Brush Cleaning
Step 1
Prepare a sink with an approved cleaning solution
(example: Kay-5r). USE WARM WATERAND FOL-
LOW 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 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.
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.
Step 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.
Step 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.
Step 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, dr y
surfacetoairdry.
Step 7
Wipe clean all exterior surfaces of the freezer.
