High-Side Filter-Drier Removal
(All Tall Units)
The high-side filter-driers are located in the center of
the unit tray, behind the condenser and are attached to
the drier bracket with a cable tie.
NOTE:
Before attempting to remove a filter drier, evac-
uate the refrigerant from the sealed system.
To access and remove a high-side filter-drier, the kick-
plate/grille will need to be removed first and the unit
tray will need to be slid out. To slide the unit tray out,
extract the two screws that secure the tray to the unit,
located at the front right and left corners. Grab the front
flange of the tray and pull forward.
NOTE:
It may be necessary to disconnect the com-
pressor electrical leads in order to pull the tray out far
enough to access the filter-driers.
Begin removing the filter-drier by cutting the cable tie
which secures the filter-driers to the drier bracket. With
the edge of a file, score a line around the capillary tube
approximately one inch from the filter-drier outlet, then
fatigue the capillary tube at this line until it separates.
With a tube cutter, cut the inlet tube approximately one
inch from the filter-drier.
NOTE:
Sweating the joints apart is not recommended
as this may induce moisture into the sealed system and
could cause a solder restriction in the capillary tube.
NOTE:
Check the end of the remaining capillary tube
for internal burrs. If burrs exist, re-score a line around
the capillary tube (approximately one inch from the end)
and fatigue the capillary tube at this new line until it
separates.
NOTE:
When installing the replacement filter-drier,
insert the capillary tube until it touches the screen, then
pull the capillary tube approximately 3/8” away from the
screen before brazing.
When
installing a new filter-drier, be sure to thoroughly clean
the tubing before brazing.
