Refrigerator High-Side Filter-Drier Removal
(Model ICB427R Only)
To remove the high-side filter-drier it may help to slide
the unit tray out slightly, then
1. Evacuating refrigerant from sealed system.
2. With a tube-cutter, cut filter-drier inlet.
5. At filter drier outlet, use a file to score a line around
the capillary tubes, 25 mm (1'') or less from the out-
let, then fatigue the capillary tube at this line until
they separates.
NOTE: After capillary tube separates, check tubing for
internal burrs. If burrs exist, repeat step above.
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, rescore 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 9.5 mm (3/8")
away from the screen before brazing
When installing a new filter-drier, be sure to thoroughly
clean the tubing before brazing.
