Brush Cleaning
Step 1
Prepare a sink or a pail with an approved cleaning
solution. USE WARM WATER AND FOLLOW THE
MANUFACTURER'S SPECIFICATIONS (example:
Kay-5R).
IMPORTANT: Follow the label directions. 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.
Step 2
Return to the freezer with a small amount of
cleaning solution. With a single service towel, wipe
clean the rear shell bearing surface. Brush-clean the
rear shell bearings at the back of the freezing
cylinders with the black bristle brush.

Step 3
Remove the:
Sseals and o-rings from the drive shafts
Scaps, pins, and springs from freezer doors
Sdraw valve handles from freezer doors
Sdraw valves from freezer doors
So-rings from draw valves
Sprime plugs from freezer doors
So-rings from prime plugs
Sgaskets and front bearings from freezer
doors
Sbaffle assembly, baffle arm, guide bearing,
and o-ring
Discard all o-rings and replace them with new ones.
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. W ith
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.
Step 4
Using a single-service towel, wipe the lubricant off
the parts. Brush-clean all disassembled parts in the
cleaning solution. Make sure all lubricant and syrup
is removed. Place all the cleaned parts on a clean,
dry surface to air-dry.
Step 5
Wipe clean all the exterior surfaces of the freez er.
