Operator’s Checklist
During Cleaning and Sanitizing
Note:
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 instead 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 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 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 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.
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
weak
of a solution will not do an
adequate job of cleaning or sanitizing.
Temperature of mix in the mix hopper and walk-in
cooler should be below 40°F (4.4°C).
Regular Maintenance Checks
Replace scraper blades that are nicked or
damaged. Before installing the beater, make sure
the scraper blades are properly attached.
Check the rear shell bearing for signs of wear
(excessive mix leakage in the driveshaft 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
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.
WARNING!
Always disconnect electrical
power prior to cleaning the condenser. Failure to follow
this instruction may result in electrocution.
If your machine is air-cooled, check the condenser
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.
For machines equipped with an air filter, it will be
necessary to vacuum-clean the filters monthly.
ALWAYS FOLLOW LOCAL HEALTH CODES.
