WORKTOPS/UNDERCOUNTERS & SANDWICH UNITS
OPERATIONS MANUAL
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.
SPECIAL VOLTAGE CONNECTIONS
When models are ordered from the factory with special, optional
voltages, connections should be made as required on the electri-
cal wiring diagram provided on the inside compressor compart-
ment rear next to the electrical console 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:
Sufficient clearance provided (see “Ventilation”)
Seperate supply with correct voltage
(see “Electrical Connections”)
Cabinet level and casters/legs tight
(see “Installation and Location”)
Doors close and seal properly (see “Door Adjustment”)
Proper cabinet temperature
(see “System and Adjustment”)
Refrigeration lines free of kinks and vibration
(see “Refrigeration System”)
Condenser and evaporator fans rotate freely
(see “Refrigeration System”)
Freezers only: Defrost clock set
(see “Freezer System and Adjustment”)
Pilaster clips secure and shelves level
(see “Shelving Installation”)
Sandwich Units: All pans and dividers in place
(see “Sandwich Top and Food Pans”)
All packaging discarded and cabinet cleaned
(see “Periodic Cleaning”)
The system should run smoothly and quietly in accordance
with generally accepted commercial standards. If any unusual
noises are heard, turn the unit off immediately and check for any
obstructions of the condenser or evaporator fans. Fan motors,
fan blades, or fan housings can be jarred out of position through
rough handling in transit or during installation.
OPERATION WITH MECHANICAL THERMOSTAT
All cabinets must be given sufficient time to reach normal
operating temperature before placing any product in cabinet.
Refrigerators are designed to maintain cabinet temperature
of 38° to 40°F (3.3° to 4.4°C), about 1 hour of operation is
required to reach this temperature. Food pans in sandwich tops
must be kept in place at all times and lids should be kept closed
whenever possible. Freezers are designed to maintain an ideal
cabinet temperature of -4° to 0°F (-20° to -18°C), about 2 hours
of operation is required to reach temperature.
THERMOMETER
Your new model has a non adjustable hanging thermometer
located inside the cabinet, mounted on the coil housing cover
(see Figure 10). This thermometer is maintenance-free and
needs no further calibration.
REFRIGERATION SYSTEM AND ADJUSTMENT
All self-contained refrigerators are designed and factory set to
maintain an average cabinet temperature of 38° to 40°F (3.3°
to 4.4°C). The temperature control is accessible inside of the
cabinet product compartment, on the right back wall next to the
evaporator coil (see Figure 11). If an adjustment is necessary
to maintain temperature within the range noted above, place a
screwdriver into the thermostat slot and turn clockwise for a
colder cabinet temperature or counterclockwise for a warmer
cabinet temperature. Further adjustments out of the factory
design temperature range should only be made by a qualified
refrigeration mechanic.
IMPORTANT NOTE: Turning a thermostat fully counter-
clockwise turns the refrigeration compressor “off.”
