GE GFC300F - Manual (Page 5)

NOTE: Pay close attention to the order of the sink
flange parts, as they have been correctly assembled by
the factory.
A.
Disassemble the sink flange assembly from the
disposer by turning the mount ring to the left
(clockwise) and removing it.
B. Raise the mount ring toward the top of the sink
flange. Remove the cushion mount and the mount
ring. You may want to practice installing the
cushion mount at this point before you are under
the sink.
C. Unscrew the support ring from the sink flange and
remove the fiber gasket. You are now left with the
sink flange and the rubber gasket.
D. The rubber gasket is used instead of plumbers
putty with stainless steel sinks. Some cast sinks
will require putty.
E. If no putty is used, insert the sink flange through the
rubber gasket into the sink opening. Do not turn the
flange once it is seated.
F. If you use putty instead of the gasket, form a ring
around the underside of the sink flange. Insert the
flange into the sink opening, press down hard to
squeeze out excess putty. From under the sink,
trim off excess putty flush with the bottom edge of
the sink opening.
G. From underneath the sink,
slip the fiber gasket onto the
exposed sink flange. With
arrows pointing up, screw the
support ring onto the sink
flange and hand tighten until
the sink flange will not move. At this
point you may want to insert the stopper in the
sink and fill with water to check the sink flange seal
and insure there are no leaks.
H. Place the mount ring over
the sink flange and hold in
place while installing the
cushion mount (large side
down). Make sure the
groove on the inside of the
cushion mount fits over the
lip on the sink flange,
similar to putting the lid
on a plastic container.
Run your fingers
around the entire
cushion mount with
slight pressure. Do not press too hard. When the
cushion mount is properly seated, the mount ring
can be pulled downward over the cushion mount
and will be free to turn.
