SEALED SYSTEM (ALL MODELS EXCEPT 601'S)

Filter-Drier (All Models except 601's)
The filter-drier is attached to to a drier bracket in the
compressor area by a cable tie.
After capturing the refrigerant from sealed system, (See
Figure 7-158):
1. Cut Cable tie.
2. With a file, score a line around capillary tube 1" or
less from drier inlet, then fatigue capillary tube at
this line until it separates.
3. With a tube-cutter, cut inlet tube 1" or less from
drier inlet.
NOTE: It is not recommended to sweat tubing apart.
Doing so will induce moisture into the sealed system.
NOTE: After capillary tube separates, check tubing for
internal burrs. If burrs exist, repeat step 2 above.
NOTE: When installing replacement filter-drier, insert
capillary tube until it touches screen inside drier, then
pull capillary tube away from screen approximately 3/8"
before brazing. (See Figure 7-159).
NOTE: Filter-drier outlet must be facing downward in
order to function properly.
Compressor (All Models except 601's)
Compressors are secured to the top of the unit with
nuts over stud-bolts. The left compressor is for the
freezer, the right is the refrigerator compressor.
NOTE: When replacing a compressor, the filter-drier
must also be replaced.
After capturing the refrigerant from sealed system, (See
Figure 7-160):
1. Remove compressor electrical cover and discon-
nect electricals from compressor.
2. Extract nuts from stud-bolts at each corner of com-
pressor base.
3. Lift compressor up and pull forward to gain access
to suction and discharge lines.
4. Using a tube cutter, cut suction and discharge lines
approximately 1" from compressor.
NOTE: It is not recommended to sweat tubing apart.
Doing so will induce moisture into the sealed system.
