5.8 FILTER DRIER
The filter drier must be replaced every time the refrigeration
system is opened for service. A new filter drier improves
operation of the entire refrigeration system by stopping the
circulation of moisture and by removing harmful contami-
nants (Refer to Figure 5-12).
FILTER DRIER REMOVAL
A. Recover refrigerant charge per instructions in
Section 5.2.
B. Cut the refrigeration line as close to the filter drier
as possible and remove drier.
C. Cap the ends of the drier using the plugs from the
new drier.
NOTE
The drier must be capped to prevent moisture from
the environment
FILTER DRIER REPLACEMENT
A. Position the filter drier so the arrow is pointing
toward the direction of refrigerant flow (pointing
away from the condenser).
B. Apply a heat sink (wet cloth) to the filter drier.
C. With the suction and discharge ports open, braze
the filter drier into the system.
D. Evacuate the system per instructions in Section
5.2.
E. Recharge the system per instructions in Section
5.3.
