3.8 SANITIZING
Sanitizing must be done after the machine is clean and
just before the machine is fi lled with mix. Sanitizing the
night before is not effective. However, you should always
clean the machine and parts after using it.
NOTE
The United States Department of Agriculture and
the Food and Drug Administration require that all
cleaning and sanitizing solutions used with food
processing equipment be certifi ed 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 sanitizer in quanti-
ties of no less than 2 gallons of 90°F to 110°F (32°C 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.
CAUTION
Risk of Product Damage
Avoid prolonged contact of sanitizer with machine
parts. Sanitizer may cause corrosion of stainless
steel parts if there is prolonged contact.
A. Prepare 3 gallons of sanitizing solution following
manufacturer’s instructions, and pour it into the
storage container.
B. Make sure the display shows the freezing cylinder
is off. If it is not, press the On/Off Left or On/Off
Right button to turn it off.
NOTE
If the freezing cylinder is not off, the control will
