Filter Drier/In-line Filter
Replacement
Filter Drier/In-line Filter Removal
Remove the filter drier/in-line filter by performing
the following steps:
1. Recover the refrigerant charge from the unit.
2. Place the new filter drier near the unit for
immediate installation.
3. “Crack” both the inlet and outlet nuts on the
filter drier. Use two wrenches on flare fittings
to prevent line damage.
4. Separate the filter drier line mountings.
5. Remove the filter bracket clamping nuts and
bolts.
6. Remove the old filter drier from the unit.
Filter Drier/In-line Filter Installation
Install the filter drier/in-line filter by performing
the following steps:
1. Remove the sealing caps from the new filter
drier.
2. Apply clean compressor oil to filter drier
threads.
3. Install new filter drier in unit. Finger tighten
mounting nuts.
NOTE: To prevent incorrect installation of
the dehydrator, the inlet and outlet fittings
are different sizes.
4. Reinstall clamping brackets, nut and bolts.
Tighten the bolts.
5. Tighten filter drier inlet and outlet nuts.
NOTE: Always hold the body of the
dehydrator (or liquid filter) near the flange
fittings. This will prevent twisting the tubing
when the nuts are being loosened or
tightened.
6. Pressurize the refrigeration system and check
for leaks (see “Refrigerant Leak Test
Procedure” in this chapter). Repair leaks if
required.
7. Recover the refrigerant used for the leak test if
no leaks were found.
8. Evacuate the system (see “Evacuation and
Cleanup of the Refrigeration System” in this
chapter).
9. Recharge the unit with R-404A (see
“Charging the System with Refrigerant” in
this chapter).
10. Perform a controller pretrip test to verify
system operation.
