STARTUP
REFRIGERATED BAKERY AND COLD DELI ONLY
A. The compressor is ready to operate. Plug in the cooler.
B. Temperature controls are factory-set to give refrigerated
bakery an approximate temperature of 38-40°F (3.3-4.4°C)
and cold deli an approximate temperature of 36-38°F (2.2-
3.3°C). Allow unit to function several hours, completely cooling
cabinet before changing the control setting.
Temperature Control Location and Settings.
• Electronic temperature control is located on rear of unit or
behind access grill.
• LAE temperature control is located on the front of cabinet
countertop or in/behind louvered grill.
• Mechanical temperature control is located outside of unit.
See website for adjustments, sequence of operation, and more
information.
C. 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.
D. 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 unit 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 ship-
ping damage has occurred. Remember, our factory warranty does not
cover product loss!

MECHANICAL TEMPERATURE CONTROLS
COIL SENSING
An evaporator coil sensing temperature control ensures that the evaporator coil will remain clear
of frost and ice by not allowing the compressor to restart until the coil temperature is above the
freezing temperature. This is considered an off cycle defrost.
MECHANICAL CONTROL DELI DISPLAY GENERAL SEQUENCE OF OPERATION
1. Cabinet is plugged in.
a. Interior lights will illuminate. If lights do not come on verify the light switch is in the “ON” position.
2. A. The compressor and evaporator fans will start on a model TCGR if the temperature control is calling for cooling.
(If the compressor does not start, verify that the temperature control is not in the “OFF” or “0” position.)
B. The compressor will start on models TSID, TDBD, and TCGG if the temperature control is calling for cooling.
(The above 3 models are a gravity style coil design and do not have an evaporator fan motor.)
3. The temperature control may cycle the compressor and evaporator fan(s) on and off together.
a. The temperature control is sensing the evaporator coil temperature.
b. The temperature control should be set on the #4 or #5.
c. The warmest setting is #1, the coldest is #9, and #0 is the off position.
d. The thermometer is designed to read and display a cabinet temperature not a product temperature.
The thermometer may reflect the refrigeration cycle swings of up and down temperatures.
The most accurate temperature on a cabinet's operation is to verify the product temperature.
4. A. There is not a defrost timer on a model TCGR as the temperature control will initiate the off-cycle defrost during each refrigeration cycle.
a. At this time, the compressor will turn off. No heaters will be energized.
b. After the evaporator coil temperature has been reached determined by the temperature control, the compressor will restart.
B. The defrost timer will initiate defrost on models TSID, TDBD, and TCGG during specific times of day.
a. At this time, the compressor will turn off. No heaters will be energized.
b. After the predetermined duration has expired, the compressor will restart

HIGH ALTITUDE APPLICATIONS
STEP 1 - Unplug cooler.
STEP 2 - Remove the screws that secure the temperature control to the inset box.
STEP 3 - To make these adjustments it may be necessary to remove the temperature control from the housing.
NOTE: You may have to remove the wires attached to the control. Take note as to which wire is on which spade terminal.
STEP 4 - Pull out gently from cabinet.
NOTE: Mechanical temperature controllers are affected when functioning at high altitude.
The cut-in and cut-out temperatures will be colder than when the controller functions closer to sea level.
STEP 5 - For high elevation installations, it may be necessary to “warm-up” the set points. To make the adjustment, insert the
appropriate tool in each adjustment screw and turn 1/4 of a revolution clockwise (to the right). This procedure will adjust both
the cut-in and cut-out about 2˚F warmer.
STEP 6 - Make sure to reconnect the wires to the proper spade terminal when reinstalling.

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 refrigera-
tion service company.
On most of the reach-in 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:
1. Disconnect the
electrical power to
the unit.
2. Remove the louvered
grill.
3. Vacuum or brush the
dirt, lint, or debris
from the finned
condenser coil.
4. 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.)
5. When finished be sure to replace the louvered grill. The grill
protects the condenser.
6. Reconnect the electrical power to the unit.
If you have any questions, please call TRUE Manufacturing at 636-
240-2400 or 800-325-6152 and ask for the Service Department.

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
