Cabinet Location

1. Ensure that the drain hose or hoses are positioned in the pan.
2. Free the plug and cord from inside the lower rear of the cooler (DO NOT plug in).
3. Place the unit close enough to the electrical supply so that the extension cords are never used.

Leveling Leg, 6″ Leveling Leg, or Castor Installation
Leveling legs are provided to assist with leveling the cabinet. Adjustable legs provide 6″ (152 mm) of clearance under the cabinet. Castors provide cabinet mobility.

NOTE:
If the cabinet has a center leveling screw, castor, or leg, make sure it is adjusted properly so it makes full contact with the floor after the cabinet has been leveled.

Required Tools
Required tools include (but may not be limited to) the following:

• Adjustable Wrench

Procedure — Leveling Legs
With access to the bottom of the cabinet, thread the leveling legs into the holes used to secure the cabinet to the skid. See figs. 1 and 2.

Procedure — 6″ (152 mm) Leveling Legs

1. Access the bottom of the cabinet and thread the leveling legs into the rail. See figs. 3 and 4.
2. Verify that the cabinet is level.
3. If the cabinet is not level, gently lift and support the low end of the cabinet. With an adjustable wrench, screw the bottom stem of the leveling leg in or out to level and support the cabinet. See fig. 5.

Procedure — Castors

1. Loosen the castor bolt enough to slide the provided castor shims between the castor bearing and the bottom rail of the cabinet. See Fig. 6.
2. Install the desired number of shims. If more than one shim is used, turn the slots at a 90˚ angle to each other, so the slots do not align. See figs. 7 and 8.
3. Tighten and secure the shims and castors with the optional castor wrench. Lower the cabinet and verify that it is level. If the cabinet is not level, repeat the process until the cabinet is level and supported.

Leveling
Proper leveling of your TRUE cooler is critical to operating success (for non- mobile models). Leveling impacts effective condensate removal and door operation.

Procedure
Level the unit front-to-back and side-to-side.

1. Position the level on the inside floor of the unit near the doors (the level should be parallel to the cabinet front). Level the cabinet.
2. Position the level at the inside rear of the cabinet (again, the level should be placed parallel to the cabinet back). Level the cabinet.
3. Perform procedures similar to steps 1 and 2 by placing the level on the inside floor (left and right sides, parallel to the depth of the cooler). Level the cabinet.

NOTE:
If the cabinet has a center leveling screw, castor, or leg, make sure it is adjusted properly so it makes full contact with the floor after the cabinet has been leveled.

Sealing the Cabinet to the Floor
Asphalt floors are susceptible to chemical attack. A layer of tape may be placed on the floor prior to applying the sealant to protect the floor.

Procedure

1. Position the cabinet, allowing 3″ (73 mm) between the wall and the rear of the cabinet to ensure proper ventilation.
2. Level the cabinet. The cabinet should be level side-to-side and front-to-back. To check that the cabinet is level, place a carpenter’s level on the interior cabinet floor in four places:
   • Position the level on the inside floor of the cabinet, near the doors (the level should be placed parallel to the cabinet front). Level the cabinet.
   • Position the level at the inside rear of the cabinet (the level should be placed parallel to the cabinet back). Level the cabinet.
   • Perform procedures similar to a. and b. by placing the level on the left and right inside floor (level should be parallel to the cabinet sides). Level the cabinet.
3. Draw an outline of the cooler base on the floor.
4. Raise and block the front side of the cabinet.
5. Apply a bead of NSF-approved sealant (see list below) to the floor, 1/2″ (13 mm) inside the front part of the outline drawn in step 4. The bead of sealant must be heavy enough to seal the entire cabinet surface when the cabinet is lowered on top of the sealant.
6. Raise and block the rear of the cabinet.
7. Apply sealant to the floor on the other three sides, as outlined in step 5.
8. Examine the cabinet to ensure that it is sealed to the floor around the entire perimeter.

2. With the larger strip opening on the bottom, snap the flavor strip onto the shelf. See figs. 2-3.
3. Install tags into the flavor strip. See Fig. 4.

Cabinet Operation

Startup

• The compressor is ready to operate when the unit is purchased. All you need to do is plug in the cooler.
• Excessive tampering with the control could lead to service difficulties. If replacing the temperature control is ever needed, be sure to order the replacement from your TRUE dealer or recommended service agent.
• Good airflow inside your TRUE unit is critical. Take care to prevent the product from pressing against the sides or back wall and coming within 4″ (101.6 mm) of the evaporator housing. Refrigerated air off the evaporator coil must circulate throughout the cabinet for even product temperatures.

NOTE: If the unit is disconnected or shut off, wait 5 minutes before restarting.

RECOMMENDATION
Before loading the product, run your TRUE unit empty for 24 hours to verify proper operation. Remember, our factory warranty DOES NOT cover product loss!

Temperature Control & Light Switch Location

• The light symbol shows the approximate location of the light switch.
• The electronic temperature control can act as a light switch. To control the light, press the up arrow .

FOR MORE INFORMATION
For more information regarding a cabinet’s temperature control adjustment or general sequence of operation, please see our Temperature Control Adjustment—Sequence of Operation Manual in our resource library at https://www.truemfg.com/Service-Manuals/Sequence-of-Operation or follow the QR code.

General Sequence of Operation — Refrigerator and Freezer Cabinets

When the cabinet is plugged in

• Interior lights will illuminate on glass door models (see previous page for light switch location).

• An electronic control with digital display will illuminate (if installed).

• There may be a short delay before the compressor and/or evaporator fan(s) start. This delay may be determined by time or by temperature, which could be the result of an initial defrost event that will last at least 6 minutes.

• The temperature control/thermostat may cycle the compressor and evaporator fan(s) on and off together. Every cabinet will require a defrost event to ensure the evaporator coil remains clear of frost and ice buildup. Defrost is initiated by a defrost timer or by electronic control.
  EXCEPTION – Models TSID, TDBD, TCGG, and TMW do not have an evaporator fan(s).

• The temperature control/thermostat senses either an evaporator coil temperature or air temperature, NOT product temperature.

• An analog thermometer, digital thermometer, or electronic control display may reflect the refrigeration cycle swings of up and down temperatures, NOT product temperature. The most accurate method to determine a cabinet’s operation is to verify the product temperature.

• Refrigerators with mechanical temperature controls will defrost during every compressor off-cycle.

• Freezers with mechanical temperature controls will defrost by time initiation as determined by a defrost timer.
  EXCEPTION – Models TFM, TDC, THDC and TMW require a manual defrost. The frequency of this manual defrost will depend on the cabinet’s usage and ambient conditions.

• Electronic control with a digital display (if installed) will show dEF during defrost.
  NOTE: The display may have a short delay before showing a temperature after a defrost event has expired and instead show dEF during a refrigeration cycle.

• Models with an analog or digital thermometer may show higher than normal temperatures during defrost.

• A refrigerator will use the evaporator fans to clear the coil during defrost.
  EXCEPTION – Models TSID, TDBD, and TCGG do not have an evaporator fan(s).

• A freezer will use heaters to clear the evaporator coil during defrost.
  NOTE: The evaporator coil heater and drain tube heater are only energized during defrost. Defrost is terminated when a specific evaporator coil temperature is reached or by a time duration.

Maintenance, Care & Cleaning

CAUTION!
Take care during operation, maintenance or repairs to avoid cuts or pinching from any cabinet part/component.

Condenser Coil Cleaning
When using electrical appliances, basic safety precautions should be followed, including the following:

• WARNING! – Electrical shock or burn hazard. Unplug the unit or turn off the power supply before proceeding. DO NOT clean appliance with a pressure washer or hose.

4. With dirt removed from the surface of the coil, use a flashlight to verify that you can see through the coil and observe the condenser fan blade. See fig. 5.
   NOTE: If your view is blocked, gently blow compressed air or CO2 through the coil until it is clean.

5. Carefully vacuum any dirt around the condensing unit area.

6. Reinstall the louvered grill, connect power to the unit, and verify operation.

Important Warranty Information

THE CLEANING OF THE CONDENSER IS NOT COVERED BY WARRANTY!
If you have any questions, please contact your local TRUE Manufacturing Service Department. See the front cover for locations and contact information.

• Condenser coils accumulate dirt and require cleaning every 30 days or as needed.
• A dirty condenser coil can result in non-warranted repairs and/or cabinet failure.
• Proper cleaning involves removing dust from the condenser by using a soft brush, vacuuming the condenser with a shop vac, or using CO₂, nitrogen or pressurized air.
• Do not place any filter material in front of the condensing coil.
• On most units, the condenser is accessible by removing the cabinet’s outer grill cover.
• If you cannot remove the dirt adequately, please contact your licensed refrigeration service provider.

Stainless Steel Care & 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 form.

• Scratches from wire brushes, scrapers, steel pads, and other 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 which are present in table salt, food and water, as well as in household and industrial cleaners. These are the worst type of chlorides to use on stainless steel.

Stainless Steel Cleaning and Restoration
DO NOT use stainless steel cleaners or similar solvents to clean plastic or powder-coated parts. Instead, use warm soapy water.

• For routine cleaning and removal of grease and oil, apply white vinegar, ammonia, or any good commercial detergent* with a soft cloth or sponge.
• Stainless steel polish (e.g., Zep® Stainless Steel Polish, Weiman® Stainless Steel Cleaner & Polish, Nyco® Stainless Steel Cleaner & Polish, or Ecolab® Ecoshine®) and olive oil can act as a barrier against fingerprints and smears.
• Degreasers* (e.g., Easy-Off® Specialty Kitchen Degreaser or Simple Green® Industrial Cleaner & Degreaser) are excellent for removal of grease, fatty acids, blood and burnt-on foods on all surfaces.
  • DO NOT use detergents or degreasers with chlorides or phosphates.
• For restoration/passivation or removing stubborn stains and discoloration, Brillo® Cameo®, Zud® Cleanser, Ecolab® Specifax™ First Impression® Metal Polish, Sheila Shine, or talc can be applied by rubbing in the direction of the polish lines.

NOTE:
The use of proprietary names is intended for example only and does not constitute or imply an endorsement. Omission of proprietary cleansers from this list does not imply inadequacy.

8 Tips to Help Prevent Rust on Stainless Steel

Maintain the Cleanliness of Your Equipment
Avoid build-up of hard stains by cleaning frequently. Use cleaners at the recommended strength (alkaline chlorinated or non-chloride).

Use 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.

Clean Along Polishing Lines
Polishing lines (“grain”) are visible on some stainless steels. Always scrub parallel to polishing lines when visible. Use a plastic scouring pad or soft cloth when you cannot see the grain.

Use Alkaline, Alkaline-Chlorinated or Non-Chloride 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.

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.

Never Use Hydrochloric Acid (Muriatic Acid) on Stainless Steel
Even diluted, hydrochloric acid can cause corrosion, pitting and stress corrosion cracking of stainless steel.

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

Regularly Restore & Passivate Stainless Steel
Stainless steel gets its stainless properties from the protective chromium oxides on its surface. If these oxides are removed by scouring, or by reaction with harmful chemicals, then the iron in the steel is exposed and can begin to oxidize, or rust. Passivation is a chemical process that removes free iron and other contaminants from the surface of stainless steel, allowing the protective chromium oxides to re-form.

Cabinet Adjustments, Servicing, & Component Replacement

NOTE: Any cabinet adjustments are to be made AFTER the cabinet has been verified level and properly supported.

Servicing & Replacing Components

• Replace component parts with original equipment manufacturer (OEM) components.
• Have a licensed service provider service your unit to minimize the risk of possible ignition due to incorrect parts or improper service and to ensure the operator’s health and safety.
• Unplug the refrigerator/freezer before cleaning or making any repairs. Setting temperature controls to the 0 position or powering off an electronic control may not remove power from all components (e.g., light circuits, perimeter heaters, and evaporator fans).

Warranty Information

(USA & Canada Only)

FIVE-YEAR HYDROCARBON PARTS & LABOR WARRANTY & THREE YEARS HFC 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 five (5) years for hydrocarbon (HC) units and three (3) years for HFC units from the date of the original installation. Any warranty coverage is dependent on the purchase date of the cabinet being within 39 months of the original ship date from TRUE. Any part covered under this warranty that is determined by TRUE to have been defective within this time frame, 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 HYDROCARBON COMPRESSOR WARRANTY
In addition to the five (5) year warranty stated above, TRUE warrants its hermetically and semi-hermetically sealed Hydrocarbon (HC) 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, part only for compressor defects only. Our HFC compressors will have the three (3) years parts & labor detailed above and an additional two (2) years for a compressor part only for compressor defects warranty.

Compressors determined by TRUE to have been defective within this time period will, at TRUE’s option, be either repaired or replaced with a compressor or compressor parts of similar design and capacity. The compressor component 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/HYDROCARBON COMPRESSOR WARRANTY
The compressor warranty detailed above will be voided if the following procedure is not carefully adhered to:

1. This system contains R404A, R134A, or R290 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 (855-372-1368). Failure to comply with recommended lubricant specification will void the compressor warranty.
2. Drier replacement is very important and must be changed when a system is opened for servicing. An OEM exact replacement should be used. The new drier must also be the same capacity as the drier being replaced.
3. Micron level vacuums must be achieved to ensure 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 the 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, a picture of the compressor model tag must be returned to TRUE along with the above-listed information. For warranty claim information, visit www.truemfg. com/Support/Warranty-Support. Any action for breach of these warranty provisions must be commenced within three (3) months of the defect giving rise to the breach.

True reserves the right to request any failed part covered under warranty to be returned.
