Sealed System
Filter-Drier Installation
Any time the sealed system is opened and the
refrigerant charge is removed, the liquid line fi lter-drier
must be replaced and the system thoroughly evacuated
before replacing refrigerant.
1. Disconnect electrical supply to refrigerator/freezer.
2. Recover refrigerant by using EPA approved
recovery system.
3. Using a 3 cornered file, score a 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 adapter to filter-drier.
9. Evacuate and charge system using the
recommended procedure described under
Evacuating and Recharging.
10. Reassemble unit.
Evaporator and Suction Line
Replacement
1. Disconnect electrical supply to refrigerator/freezer.
2. Recover refrigerant by using EPA approved
recovery system.
3. Remove shelving.
4. Remove evaporator cover.

10. Solder all connections according to soldering
procedure.
11. Remove original filter-drier.
12. Install new filter-drier at condenser outlet.
13. Evacuate and charge system using recommended
procedure described under Evacuating and
Recharging.
14. Reconnect compressor terminal leads in accordance
with unit wiring diagram.
15. Reassemble unit.
DO NOT unbraze old filter-drier from system. This
will vaporize and drive moisture from desiccant
