Operator Checklist
During Cleaning and Sanitizing
NOTICE! Cleaning and sanitizing schedules
are governed by federal, state, or local regulatory
agencies, and must be followed accordingly. If the
machine 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 checkpoints should be stressed during the
cleaning and sanitizing operations.
Troubleshooting Bacterial Count
Thoroughly clean and sanitize the machine
regularly, including complete disassembly and
brush cleaning.
Use all brushes supplied for thorough cleaning.
The brushes are specially designed to reach all
mix passageways.
Use the smaller, white bristle brush to clean the
mix inlet hole that extends from the mix hopper
down to the rear of the freezing cylinder.
Use the black bristle brush to thoroughly clean the
rear shell bearing located at the rear of the
freezing cylinder. Make sure to have a generous
amount of cleaning solution on the brush.
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 the foam and
discard. Mix the rerun with fresh mix in a ratio of
50:50 during the day's operation.
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.
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.
The temperature of the mix in the mix hopper and
walk-in cooler should be below 40F (4.4C).
Regular Maintenance Checks
Check the rear shell bearing for signs of wear
(excessive mix leakage in rear drip pan) and make
sure it is properly cleaned.
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.
Dispose of O-rings or seals if they are worn, torn,
or fit too loosely, and replace with new ones.
Follow all lubricating procedures as outlined in
"Assembly" on page 6-1.
If your machine is air cooled, check the condenser
for an accumulation of dirt and lint. A dirty
condenser will reduce 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.
If your machine is equipped with an auxiliary
refrigeration system, check the auxiliary
condenser for accumulation of dirt and lint. A dirty
condenser will reduce the refrigeration capacity of
the mix hopper. Condensers must be cleaned
monthly with a soft brush. Never use
screwdrivers or other metal probes to clean
between the fins. Failure to comply may result in
electrocution.
