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.

Electrical Installation & Safety
Use of Adapter Plugs
NEVER USE AN ADAPTER PLUG! An adapter plug alters the
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.
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
Fully seat the power cord into the cabinet receptacle until it locks
in position. See fig. 1.
Removal
Depress the red button. See fig. 2.
Fig. 1.
Fully insert the power cord into
the receptacle.

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.
