Brush Cleaning
1. Prepare a sink with an approved cleaning solution
(examples: Kay-5
®
or Stera-Sheen
®
).
Use warm water and follow the manufacturer's
specifications.(If another approved cleaner is used,
dilute according to label instructions.)
Important! Follow label directions, since too strong
of a solution can cause parts damage, while too mild
of a solution will not provide adequate cleaning.
Make sure all brushes provided with the freezer are
available for brush cleaning.
2. Remove the O-ring and seal from the drive shaft.
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,
and 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.
3. Remove the draw valve handle and pin, ice buster,
draw valve, front bearing and gasket from the freezer
door. Remove the two O-rings from the draw valve,
and the O-ring and guide bearing from the baffle
assembly.
4. Return to the freezer with a small amount of cleaning
solution. Brush clean the rear shell bearing at the
back of the freezing cylinder with the black bristle
brush.
5. Remove the rear drip pan.
Note: If the drip pan is filled with an excessive
amount of mix, it is an indication that the drive shaft
O-ring, seal, or both should be replaced or properly
lubricated.
6. Thoroughly brush clean all disassembled parts in the
cleaning solution, making sure all lubricant and mix
film is removed. Place all the cleaned parts on a
clean, dry surface to air dry.
7. Wipe clean all exterior surfaces of the freezer.
