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 from this appliance is equipped with a grounding plug which
minimizes the possibility of electric shock hazard.
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 it’s 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.
If supply power cord is damaged it should be replaced with original equipment
manufacture parts. To avoid hazard this should be done by a qualified service
technician.

LOCATING
-
Make sure unit is as close to the final location as possible.
-
Remove the shipping bolts located at the bottom of the wooden skid.
-
Carefully slide the unit off the wooden skid. Slide packing material underneath the side of the unit hanging off the skid.
Then install castors or legs for that side of the unit. -
Then carefully slide the other side of the unit off one corner at a time while installing castors or legs for each corner. Use packing material for under each corner of the unit before installing a castor or leg.
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 handtightened securely
against the lower rail assembly.
The bearing race on the castor or the top edge of the leg must make firm
contact with the rail.
LEVELING SHIMS
Four leveling shims have been provided for leveling castored units positioned
on uneven floors. Shims must be positioned between rail end and bearing race.
A. Turn the bearing race counter-clockwise until the cabinet is level. Level
front to back and side to side. (diagonally)
B. Install the desired number of shims, making sure the slot of the shim is in
contact with the threaded stem of the castor.
C. If more than one shim is used, turn the slot at a 90° angle so they are not
in line.
D. Turn the bearing race clockwise to tighten and secure the castor by
tightening the anchoring bolt with a 3/4 inch openend wrench or the tool
provided.
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.
LEVELING
A. Proper leveling of your TRUE unit is critical to operating success (for
non-mobile models). Effective door operation will be effected by leveling.
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.
NSF APPROVED SEALANTS:
- Minnesota Mining #ECU800 Caulk
- Minnesota Mining #ECU2185 Caulk
- Minnesota Mining #ECU1055 Bead
- Minnesota Mining #ECU1202 Bead
- Armstrong Cork – Rubber Caulk
- Products Research Co. #5000 Rubber Caulk
- G.E. Silicone Sealer

ROLL-IN & ROLL-THRU RAMP INSTALLATION
Once the cabinet is in its final location and level the roll-in ramp can be
installed. The ramp has three slotted holes in back. These slotted holes slide
over three thumb screws located in the front of the cabinet near the floor.
DOOR SWEEP GASKET ADJUSTMENT
To adjust door sweeper gasket, loosen slotted thumbscrews. The gasket can then
be moved up or down and side to side. The gasket should make some contact with
the ramp when the door is closing.
This can be checked by opening up the door 3-4″ and allowing the door to
close. This process may have to be done several times before securing the
sweeper gasket bracket. Once gasket is properly adjusted, tighten slotted
thumbscrews. See image 5.
HUMIDIFICATION PROCEDURE
ADJUSTING HUMIDITY
This instruction is TRUE’s recommended procedure for providing interior
humidity control.
The heated cabinet is designed to provide flexibility in desired interior

SHELF INSTALLATION TIPS
- Install all the shelf clips before installing the shelves.
- Start at the bottom in terms of shelf installation and work your way up.
- Always lay the back of each shelf down on the rear clips before the front.
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.

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.
-
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.
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:
-
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
GENERAL MAINTENANCE
RAINSHIELD
When using electrical appliances, basic safety precautions should be followed,
including the following:
CAUTION: BEFORE PERFORMING SERVICE OR MAINTENANCE MAKE SURE RAINSHIELD IS
SECURED IN OPEN POSITION. USE INSTRUCTIONS
AND PHOTOS BELOW TO SECURE RAINSHIELD.
- Remove thumbscrews on the top of each cabinet end.
- Lift rainshield (careful not to pull on any wires)
- Reinstall thumbscrews
A. The thumbscrews should be put through rainshield holes and fastened into previous position in cabinet end.
CAUTION: MAKE SURE TOP RAINSHIELD IS CORRECTLY SEATED IN THE OPEN POSITION.
