Section 7 Important: Operator Checklist
During Cleaning and Sanitizing:
Cleaning and sanitizing schedules are governed
by federal, state, or local regulatory agencies, and
must be followed accordingly. If the unit has a
“Standby mode”, it must not be used in lieu of
proper c leaning and sanitizing procedures and
frequencies set forth by the ruling health
authority. The following check points should be
stressed during the cleaning and sanitizing
operations.
CLEANING AND SANITIZING MUST BE
PERFORMED DAILY.
ALWAYS FOLLOW LOCAL HEALTH CODES.
Troubleshooting Bacterial Count:
j 1. Thoroughly clean and sanitize machine
regularly, including complete disassembly and
brush cleaning.
j 2. Use all brushes supplied for thorough cleaning.
The brushes are specially designed to reach a ll
mix passageways.
j 3. Use the smaller white bristle brush to clean the
mix inlet hole which extends from the mix
hopper down to the rear of the freezing cylinder .
j 4. Use the black bristle brush to t horoughly 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.
j 5. IF LOCAL HEALTH CODES P ERMIT T HE
USE OF RERUN, make sure the mix rerun is
stored in a sanitized, covered stainless steel
container and used the following day. D O NOT
prime the machine with rerun. When using
rerun, skim off the foam and discard; then m ix
the rerun with fresh mix in a ratio of 50/50during
the day’s operation.
j 6. On a designated day of the week, run the mixas
low as feasible and discard after closing. This
will break the rerun cycle and reduce the
possibility o f high bacteria counts.
j 7. Properly prepare the cleaning and sanitizing
solutions. Read and follow label directions
carefully. Too strong of a solution may damage
the parts and too weak of a solution will not do
an adequat e job of cleaning or sanitizing.
j 8. Temperature of mix in mix hopper and walk- in
cooler should be below 40_F. (4.4_C.).
Regular Maintenance Checks:
j 1. Check the rear shell bearing for signs of wear
(excessive mix leakage in rear drip pan). Verify
that it has been cleaned properly.
j 2. Using a screwdriver and cloth towel, keep the
rear shell bearing and the female hex drive
socket clean and free of lubr icant and mix
deposits.
j 3. Dispose of o- rings and seals if they are worn,
torn, or fit too loosely. Replace these o- rings
with new ones.
j 4. Follow all lubricating procedures as outlined in
“Assembly”.
j 5. Check the condenser for accumulation of dirt
and lint. A dirty c ondenser will reduce the
efficiency and capacity of the machine.
Condensers should be cleaned monthly with a
soft brush.
Note: For machines equipped with an air filter,
it will be nec essary to vacuum clean the filters
on a monthly schedule.
Never use screwdrivers or other metal
probes to clean between the fins.
