REFRIGERATION SYSTEM
The major components of the refrigeration system are a reciprocating type compressor, an auxiliary
condenser, a main condenser, a condenser loop, and a spine-fin evaporator. These components,
except for the condenser loop, are all replaceable separately.
Compressor
The compressor is a reciprocating type. Refer to the Mini-Manual for the BTU/hour rating and the
compressor capacity test specification. A 1/4-inch O.D. copper process tube is provided for access to
the low pressure side of the refrigeration system.
Auxiliary Condenser
The auxiliary condenser, made of 1/4-inch O.D. copper
tubing, is connected to the compressor discharge
tube. The condenser tubing is bonded to the defrost
water pan to aid water evaporation. The outlet of the
auxiliary condenser is connected to the inlet of the
main condenser.
Main Condenser
The main condenser is made of 3/16-inch O.D. steel
tubing formed into two banks, with the tubing passes
arranged front-to-back, rather than side-to-side. The
outlet of the main condenser is connected to a copper
jumper tube that, in turn, is connected to the inlet of the
condenser loop.
Condenser Loop
The condenser loop, made of 5/32-inch O.D. copper
tubing, is foamed-in-place behind the breaker frame;
thus, not accessible for replacement. The tubing is
routed from the rear of the machine compartment
forward to the mullion, up the left side of the mullion,
across the top of the freezer compartment, across the
top of the fresh food compartment, down the right side
of the mullion, and back to the rear of the machine
compartment. The outlet of the condenser loop is
connected to the dryer inlet.
Dryer
The dryer is positioned vertically at the rear of the machine compartment. A 1/4-inch O.D. copper
process tube, connected to the inlet of the dryer, provides access to the high pressure side of the
refrigeration system. The capillary is connected to the outlet of the dryer.
Evaporator
The spine-fin evaporator, made of aluminum tubing and formed into hairpin spirals, is located below the
evaporator fan housing at the back of the freezer liner. Flanges at the top of the evaporator end-frames
are engaged into slots in the base of the fan housing that is secured to the back of the liner. To
dismount the evaporator, the fan housing must be dismounted from the liner and disengaged from the
