Brush Cleaning
Step 1
Prepare a sink with an approved cleaning solution
(examples:Kay- 5Ror Stera - SheenR). USE WARM
WATER AND FOLLOW THE MANUFACTURER’S
SPECIFICATIONS. (If another approved cleaner is
used, dilute according to label instructions.)
IMPORTANT: Follow label directions, as 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
Remove the o- ring and seal from the drive shaft.
Note: Toremove 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 and
it will roll out of the groove and can be easily removed.
If there is more than one o- ring tobe remov ed, 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 3
Remove the draw valve handle and pin, ice buster,
draw valve, front bearing and gasket from the freezer
door.Remove t he scraper blade clips from the scraper
blades. Remove the two o- rings from the draw valve,
and the o- ring and guide bearing from the baffle
assembly.

solution. Brush clean the rear shell bearing at theback
of the freezing cylinder with the black bristle brush.

ofmix , it isan indicat iont hat the drive shaft o- ring, seal
