During Cleaning and Sanitizing

Cleaning and sanitizing schedules are govern ed
by federal,state, or local regulatory agencies,
and must be followed accordin gly.If the unit
has a “Standbymode”, it must not be used in
lieu of propercleaning and sanitizing
proceduresand frequencies set forth by the
ruling healthauthority. The following check
points should be stressed during the cleaning
and sanitizingoperations.
CLEANING AND SANITIZING MUST BE
PERFORMED DAILY.
ALWAYSFOLLOW LOCAL HEALTHCODES.

Troubleshooting Bacterial Count

j1. Thoroughly clean and sanitize 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 t he white bristle brush to clean the mix inlet
hole which extends from the mix hopper down
to the rear of the freezing cylinder.
j4. Use the black bristle brus h 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 CODES PERMIT 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. Mix the
rerunwith fres h mix in a ratio of 50/50 during the
days operation.
j6. Ona designated day of the week, run the mix as
lowas f easible and discard it after closing. This
will break the rerun cycle and reduce the
possibility of high bacteria and coliform counts.
j7. Properly prepare the cleaning and sanitizing
solutions. Read and follow label directions
carefully. Toostrong of a solution m ay damage
the parts and too weak of a solution will not do
an adequate job of cleaning or sanitizing.
j8. The temperature of the mix in the mix hopper
and walk-in cooler should be below 40_F.
(4.4_C.).

Regular Maintenance Checks

j1. Replace scraper blades that are nicked or
damaged. Before installing the beater
assembly, be certain that scraper blades are
properly attached to the helix.
j2. Check the rear shell bearing for signs of wear
(excessive mix leakage in rear drip pan) and be
certain it is properly cleaned.
j3. Using a screwdriver and cloth towel, keep the
rearshell bearing and the 3/ 4hex dr ivecoupling
clean and free of lubricant and mix deposits.
j4. Dispose of o- rings and seals if they are worn,
torn, or fit too loosely, and replace with new
ones.
j5. Follow all lubricating procedures as outlined in
“Assembly”.
