During Cleaning and Sanitizing
Cleaning and sanitizing schedules are governed by
your State or local regulatory agencies and must be
followed accordingly. The following check points
should be stressed during the cleaning and sanitizing
operations.
WE RECOMMEND DAILY CLEANING AND
SANITIZING.
ALWAYS FOLLOW LOCAL HEALTH CODES.
Troubleshooting Bacterial Count
j 1. Thoroughly clean and sanitize machine
regularly, including complete disassembly and
brush cleaning.
j 2. Use all brushes supplied for thorough cleaning.
The brushes are specially designed to reach all
mix passageways.
j 3. 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 .
j 4. Use the black b ristle 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 t he brush.
j 5. IF LOCAL HEALTH CODES PERMIT THE
USE OF RERUN, make sure the mix rerun 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. Mix the
rerun with fresh mix i n a ratio of 50/50 during the
days operation.
j 6. On a designated day of theweek, run the mix as
low as feasible and discard it after closing. This
will break the rerun cycle and reduce the
possibility of high bacteria and coliform counts.
j 7. 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.
j 8. The temperature of the mix in the mix hopper
and walk-in cooler s hould be below 40_F.
(4.4_C.).
Regular Maintenance Checks
j 1. Replace scraper blades that are n icked or
damaged. Before installing the beater
assembly, be certain that scraper blades are
properly attached to t he helix.
j 2. Check the rear shell bearing for signs of wear
(excessive mix leakage in rear drip pan) and be
certain i t is properly cleaned.
j 3. Using a screwdriver and cloth towel, keep the
rear shell bearing and the female hex drive
socket clean and free of lubricant and mix
deposits.
j 4. Dispose of o-rings and seals if they are worn,
torn, or fit too loosely, and replace with new
ones.
j 5. Follow all lubricating procedures as outlined in
“Assembly”.
j 6. If your machine is air cooled, check the
condensers 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.
Caution: Always disconnect
electrical power prior to cleaning the
condenser. Failure to follow this instruction
may result in electrocution.
