MECHANICAL TEMPERATURE CONTROLS

COIL SENSING

An evaporator coil sensing temperature control ensures that the evaporator coil will remain clear of frost and ice by not allowing the compressor to restart until the coil temperature is above the freezing temperature. This is considered an off cycle defrost.

MECHANICAL CONTROL DELI DISPLAY GENERAL SEQUENCE OF OPERATION

1. Cabinet is plugged in.

a. Interior lights will illuminate. If lights do not come on verify the light switch is in the “ON” position.

2. A . The compressor and evaporator fans will start on a model TCGR if the temperature control is calling for cooling.

(If the compressor does not star t, verify that the temperature control is not in the “OFF” or “0” position.)

www

.truemfg.com

B. The compressor will start on models TSID, TDBD, and TCGG if the temperature control is calling for cooling.

(The above 3 models are a gravity style coil design and do not have an evaporator fan motor.)

3. The temperature control may cycle the compressor and evaporator fan(s) on and off together.

a. The temperature control is sensing the evaporator coil temperature.

b. The temperature control should be set on the #4 or #5.

c. The warmest setting is #1, the coldest is #9, and #0 is the off position.

d. The thermometer is designed to read and display a cabinet temperature not a product temperature. The thermometer may reflect the refrigeration cycle swings of up and down temperatures. The most accurate temperature on a cabinet's operation is to verify the product temperature.

4. A. There is not a defrost timer on a model TCGR as the temperature control will initiate the off-cycle defrost during each refrigeration cycle.

a. At this time, the compressor will turn off. No heaters will be energized.

b. Af ter the evaporator coil temperature has been reached determined by the temperature control, the compressor will restart.

B. The defrost timer will initiate defrost on models TSID, TDBD, and TCGG during specific times of day.

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 thir ty 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 most of the reach-in units the condenser is accessible in the rear of the unit. You must remove the cabinet grill to expose the Condenser.

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. Remove the louvered grill.

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.

(CAUTION MUST BE USED TO AVOID EYE INJURY. EYE PROTECTION IS RECOMMENDED.)

5. When finished be sure to replace the louvered grill. The grill protects the condenser.

6. Reconnect the electrical power to the unit.

If you have any questions, please call TRUE Manufacturing at 636240-2400 or 800-325-6152 and ask for the Service Depar tment. Direct to Service Department 1(855)372-1368.

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 lef t on your stainless steel can leave spots. You may have hard or sof t water depending on what par t of the country you live in. Har d water can leave spot s. 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 f ilm 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. Benef it, 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 cer tain 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 streng th (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
