Section 7 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 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 there is 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, NSF approved
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; then 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. Rotate scraper blades to allow both sides of the
knife edge to wear evenly. This will contribute to
self-sharpening and help maintain fast, efficient
freezing.
j 2. Replace scraper blades that are nicked,
damaged or worn.
j 3. Before installing the beater, be certain that
scraper blades are properly attached over the
pins.
j 4. Check the rear shell bearing for signs of wear
(excessive mix leakage in rear drip pan) and be
certain it is properly cleaned.
j 5. 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.
