3.9 SANITIZING
Sanitizing must be done after the freezer is clean and just
before the freezer is filled with mix. Sanitizing the night
before is not effective. However, you should always clean
the freezer and parts after using it.

the Food and Drug Administration require that
all cleaning and sanitizing solutions used with
food processing equipment be certified for this
use.
When sanitizing the freezer, refer to local sanitary regula-
tions for applicable codes and recommended sanitizing
products and procedures. The frequency of sanitizing must
comply with local health regulations. Mix sanitizer ac-
cording to manufacturer’s instructions to provide a 100
parts per million strength solution. Mix sanitizer in quan-
tities of no less than 2 gallons of 90°F to 110°F 90° 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 in-
structions.
CAUTION
