WARNING!DANGER!

RISK OF CHILD
ENTRAPMENT

PROPER DISPOSAL OF THE REFRIGERATOR

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.

APPLIANCE DISPOSAL

When recycling appliance please make sure that the refrigerants are
handled according to local and national codes, requirements and
regulations.

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 war-

ranty any refrigerator that has been connected to an extension cord.

REPLACEMENT PARTS

• Component parts shall be replaced with like components.

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.

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.

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.

NORTH AMERICA USE ONLY!

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.

a. Control or condenser fans may be already pre-programmed from the factory so at the star t 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.

3. 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.
a. The Set-Point is the adjustable preprogrammed temperature which shuts off the compressor and evaporator fan(s).

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 restar t the compressor and evaporator fan(s).

c. The LAE control is designed to read and display a cabinet temperature not a product temperature.

This cabinet temperature may reflect the refrigeration cycle of the Set-Point and it’s Differential.
The most accurate temperature on a cabinets operation is to verify the product temperature.

* STA, STG, STM, STR Models.

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

4. The L AE control may be preprogrammed to initiate defrost by interval or at specif ic times of day.

a. 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. Some cabinets may also change the rotation of the reversing condenser
fan motor.

b. Af ter 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.

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 ser vice
expense and lower your electrical costs. The Condenser requires
scheduled cleaning every thir ty 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 the Spec Series units the condenser is accessible on the top of
the unit. You must lift open the cabinet rainshield 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 rainshield.

3. Vacuum or brush the dirt, lint, or debris from the finned
condenser coil.

4. If you have a significant dir t build up you can blow out the
condenser with compressed air.

(CAUTION MUST BE USED TO AVOID EYE INJURY.
EYE PROTECTION IS RECOMMENDED.)

5. When f inished be sure to close the rainshield.

6. Reconnect the electrical power to the unit.

If you have any questions, please call TRUE Manufacturing at 636-240­2400 or 800-325-6152 and ask for the Service Depar tment. Direct

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 sof t water depending on what part of the country you live
in. Har d water can leave spot s. 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. Benef it, 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 f ilters 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.

23

7. HYDROCHLORIC ACID (MURIATIC ACID)

SHOULD NEVER BE USED ON STAINLESS STEEL

8. REGULARLY RESTORE/PASSIVATE STAINLESS
