Brush Cleaning
Step 1
Prepare a sink with an approved cleaning solution
(example: Kay-5r). USE WARM WATER AND 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 c an 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: 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. With 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 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 draw valve handle and pin, ice buster ,
draw valve, front bearing and gasket from the freezer
door. R emove the 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 baf fle
assembly.
Step 4
Return to the freezer with a small amount of cleaning
solution. B rush clean the rear shell bearing at the bac k
of the freezing cylinder with the black b ristle brush.
Step 5
Remove the rear drip pan.
Note: If the drip pan is f illed with an excessive amount
of m ix, it is an indication that the drive shaft o-ring, seal
or both should b e replaced or properly lubricated.
Step 6
Thoroughly brush clean all disassembled parts in the
cleaning solution making sure all lubricant and m ix film
is removed. Place all the cleaned parts on a clean, dry
surfacetoairdry.
Step 7
Wipe clean all exterior surfaces o f the freezer.
