CLEANING AND SANITIZING MUST BE
PERFORMED DAILY.

Troubleshooting Bacterial Count

j1. Thoroughly c lean and sanitize the machine
regularly, including complete disassembly and
brush cleaning.
j2. Use all brushes s upplied for thorough
cleaning. The brushes are specially designed
to reach all mix passageways.
j3. Use the whit e bristle brush to clean the mix
feed tube which extends from the hopper up
to the rear of the freezing cylinder.
j4. Use the black bristle brush to thoroughly
clean the rear shell bearing located at the rear
of the freezing cylinder. Be sure to have a
generous amount of cleaning solution on the
brush.
j5. IF LOCAL HEALTH CODE SP ERMIT THE
USE OF RERUN, make sure the mix rerun is
stored in a sanitized, covered stainless steel
container and used the following day. DO
NOT prime the machine with rerun. When
using rerun, skim off the foam and discard,
then mix the rerun with fresh mix in a ratio of
50/50 during the day's operation.
j6. Properly pr epare the cleaning and sanitizing
solutions. Read and follow label directions
carefully. Too strong of a solution may
damage the parts and too weak of solution
may not do an adequate job of cleaning or
sanitizing.

and walk-in cooler should be below 40_F.
(4.4_C.).

of the knife edge to wear evenly. This will
contribute to self-sharpening and help
maintainfast, efficient freezing.

damaged, or worn down.
j3. Before ins talling the beater, be certain that the
scraper blades are properly attached over the
beater pins, and into the blade clip.
