prevent damage. When sight glasses are being installed, remove the 

glass. Remove stems, seats, and packing of valves, and accessible 

internal parts of refrigerant specialties before brazing. Do no apply heat 

near the bulb of the expansion valve. 

2. Fill the pipe and fittings during brazing, with an inert gas (i.e., nitrogen or carbon 

dioxide) to prevent formation of scale. 

3. Heat joints using oxy-acetylene torch. Heat to proper and uniform brazing 

temperature. 

B. Equipment Connections: 

1. The Drawings indicate the general arrangement of piping and fittings. 

2. Install piping adjacent to machine to allow servicing and maintenance. 

3.8 REFRIGERANT PIPING SYSTEMS 

A. Inspect, test and perform corrective action of refrigerant piping in accordance with ASME 

Code B31.5, Chapter VI, “Refrigerant Piping and Heat Transfer Components”, 2001, and 

as follows: 

1. All refrigerant tubing shall be tested before tube insulation is applied. 

2. Note: The use of compressed air for pressure testing refrigerant tubing will not be 

permitted. 

3. Refrigerant relieve valves, if installed, shall be removed prior to pressure testing 

and shell openings plugged. After system is tested and found to be completely 

tight, relief valves shall be reinstalled prior to system evacuation. 

4. Each tubing system shall be pressure tested with dry nitrogen. Leaks shall be 

repaired by removing and remaking the defective joint. No caulking will be 

permitted. After repair of leaks, system shall be retested and provided tight. 

5. Tubing shall be tested as a minimum of 300 psig on the high side of 225 psig on 

the low side. Suggested procedure is as follows: 

a. Charge system with oil pumped dry nitrogen to a pressure of 100 psig. 

Make a soap bubble test of all joints and all connections. Mark all leaks, 

blow down and repair all leaks. 


28103.01 January 15, 2013

3.9 ADJUSTING AND CLEANING 

b. After above test and repair, charge high side with R-507 or R-12, R-22 or 

R-502 gas (based upon application) to a pressure of 30 psig. Make a 

rapid leak check at this pressure using an electronic leak detector. If no 

leaks are found, raise pressure to 300 psig on the high side of 225 psig 

on the low side using oil pumped dry nitrogen. 

c. Leave nitrogen and refrigerant mixture overnight to permit mixing by 

diffusion. Check diffusion and leak tester operation by venting a flange or 

valve stem. Make a thorough leak test. If leaks are found, blow down, 

repair and retest. Continue this procedure until entire system is provided 

to be absolutely tight. 

d. After the refrigerant piping has been pressure tested and proven tight, 

and before piping insulation s applied, the entire system shall be 

evacuated with a vacuum pump to remove air and moisture. Evacuation 

shall be performed with all spaces containing refrigerant piping or 

equipment at no lower than 50°F. 

e. Manual valves except those open to atmosphere shall be opened and all 

controls such as solenoids shall be jacked open. Any gauges or 

pressure controls which could be damaged by a deep vacuum shall be 

valved off. Seal caps on valves shall be in place and tight. Any valves 

open to atmosphere shall be closed and capped. 

f. The entire system shall be double evacuated to 1500 microns Hg 

absolute (1.5 torr) as follows: 

1) When vacuum pump is started, vacuum should pull down fairly 

rapidly to 25,000 microns Hg absolute (28.94”). If vacuum does 

not pull below 25,000 microns, there are leaks in the system and 

leak test procedure must be repeated. 

2) At approximately 10,000 microns, evaporation of free water in the 

system will be rapidly accelerated and vacuum will tend to remain 

constant as evaporation rate begins to equal vacuum pump 

capacity. Depending on amount of water, ambient temperature 

and vacuum pump capacity, it may take several hours to make 

any noticeable decrease in vacuum below 10,000 microns. 

During this period, apply heat to any low points or suspected 

points of moisture. Feel pipes for cold spots and supply heat. 

3) Continue evacuation until a pressure of 1,500 microns (1.5 torr) 

minimum is reached, then break the vacuum and pressurize to 

10 psig with oil pumped dry nitrogen as a holding charge until 

ready for charging. 

4) When ready for charging, vent nitrogen holding charge to 

atmosphere and re-evacuate down to a minimum of 1,500 

microns. Break vacuum with refrigerant gas. Do not use liquid. 

g. Repair leaking joints using new materials, and retest for leaks. 

A. Verify actual evaporator applications and operating conditions, and adjust thermostatic 

expansion valve to obtain proper evaporator superheat requirements. 

B. Clean and inspect refrigerant piping systems in accordance with industry standards. 

C. Adjust controls and safeties. Replace damaged or malfunctioning controls and 

equipment with new materials and products. 

3.10 COMMISSIONING 

A. Charge system using the following procedure: 


28103.01 January 15, 2013

1. Install core in filter dryer after leak test but before evacuation.

Upon a prediction that will exceed the user defined demand limit (supply a 

minimum of 6 per day), the demand limiting object shall issue shed commands to 

either turn off user specified loads or modify equipment set points to effect the 

desired energy reduction. If the list of sheddable equipment is not enough to 

reduce the demand to below the set point, a message shall be displayed on the 

users screen (as an alarm) instructing the user to take manual actions to 

maintain the desired demand. The shed lists are specified by the user and shall 

be selectable to be shed in either a fixed or rotating order to control which 

equipment is shed the most often. Upon suitable reductions in demand, the 

demand-limiting object shall restore the equipment that was shed in the reverse 

order in which it was shed. Each sheddable object shall have a minimum and 

maximum shed time property to effect both equipment protection and occupant 

comfort.

alarming. Also, provide a time delay filter property to prevent nuisance alarms 

caused by temporary excursions above or below the user defined alarm limits. 

2. Analog Output Object - Minimum requirement is to comply with the BACnet 

standard for data sharing. 

3. Binary Input Object - Minimum requirement is to comply with the BACnet 

standard for data sharing. The user must be able to specify either input condition 

for alarming. This object must also include the capability to record equipment 

run-time by counting the amount of time the hardware input is in an “on” 


FOR HVAC 

28103.01 January 15, 2013

condition. The user must be able to specify either input condition as the “on” 

condition. 

4. Binary Output Object - Minimum requirement is to comply with the BACnet 

standard for data sharing. Properties to enable minimum on and off times for 

equipment protection as well as interstart delay must be provided. The BACnet 

Command Prioritization priority scheme shall be incorporated to allow multiple 

control applications to execute commands on this object with the highest priority 

command being invoked. Provide sixteen levels of priority as a minimum. 

Systems not employing the BACnet method of contention resolution shall not be 

acceptable. 

5. PID Control Loop Object - Minimum requirement is to comply with the BACnet 

standard for data sharing. Each individual property must be adjustable as well as 

to be disabled to allow proportional control only, or proportional with integral 

control, as well as proportional, integral and derivative control. 

6. Comparison Object - Allow a minimum of two analog objects to be compared to 

select either the highest, lowest, or equality between the two linked inputs. Also, 

allow limits to be applied to the output value for alarm generation. 

7. Math Object - Allow a minimum of four analog objects to be tested for the 

minimum or maximum, or the sum, difference, or average of linked objects. Also, 

allow limits to be applied to the output value for alarm generation. 

8. Custom Programming Objects - Provide a blank object template for the creation 

of new custom objects to meet specific user application requirements. This object 

must provide a simple BASIClike programming language that is used to define 

object behavior. Provide a library of functions including math and logic functions, 

string manipulation, and e-mail as a minimum. Also, provide a comprehensive 

on-line debug tool to allow complete testing of the new object. Allow new objects 

to be stored in the library for re-use. 

9. Interlock Object - Provide an interlock object that provides a means of 

coordination of objects within a piece of equipment such as an Air Handler or 

other similar types of equipment. An example is to link the return fan to the 

supply fan such that when the supply fan is started, the return fan object is also 

started automatically without the user having to issue separate commands or to 

link each object to a schedule object. In addition, the control loops, damper 

objects, and alarm monitoring (such as return air, supply air, and mixed air 

temperature objects) will be inhibited from alarming during a user-defined period 

after startup to allow for stabilization. When the air handler is stopped, the 

interlocked return fan is also stopped, the outside air damper is closed, and other 

related objects within the air handler unit are inhibited from alarming thereby 

eliminating nuisance alarms during the off period. 

10. Temperature Override Object - Provide an object whose purpose is to provide 

the capability of overriding a binary output to an “On” state in the event a user 

specified high or low limit value is exceeded. This object is to be linked to the 

desired binary output object as well as to an analog object for temperature 

monitoring, to cause the override to be enabled. This object will execute a Start 

command at the Temperature Override level of start/stop command priority 

unless changed by the user. 

11. Composite Object - Provide a container object that allows a collection of objects 

representing an application to be encapsulated to protect the application from 

tampering, or to more easily represent large applications. This object must have 

the ability to allow the user to select the appropriate parameters of the 

“contained” application that are represented on the graphical shell of this 

container.
