3.3 SANITIZING
Sanitizing must be done after the machine is cleaned and
just before the hopper is fi lled with mix. Sanitizing the night
before is not effective. However, you should always clean
the machine and parts after each use.
THE UNITED STATES DEPARTMENT OF AGRI-
CULTURE AND THE FOOD AND DRUG ADMIN-
ISTRATION REQUIRE THAT ALL CLEANING AND
SANITIZING SOLUTIONS USED WITH FOOD
PROCESSING EQUIPMENT BE CERTIFIED FOR
THIS USE.
When sanitizing the machine, refer to local sanitary regu-
lations for applicable codes and recommended sanitizing
products and procedures. The frequency of sanitizing
must comply with local health regulations.
Mix sanitizer according to manufacturer’s instructions to
provide a 100 parts per million strength solution. Mix sani-
tizer in quantities of no less than 2 gallons (7.5 liters) of
90° to 110°F (32° to 43°C) water. Allow sanitizer to contact
the surfaces to be sanitized for 5 minutes. Any sanitizer
must be used only in accordance with the manufacturer’s
instructions.
In general, sanitizing may be conducted as follows:
A. Prepare Stera-Sheen Green Label Sanitizer
or equivalent according to manufacturer’s
instructions to provide a 100ppm strength solution.
Mix the sanitizer in quantities of no less than 2
gallons of 90° to 110°F (32° to 43°C) water. Any
sanitizer must be used only in accordance with
the manufacturer’s instructions.
B. Place the tapered end of the fl ow valve into the
hopper drain hole with the arm pointing towards
the left. Connect the fl ow control rod to the fl ow
valve and the fl ow valve arm (Fig. 3-3).
C. Make sure the fl ow control valve is shut by turning
the control knob counterclockwise to the 12:00

D. Place a bucket under the slide.
E. Pour the sanitizer into the hopper.
NOTE
A small amount of sanitizer may drain into the
bucket with the fl ow control shut and may seep out
of the rear seal.
F. Place the Freezing Cylinder OFF-ON switch in
the ON position and press the PURGE/CLEAN
button. The display will read PURGE.
G. Press and hold the PURGE/CLEAN button for 3

I. Clean sides of hopper, fl ow valve and underside
of hopper cover using a sanitized soft bristle brush
dipped in the sanitizing solution.
J. When the sanitizer has drained from the hopper,
press and hold the PURGE/CLEAN button for
3 seconds to stop the auger. Allow the freezing
cylinder to drain completely.
K. Shut off the fl ow control valve by turning the
fl ow control knob counterclockwise to the 12:00
position.
