GFI/GFCI RECEPTACLES
Ground-Fault Circuit Interrupter (GFCI or GFI) devices are not
recommended for most commercial refrigerators and freezers,
since nuisance trips may occur, typically due to moisture. This
can cause temporary loss of power, which may result in high
storage temperatures and potentially unsafe food product.
Building codes in some areas may require certain 115 volt
receptacles to be protected by a GFI. If you need to connect your
equipment to a protected circuit, a properly sized, commercial
grade GFI circuit breaker should be used on a separate, isolated
power supply. Or a qualified electrician may be able to hard wire
your equipment, eliminating the need for a GFI device. Contact
Continental’s Service Department before making any modifica-
tions to your cabinet, to avoid loss of warranty.
NOTE: GFI RECEPTACLES ARE NOT RECOMMENDED,
PRODUCT LOSS OR SERVICE PROBLEMS RESULTING
FROM NUISANCE TRIPS, CONNECTION TO A DEFECTIVE
OR IMPROPER POWER SUPPLY, AND UNAUTHORIZED
MODIFICATIONS TO YOUR EQUIPMENT CAN CAUSE A
HAZARD AND WILL VOID FACTORY WARRANTY.
115 VOLT, 60 HZ, 1 PHASE CONNECTION
All 115 volt models are provided with a factory
installed, UL approved 15-amp power cord and
NEMA 5-15P plug, or a 20-amp power cord and
NEMA 5-20P plug. To insure proper operation,
this equipment must be plugged into a NEMA
compatible, grounded receptacle that can sup-
ply the full voltage and amperage stated on the
serial plate (see Figure 1).
IMPORTANT NOTE: A SEPARATE, ISOLATED, PROPERLY
SIZED POWER SUPPLY MUST BE PROVIDED. GFCI
DEVICES AND/OR EXTENSION CORDS SHOULD NOT
BE USED. PRODUCT LOSS, AS WELL AS PROBLEMS
RESULTING FROM NUISANCE TRIPS OR HIGH/LOW
VOLTAGE, ARE NOT COVERED UNDER WARRANTY.
CAUTION: IF UNIT IS UNPLUGGED OR DISCONNECTED
FOR ANY REASON, ALLOW 5-6 MINUTES BEFORE
TURNING THE UNIT BACK ON TO ALLOW THE SYSTEM
TO EQUALIZE. DISREGARDING THIS PROCEDURE
COULD CAUSE AN OVERLOAD AND PREVENT THE UNIT
FROM OPERATING.
115/208-230 VOLT, 60 HZ, 1 PHASE CONNECTION
All 115/208-230 volt models are provided with three (3) sup-
ply wires, which exit the electrical box located in the machine
compartment rear, next to the compressor. The cabinet circuitry
is 115 volts and the condensing unit operates on 208-230 volts.
A permanently connected, 3-wire (plus ground) power supply is
required, consisting of (2) hot conductors and (1) neutral wire,
plus (1) ground wire. The supply leads must be connected to
the appropriate leads from the cabinet and the supply ground
wire must be attached to the electrical box with a ground lug
to provide proper grounding of the metal cabinet and chassis.
All wiring and connections should only be made by a qualified
electrician and must conform to all local electrical codes.
SPECIAL VOLTAGE CONNECTIONS
When models are ordered from the factory with special voltages,
connections should be made as required on the electrical wiring
diagram provided next to the electrical control box.
START-UP CHECKLIST
After your unit has been installed and electrically connected in
accordance with this manual, please take time to check the fol-
lowing before loading product, to assure trouble-free operation:
q Sufficient clearance and ventilation provided around
cabinet (see “Ventilation”)
q Unit connected to separate power supply at correct
voltage (see “Electrical Connections”)
q Cabinet is level and casters/legs are tight
(see “Installation and Location”)
q Doors close and seal properly
(see “Door Removal and Adjustment”)
q Cabinet operating at correct temperature
(see “System and Adjustment”)
q Thermometer properly calibrated
(see “Thermometer and Calibration”)
q Condensate vaporizer installed correctly
(see “Condensate Removal”)
q All refrigeration lines free of kinks and excess vibration
(see “Refrigeration System”)
q Condenser and evaporator fans rotate freely
(see “Refrigeration System”)
q Freezers only: defrost time clock set correctly
(see “Freezer System and Adjustment”)
q All pilaster clips installed securely and shelves are level
(see “Shelving Installation”)
q All packing materials discarded and cabinet properly
cleaned (see “Periodic Cleaning”)
