GENERAL OPERATIONS
PRINCIPLES OF OPERATION
13
All the dipping cabinet models are of the same basic
design, consisting of a bare tube condenser and a cap
tube fed tank wrap evaporator.
Ice formation on the walls over a period of time is
normal. This frost should be scraped off periodically in
order to maintain peak performance. These cabinets
are thermostatically controlled for various temperature
requirements. The thermostat is located post adjacent
to the unit compartment and can be accessed for
adjustment by the user with a screwdriver or a dime.
Thermostat position #1 being the warmest and
position #7 the coldest.
These cabinets are manual defrost and a drain is
provided for periodic cleaning. A garden hose can be
attached to the drain plug for draining away any water
that might have accumulated. This drain attachment is
located in the front base rail of the cabinet. NOTE: The
power supply cord must be disconnected when
cleaning or servicing these cabinets.
NOTE: On initial cabinet pull down the bare tube
condenser may become warm to the touch until
the normal operating temperatures are achieved.
Refer to model serial data tag for cabinet amperage,
refrigerant charge & type.
Compressors being used in these cabinets utilize
refrigerant 404A and polyol ester oil. Because of the
hygroscopic nature of this oil, extreme care must be
taken when any component is changed within the
system. In the case of compressor replacement, work
should be completed before the caps are removed
from the compressor.
Agitation of the oil should be kept to a minimum.
Compressors should not be open to the atmosphere
for more than 15 minutes max. Should contamination
occur the oil can be removed and recharged (following
compressor manufacturer's guidelines when
performing this procedure). Because of the porous
nature of plastic, polyol ester oil should be stored in a
metal container. Moisture contained within the oil
cannot be removed even under high vacuum
conditions and must be replaced.
