B. The unit should be leveled front to back and side to side with a level.
C. Free plug and cord from the top of the unit (do not plug in).
D. The unit should be placed close enough to the electrical supply so that extension cords are never used.
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.
WARNING: WARRANTIES ARE VOID IF THE UNIT IS MORE THAN 7 FT. (2.1M) FROM PLUG-IN CONNECTION.
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:
A. Position level in the inside floor of the unit near the doors. (Level should be parallel to cabinet front). Level cabinet.
B. Position level at the inside rear of cabinet. (Again level should be placed parallel to cabinet back).
C. 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 outlined 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.

2. Start at the bottom in terms of shelf installation and work your way up.
3. Always lay the back of each shelf down on the rear clips before the front.

Type Kit #1 (Angle Type Tray Slide)

Type Kit #2 (Rod Style Tray Slide)

Type Kit #3 (Universal Tray Slide)
CONFIGURATION (PILASTERS):
Each TRUE Specification Series (STR, STA, and STG) is available with two pilaster configurations. Each configuration depends on the end user preference. Multiple door units can have two configurations for each section. See image 7.
INSTALLATION PROCEDURES (PILASTERS):
Install slotted thumb screws into threaded holes along the inside wall of the cabinet.
Slide pilasters into position behind the slotted screws. Leave all of the thumb screws loose for adjustments when installing tray slides.
It is critical to measure from the center of the square hole on the front pilaster to the center hole of the rear pilaster. This measurement should be 24 5/8″ (625 mm) (see image 8). Do the same on the opposite side of cabinet for single door. Make sure the measurement of 24 5/8″ (625 mm) is the same in the center pilasters in 2 and 3 door units. Tap the tray slides into the Pilasters with a rubber Mallet. Angle & Rod Type shelving uses a 18 1/8″ (460 mm) distance between Pilasters. Universal Tray slides have a 21 1/4″ (540 mm) distance between Pilasters. See image 9.
After the pilasters are installed the Universal Tray, Angle Type Tray, and Rod Style Tray Slides will slide into the pilasters. See images 1-6. When disassembling or changing tray slides a rubber mallet may be used to take out the different tray slides. Gently tap on the udder of the tray slide to loosen it from the pilaster.

  LAE MODEL HEATED CABINET ELECTRONIC CONTROL GENERAL SEQUENCE OF OPERATION

  1. Cabinet is plugged in.
     a. Display will illuminate.

  2. The LAE control will energize the heat elements if the control is calling for heat.

  3. The LAE control will cycle the heating elements on and off determined by the Set-Point and Differential temperatures.
     a. The Set-Point is the adjustable preprogrammed temperature which de- energizes the heat elements. 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 re-energize the heat elements.
     c. The LAE control is designed to read and display a cabinet temperature not a product temperature. This cabinet temperature may reflect the heating cycle of the Set-Point and it’s Differential. The most accurate temperature on a cabinets operation is to verify the product temperature.

Example: If the Set-Point is 180°F/82.2°C and the Differential is 1°F/.56°C (Set-Point) 180°F + 1 (Differential) = 181°F
Or
(Set-Point) 82.2°C + .56 (Differential) = 82.76°C The heating elements will cycle on 180°F/82.2°C and back off at 181°F/82.76°C

MAINTENANCE, CARE, CLEANING

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

WARRANTY INFORMATION (U.S.A. & CANADA ONLY!)
THIS WARRANTY ONLY APPLIES TO UNITS SHIPPED FROM TRUE’S MANUFACTURING FACILITIES AFTER SEPTEMBER 1, 2015.
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/HYDROCARBON COMPRESSOR WARRANTY
The two year 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 insure low moisture levels in the system. 500 microns or lower must be obtained.
