REFRIGERATED GRIDDLE STANDS
OPERATIONS MANUAL
EVAPORATOR ASSEMBLY
All undercounter refrigerators and freezers have an easily acces-
sible and serviceable, performance-rated, full length, extra large
coated fin coil for extended life, with a uniquely directed air flow
distribution that keeps product at uniformly constant tempera-
tures (see Figure 4).
FREEZER SYSTEM AND ADJUSTMENT
All self-contained freezers are factory set to maintain an aver-
age cabinet temperature of -4° to 0°F (-20° to -18°C). They are
designed for the purpose of holding pre-frozen product and
although they are capable of freezing small quantities of fresh
product, they are not designed to be blast chillers or ice-cream
freezers. Do not attempt to freeze bulk quantities of fresh food or
ice-cream. The temperature control is is located behind the front
grill, on the side wall of the machine compartment (see Figure
4 for thermostat location). If an adjustment is necessary to
maintain the above temperature range only, place a screwdriver
into the thermostat slot and turn clockwise for a colder cabinet
temperature or counterclockwise for a warmer cabinet tempera-
ture. Further adjustments out of the factory design temperature
range must be made by a qualified refrigeration mechanic only.
IMPORTANT NOTE: Turning a thermostat fully counter-
clockwise turns the refrigeration compressor “off.”
DEFROST OPERATION (Freezer Models)
All griddle stand freezers are equipped with an automatic, elec-
tric defrost system consisting of electric evaporator coil and
drain pan heaters, a defrost time clock and an automatic defrost
limit switch. The defrost system is time initiated by the time
clock and temperature terminated by the automatic limit switch.
The time clock is preset for (3) defrost periods per day at 8-hour
intervals with fail safe cut-off time of 20 minutes. These settings
are not adjustable. The defrost time clock is located in the front
of the machine compartment, behind the front grill. (see Figure
4). If desired, to pre-set the initiation of the defrost cycle to the
time of day on the defrost time clock, turn the knob on the center
dial of timer face clockwise until the unit defrost cycle begins
(compressor and all fans will terminate). Defrost will begin at
this same time every day at eight (8) hour intervals. For example,
if an 8:00 am defrost is desired, at 8:00 am turn the defrost
manual set knob to initiate defrost and a defrost cycle will start
every day at 8:00 am, 4:00 pm, 12:00 am. It will be necessary to
reset the time of defrost on the timer if the freezer is turned off
or has loss of power.
MAINTENANCE
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). On Griddle Stand models, the temperature control is
located behind the front grill, on the side wall of the machine
compartment (see Figure 4). If an adjustment is necessary
to maintain temperature within the range noted above, place a
screwdriver into the slotted knob on the temperature control and
turn clockwise no more than 1/4 turn for a colder cabinet tem-
perature or counterclockwise for a warmer cabinet temperature.
Allow the cabinet to stabilize for at least 30 minutes and recheck
the temperature. Further adjustments out of the factory design
temperature range should only be made by a qualified refrigera-
tion mechanic.
IMPORTANT NOTE: Turning the temperature control fully
counterclockwise turns the compressor “off.”
DEFROST OPERATION (Refrigerator Models)
All griddle stand refrigerators utilize a time initiated “off-cycle”
defrost, to ensure consistent performance, even under heavy
usage. The timer is located in the front of the machine compart-
ment, behind the front grill (see Figure 4).
If desired, the start time for a defrost cycle can be adjusted by
turning the knob on the defrost timer clockwise until defrost
cycle begins (compressor and all fans will terminate). Defrost
will begin at this same time every day at 8-hour intervals. For
example, if an 8:00 am defrost is desired, at 8:00 am turn the
timer knob to initiate defrost. A defrost cycle will start every day
at 8:00 am, 4:00 pm, 12:00 am. If there is a loss of power to the
cabinet, the defrost timer will have to be reset to maintain the
same defrost cycle times.
IMPORTANT NOTE: All refrigerators are designed with an
automatic, “off-cycle” defrost system which means that
defrosting occurs automatically when the compressor is
not operating during an off-cycle. Do not set the thermo-
stat too cold where the cabinet temperature will fall below
35°F (1.7°C) because the evaporator will become blocked
by ice since the compressor off-cycle will be considerably
shortened. This will result in loss of product stored within
the cabinet and require service to defrost the evaporator
and re-djust the thermostat.
