Leveling
Proper leveling of your TRUE cooler is critical to operating success
(for non-mobile models). Leveling impacts effective condensate
removal and door operation.
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 cabinet front). Level the cabinet.
2. Position the level at the inside rear of cabinet (again, the level
should be placed parallel to cabinet back). Level the cabinet.
3. Perform procedures similar to steps 1 and 2 by placing the
level on inside floor (left and right side, 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.
Fig. 9. Locate castor box. Back out the four screws anchoring the box.

Installation (cont.)
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.
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:
a. 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.
b. Position the level at the inside rear of the cabinet (the level
should be placed parallel to the cabinet back). Level the
cabinet.
c. 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.

Cabinet Wiring Diagram
The cabinet's wiring diagram is in the exterior servicing
compartment space of the cabinet.
A copy of the wiring diagram may also be obtained at
www. TRUEmfg.com/support/serial-number-lookup
How to Connect Electricity
• The power cord from this appliance is equipped with a
grounding plug which minimizes the possibility of electric
shock hazard.
• The wall outlet and circuit should be checked by a licensed
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.
• DO NOT, under any circumstances, cut or remove the ground
prong from the power cord. For personal safety, this appliance
must be properly grounded.
• Before your new unit is connected to a power supply, check
the incoming voltage with a voltmeter. If the recorded voltage
is less than the rated voltage for operation (+/-5%) and amp
rating, correct immediately. Refer to cabinet data plate for this
voltage requirement.
• The refrigerator/freezer should always be plugged into a
dedicated electrical circuit. This provides the best performance
and prevents building wiring circuits from being overloaded,
which could cause a fire hazard from overheated wires.
• Never unplug your refrigerator/freezer by pulling on the power
cord. Always grip plug firmly and pull straight out from the
outlet.
• When moving the refrigerator/freezer, for any reason, be careful
not to roll over or damage the power cord.
• Repair or replace immediately all power cords that have
become frayed or otherwise damaged. DO NOT use a power
cord that shows cracks or abrasion damage along its length or
at either end.
• If the supply power cord is damaged, it should be replaced with
original equipment manufacturer (OEM) components. To avoid
hazard this should be done by a licensed service provider.
NEMA Plug Configurations
60 HZ USE ONLY!
TRUE uses these types of NEMA plugs shown. If you DO NOT have
the proper outlet, have a licensed electrician verify and install the
correct power source.
International (IEC) Plugs Only
International cabinets may be supplied with a power cord that will
require installation. Install this cord before connecting the unit to a
power source.
NOTE: International plug configurations will vary by country
and voltage
Installation

original OEM plug configuration when connecting it to a power
source.
TRUE will not warranty any refrigerator/freezer that has been
connected to an adapter plug.
Use of Extension Cords
NEVER USE AN EXTENSION CORD! An extension cord is
determined to be any component that adds length to the original
OEM power cord when connecting it to a power source.
TRUE will not warranty any refrigerator/freezer that has been
connected to an extension cord.

Cabinet Operation (cont.)
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 the 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.
• An 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.

Composite Cutting Board Maintenance
Please see the message from Richlite®regarding composite cutting
boards material and preventing warping.
To prevent warping on cutting boards manufactured by
Richlite® material, simply turn the board over on a regularly
scheduled basis. Warping is caused by continued moisture and
temperature differences on the top and bottom of the boards.
By turning the board over, this will allow both sides of the
board to receive the same exposure.
There is a chance that larger sized boards may warp as a
characteristic of the material.

Maintenance, Care & Cleaning (cont.)
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 OEM (original equipment
manufacturer) 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).
