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.
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:
SSeal from the drive shaft
SO--rings and guide bearing from the torque
rotor
SDraw valve from the freezer door
SO--rings from the draw valve
SGasket and front bearing from the freezer
door.
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. Wit h
the other hand, push the top of t he o--ringforward, 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.
Step 3
Remove the o--ringsfrom the inner and outer air tubes.
Step 4
Return to the freezer with a small amount of cleaning
solution. With the black bristle brush,brush clean the
rear shell bearing at the back of the freezingc ylinder.
