OPERATION

STARTUP

• A. The compressor is ready to operate. Plug in the cooler.

• B. Temperature controls are factory-set to give refrigerators an approximate temperature of 35°F (1.6°C) and freezers an approximate temperature of -10°F (-23.3°C). Allow unit to function several hours, completely cooling cabinet before changing the control setting.
  Temperature Control Location and Settings.

  • Temperature control type will vary upon model and age of cabinet.
  • Mechanical control or electronic control without display:
  • Inside cabinet
  • Behind cabinet
  • Behind front or rear access grill
  • Electronic control with display:
  • In countertop
  • In top louvered panel
  • In or behind bottom louvered grill

• C. Excessive tampering with the control could lead to service difficulties. Should it ever become necessary to replace temperature control, be sure it is ordered from your TRUE dealer or recommended service agent.

• D. Good air flow in your TRUE unit is critical. Be careful to load product so that it neither presses against the back wall, nor comes within four inches of the evaporator housing. Refrigerated air off the coil must circulate down the back wall.

NOTE: If the unit is disconnected or shut off, wait five minutes before starting again.
RECOMMENDATION – Before loading product we recommend you run your TRUE unit empty for two to three days. This allows you to be sure electrical wiring and installation are correct and no shipping damage has occurred. Remember, our factory warranty does not cover product loss!

ELECTRONIC TEMPERATURE CONTROLS

LAE ELECTRONIC TEMPERATURE CONTROL GENERAL SEQUENCE OF OPERATION

• t1 = Thermostat
• t2 = Defrost
• t3 = Display

LAE ELECTRONIC CONTROL GENERAL SEQUENCE OF OPERATION

1. Cabinet is plugged in.

   • a. Display will illuminate.
   • b. I nterior light will illuminate on Glass Door Models only. Solid door cabinet lights are controlled by the door switch.

2. After the LAE control preprogrammed time delay of up to 6 minutes, the compressor and evaporator fan(s) will start if the control is calling for cooling.

   • a. Control or condenser fans may be already pre-programmed from the factory so at the start of every compressor cycle or during a defrost cycle, the condenser fan(s) will reverse for 30 seconds to blow dirt off the condensing coil.

3. The LAE control will cycle the compressor but may also cycle evaporator fan(s) on and off determined by the Set-Point and Differential temperatures.

   • a. The Set-Point is the adjustable preprogrammed temperature which shuts off the compressor and evaporator fan(s).
     This is not the programmed cabinet temperature.

   • b. The Differential is the non adjustable preprogrammed temperature that is added to the Set-Point temperature that will restart the compressor and evaporator fan(s).

   • c. The LAE control is designed to read and display a cabinet temperature not a product temperature.
     This cabinet temperature may reflect the refrigeration cycle of the Set-Point and its Differential, or it may show an average temperature.
     The most accurate temperature on a cabinets operation is to verify the product temperature.

4. The LAE control may be preprogrammed to initiate defrost by interval or at specific times of day.

   • a. At this time the “dEF” will appear on the display and compressor will turn off until a preprogrammed temperature or duration is reached. During this time for freezers only, evaporator fan(s) will also turn off and the coil heater and drain tube heaters will also be energized. Some cabinets may also change the rotation of the reversing condenser fan motor.
   • b. After the preprogrammed temperature or duration for defrost has been reached there may be a short delay for both the compressor and evaporator fans to restart. At this time “dEF” may still appear on the display for a short time.

MAINTENANCE, CARE, CLEANING

CLEANING THE CONDENSER COIL
When using electrical appliances, basic safety precautions should be followed, including the following. Disconnect power to unit.

TOOLS REQUIRED

• Phillips Screwdriver
• Stiff Bristle Brush
• Adjustable Wrench
• Air Tank or CO2 Tank
• Vacuum Cleaner

CAUTION: Before performing service or maintenance make sure louver grill is secured in open position. Use instructions and photos below to secure louver grill.

1. Remove thumbscrews on the top of each cabinet end.

2. Lift louver grill (careful not to pull on any wires)

3. Reinstall thumbscrews

   • A. The thumbscrews should be put through louver grill holes and fastened into previous position in cabinet end.
     CAUTION: Make sure top louver grill is correctly seated in the open position when servicing or cleaning.

   • B. When servicing is complete remove thumbscrews and close louver grill. Then reinstall thumbscrews into original location.

While cleaning condenser coil lift and hold top louvered grill. Clean off accumulated dirt from the condenser coil with a stiff bristle brush. Vacuum all dirt residue from the coil and surrounding areas while holding the top louvered grill. Any servicing to condensing unit remove top louvered grill. On top of the cabinet are two screws are located on either side of the louver grill. Remove these screws from the hinges and keep them in a safe place while servicing the unit. These screws are needed for later re-install of the louver grill.

IMPORTANT WARRANTY INFORMATION
Condensers accumulate dirt and require cleaning every 30 days. Dirty condensers result in compressor failure, product loss, and lost sales… which are not covered by warranty. If you keep the Condenser clean you will minimize your service expense and lower your electrical costs. The Condenser requires scheduled cleaning every thirty days or as needed. Air is pulled through the Condenser continuously, along with dust, lint, grease, etc. A dirty Condenser can result in NON-WARRANTEED part & Compressor Failures, Product Loss, and Lost Sales. Proper cleaning involves removing dust from the Condenser. By using a soft brush, or vacuuming the Condenser with a shop vac, or using CO2, nitrogen, or pressurized air. If you cannot remove the dirt adequately, please call your refrigeration service company. On the Spec Series units the condenser is accessible on the top of the unit. You must lift open the cabinet rainshield to expose the Condenser. (Spec Series models) The Condenser looks like a group of vertical fins. You need to be able to see through the condenser for the unit to function at maximum capacity. Do not place filter material in front of condensing coil. This material blocks air-flow to the coil similar to having a dirty coil.

THE CLEANING OF THE CONDENSER IS NOT COVERED BY THE WARRANTY!
HOW TO CLEAN THE CONDENSER:

1. Disconnect the electrical power to the unit.
2. Open the rainshield.
3. Vacuum or brush the dirt, lint, or debris from the finned condenser coil.
4. If you have a significant dirt build up you can blow out the condenser with compressed air.
5. When finished be sure to close the rainshield.
6. Reconnect the electrical power to the unit.

If you have any questions, please call TRUE Manufacturing at 636-240- 2400 or 800-325-6152 and ask for the Service Department. Direct to Service Department 1(855)372-1368. Service Department Availability Monday-Thursday 7:00 a.m. to 7:00 p.m., Friday 7:00 a.m. to 6:00 p.m. and Saturday 8:00 a.m. to 12:00 p.m. CST.

STAINLESS STEEL EQUIPMENT CARE AND CLEANING

CAUTION: Do not use any steel wool, abrasive or chlorine based products to clean stainless steel surfaces.
STAINLESS STEEL OPPONENTS
There are three basic things which can break down your stainless steel’s passivity layer and allow corrosion to rear its ugly head.

1. Scratches from wire brushes, scrapers, and steel pads are just a few examples of items that can be abrasive to stainless steel’s surface.
2. Deposits left on your stainless steel can leave spots. You may have hard or soft water depending on what part of the country you live in. Hard water can leave spots. Hard water that is heated can leave deposits if left to sit too long. These deposits can cause the passive layer to break down and rust your stainless steel. All deposits left from food prep or service should be removed as soon as possible.
3. Chlorides are present in table salt, food, and water. Household and industrial cleaners are the worst type of chlorides to use.

RECOMMENDED CLEANERS FOR CERTAIN SITUATIONS / ENVIRONMENTS OF STAINLESS STEEL

• A. Soap, ammonia and detergent medallion applied with a cloth or sponge can be used for routine cleaning.
• B. Arcal 20, Lac-O-Nu Ecoshine applied provides barrier film for fingerprints and smears.
• C. Cameo, Talc, Zud First Impression is applied by rubbing in the direction of the polished lines for stubborn stains and discoloring.
• D. Easy-off and De-Grease It oven aid are excellent for removals on all finishes for grease-fatty acids, blood and burnt-on foods.
• E. Any good commercial detergent can be applied with a sponge or cloth to remove grease and oil.
• F. Benefit, Super Sheen, Sheila Shine are good for restoration/passivation.

NOTE: The use of stainless steel cleaners or other such solvents is not recommended on plastic parts. Warm soap and water will suffice.

8 STEPS THAT CAN HELP PREVENT RUST ON STAINLESS STEEL:

1. USING THE CORRECT CLEANING TOOLS
   Use non-abrasive tools when cleaning your stainless steel products. The stainless steel’s passive layer will not be harmed by soft cloths and plastic scouring pads. Step 2 tells you how to find the polishing marks.

2. CLEANING ALONG THE POLISH LINES
   Polishing lines or “grain” are visible on some stainless steels. Always scrub parallel to visible lines on some stainless steels. Use a plastic scouring pad or soft cloth when you cannot see the grain.

3. USE ALKALINE, ALKALINE CHLORINATED OR NON-CHLORIDE CONTAINING CLEANERS
   While many traditional cleaners are loaded with chlorides, the industry is providing an ever increasing choice of non-chloride cleaners. If you are not sure of your cleaner’s chloride content contact your cleaner supplier. If they tell you that your present cleaner contains chlorides, ask if they have an alternative. Avoid cleaners containing quaternary salts as they can attack stainless steel, causing pitting and rusting.

4. WATER TREATMENT
   To reduce deposits, soften the hard water when possible. Installation of certain filters can remove corrosive and distasteful elements. Salts in a properly maintained water softener can be to your advantage. Contact a treatment specialist if you are not sure of the proper water treatment.

5. MAINTAINING THE CLEANLINESS OF YOUR FOOD EQUIPMENT
   Use cleaners at the recommended strength (alkaline chlorinated or non- chloride). Avoid build-up of hard stains by cleaning frequently. When boiling water with your stainless steel equipment, the single most likely cause of damage is chlorides in the water. Heating any cleaners containing chlorides will have the same damaging effects.

6. RINSE
   When using chlorinated cleaners you must rinse and wipe dry immediately. It is better to wipe standing cleaning agents and water as soon as possible. Allow the stainless steel equipment to air dry. Oxygen helps maintain the passivity film on stainless steel.

7. HYDROCHLORIC ACID (MURIATIC ACID) SHOULD NEVER BE USED ON STAINLESS STEEL

8. REGULARLY RESTORE/PASSIVATE STAINLESS STEEL
