Installation (cont.)
Leveling
Proper leveling of your TRUE cooler is critical to operating success
(for non-mobile models). Leveling impacts effective condensate
removal and door operation.
Procedure
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.
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.
Procedure
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.

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.

Cabinet Operation
Startup
• The compressor is ready to operate when the unit is purchased.
All you need to do is plug in the cooler.
• Excessive tampering with the control could lead to service
difficulties. If replacing the temperature control is ever needed,
be sure to order the replacement from your TRUE dealer or
recommended service agent.
• Good air flow inside your TRUE unit is critical. Take care to
prevent product from pressing against the sides or back
wall and coming within 4" (101.6 mm) of the evaporator
housing. Refrigerated air off the evaporator coil must circulate
throughout the cabinet for even product temperatures.
NOTE: If the unit is disconnected or shut off, wait 5 minutes
before restarting.
RECOMMENDATION – Before loading product, run your TRUE
unit empty for 24 hours to verify proper operation. Remember,
our factory warranty DOES NOT cover product loss!
Temperature Control & Light Switch Location
The switch is located on the front of the evaporator housing

Cabinet Operation (cont.)
General Sequence of Operation — 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.
Cabinet Operation (cont.)
Pressure
Dispensing pressures differ based on the following:
• Draft dispensing line length.
• Draft dispensing system type.
• Actual product (pressure requirements vary).
• Product temperature.
• Pressurizing agent: Air pressure, CO₂ or special blended gases.
Helpful Hints on Maintaining the Correct Pressure
• Know which pressurizing agent to use on which product, and
why.
• Monitor your regulators to ensure applied pressure remains
constant.
• Keep equipment in good repair.
Tapping
DO NOT agitate the kegs unnecessarily. If excessive agitation
occurs, allow kegs to settle 1 to 2 hours before tapping.
Prior to tapping the keg, ensure all beer faucets in the serving
location are in the off position. Completely remove the dust cover
(identification cap) from the keg.
DRAFT BEER SHOULD BE TREATED AS A FOOD PRODUCT.
In most instances draft beer is not pasteurized. It is very
important that you store and handle it properly.
Follow these steps to ensure the highest quality and consumer
satisfaction.
• Immediately store draft beer in a refrigerated cabinet.
• Draft beer products have a recommended shelf life. If you have
questions regarding the shelf life of any of your draft products,
please consult with your supplying depot or respective brewer
representative.
• Store kegs separately from food products. If your cooler is used
to refrigerate draft and food products, DO NOT store food near
or on the kegs.
• Keep keg storage and dispensing areas clean to prevent any
possibility of contaminating your draft products.
Temperature
Correct temperature is a key factor in storing and dispensing draft
beer. Beer that is too cool or too warm may be subject to flavor
loss, off taste and dispensing problems.
Helpful Hints for Controlling Temperature
• Keep a thermometer handy.
• Monitor the draft temperature in the cooler and at the tap.
• Keep cooler door closed as much as possible to avoid
temperature fluctuation.
• Regular maintenance of refrigeration equipment is
recommended.
