Operator Checklist
During Cleaning and Sanitizing
NOTICE! Cleaning and sanitizing schedules
are governed by your federal, state, or local regulatory
agencies and must be followed accordingly. Please refer
to the cleaning section of this manual for the proper
procedure to clean this machine.
IMPORTANT! Cleaning and sanitizing must be
performed daily.
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 bristle brush to clean the mix inlet hole
which 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. Use a generous amount of
cleaning solution on the brush.
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.
Using a screwdriver and cloth towel, keep the
female square drive socket and rear shell bearing
clean and free of lubricant and mix deposits.
If local health codes permit the use of rerun,
make sure the mix rerun is stored in a sanitized,
covered, NSF-approved stainless steel rerun
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.
Regular Maintenance Checks
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.
Replace scraper blades that are nicked or
damaged.
Before installing the beater, be certain that the
scraper blades are properly attached over the
beater pins.
Dispose of O-rings and seals if they are worn,
torn, or fit too loosely, and replace them with new
ones.
Follow all lubricating procedures as outlined in
“Assembly on page 6-1”.
Check the rear shell bearing for signs of wear
(excessive mix leakage in rear drip pan) and be
certain it is properly cleaned.
Check the condenser(s) for accumulation of dirt
and lint. Dirty condensers 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.
DANGER! The main power supply(s) to the
machine must be disconnected prior to performing any
installation, maintenance, or repairs. Failure to follow this
!
ALWAYS FOLLOW LOCAL HEALTH CODES.
