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:
1. Thoroughly clean and sanitize the machine
regularly including complete disassembly and
brush cleaning.
2. Use all brushes supplied for thorough
cleaning. The brushes are specially designed
to reach all mix passageways.
3. 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.
4. 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.
5. 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.
6. 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.
7. Temperature of mix in mix hopper and walk-in
cooler should be below 40 F (4.4 C).
Regular Maintenance Checks:
1. Replace scraper blades that are nicked,
damaged, or worn down. Before installing the
beater, be certain the scraper blade is
properly attached.
2. Check the rear shell bearing for signs of wear
(excessive mix leakage in drip pan) and make
certain it is properly cleaned.
3. Using a screwdriver and cloth towel, keep the
rear shell bearing and the female square drive
socket clean and free of lubricant and mix
deposits.
4. Dispose of o-rings and seals if they are worn,
torn, or fit too loosely, and replace with new.
5. Follow all lubricating procedures as outlined in
“Assembly”.
6. Check the condenser(s) for an 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 clean the filters on
a monthly schedule.
