
THEORY OF OPERATION
The mechanical refrigeration system uses a 1/2 horsepower low temperature
compressor and capillary tube system controlled by a temperature control to
provide cooling to copper coils mounted around the stainless steel cavity.
Operate freezer by turning it “ON” or “OFF” with the master switch, not with
the thermostat.
IMPORTANT: When loading freezer, DO NOT load above product load
line for proper operation and product temperature. This equipment is
intended for use with pre-packaged foods only.
Product should be in a frozen state when placed in the freezer. If product is
soft, place lids on unit to aid in temperature pull-down.
IMPORTANT: Once the serving period is completed, place lids back onto
freezer. Leave lids on until the next serving period. DO NOT leave lids
off longer than 2 hours at one time.
