Brush Cleaning
Step 1
Prepare a sink with an approved cleaning solution
(example: Kay-5R). USE WARM WATER AND
FOLLOW THE MANUFACTURER’S SPECIFI-
CATIONS. If another approved cleaner is used, dilute
it according to the label instructions. (I MPORTANT:

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.

From the freezer door remove:
Sgaskets
Sfront bearings
Spivot pins

Remove all o-rings.
Note: Toremove o-rings, use a single service t owelto
graspt he o-ring. Apply pressure in an upward direct ion
until the o-ring pops out of its groov e. With the other
hand, push the top of the o-ring forward andit willroll
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 t he o-ring to slide
over the forward rings without falling into the open
grooves.
