 

CAUTION 


FITTINGS. COMPONENTS WILL BE DAMAGED IF LINES ARE NOT CONNECTED 

PROPERLY. 

3. Splice a 1/4 inch barb cross into the CO2 supply line and run lines to the syrup tank. 

4. Check all CO2 connections for tightness. 

NOTE 

Do NOT turn on the CO2 at this time. 

7

C. Syrup Connections (see Figure 12) 

1. Fabricate two (2) 1/4 inch supply lines to reach from “SYRUP SRV #1” and “SYRUP SRV 

#2” to the “SYRUP #1 LEFT” and “SYRUP #2 RIGHT” connectors on the rear of the unit. 

Syrup pumps are not required with the five gallon (figal) refillable tanks. 

CAUTION 

SYRUP RESTART VALVES (SRV) MUST BE USED WITH SYRUP TANKS. WARRANTIES 

WILL BE VOID IF THE SRVs ARE NOT INSTALLED. 

2. The “OUT OF” devices in the machine will not function properly without the use of Syrup 

Restart Valves. If the “OUT OF” devices do not function, the machine will then supply only 

water and “freeze up”. 

3. To operate the SRV, press the restart button after each tank is changed. Refill will not start 

until the machine refreezes product, and the red light beside each chamber goes out. 

NOTE 

When replacing a figal, insure that the SYRUP SRV line to the dispenser is attached to the 

figal before the CO2 line is attached to the figal. This will allow the SRV to work properly. 

4. Installations requiring long runs of tubing 

[30-50 feet (9.14-15.24 meters)] may 

encounter problems. The machine’s sensors 

CO2 

may indicate that the machine is out of syrup 

or water. Consider the following solutions: 

a. Increase the tubing size from 1/4 inch 

diameter to 3/8 inch diameter. 

b. Install booster pumps in the supply lines. 

c. Increase CO2 regulator pressure to 

120 PSIG (827.3 KPa) [from the normal 

105 PSIG (723.9 KPa)] on the primary 

regulator at the CO2 tank or supply. 

5. Connect all lines and check all fittings for tightness. 

6. STARTING THE UNIT 

Syrup Restart Valve Hook Up

8

and adjust the primary regulator mounted on the CO2 supply tank to 70-75 PSIG (482.6 KPa to 

517.1 KPa) (see Figure 13 or Figure 15). Recheck all CO2 line connections for leaks. 

NOTE 

The primary CO2 supply regulator must be set at 70-75 PSIG (482.6 KPa to 517.1 KPa) to 

insure 70-75 PSIG (482.6 KPa to 517.1 KPa) CO2 supply to the machine. 

G. Check all syrup supply connections at the rear of the machine for leaks. 

H. Plug unit IN to the electrical power. 

I. Remove splash plate and electric box cover. Check for illumination of the graphics display. 

J. Check for the display of information on the LCD control panel (this will read “COPYRIGHT”). 

Recheck voltage between L1, L2 and, between L1 and ground, and between L2 and ground for 

proper voltage at contactor. 

K. The voltage offset must be set (see Sections 7.3 and 7.4). 

L. Insure that the CO2 secondary regulator (located inside the machine) is adjusted to read 

30-32 PSIG (206.8 to 220.8 KPa). 

NOTE 

This step must be verified. See Common Readouts, “Regulated CO2” (see Section 7.4). 

M. Access the MANUAL ON/OFF MODE in the service menu through the control panel (see 

Section 7.1.C, Operating Electronic Controls, for assistance on accessing menus).

MODEL 500 FCB BRIXING PROCEDURES 

TO SET BRIX 

Step 1 With “FILL” OFF, hold a container under the sample tube and depress sample valve fully until 

a good water and syrup mixture is obtained (see Note 1). This sample should be discarded. 

Step 2 To take brix, place a sixteen (16) ounce (0.473 l) cup under sample tube and press down fully 

on sample valve until 9 - 12 ounces (0.266 - 0.355 l) have been dispensed into cup (see Notes 

1, 2, 3, 4). 

Step 3 Measure brix with a refractometer. If brix needs to be adjusted, see Note 5. 

Step 4 Repeat Steps 2 and 3 above three (3) times to verify accurate brix level. 

TO FILL CHAMBER AND VERIFY BRIX 

Step 5 Access the “MANUAL ON/OFF MENU” in the service menu through the control panel. 

Step 6 From the “MANUAL ON/OFF MENU” in the service menu, fill the chamber with CO2 to the 

pressure shown on the CO2 regulator. 

Step 7 Press the “FILL” button to begin filling the chamber, while slowly venting off CO2 through the 

relief valve located on the front of the chamber. Fill one chamber at a time. 

Step 8 When the chamber is half full, turn beater ON. Draw a sample, check brix level, and then turn 

beater OFF. 

Step 9 Complete the chamber fill and venting process until the chamber is 90% full. Repeat this 

procedure for the other chamber. When both chambers are 90% full, press the “OFF” button. 

NOTES 

Note 1 When depressing sample valve, make sure sample valve travels until it reaches its stop. 

Note 2 A minimum sample of 9 to 12 ounces (0.266 - 0.355 liter) must be dispensed to measure 

brix accurately. 

Note 3 Always discard first samples taken, even after adjusting brix. 

Note 4 Brix readings are affected by temperature. Samples taken from the chamber should be 

the same temperature as a sample taken from the sample valve. 

Note 5 To increase the brix level, turn the syrup flow controller screw clockwise. To decrease 

the brix level, turn the syrup flow controller screw counter-clockwise. 

R. Press the “DEFROST” and “RUN” buttons on the control panel to allow the machine to 

automatically baseline. The machine will remain in DEFROST for a minimum of 45 seconds and 

then the machine will baseline and readjust beater percent to 1000. 

S. After the defrost cycle is completed, the unit will start automatic freeze cycles. 

T. The drink products must be given time to stabilize prior to making adjustments. After an 

initial freeze down [approximately ten (10) to twelve (12) minutes], dispense product and check 

for quality. To make adjustments to product quality, start with verifying proper Operating 

Pressure (See Section 9 to change quality of the drink). 

NOTE 

On an initial freeze down, products must be given adequate time to absorb CO2. Until CO2 is 

properly and adequately absorbed, drinks could be too “wet” or too “heavy” - conversely, if 

adjustments to drink quality are made too late, the drink could become too “dry” or too “light”. 

U. Check CO2, Water, and Syrup lines for leaks. 

V. Seal the unit to the countertop (if applicable) and replace all panels (see Section 3.1 for details 

on positioning and sealing the unit to the counter).

CRITICAL REGULATOR AND FLOW CONTROL SETTINGS 

CO2 TANK REGULATOR The CO2 Primary Regulator MUST BE SET TO 70-75 PSIG 

(Primary Regulator) 

(482.6 TO 517.5 KPa). 

CO2 PROCESS REGULATOR The CO2 Secondary Regulator SHOULD BE SET AT 30-32 PSI 

(Secondary Regulator) (206.8 TO 220.8 KPa) STATIC PRESSURE. 

The CO2 Secondary Regulator is on the header assembly which is 

behind the access panel. This regulator is a “non-vent” regulator. 

This means that if you lower the regulator setting, you will need to 

dispense drinks until cylinder begins to refill before the new setting 

will register on the display. Lowering this setting will produce a 

“heavier” drink. A lower setting is often preferred for “COLA” drinks. 

FLOW CONTROLLERS 

BRIX MUST BE SET BETWEEN 13.5 - 15. Flow controllers are on 

the header assembly. A sample may be taken by pushing down on 

the sample valve while”FILL” is in the “FULL OFF” position.

7. OPERATION OF THE DISPENSER 

7.1 OPERATING ELECTRONIC CONTROLS 

A. The electronic machine controls are designed to provide a logical sequence of operation with a 

minimum of written instruction. The ease of operation is similar to operating a digital watch. 

System operating parameters are selected and set from a menu. 

B. Left and Right Operator Push Buttons (see Figure 16) 

1. The control panel is arranged with two sets of operator control buttons. 

2. Each side has five (5) active buttons. These are labeled FILL, BEATER, RUN, DEF, and 

OFF. After initial setup by the service technician, the operator will only need to access the 

RUN, OFF, and DEF buttons. 

3. Each button operates a double acting switch. Pressing the button once activates the 

process. Pressing the button a second time deactivates the process. Take care not to 

double press the buttons when first activating a process. Press the process button you 

wish to activate, release and wait for the response. 

RUN 

The RUN button activates all the machine’s systems. The beater motor must 

run for two (2) minutes before the machine will freeze or defrost. Refrigeration 

is turned on with a delay in the compressor start before each “refreeze cycle”. 

This delay eliminates the possibility of ”short cycle” damage. The delay time is 

30 seconds. This only occurs if the compressor has not been off for 

30 seconds. 

OFF 

The OFF button turns off all the machine’s systems. 

12

BEATER 

DEF 

FILL 

The BEATER button activates the beaters inside the freezing chambers. The 

beaters can be activated to mix the slurry. The beaters start automatically when 

the RUN button is pressed. The two (2) minute delay that is programmed into 

the initial compressor start is also tied to the beater motors. If the beaters are 

activated two (2) minutes prior to pressing the RUN button, the compressor will 

start immediately upon pressing the RUN button. 

The DEF button allows for a manual defrost of the freezing chamber. The 

machine has an automatic defrost cycle programmed into the operating system. 

It is not necessary to defrost manually but this button provides the option to do 

so. The beater motors must be running two (2) minutes prior to the initial 

defrost, or the defrost will be delayed for two (2) minutes prior to the start of 

defrost. 

The FILL button activates the valves that allow product to flow into the freezing 

chambers prior to startup. Each chamber should be filled to 90% of chamber 

capacity (level with the vent valves). 

C. Common Controls and Displays 

1. The four control buttons, located below the LCD display, allow access to the computer 

controls and set levels for the machine. 

CANCEL 

The CANCEL button cancels any mode currently being monitored or changed 

and steps the operator up one (1) level in the menu. 

BACK 

The BACK button steps the operator backwards through the menu display. This 

button also allows the operator to decrease or lower values. 

FWD 

The FWD button steps the operator forward through the menu display. This 

button also allows the operator to increase or raise values. 

SELECT 

The SELECT button confirms and enters any change or mode being monitored 

and steps the operator down one (1) level in the menu. 

2. The LCD display screen in the center of the control panel allows the operator to monitor the 

status of each chamber (see Figure 17). The screen is divided into three (3) sections. The 

upper left and right portions of the screen display the current status of each chamber. The 

lower half of the screen displays the mode that is being changed or monitored.

D. Access to the Computer and Control Panel (See Figure 18) 

1. Access to the control panel is separated into two levels. These levels have been 

established to make certain information available to the operators and other information 

available to service personnel. 

Level One This level is used for the machine operator at the store level. The store 

operator will only have access to this level of information. Access to any 

other level may cause damage to the machine if information is changed 

improperly. 

Level Two Level Two has been established for an authorized service technician. This 

level provides access to all setup values that will optimize the operation of the 

machine. Incorrect settings at this level could prevent the machine from 

operating or cause damage to the unit. Included in this level are various 

accumulated totals and diagnostic tools that help the technician evaluate 

problems. 

NOTE 

To access Level Two, press the FWD button on the control panel until 

SERVICE MENU displays. Press the unmarked button on the right side of 

the panel. The service menu has been accessed when MACHINE 

SETTINGS displays. Press FWD to access other options. 

E. How to Access and Change Values 

The same procedure for changing values applies to all access levels. The following steps allow 

the parameters of the control system to be monitored and changed. 

1. The current mode of each chamber is displayed in the lower half of the LCD. Press the 

FWD button to step to the next mode. Continue pressing the FWD or BACK button until the 

desired mode is displayed. 

2. To make changes to the displayed mode, press the SELECT button. When a value in the 

lower half of the display begins to flash, this indicates that the value can be changed. 

3. To change the value, press the FWD button to increase the value or the BACK button to 

decrease the value. Any on/off functions can be changed by pressing the SELECT button. 

4. Once the desired value is displayed, press the SELECT button to enter the value into the 

computer. Pressing the SELECT button will stop the display from flashing. When the value 

stops flashing, it has been changed. 

NOTE: 

When entering TIME, WAKE, or SLEEP functions, both the hours and minutes must be 

selected before the computer will accept the change.

8. CLEANING AND SANITIZING THE UNIT 

8.1 GENERAL INFORMATION 

NOTE 

The following cleaning and sanitizing procedures pertain to the Lancer FBD equipment identified by 

this manual. If other equipment is being cleaned, follow the guidelines established for that 

equipment. 

A. Lancer equipment (new or reconditioned) is shipped from the factory, cleaned and sanitized in 

accordance with NSF guidelines. After installation is complete, the operator of the equipment 

must provide continuous maintenance as required by this manual and/or state and local health 

department guidelines to ensure proper operation and sanitation requirements are maintained. 

B. Cleaning and sanitizing should be accomplished only by trained personnel. Sanitary gloves are 

to be used during cleaning and sanitizing operations. Applicable safety precautions must be 

observed. Instruction warnings on the product being used must be followed. 

C. Water lines are not to be disconnected during the cleaning and sanitizing of syrup lines to avoid 

contamination. 

D. Do NOT use strong bleaches or detergents. They tend to discolor and corrode various 

materials. 

E. Do NOT use metal scrapers, sharp objects, steel wool, scouring pads, abrasives, solvents, etc., 

on the dispenser. 

F. Do NOT use hot water above 140 o F (60 o C). This may damage certain materials. 

8.2 REQUIRED CLEANING EQUIPMENT 

A. A mild soap solution (for example, Ivory Liquid, Calgon, etc.) mixed with clean, potable water at 

a temperature of 90 to 110 degrees Fahrenheit should be used to clean equipment. Any 

equivalent mild soap solution may be used as long as it provides a caustic based, 

non-perfumed, easily rinsed mixture containing at least two (2) percent sodium hydroxide 

(NaOH). Rinsing must be thorough and use clean, potable water which is also at a temperature 

of 90 o to 110 o F. 

B. Sanitizing solutions should be prepared in accordance with the manufacturer’s written 

recommendations and safety guidelines. Any sanitizing solution may be used as long as it is 

prepared in accordance with the manufacturer’s written recommendations and safety guidelines, 

and provides 200 parts per million (PPM) available chlorine. Sanitizing solution is to be purged 

from line(s) and equipment by flushing with product only until there is no after taste. Do not rinse 

with water. 

NOTE 

Please note that a fresh water rinse cannot follow sanitization of equipment. Purge only with the 

end use product until there is no after taste in the product. This is an NSF requirement. 

8.3 DAILY CLEANING OF THE UNIT 

CAUTION 

DO NOT USE ABRASIVE TYPE CLEANERS. 

A. On a daily basis, or more often if necessary, wash all exterior surfaces of unit with a mild soap 

solution. Rinse with clean water. Wipe dry with a clean soft cloth. 

B. Remove and wash drip tray in mild soap solution. Rinse with clean water. Reinstall drip tray on 

unit. 

19

8.4 SANITIZING THE SYRUP SYSTEMS 

WARNING 

IF POWDER TYPE SANITIZER IS USED, IT MUST BE COMPLETELY DISSOLVED WITH 

WATER PRIOR TO ADDING TO THE SYRUP SYSTEM. THE USE OF HOT WATER WILL HELP 

DISSOLVE POWDER TYPE SANITIZERS. 

The unit should be sanitized every 90 days. Follow sanitizer manufacturer’s recommendation in 

preparing sanitizing solution. 

A. Disconnect BIB connectors from syrup boxes. Screw the clean BIB "Sanitizing Adapter" onto 

the BIB connectors. 

NOTE: 

If adapter is not available, cut the BIB fitting out of empty bag to use as adapter. 

B. Prepare concentration of sanitizing solution. 

NOTE: 

Follow manufacturer's mixing instructions, but make solution slightly stronger than normal due 

to water dilution in machine. 

C. Press the "FILL" button, quickly place the BIB "Sanitizing Adapter" into container of sanitizing 

solution. The solution will begin to fill the syrup system and cylinder with sanitizing solution. 

D. Pull faceplate relief valve to relieve pressure, which allows filling of cylinder. Fill until sanitizing 

solution comes out of relief valve port. 

E. Press "OFF", than "BEATER” button to start the beater motor. 

NOTE: 

Allow sanitizing solution to remain in the chamber for no more than 15 minutes. 

F. Remove BIB "Sanitizing Adapter" from sanitizing solution, then remove adapters. Reconnect 

the BIB connectors to syrup boxes. 

G. Place empty container under the Brix sample valve. Slowly depress valve and hold until syrup 

is again present, then release valve. 

H. Activate "CO2 Sol L" and "CO2 Sol R" in Manual On/Off" menu. Hold appropriate container 

under dispensing valve and dispense product from chamber. As product level drops, partially 

close valve to avoid sputtering. Evacuate cylinders, and then deactivate "CO2 Sol L" and "CO2 

Sol R". 

I. Press "Fill" button, allowing the chamber to fill until the solenoid stops. Pull ring on faceplate 

relief valve to vent cylinder. Continue until cylinder is one half (1/2) full, then press "OFF" 

button. 

J. Repeat steps "7-H" and "7-I" several times. Taste the beverage between fillings to verify there 

is no off taste. Continue flushing until there is no off taste. 

K. Activate "CO2 Sol L" and "CO2 Sol R" in Manual On/Off" menu. Evacuate cylinders of 

product. Pull faceplate relief valve to purge all the air from the chambers. Repeat this step 

three (3) times on each chamber, then deactivate "CO2 Sol L" and "CO2 Sol R". 

9. BASICS OF OPERATION 

9.1 MAKING ADJUSTMENTS TO THE FBD500 

A. In order to produce a consistent, quality beverage with the FBD500 Frozen Beverage Machine, 

there are a few critical settings that must be maintained. These settings are preset when you 

receive the machine from the factory, but, due to variations that occur (e.g., in operating 

environments, syrups, and individual machines, etc.), it may be necessary to make minor 

adjustments to these critical settings. Adjustments are easily made using the keypad located 

behind the door at the front of the machine, or by adjusting the CO2 regulator located behind 

the access panel below the keypad. 

B. The settings that control product quality and production rate are: 

1. Beverage Syrup Content or Brix Level (Set on syrup flow control) 

2. Liquid Level Control 

3. CO2 Injection Pressure and Chamber Operating Pressure 

4. Freeze and Thaw Settings 

20

C. In Sections 6 and 7 of this manual are instructions on machine installation and initial operation. 

These instructions should be followed for initial setup of the machine. If the product quality is 

not as desired after the initial defrost and freezedown, the critical settings should be checked 

and adjusted as necessary. This following sections discuss the sequence and method to verify 

these settings. These five (5) critical settings are explained here to help better your 

understanding of how the machine operates so you can make adjustments, if necessary. 

NOTE 

On an initial freeze down, products must be given adequate time to absorb CO2. Until CO2 is 

properly and adequately absorbed, drinks could be too “wet” or too “heavy” - conversely, if 

adjustments to drink quality are made too late, the drink could become too “dry” or too “light”. 

1. Adjusting the Brix Level 

a. Consistent, high quality beverages require adjusting and maintaining the syrup content 

of the drink or brix level between 13.5 and 15. A brix level lower than 13.0 causes 

operational problems. A low brix level (lower than 13.0) will not maintain a consistent 

quality and tends to freeze around the beater shaft. A high brix level (higher than 15.0) 

causes freezedown times to be longer and produces a more liquid but acceptable drink. 

2. Liquid Level Control 

a. The FBD500 frozen beverage dispenser utilizes a proprietary liquid level control system 

(patents pending) to hold a constant liquid level. A constant liquid level assures a 

consistent quality frozen product. 

b. If a more “wet” product is desired, the numerical setting (0-6) should be increased. If a 

“drier” and colder product is desired, the numerical setting should be decreased. 

c. The default value set at the factory is 3. This setting should produce an excellent 

quality product. 

3. CO2 Injection Pressure and Chamber Operation Pressure 

a. The CO2 injection pressure is set by adjusting the regulator, located behind the access 

panel below the control panel in the front of the machine. The CO2 injection pressure 

setting works along with the operating pressure setting to control the pressure in the 

chambers. Operating pressures should be maintained at between 25 and 30 PSIG 

(172.5 and 206.8 KPa). To achieve this range, the CO2 regulator should be set at 

30-32 PSIG (206.8 to 220.8 KPa). The unit then automatically sets the chamber 

pressure between 25 and 30 PSIG (172.5 and 206.8 KPa). 

b. Note that “cola syrups” produce a better product with a lower chamber pressure. In 

tests, chamber pressures of 25-28 PSIG (172.5 and 193.2 KPa) produced the best 

results. 

c. To lower the chamber pressure for a cola syrup, reduce the CO2 regulator pressure to 

30 PSIG (206.8 KPa). 

4. Thaw and Freeze Settings 

a. The Thaw and Freeze settings signal the refrigeration system when to start freezing and 

when to stop freezing. The liquid in the chamber freezes until it reaches the desired 

frozen consistency; then, it begins to thaw. The liquid continues to thaw until the 

consistency specified by the Thaw value. The Thaw value is the point at which the 

refrigeration system turns on and refreezes the product. The product is maintained in a 

good acceptable quality frozen drink range. 

b. Prior to changing any Thaw or Freeze settings, make sure the liquid level control 

settings are properly set and the chambers stay filled to the proper levels with the 

proper amount of CO2. The optimum frozen drink temperature is 24°F to 28°F (-4.4°C 

to -2.2°C). A product at this temperature will form a “peak” and not shrink when drawn. 

CAUTION 

IF THE THAW - FREEZE IS SET AT A LOWER SETTING, COMPRESSOR “SHORT 

CYCLE” CAN OCCUR THAT WILL CAUSE THE COMPRESSOR TO OVERHEAT. IF A 

21

LOWER SETTING IS USED, THE DISPENSER OPERATION MUST BE MONITORED TO 

INSURE THE COMPRESSOR DOES NOT “SHORT CYCLE”. 

c. The Thaw and Freeze settings may be raised or lowered to change the temperature of 

the product. A default setting of 3 is set at the factory. To decrease the temperature, 

decrease the numerical setting to 2 or 1; to increase the temperature, increase the 

numerical setting to 4 or 5. 

5. Refrigeration Settings 

CAUTION 

IN A NORMAL CONFIGURATION, THE REFRIGERATION SYSTEM IS SEALED AND 

PRESSURES CANNOT BE MONITORED. IF THE SEALED SYSTEM IS OPENED 

WITHOUT APPROVED FACTORY SERVICE, WARRANTIES WILL BE VOID. 

CAUTION 

DO NOT PRESSURIZE THE LOW SIDE (EVAPORATOR AND COMPRESSOR SECTION) 

ABOVE 150 PSIG (1035 KPA) FOR ANY REASON. COMPONENTS WILL FAIL AND 

WARRANTIES WILL BE VOID. 

a. The refrigeration settings control the rate that the chamber freezes from back to front. 

If the refrigeration settings are adjusted properly, the suction pressure of the 

compressor should read 34 to 44 PSIG (234.6 to 303.6 KPa) with one side freezing. 

When both chambers are freezing, suction pressures range from 44 to 50 PSIG (303.6 

to 345.0 KPa). If suction pressures read lower than indicated here, then only the rear 

of the chamber will freeze and the front of the chamber will remain liquid. Low suction 

pressure will also cause the compressor to short cycle. 

b. Discharge pressures that exceed 300 PSIG (2070.0 KPa) are caused by elevated room 

temperatures that cause higher condensing temperatures. This will reduce machine 

capacity. A continuing pressure above 350 PSIG (2415 KPa) may damage the 

compressor and extends freeze times. 

c. Before making changes to any of the settings, run the machine for a period of 

time. The preset values do not usually require any changes. This is a base setting and 

should not be changed without factory instructions. 

10. CHANGING FACTORY SET LIQUID LEVEL CONTROL 

The factory setting of the liquid level control may be changed to alter the quality of the product. Adjusting 

the liquid level control is allowed to change a drink that is too liquid or one that is frozen too hard. A 

product that is frozen too hard will not allow the chamber to stay full and the drink will dispense with 

sudden releases of CO2 (“spitting”). A “too full” chamber may cause a “too wet” drink. 

10.1 BEFORE CHANGING LEVEL CONTROL SETTINGS 

A. Each machine ships with preset level control values. These values should be correct for 

normal operation of the machine and should not have to be modified. 

B. Before making any changes to the level control settings, defrost both chambers by 

pressing the “DEF” buttons located on the control panel. The machine may 

automatically correct any problems with drink quality after going through a defrost cycle. 

C. After the defrost cycle, the compressor may cycle on and off several times to insure that the 

product is uniformly frozen. Wait several minutes before judging the quality of the product. 

D. If factory level control settings are correct, the product should freeze to a proper frozen 

consistency, thaw and refreeze to the same consistency. 

E. The level control settings of each drink chamber are preset to a default value of three (3). If the 

secondary regulator inside the unit is properly set to 30-32 PSIG (206.8 to 220.8 KPa), the 

chamber pressure will be “set” automatically. 

F. After the machine is installed and each chamber is properly filled, press the “DEF” button on the 

control panel to allow the machine to automatically “baseline”. Baselining indicates to the 

machine that the chamber contains liquid. As a result, the machine sensors determine how 

much to freeze the product. 

G. The display will flash “DEFROSTING” until baselining is complete. The machine will 

22

automatically start running if the machine was running when the defrost cycle was started. If the 

machine was not running before the defrost cycle started, the “RUN” button must be pressed. 

Note that there may be a delay of up to two (2) minutes before the machine turns on after the 

“RUN” button is pushed. This delay is normal. Do not press the button again or press any other 

buttons until the machine starts. 

10.2 CHANGING THE DEFAULT LEVEL CONTROL SETTING 

A. The level control setting is preset at the factory at a value of 3. 

B. If the drink is not frozen enough, or if the drink is too hard and too cold and dispenses slowly, 

after the machine has been running for 10 to 15 minutes, it may be necessary to adjust the level 

control settings. 

C. To change the machine’s level control settings, access the level two service menu. 

1. Access the service level by pressing the “FWD” button on the control panel until the 

“SERVICE MENU” displays. Press the unmarked button on the right side of the panel. 

“Machine Settings” displays. 

2. Press the “SELECT” button, “L Side Settings” displays. 

3. Press “SELECT” and “Level Control” displays. 

4. Press the “SELECT” button and the default settings of “3” begins to flash. The level is raised 

by pressing the “FWD” button and lowered by pressing the “BACK” button. When the 

desired number is reached, press “SELECT” and the new setting stops flashing and is set 

into the computer. 

D. To change the other chamber settings, press “CANCEL”, “L Side Settings” re-displays; then 

press “FWD”, “R Side Settings” displays. Repeat steps 3 and 4 above. 

E. When settings are complete, press the “CANCEL” button until “Copyright” displays. 

10.3 DRINK TOO HARD AND COLD 

A. If the drink is too hard and cold or the chamber is not full, adjust the “level control” to a higher 

level setting. Use the recommended settings that follow to properly adjust the liquid level 

control settings. 

B. It will be necessary to drain off several drinks to allow the chamber to fill and rebalance. It is 

then necessary to defrost the chamber and allow the product to refreeze. If the drink is still too 

hard, repeat the process taking the level control setting to the next higher value. 

10.4 DRINK TOO LIQUID 

A. If the drink is cold, but is still a liquid, adjust the level control to a lower level setting. Use the 

recommended settings that follow to properly adjust the level control. 

B. It will be necessary to drain off several drinks to allow the chamber to fill and rebalance. It is 

then necessary to defrost the chamber and allow the product to refreeze. If the drink is still too 

liquid, repeat the process taking the level control to the next lower setting. 

C. If the product is still too liquid, it may be necessary to adjust the THAW-FREEZE beater 

settings. Refer to Section 11 (Changing Factory Thaw and Freeze Settings) of this manual. 

D. Drink temperature should be between 24°F and 28°F (-4.4°C to -2.2°C).

11. CHANGING FACTORY THAW AND FREEZE SETTINGS 

11.1 BEFORE CHANGING THAW AND FREEZE SETTINGS 

A. Each machine ships with THAW and FREEZE values preset. These values should be correct 

for normal operation of the machine. 

B. Before changing the THAW or FREEZE settings, verify that the level control and Brix settings 

are properly set. After verifying the liquid level control, defrost both chambers by pressing the 

“DEF” buttons located on the control panel. The machine may correct any problems with drink 

quality after going through a defrost cycle. 

1. After the defrost and refreeze cycle, the compressor may cycle on and off several times to 

insure that the product is uniformly frozen. Wait several minutes before judging the quality 

of the product. 

2. The product should freeze to a proper frozen consistency, thaw, and refreeze to the same 

consistency. The compressor turns on when the thawed product requires refreezing. 

3. If the product is freezing too cold and hard, the drink dispenses slowly and the 

THAW - FREEZE value must be increased. If the product is not frozen enough (still liquid), 

the THAW - FREEZE value must be decreased. Use the recommended settings that follow 

when making adjustments to the THAW - FREEZE value.

12. CRITICAL INFORMATION 

The following information is critical to proper machine operation. Prior to troubleshooting problems with 

the unit, review the following information. 

12.1 DEFROST AND RUN TIME DELAY 

When either the RUN or the DEF button on the control panel is pressed, THE MESSAGE 

“RUN BEATER” or “DEF BEATER” is displayed. This is a time delay before the compressor starts 

running. The delay can be as long as two (2) minutes before the unit starts running or defrosting. 

Do not press the buttons again. Wait, and the machine will start freezing. 

12.2 CHAMBERS 90% FULL ON INITIAL SET UP 

When a RUN-FREEZE cycle starts, the chambers should be filled approximately 90% full. If the 

chambers are totally full, open the dispensing valve and allow a small amount of liquid to drain out. 

If the chambers are 50-60% full, press “OFF” and “FILL”; the vent ring on the faceplate will vent gas 

and allow liquid to fill if pulled. To fill the chamber, press the FILL button. The screen will display 

“Fill On”. The chamber will not fill if the pressure in the chamber is above the fill pressure. Pull the 

vent ring to lower the chamber pressure. 

12.3 LINE VOLTAGE DROP 

The unit requires a separate electrical circuit complete with a 30 AMP breaker or fuse and a 30 AMP 

service. The unit will not function properly if the line voltage drops more than 10 volts between the 

power source and the machine. 

12.4 LONG TUBING RUNS 

A. Long runs of supply tubing can cause problems if the pressure drop between the tank and the 

unit is too much. Runs longer than 30 feet (9.14 m) will require special attention. 

B. Installations requiring long runs of tubing [30 to 50 feet (9.14 to 15.24 m)] may encounter 

problems. The machine’s sensors may indicate that the machine is out of syrup or water. 

Consider the following solutions: 

1. Increase the tubing size from 1/4 inch diameter to 3/8 inch diameter. 

2. Install booster pumps in the supply lines with a vacuum regulating valve. 

3. Increase primary CO2 regulator pressure from bulk or tank CO2 to 105 - 120 PSIG (723.9 

to 827.4 KPa).
