your State or local regulatory agencies and must be
followed accordingly. The following check points
should be stressed during the cleaning and sanitizing
operations. CLEANING AND SANITIZING MUST BE
PERFORMED EVERY 14 DAYS.

Troubleshooting Bacterial Count

j1. Thoroughly clean and sanitize machine

brush cleaning.
j2. Useall brushes supplied for thor oughcleaning.
The brushes are specially designed to reach all
mix passageways.
j3. Usethe white bristle brush to clean the mix inlet
hole which extends from the mix hopper down
to the rear of the freezing cylinder.
j4. Use the black bristle brush to thoroughly clean
the rear shell bearing located at the rear of the
freezing cylinder and the drive hub opening in
the rear wall of the mix hopper. Be sure to have
a generous amount of cleaning solution on the
brush.

solutions. Read and follow label directions
carefully. Toostrong of a s olution may damage
the parts and too weak of a solution will not do
an adequate job of cleaning or sanitizing.

air filters for accumulation of dirt and lint . Dirty
condensers or air filters will reduce the
efficiency and capacity of the machine.
Condensers and filters should be cleaned
monthly. The air filters can be removed from
therear of the f reezer and brought to the s ink for
cleaning. Usea soft brush to clean between the
fins of the condensers. Never use screwdrivers
or other metal probes to clean between thefins.
j9. Onwater cooled units, check thewater 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 mechanic.
