EVACUATING AND RECHARGING
CAUTION: Check the serial plate for the correct
refrigerant type. It is extremely important to
verify the type of refrigerant in the system
before starting any sealed system repairs.
CAUTION: With the possible exception of the
vacuum pump, all service equipment that
comes in contact with R-134a during
evacuation and recharging must be dedicated.
Accordingly, R-134a will require a dedicated
charging cylinder, manifold gauge set, process
tube adaptors, and hoses. Any residual mineral
oil on other tools (tubing cutter, etc.) must be
thoroughly cleaned off before using on R-
134a/Ester oil systems. It will be necessary to
check with the manufacturer of your vacuum
pump for refrigerant and oil compatibility
issues.
CAUTION: If you use a vacuum pump with
mineral oil to evacuate an R-134a system, it is
ABSOLUTELY ESSENTIAL to have a shut-off
valve between the pump and your manifold
gauge set as shown on page 40, Figure E2.
The hand valve must be closed during all
times when the vacuum pump is not operating.
This will prevent the migration of mineral oil
vapor into the R134a/Ester oil system. If the
vacuum pump should stop during evacuation
for any reason, the hand pump shut-off valve
must be closed immediately.
CAUTION: Insure that your refrigeration hoses
are specified for use with R-134a refrigerant.
Research has shown that compounds in stan-
dard refrigeration hoses may enter sealed
systems and ultimately restrict the cap tube
in an R-134a system.
CONDENSER REPLACEMENT
1. Disconnect electrical supply to refrigerator.
2. Remove compressor access panel.
3. Recover refrigerant by using EPA approved
recovery system.
4. Remove condenser fan mounting screws.
5. Unplug fan motor harness located in back of fan motor.
6. Remove fan motor and fan blade.
7. After refrigerant is completely recovered, disconnect
inlet and discharge lines from condenser.
8. Remove white condenser retainer clip from fan
bracket and condenser.
9. Lift front of condenser and two rubber gromments
out of retainer in base plate.
10.Move old condenser out back of cabinet.
11.Install replacement condenser.
12.Remove original filter-drier.
CAUTION: DO NOT unbraze the old filter-drier
from the system. This will vaporize and drive
moisture from the desiccant back into the
system. The old filter-drier should be cut out
of the system.
13.Install new filter-drier at condenser outlet.
14.Evacuate and charge system using procedure
described under Evacuating and Recharging on
pages 38-39.
15.Reassemble unit.
FILTER-DRIER INSTALLATION
Any time the sealed system is opened and the refriger-
ant charge is removed, the liquid line filter-drier must be
replaced and the system thoroughly evacuated before
recharging.
CAUTION: DO NOT unbraze the old filter-drier
from the system. This will vaporize and drive
moisture from the desiccant back into the
system. The old filter-drier should be cut out
of the system.
CAUTION: Use only a 15 gram XH9 liquid line
filter-drier (part number 5303305677) when
servicing refrigerator and freezer systems.
This filter-drier is compatible with either R-12
or R-134a refrigerant.
1. Disconnect unit from source of power.
2. Recover refrigerant by using an EPA approved
recovery system.
3. Use a 3 cornered file to score groove around
capillary tube as close to old filter-drier as possible.
Break capillary tube along score mark from filter-
drier.
4. Cut condenser outlet tube at filter-drier. Discard
filter-drier.
5. Thoroughly clean condenser outlet tube and
capillary tube.
6. Place inlet connection of filter-drier over condenser
tube approximately ¼” and solder.
7. Insert capillary tube input end into filter-drier outlet.
Do not allow tube to bottom against screen. Solder
carefully so that solder does not plug capillary tube.
8. Install process tube adaptor to filter-drier.
9. Evacuate and charge system using procedure
described under Evacuating and Recharging on
pages 38-39.
10. Reassemble unit.
