GENERAL INFORMATION
Introduction
The information contained in this manual pertains to
Zero Zone 2- and 3-door self-contained freezers
used for frozen food or ice cream merchandising.
Zero Zone has made every effort to produce
refrigeration equipment of the highest quality using
state of the art components and modern
manufacturing techniques.
Read these instructions carefully and completely
before attempting to install Zero Zone equipment.
Refer to all National, State, and local electrical,
health and HVACR code requirements before
installation.
These display freezers are designed to operate in
an air-conditioned environment where the air
temperature is maintained at 75°F or lower and the
relative humidity does not exceed 55%.
Inspection
These display freezers were factory-tested,
inspected and properly packed to ensure delivery in
the best possible condition. This equipment should
be checked for damage immediately upon delivery,
both before and after. ALL CLAIMS FOR DAMAGES
MUST BE FILED WITH THE TRANSPORTATION
COMPANY – NOT WITH ZERO ZONE. The carrier
will supply necessary report and claim forms.
Location
The freezer must not be installed in the direct rays of
the sun or near a source of radiant heat. It must be
installed on a sound floor of sufficient strength and
must be level and plumb for proper operation.
A minimum 4” space between the back of the
freezer and the building wall or shelving must be
maintained for proper airflow.
INSTALLATION
Electrical
The freezer lights, fans, and door heaters operate
on 115 volt, 1 phase, 60 Hz. The compressor and
defrost heater operate on 208/230 volt, 1 phase, 60
Hz.
All internal wiring has been completed at the
factory. The 115-208/230 volt power connections
are made to the leads protruding from the left side
of the electrical box, which is located on the right
side of the compressor compartment.
A cord connection is optional on the 2-door case.
When a cord is supplied, a NEMA 14-20R four prong
20 amp twist lock receptacle must be provided in
your store. The cord length is approximately 6 feet.
A four-wire 115-208/230 volt single-phase circuit is
required for both case sizes. Wiring should be sized
according to the amperage rating stamped on the
serial plate. A standard 2-door case is rated at 20
amps. A standard 3-door case is rated at 25 amps.
Note: all wiring must comply with the National
Electrical Code and all local codes.
Start-up
Make sure the compressor floats free on the
mounting grommet. The case is shipped with the
valves back seated (open).
Energizing the electric circuit will start the case. On
cord-connected units, the on/off switch must be
switched on after the cord is connected. The on/off
switch is mounted on the electric box located in the
front of the case behind the grill. After the case is in
operation, set the Time Clock to the proper time of
day so that defrost will occur at the desired time.
To set the Time Clock, remove the front grill and
locate the display on the face of the electrical box.
Flip up the plastic bezel face of the display to reveal
four keypad buttons.
