3. Remove the parts from the freezer door(s):
•
Gasket(s)
•
Front bearing(s)
•
Draw valve(s)
•
O-rings.
Note: To remove O-rings, use a single-service towel
to grasp the O-ring. Apply pressure in an upward
direction until the O-ring pops out of its groove. With
the other hand, push the top of the O-ring forward. It
will roll out of the groove and can be easily removed.
If there is more than one O-ring to be removed,
always remove the rear O-ring first. This will allow the
O-ring to slide over the forward rings without falling
into the open grooves.
4. Thoroughly brush clean all disassembled parts in the
cleaning solution, making sure all lubricant and mix
film is removed. Take particular care to brush clean
the draw valve core in the freezer door(s). Place all
the cleaned parts on a clean dry surface to air dry
overnight.
5. Return to the freezer with a small amount of cleaning
solution. With the black bristle brush, brush clean the
rear shell bearing(s) at the back of the freezing
cylinder(s).
