Drier
Drier is placed at post condenser loop
outlet and passes liquefied refrigerant to
capillary.
Desiccant (20) 8 x 12 4AXH - 7 M>S> -
Grams
Drier must be changed every time the system is opened for testing or
compressor replacement.
NOTE:
Drier used in R12 sealed system is not interchangeable with
drier used in R134a sealed system. Always replace drier in R134a
system with Amana part number B2150504.
Before opening refrigeration system, recover HFC134a refrigerant for safe
disposal.
1. Cut drier out of system using the following procedure. Do not unbraze drier.
2. Applying heat to remove drier will drive moisture into the system.
3. Score capillary tube close to drier and break.
4. Reform inlet tube to drier allowing enough space for large tube cutter.
5. Cut circumference of drier 31.75 mm below condenser inlet tube joint to drier.
6. Remove drier.
7. Apply heat trap paste on post condenser tubes to protect grommets from high
heat.
8. Unbraze remaining part of drier. Remove drier from system.
9. Discard drier in safe place. Do not leave drier with customer. If refrigerator is
under warranty, old drier must accompany warranty claim.
WARNING
!
To avoid death or severe personal injury, cut drier at correct location.
Cutting drier at incorrect location will allow desiccant beads to scatter. If
spilled, completely clean area of beads.
