Proper Disposal of the Freezer / Refrigerator
DANGER! RISK OF CHILD ENTRAPMENT
Child entrapment and suffocation are not problems of the past. Junked or abandoned refrigerators are still dangerous... even if they will sit for "just a few days." If you are getting rid of your old refrigerator, please follow the instructions below to help prevent accidents.
Before You Throw Away Your Old Refrigerator or Freezer:
- Take off the doors.
- Leave the shelves in place so that children may not easily climb inside.
Refrigerant Disposal
Your old refrigerator may have a cooling system that uses "Ozone Depleting " chemicals. If you are throwing away your old refrigerator, make sure the refrigerant is removed for proper disposal by a qualified service technician. If you intentionally release any refrigerants you can be subject to fines and imprisonment under provisions of the environmental regulations.
Use of Extension Cords
NEVER USE AN EXTENSION CORD! TRUE will not warranty any refrigerator that has been connected to an extension cord.
Replacement Parts
- Component parts shall be replaced with like components.
- Servicing shall be done by authorized service personnel, to minimize the risk of possible ignition due to incorrect parts or improper service.
- Lamps must be replaced by identical lamps only.
- If the supply cord is damaged, it must be replaced by a special cord or assembly available from the manufacturer or its service agent.
Connecting Electricity
WARNING! HOW TO CONNECT ELECTRICITY
Do not, under any circumstances, cut or remove the ground prong from the power cord. For personal safety, this appliance must be properly grounded.
The power cord of this appliance is equipped with a grounding plug which mates with a standard grounding wall outlet to minimize the possibility of electric shock hazard from this appliance. Have the wall outlet and circuit checked by a qualified electrician to make sure the outlet is properly grounded. If the outlet is a standard 2-prong outlet, it is your personal responsibility and obligation to have it replaced with the properly grounded wall outlet.
The refrigerator should always be plugged into its own individual electrical circuit, which has a voltage rating that matches the rating plate. This provides the best performance and also prevents overloading building wiring circuits which could cause a fire hazard from overheated wires.
Never unplug your refrigerator by pulling on the power cord. Always grip plug firmly and pull straight out from the outlet.
Repair or replace immediately all power cords that have become frayed or otherwise damaged. Do not use a cord that shows cracks or abrasion damage along its length or at either end. When removing the refrigerator away from the wall, be careful not to roll over or damage the power cord.
Use of Adapter Plugs
NEVER USE AN ADAPTER PLUG! Because of potential safety hazards under certain conditions, we strongly recommend against the use of an adapter plug.
(North America Use Only!) NEMA plugs
TRUE uses these types of plugs. If you do not have the right outlet have a certified electrician install the correct power source. The incoming power source to the cabinet including any adapters used must have the adequate power available and must be properly grounded. Only adapters listed with UL should be used.
T-72F Wiring Changes (110V Application Only)
Previous design: 4 prong plug NEMA 14-20R - 4 wire circuit (see image 1). Current design: 3 prong plug NEMA 5-20R - 3 wire circuit (see image 2).
Wiring Conversion
At Receptacle Box:
- Turn breaker off.
- Disconnect all wires from receptacle.
- Insulate red wire (tape or wire nut).
- Connect black, white, and green wires to 3 prong plug NEMA 5-20R per instructions on receptacle.
At Breaker Panel:
- With breaker turned off, remove wires.
- Remove double pole breaker.
- Install single pole breaker.
- Connect black wire to breaker.
- Insulate red wire.

NOTE: It is the customer's responsibility to make sure receptacle wiring meets all local electrical codes. TRUE recommends hiring a licensed qualified electrician to make this change.
Installation / Operation Instructions
Ownership
To ensure that your unit works properly from the first day, it must be installed properly. We highly recommend a trained refrigeration mechanic and electrician install your TRUE equipment. The cost of a professional installation is money well spent.
Before you start to install your TRUE unit, carefully inspect it for freight damage. If damage is discovered, immediately file a claim with the delivery freight carrier. TRUE is not responsible for damage incurred during shipment.
Required Tools
- Adjustable Wrench
- Phillips Head Screwdriver
- Level
Uncrating
NOTE Units with a solar thermometer will experience a 15 second delay after exposed to light before they read the proper temperature.
The following procedure is recommended for uncrating the unit:
- Remove the outer packaging (cardboard and bubbles or styrofoam corners and clear plastic). Inspect for concealed damage. Again, immediately file a claim with the freight carrier if there is damage.
- Move your unit as close to the final location as possible before removing the wooden skid.
- Remove door bracket on swinging glass door models (see image 1-2). Sliding glass door models contain shipping blocks (three for each door). Remove the two styrofoam blocks taped to the top of the door tracks (see image 3). The shipping blocks are orange in color and by opening the door a little the blocks can be removed (see images 4-6). Do not throw the bracket or blocks away. For future cabinet movement the bracket and blocks will need to be installed so the glass door does not receive any damage. (See image for bracket and shipping block removal)
NOTE Keys for coolers with door locks are located in warranty packets.
Locating
- Remove louver from the front of cabinet (see page 17 for louver grill removal / reinstallation) and backguard (if applicable) from rear of cabinet.
- Skid bolts are located in each of 4 corners inside cabinet bottom. (See photo A).
- Remove skid bolts. (See photo B).
- Cut straps if applicable. (See photo C).
- Carefully lift cabinet off of skid.
Removing skid from bottom of cabinet.
The appliance was tested according to climate classes 5 and 7 for temperature and relative humidity.
Leveling
- Set unit in its final location. Be sure there is adequate ventilation in your room. Under extreme heat conditions, (100°F+, 38°C+), you may want to install an exhaust fan.
- Proper leveling of your TRUE cooler is critical to operating success (for non-mobile models). Effective condensate removal and door operation will be affected by leveling.
- The cooler should be leveled front to back and side to side with a level.
- Ensure that the drain hose or hoses are positioned in the pan.
- Free plug and cord from inside the lower rear of the cooler (do not plug in).
- The unit should be placed close enough to the electrical supply so that extension cords are never used.
WARNING Warranty is void if ventilation is insufficient.
WARNING Cabinet warranties are void if OEM power cord is tampered with. TRUE will not warranty any units that are connected to an extension cord.

Installation of Castors or Optional Legs
Important Safeguard for installation of leg/castor (Images 1-5 demonstrate procedure)
Securing Castors and Legs
To obtain maximum strength and stability of the unit, it is important that you make sure each castor is secure. Optional legs are hand-tightened securely against the lower rail assembly (see image 4-5). The bearing race on the castor or the top edge of the leg must make firm contact with the rail.
Unit Leveling
Four leveling shims have been provided for leveling castored units positioned on uneven floors. Shims must be positioned between rail end and bearing race.
- Turn the bearing race counter-clockwise until the cabinet is level. Level front to back and side to side (diagonally).
- Install the desired number of shims, making sure the slot of the shim is in contact with the threaded stem of the castor. (See image 2).
- If more than one shim is used, turn the slot at a 90° angle so they are not in line.
- Turn the bearing race clockwise to tighten and secure the castor by tightening the anchoring bolt with a 3/4 inch open-end wrench or the tool provided. (See image 3).
CAUTION To avoid damage to lower rail assembly, slowly raise unit to upright position.
NOTE Open holes located on the cross members of the frame rail should be plugged before unit is in use.

Electrical Instructions
A. Before your new unit is connected to a power supply, check the incoming voltage with a voltmeter. If anything less than 100% of the rated voltage for operation is noted, correct immediately.
B. All units are equipped with a service cord, and must be powered at proper operating voltage at all times. Refer to cabinet data plate for this voltage.
TRUE requires that a sole use circuit be dedicated for the unit. Failure to do so voids warranty.
WARNING Compressor warranties are void if compressor burns out due to low voltage.
WARNING Power supply cord ground should not be removed!
WARNING Do not use electrical appliances inside the food storage compartments of the appliances unless they are of the type recommended by the manufacturer.
NOTE To reference wiring diagram - Remove front louvered grill, wiring diagram is positioned on the inside cabinet wall.
Sealing Cabinet to Floor
Step 1 - Position Cabinet
Allow one inch between the wall and rear of the refrigerator to assure proper ventilation. For freezers 3 inches between the wall and rear of the cabinet will assure proper ventilation.
Step 2 - Level Cabinet
Cabinet should be level, side to side and front to back. Place a carpenter's level in the interior floor in four places:
- Position level in the inside floor of the unit near the doors. (Level should be parallel to cabinet front). Level cabinet.
- Position level at the inside rear of cabinet. (Again level should be placed parallel to cabinet back).
- Perform similar procedures to steps a & b by placing the level on inside floor (left and right sides - parallel to the depth of the cooler). Level cabinet.
Step 3
Draw an outline on the base on the floor.
Step 4
Raise and block the front side of the cabinet.
Step 5
Apply a bead of "NSF Approved Sealant", (see list below), To floor on half inch inside the outline drawn. The bead must be heavy enough to seal the entire cabinet surface when it is down on the sealant.
Step 6
Raise and block the rear of the cabinet.
Step 7
Apply sealant on floor as outline in Step 5. on other three sides.
Step 8
Examine to see that cabinet is sealed to floor around entire perimeter.
NOTE Asphalt floors are very susceptible to chemical attack. A layer of tape on the floor prior to applying the sealant will protect the floor.
NSF Approved Sealants:
- Minnesota Mining #ECU800 Caulk
- Minnesota Mining #ECU2185 Caulk

Freezers Only! (Compressor Band Removal)
PLEASE CHECK YOUR COMPRESSOR. IF THERE IS A SHIPPING BAND, PLEASE REMOVE.
WARNING COMPRESSOR BAND MUST BE REMOVED BEFORE UNIT IS CONNECTED TO POWER SUPPLY.
The metal band can be reached from the rear of the unit. A pair of tin snips will cut through the band. Once the band is located and removed, you may proceed with the installation of your new equipment. (See image to the right).
Diagram showing cutting band that is around compressor.
Start-up
- The compressor is ready to operate. Plug in the cooler.
- Temperature control set at No. 4 position gives refrigerators an approximate temperature of 35°F. Allow unit to function several hours, completely cooling cabinet before changing the control setting.
- 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.
- 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 cooler 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!
Replacement Parts
TRUE maintains a record of the cabinet serial number for your cooler. If at any time during the life of your cooler, a part is needed, you may obtain this part by furnishing the model number and serial number to the company from whom you purchased the cooler. Call Toll-Free: (800)-424-TRUE (Direct to Parts Department). (800)-325-6152 (U.S.A. & Canada only) or call: (636)-240-2400.
LAE Control Sequence of Operation
IF YOUR CABINET IS BUILT WITH THIS TEMPERATURE CONTROL, PLEASE SEE THE FOLLOWING INSTRUCTIONS.
- Cabinet is plugged in.
- Display will illuminate.
- Interior light will illuminate on glass door models only. (If lights do not come on please see instructions on following page(s).) Solid door cabinet lights are controlled by door switch.
- After the LAE control preprogrammed time delay of 3 minutes, the compressor and evaporator fan(s) will start if the control is calling for cooling.
- Control 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.
- 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. (If the Set-Point needs to be changed due to conditions please see instructions on the following page(s).)
- The Set-Point is the preprogrammed temperature which shuts off the compressor.
- The Differential is the preprogrammed temperature that is added to the Set-Point temperature that will start the compressor.
- Example: If the Set-Point is -9°F/-23°C and the Differential is 10°F/5°C (Set-Point) -9°F + 10 (Differential) = 1°F Or (Set-Point) -23°C + 5 (Differential) = -18°C The compressor and evaporator fan(s) will cycle off -9°F/-23°C and back on at 1°F/-18°C
- The LAE control may be preprogrammed to initiate defrost by interval or at specific times of day. (If additional Defrost Intervals or Cycles are needed or a Manual Defrost is required due to conditions please see instructions on the following page(s).)
- 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.
- 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.
True Manufacturing recommends that ONLY the Set-Point and/or Defrost Interval may be adjusted due to certain conditions.
This sequence is NOT model specific.
If you have any questions, please contact the Technical Service Department.

Troubleshooting
IF THE COMPRESSOR WILL NOT RUN
- If there is no voltage at the compressor terminals, follow the wiring diagram and check back from compressor to the power supply to find where the circuit is interrupted.
- If power is available at the compressor terminals, and the compressor does not run, check the voltage at the compressor terminals while attempting to start the compressor. If voltage at the compressor terminals is below 90% of the nameplate voltage, it is possible the motor may not develop sufficient torque to start. Check to determine if wire sizes are adequate, electrical connections are loose, the circuit is overloaded, or if the power supply is inadequate.
- On single phase compressors, a defective capacitor or relay may prevent the compressor starting. If the compressor attempts to start but is unable to do so, or if there is a humming sound, check the relay to see if the relay contacts are damaged or fused. The relay points should be closed during the initial starting cycle, but should open as the compressor comes up to speed. Remove the wires from the starting relay and capacitors. Use a high voltage ohmmeter to check for continuity throughout the relay coil. Replace the relay if there is not continuity. Use an ohmmeter to check across the relay contacts. Potential relay contacts are normally closed when the relay is not energized, current relay contacts are normally open. If either gives an incorrect reading, replace the relay. Substitute a "known to be good" start capacitor if available. If compressor then starts and runs properly, replace the original start capacitor. If a capacitor tester is not available, an ohmmeter may be used to check run and start capacitors for shorts or open circuits. Use an ohmmeter set to its highest resistance scale, and connect prods to capacitor terminals.
- a) With a good capacitor, the indicator should first move zero, and then gradually increase to infinity.
- b) If there is no movement of the ohmmeter indicator, an open circuit is indicated.
- c) If the ohmmeter indicator moves to zero, and remains there or on a low resistance reading, a short circuit is indicated. Defective capacitors should be replaced.
- If the correct voltage is available at the compressor terminals, and no current is drawn, remove all wires from the terminals and check for continuity through the motor windings. On single phase motor compressors, check for continuity from terminals C to R, and C to S. On compressors with line break inherent protectors, an open overload protector can cause a lack of continuity. If the compressor is warm, wait one hour for the compressor to cool and recheck. If continuity cannot be established through all motor windings, the compressor should be replaced. Check the motor for ground by means of a continuity check between the common terminal and the compressor shell. If there is a ground, replace the compressor.
- If the compressor has an external protector, check for continuity through the protector or protectors. All external inherent protectors on compressors can be replaced in the field.
IF THE MOTOR COMPRESSOR STARTS BUT TRIPS REPEATEDLY ON THE OVERLOAD PROTECTOR
- Check the compressor suction and discharge pressures while the compressor is operating. Be sure the pressures are within the limitations of the compressor. If pressures are excessive it may be necessary to clean the condenser, purge air from the system, replace crankcase pressure regulating valve. An excessively low suction pressure may indicate a loss of charge. On units with no service gauge parts where pressures can be checked, check condenser to be sure it is clean and fan is running. Excessive temperatures on suction and discharge line may also indicate abnormal operating conditions.
- Check the line voltage at the motor terminals while the compressor is operating. The voltage should be within 10% of the nameplate voltage rating. If outside those limits, the voltage supply must be brought within the proper range, or a motor compressor with different electrical characteristics must be used.
- Check the amperage drawn while the compressor is operating. Under normal operating conditions, the amperage drawn will seldom exceed 110% of the nameplate amperage. High amperage can be caused by low voltage, defective running capacitors, or a defective starting relay. Any capacitor found to be bulging, leaking, or damaged should be replaced. Make sure capacitors are discharged before checking. Check for continuity between each capacitor terminal and the case. Continuity indicates a short, and the capacitor should be replaced.
- If all operating conditions are normal, the voltage supply at the compressor terminals balanced and within limits, the compressor crankcase temperature within normal limits, and the amperage drawn within the specified range, the motor protector may be defective, and should be replaced. If the operating conditions are normal and the compressor is running excessively hot for no observable reason, or if the amperage drawn is above the normal range and sufficient to repeatedly trip the protector, the compressor has internal damage and should be replaced.
IF THE COMPRESSOR RUNS BUT WILL NOT REFRIGERATE
- Check the refrigerant charge. Check the evaporator surface to determine if it is evenly cold throughout, or if partially starved. A lack of charge may be indicated by light, fluffy frost at the evaporator inlet. Add refrigerant if necessary.
- Check the compressor suction pressure. An abnormally low pressure may indicate a loss of refrigerant charge, a malfunctioning capillary tube, a lack of evaporator capacity possibly due to icing or low air flow, or a restriction in the system. Often a restriction in a drier or strainer can be identified by frost or a decrease in temperature across the restriction due to the pressure drop in the line. This will be true only if liquid refrigerant is in the line at the restricted point, since any temperature change due to restriction would be caused by the flashing of liquid into vapor as the pressure changes. Any abnormal restriction in the system must be corrected.
- Check the compressor discharge pressure. An abnormally high discharge pressure can cause a loss of capacity, and can be caused by a dirty condenser, a malfunctioning condenser fan, or air in the system.
- If the suction pressure is high, and the evaporator and condenser are functioning normally, check the compressor amperage draw. An amperage draw near or above the nameplate rating indicates normal compressor or unit may have damaged valves. An amperage draw considerably below the nameplate rating may indicate a broken suction reed or broken connecting rod in the compressor.
DIAGNOSIS AND REPLACEMENT OF FREEZER CABINET COMPONENTS
- Defrost Time Clock
- A. Check timer motor to be sure it runs.
- B. Check contacts on the defrost timer.
- C. Check solenoid windings for continuity to ensure contact switching.
- D. Check to be sure defrost actuator pins are in proper position.
- E. Check all wires in the timer for tightness to terminals and broken wires.
- Defrost Control On The Evaporator Drain Pan
- A. If the defrost time is always 35 minutes (or whatever duration the elapsed time adjustment is set at) and the fan motors do not delay after a defrost cycle and it has been determined that the solenoid in the defrost clock is functioning, change the defrost control in the evaporator compartment in the top of the freezer. This control is attached to the evaporator drain pan.
- Coil Defrost Heater
- A. Lower the evaporator cover. Disconnect the coil heater by removing the wire nuts at the point where the heater joins the electrical circuit of the freezer in the evaporator compartment. Check heater for continuity with an ohmmeter. If the heater is defective, cut the bale wires holding the heater to the coil and remove the heater. Replace with a new heater using bale wires provided.
- Drain Tube Heater
- A. Lower the evaporator cover. Disconnect the drain tube heater by removing the wire nuts at the point where the heater joins the electrical circuit of the freezer in the evaporator compartment. Check the drain tube heater with an ohmmeter.
- B. If the drain tube heater is defective, disconnect the drain tube from the rigid plastic drain, bend the tabs that hold the evaporator drain pan to the evaporator cover and raise the drain pan so that the flexible heater is visible, pull heater out of the plastic drain tube and replace. Connect heater to the electrical circuit in the evaporator compartment.
- Cabinet Temperature Control
- A. Remove the two screws on the right side of the evaporator housing that holds the control mounting plate. Reach behind the evaporator housing on the control side of the cabinet and pull the control bulb out of the receptacle in the roof of the cabinet. Disconnect the wires from the control. Check control for continuity, replace if defective.

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 most of the 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:
- Disconnect the electrical power to the unit.
- Remove the louvered grill.
- Vacuum or brush the dirt, lint, or debris from the finned condenser coil.
- 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 replace the louvered grill. The grill protects the condenser.
- Reconnect the electrical power to the unit.

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.
- Scratches from wire brushes, scrapers, and steel pads are just a few examples of items that can be abrasive to stainless steel's surface.
- 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.
- Chlorides are present in table salt, food, and water. Household and industrial cleaners are the worst type of chlorides to use.
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 recommended strength (alkaline, 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.
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.

Warranty Information (U.S.A & CANADA ONLY!)
TRUE REFRIGERATION MADE IN U.S.A. SINCE 1945
THIS WARRANTY ONLY APPLIES TO UNITS SHIPPED FROM TRUE'S MANUFACTURING FACILITIES AFTER JANUARY 1, 2013. PRODUCT MUST BE PURCHASED IN THE COUNTRY WHERE SERVICE IS REQUESTED.
THREE YEAR PARTS & LABOR WARRANTY
TRUE warrants to the original purchaser of every new TRUE refrigerated unit, the cabinet and all parts thereof, to be free from defects in material or workmanship, under normal and proper use and maintenance service as specified by TRUE and upon proper installation and start-up in accordance with the instruction packet supplied with each TRUE unit. TRUE's obligation under this warranty is limited to a period of three (3) years from the date of original installation or 39 months after shipment date from TRUE, whichever occurs first. Any part covered under this warranty that are determined by TRUE to have been defective within three (3) years of original installation or thirty-nine (39) months after shipment date from manufacturer, whichever occurs first, is limited to the repair or replacement, including labor charges, of defective parts or assemblies. The labor warranty shall include standard straight time labor charges only and reasonable travel time, as determined by TRUE. Warranty does not cover standard wear parts which include door gaskets, incandescent bulbs or fluorescent bulbs. Warranty also does not cover issues caused by improper installation or lack of basic preventative maintenance which includes regular cleaning of condenser coils.
ADDITIONAL TWO YEAR COMPRESSOR WARRANTY
In addition to the Three (3) year warranty stated above, TRUE warrants its hermetically and semi-hermetically sealed compressor to be free from defects in both material and workmanship under normal and proper use and maintenance service for a period of two (2) additional years from the date of original installation but not to exceed five (5) years and three (3) months after shipment from the manufacturer. Compressors determined by TRUE to have been defective within this extended time period will, at TRUE's option, be either repaired or replaced with a compressor or compressor parts of similar design and capacity. The two (2) year extended compressor warranty applies only to hermetically and semi-hermetically sealed parts of the compressor and does not apply to any other parts or components, including, but not limited to: cabinet, paint finish, temperature control, refrigerant, metering device, driers, motor starting equipment, fan assembly or any other electrical component, etcetera.
404A/134A COMPRESSOR WARRANTY
The two year compressor warranty detailed above will be voided if the following procedure is not carefully adhered to:
- This system contains R404A or R134A refrigerant and polyol ester lubricant. The polyol ester lubricant has rapid moisture absorbing qualities. If long exposure to the ambient conditions occur, the lubricant must be removed and replaced with new. For oil amounts and specifications please call TRUE technical service department (800-325-6152). Failure to comply with recommended lubricant specification will void the compressor warranty.
- Drier replacement is very important and must be changed when a system is opened for servicing. A drier using XH-7 desiccant or an exact replacement solid core drier must be used. The new drier must also be the same capacity as the drier being replaced.
- Micron level vacuums must be achieved to insure low moisture levels in the system. 500 microns or lower must be obtained.
WARRANTY CLAIMS
All claims for labor or parts must be made directly through TRUE. All claims should include: model number of the unit, the serial number of the cabinet, proof of purchase, date of installation, and all pertinent information supporting the existence of the alleged defect. In case of warranty compressor, the compressor model tag must be returned to TRUE along with above listed information. Any action or breach of these warranty provisions must be commenced within one (1) year after that cause of action has occurred.
