DEFROST TIMER

DEFROST TIME CLOCK OPERATION FOR UNITS WITH MECHANICAL CONTROL

RECOMMENDED DEFROST SETTINGS:

TRUE Manufacturing has factory set your defrost time clock to a recommended time and duration defrost scenario. All refrigeration equipment operating below 30°F will accumulate frost on the evaporator coil and will require routine defrost. Your TRUE equipment has been designed for three defrost periods. If you decide to deviate from these defrost time settings please follow the procedures for adjustment below.

TOOLS REQUIRED

• Phillips Head Screwdriver
• 1/4 Nut Driver or Socket

SETTING THE TIMER:

UNPLUG UNIT FROM POWER SUPPLY! DO NOT SET THE TIME BY ROTATING THE OUTER DIAL. Turn the minute hand clockwise until the time of day on the outer dial is aligned with the triangle marker on the inner dial (two o’clock position).

ADJUSTING THE DEFROST TIMER

Your TRUE freezer contains a defrost system that is temperature terminated, however the time clock has been designed with a time termination back-up so that the defrost period will not exceed thirty minutes. While TRUE requires a minimum 3 defrost periods not to exceed 30 minutes the procedure on this page should be followed to customize your specific needs.

NOTICE
If timer is not set for a minimum of 3 defrost per day for 30 minutes each, the coil may develop excessive frost. This may lead to system failure and product loss, which is not covered under warranty. The following procedure may be followed to customize your needs. High usage, high temperature, and high humidity may require 4 defrost settings per day.  Always follow the manufacturer’s recommended settings when programming the amount and duration of the defrost cycles.

STEP 1

The white tabs located on the outmost area of the time clock have been factory set. Each tab represents 15 minutes of defrost time. Notice that at each defrost time two white tabs are set for 15 minutes each for a total of 30 minutes of defrost.

STEP 2

In order to program the time to begin the defrost cycle, flip the white tabs out to set the defrost time. To eliminate a defrost time flip the white tabs back toward the center of the Defrost Timer.

STEP 3

TRUE recommends a 30 minute defrost cycle three times per day.

3. Interior light will illuminate on Glass Door Models only.
4. Solid door cabinet lights are controlled by the door switch.
5. After the LAE control preprogrammed time delay of up to 6 minutes, the compressor and evaporator fans will start if the control is calling for cooling.
6. 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.
7. The LAE control will cycle the compressor but may also cycle evaporator fans on and off determined by the Set Point and Differential temperatures.
8. The Set-Point is the adjustable preprogrammed temperature which shuts off the compressor and evaporator fan(s).
9. This is not the programmed cabinet temperature.
10. 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).
11. The LAE control is designed to read and display a cabinet temperature not a product temperature.
12. This cabinet temperature may reflect the refrigeration cycle of the Set-Point and its Differential, or it may show an average temperature.
13. The most accurate temperature on a cabinets operation is to verify the product temperature.
14. The LAE control may be preprogrammed to initiate defrost by interval or at specific times of day.
15. At this time the dEF will appear on the display and compressor will turn off until a preprogrammed temperature or duration is reached.
16. During this time for freezers only, evaporator fans 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.
17. 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 Wrenc
• Air Tank or CO2 Tank
• Vacuum Cleaner

STEP 1

Disconnect power to unit.

STEP 2

Remove all screws securing top screen to unit.

STEP 3

Clean off accumulated dirt from the condenser coil and the fan with a stiff bristle brush. After brushing the components off vacuum all dirt residue from the coil, fan, and surrounding areas.

NOTE

If you cannot completely clean the condensing coil due to its position, then the front louvered panel will need to be removed.

Disconnect digital temperature control connections.

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 refrigera-tion service company. On the Spec Series units the condenser is accessible on the top of the unit. You must lift open the cabinet rain shield 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 rain shield.
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

When finished be sure to close the rainshield. 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.

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

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

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.

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.

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.

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.

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.

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. HYDROCHLORIC ACID (MURIATIC ACID) SHOULD NEVER BE USED ON STAINLESS STEEL REGULARLY RESTORE/PASSIVATE STAINLESS STEEL.
