Section 7

During Cleaning and Sanitizing

ALWAYS FOLLOW LOCAL HEALTH CODES.
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.
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 white bristle brush to clean the mix feed
tube, which extends from the hopper down to the
rear of the freezing cylinder.
 Use the black bristle brush to thoroughly clean the
rear shell bearing at the rear of the freezing
cylinder. Use a generous amount of cleaning
solution on the brush.
 If local health codes permit the use of rerun,
make sure it is stored in a sanitized, covered
stainless-steel container and used the following
day. Do not prime the machine with rerun. When
using rerun, skim off the foam and discard, then
add fresh mix in a ratio of 50:50 during the day's
operation.
Operator Checklist
Operator Checklist
 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.
 Temperature of mix in mix hopper and walk-in
cooler should be below 40°F (4.4°C).

Regular Maintenance Checks

Replace scraper blades that are nicked,

damaged, or worn down. Before installing the
beater, make sure the scraper blades are properly
attached.
 Check rear shell bearing for signs of wear
(excessive mix leakage in drip pan) and make
sure it is properly cleaned.
 Using a screwdriver and cloth towel, clean the
rear shell bearing and the female square drive
socket of lubricant and mix deposits.
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 condenser(s) for 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 monthly.
