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.
If the machine has a STANDBY mode, it must not be
used instead 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.
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 with the machine for
thorough cleaning. The brushes are specially
designed to reach all mix passageways.
Use the long 38 in. (97 cm) white bristle brush to
clean the mix feed tube which extends from the
mix reservoir 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.
If the 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 off the foam
and discard, then 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 the label directions
carefully. Too
strong
of a solution may damage
the parts, and too
mild
of a solution will not do an
adequate job of cleaning or sanitizing. Sanitize the
freezing cylinder for 5 minutes.
The temperature of the mix in the mix cabinet and
the walk-in cooler should be below 40°F (4.4°C).
Regular Maintenance Checks
Replace scraper blades that are bent, damaged,
or worn.
Before installing the beater, make sure that the
scraper blades are properly attached over the pins
and the beater assembly is straight.
Check the rear-shell bearing for signs of wear
(excessive mix leakage in the rear drip pan) and
make sure it is properly cleaned.
Using a screwdriver and cloth towel, clean the
rear-shell bearing and the female hex drive socket
free of lubricant and mix deposits.
Dispose of O-rings and 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
condensers 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.
FOLLOW YOUR LOCAL ELECTRICAL CODES.
