Operator Checklist
During Cleaning and Sanitizing
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 feed
tube which extends from the hopper up 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 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.
 
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 solution may not do an
adequate job of cleaning or sanitizing.
 
The temperature of the mix in the mix hopper and
walk-in cooler should be below 40°F (4.4°C).
Regular Maintenance Checks
 
Rotate the scraper blades to allow both sides of
the knife edge to wear evenly. This will contribute
to self-sharpening and help maintain fast, efficient
freezing.
 
Replace scraper blades that are bent, damaged,
or worn down.
 
Before installing the beater, make sure the scraper
blades are properly attached over the beater pins.
 
Dispose of O-rings and seals that are worn, torn,
or fit too loosely, and replace them.
 
Check the rear shell bearing for signs of wear
(excessive mix leakage in rear drip pan) and
make sure it is properly cleaned.
 
Using a screwdriver and cloth towel, keep the
female drive socket and the rear shell bearing free
of lubricant and mix deposits.
 
Follow all lubricating procedures as outlined in
“Assembly” on page 6-1.
 
On air-cooled machines, check the condenser for
an accumulation of dirt and lint. Dirty condensers
will reduce the efficiency and capacity of the
machine. The condensers should be cleaned
monthly . Remove the side panels to gain access
to the condensers. Use a soft brush to clean
between the fins of the condenser. 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 on a
monthly schedule.
 
On water-cooled machines, check the water lines
for kinks or leaks. Kinks can occur when the
machine is moved back and forth for cleaning or
maintenance purposes. Deteriorated or cracked
water lines should be replaced only by an
authorized Taylor technician.

ALWAYS FOLLOW LOCAL HEALTH CODES.
