Important: Operator Checklist
During Cleaning and Sanitizing
ALWAYS FOLLOW LOCAL HEALTH CODES.
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 cleaning 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.
Troubleshooting Bacterial Count
j
1. Thoroughly clean and sanitize the machine
regularly, including complete disassembly and
brush cleaning.
j
2. Use all brushes supplied for thorough cleaning.
The brushes are specially designed to reach all
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 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.
j
5. IF LOCAL HEALTH CODES PERMIT THE
USE OF RERUN, make sure the mix rerun is
stored in a sanitized, covered stainless steel
container and is used the following day. DO
NOT prime the machine with rerun. When using
rerun, skim off the foam and discard. Mix the
rerun with fresh mix in a ratio of 50/50 during the
day’s operation.
j
6. On a 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.
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 adequate job of cleaning or sanitizing.
j
8. The temperature of the mix in the 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) and be
certain it is properly cleaned.
j
2. Using a screwdriver and cloth towel, keep the
rear shell bearing and the female hex drive
socket clean and free of lubricant and mix
deposits.
j
3. Dispose of o- rings or seals if they are worn,
torn, or fit too loosely, and replace with new
ones.
j
4. Follow all lubricating procedures as outlined in
“Assembly”.
