STORE CONDITIONSThe Master-Bilt TEL/TEM cases are designed to operate in the controlled environment of an air conditioned store. Thestore temperature should be at or below 75°F and a relative humidity of 55% or less. At higher temperature or humidityconditions, the performance of these cases may be affected and the capacity diminished. It is not uncommon in a newlyconstructed store for the temperature and humidity to be above design conditions. These excessive conditions mayproduce sweating in the case until the store is operational and the ambient environment is more desirable.LOCATIONThe Master-Bilt TEL/TEM should not be positioned where it is directlyexposed to rays of the sun or near a direct source of radiant heat or airflow.Cabinet should not be built into an enclosed area. If this case is to belocated against a wall there should be at least a 4” space between thewall and the back of the case, with 4” open space at top and one or bothends. This space will allow for the circulation of air behind the casewhich will prevent condensation on the exterior surfaces.Make sure that the floor that will support this equipment is of adequatestrength to prohibit sagging. After confirming the dimensions of case withthe blueprint measure off and mark on the floor the exact location of thecases for the entire lineup. Snap chalk lines where the base skids of thecase are to be located as shown in Figure 1.Figure 17

LEVELINGIt is very important that this equipment be perfectly level. This will allow for proper and complete drainage of theevaporator coil and for proper case alignment. A perfectly level area is generally not available where the equipment is tobe installed. Mark the location of all case joining points front and back. Use a transit to locate the highest point on thechalk lines. This point will be a reference point for determining shim-pack heights. Using the reference point, mark thedifference directly on the floor to each joining point front and back. Shim each joining point to equal the reference pointas required. Tape all shims in place. If the installation is an entire lineup install the case that will be positioned at thehighest point first. Check that the equipment in the lineup is level as the installation proceeds.JOINING SECTIONS, TEL/TEMRemove the case from its shipping skid. Set the first caseinto its desired position with required shims in preparationfor joining it with its adjacent case.The joining gasket for cases in a lineup is factory installedand is shown in balck in Figure 2. This gasket is onlyrequired on one end of cases in a lineup as only onegasket is needed between two cases. Inspect the gasketinsure that it is properly located and is not damaged.Remove the protective covering on the outside face of theadjoining tape. The cases are now ready to be joinedtogether. Remove the second case from its shipping skid,remove the “X” braces from the open end of the sections,and move it into position against the end of the first case.Properly level the second case with the appropriate shimstoBolt the cases together through the eight holes that areprovided in the aluminum triangular gussets as shown inFigure 4. Tighten the bolts until all seams are fully closed.Do not over tighten.Figure 4GASKETSUPPORT POSTDOOR FRAMETo join the door frames, drill through the support posts with 9/64”drill, using countersunk holes as a guide. Use the long screws (inthe bag tied to the door handle) to draw the frames together. SeeFigure 5.Figure 510

REFRIGERATION SYSTEM EVACUATING AND CHARGING1. Blow out all refrigerant lines with dry nitrogen or carbon dioxide to eliminate the possibility ofdirt, scale, etc. remaining inside.2. Connect all lines and leak test all connections.3. Connect a good high vacuum pump to both the low and high side evacuation valves.4. Operate the pump until a vacuum of 1500 microns (0.06 inches of mercury) absolute pressure is obtained. At thispoint, the vacuum should be broken by the introduction of refrigerant into the system, through a drier, until thepressure is brought up to zero pounds gauge. Repeat this procedure two more times. During the final evacuation, avacuum of 500 microns (0.02 inches of mercury) absolute pressure should be obtained. After this vacuum isreached, the system can be fully charged with refrigerant.DEFROST TERMINATION/ TEMPERATURE CONTROLSFor a TEL/TEM, the controls are located at the top of the cabinet on the right hand side. Nothing will have to be removedto access the controls.The temperature control is adjusted by simply turning the knob clockwise for a colder case and counter-clockwise for awarmer case. The defrost termination control sensor ismounted directly on the end plate of the coil. This control determines how long the defrost cycle will last. By adjusting thedefrost termination control clockwise the defrost cycle will be shortened. By adjusting the defrost termination controlcounter-clockwise the defrost cycle will become longer.CONTROL SETTINGSTEL (Low Temp)TEM (Med Temp)Temperature Control -25 - +22°F 32 - 51°FCondensing Unit Time Clock4 times/day (6hours);N/A40 minutes fail safe*Condensing Unit Low Pressure Control Cut in 20 lbs: Diff. 18 lbs.

Check the temperature holding range against the control setting.2. Check the defrost control system to see that all ice is removed from the coil during each defrost cycle.3. Check pressures.4. Check EPR Valve for proper pressure when applicable.13

FINAL CHECK LISTA. Check high-low pressure control settings.B. Check setting of defrost timer:1. Four defrost/24 hours, with 30 minute fail safe.C. Check operating pressure.D. Check electrical requirements of unit to supply voltage.E. Set temperature control for desired temperature range.F. Check setting of thermostatic expansion valve for proper operation. Approx. 10°F superheat.G. Check sight glass for proper refrigerant charge.H. Check system for proper defrost settings and operation.I. Check condensing unit for vibrating or rubbing tubing. Dampen and clamp as required.J. All valves should be completeley open counter-clockwise.K. Check packing nuts on all service valves.L. Replace all service valve caps and latch unit covers.M. Check refrigeration line for proper P-traps and proper locations.N. Check drain for proper P-traps and proper locations.DOOR PLASTIC (GASKET RETAINER) REPLACEMENTStarting in corner, gently pull the rubber gasket away from the door plastic. With gasket removed, insert a flat-headscrewdriver under the outside edge of the plastic, and gently pry up. At either end of the plastic run the screwdriver thecomplete length and width of the door rail. With the outside edge of the plastic released, push the plastic towards theglass to remove. To replace, insert the edge of the plastic into the inside door rail groove. Snap the outside edge of theplastic cover over the outside edge of the door rail.DOOR GASKET REPLACEMENTRemove the old gasket by starting in the corner, gently pulling gasket away from the plastic. To replace the gasket,remove the top and bottom door plastic, and slide the gasket up the two verticals. Slide the top and bottom plastic ontothe gasket, and replace the top and bottom plastic on the door rail. Tuck in the corners of the gasket with a flat-headscrewdriver.BALLAST REPLACEMENT, TEL/TEMFor a TEL/TEM, the magnetic ballasts are located in the raceway at the bottom of the cabinet. The kickplate will have tobe removed to access the ballasts. Consult the wiring diagrams for the TEL/TEM on pages 31 thru 34 of this manual.DOOR HEATER REPLACEMENTRemove door gasket and plastic. Remove the center side access plate located on the side of the door. The wiring forthe door is done in the center side of the hinge rail. To remove the heater, unplug the solid lead wires: Black or Red,White, and Green/Yellow (ground). If the glass is heated, unplug the Black and White solid wires from the glass. Heaterwire lies in track on the back outside edge of door. Pull the heater out. Reverse instructions to replace the door heater.Plug in Black or Red lead wire from hinge pin to Black or Red lead wire from heater, White lead wire from hinge pin toWhite heater lead, and Green/Yellow lead from hinge pin to ground.Note: If glass is heater, plug in Black and White lead wires coming off heater loom to Black and White lead wires fromglass. Replace side access plate. Replace the door plastic and gasket.14
