Brush-Cleaning
1. Prepare a sink with a cleaning/sanitizing solution with
an active chlorine concentrate of 100 to 200 ppm.
(examples: Kay-5
®
or Stera-Sheen
®
). Use warm
water and follow the manufacturer's specifications.
(If another approved cleaner is used, dilute according
to label instructions.)
Important!
Follow the label directions. 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.
2. Remove the O-ring and seal from the driveshaft.
Remove the O-ring and the bearing from the torque
rotor.
3. Remove the draw handle, draw valve, ice buster,
front bearing, prime plug, freezer door, and gasket
from the freezer door. Remove the spring and prime
plug (self-closing door only). Remove all O-rings.
Note:
To remove an O-ring, use a single-service
towel to grasp the O-ring. Apply pressure upward
until the O-ring pops out of its groove. With the other
hand, push the top of the O-ring forward until it rolls
out of the groove and can be easily removed.
4. 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, dry surface to air-dry.
5. 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.

6. Wipe clean all exterior surfaces of the freezer.
