Section 7 Important: Operator Checklist

During Cleaning and Sanitizing:

ALWAYS FOLLOW LOCAL HEALTH CODES.
Cleaning and sanitizing sched ules are governed
by federal, state, or local regulat ory agencies, and
must be followed accord ingly. If the unit has a
“Standby mode”, it must not be used in lieu of
proper cleaning and sanitizing p rocedures and
frequencies set forth by the ruling health
authority. The following checkpoints should be
stressed during the cleaning and sanitizi ng
operations.
CLEANING AND SANITIZING MUST BE
PERFORMED DAILY.

Troubleshooting Bacterial Count:

j1. Thoroughly clean and sanitize machine
regularly, including complete disassembly and
brush cleaning.
j2. Useall brushes supplied f or thorough cleaning.
The brushes are specially designed to reach all
mix passageways.
j3. Usethe white bristle brush t o clean the mix feed
tube, which extends from the hopper down 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 CODES PERMIT THE
USE OF RERUN, make sure the mix rerun is
stored in a sanitized, covered stainless s teel
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. Ona designated day of the week, run the mix as
low as feasible and discard 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 s olution may damage
the parts and too weak of a solution will not do
an adequate job of cleaning or sanitizing.
j8. Temperature of mix in mix hopper and walk -in
cooler should be below 40_F. (4 .4_C.).

Regular Maintenance Checks:

j1. Replace scraper blades that are nicked,
damaged or worn down. Before installing
beater, be certain the scraper blade is properly
attached.
j2. Check rear shell bearing for signs of wear
(excessive mix leakage in drip pan) and be
certain it is properly cleaned.
j3. Using a screwdriver and cloth t owel, keep the
rear shell bearing and the female square drive
socket 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.
j5. Follow all lubricating proc eduresas outlined in
“Assembly”.
j6. Checkthe condenser(s) for accum ulation of dirt
and lint. Dirty condensers will r educe the
efficiency and capacity of the machine.
Condensers should be cleaned monthly with a
soft brush. Never use screwdrivers or other
metal probes to clean between the fins.
Note: For machines equipped with an air filter,
it will be necessary to vacuum clean the filters
on a monthly schedule.
