Cleaning Instructions
CAUTION
Electric shock hazard. Do not splash water on the control panel orallow
waterto flow onto electrical components inside the machine.
CAUTION
To prevent bacteria growth, remove all o-rings when cleaning. Failure
to do so could create a health hazard.
1. Prepare a three-compartment sink
for washing, rinsing, and sanitizing parts
removed from the freezer, per applicable
health codes. Also, prepare a clean surface
to air-dry all parts.
Important:
Do not use unapproved sanitizer or
laundry bleach. These materials may
contain high concentrations of chlorine
bleach and will chemically attack freezer
components.
NOTE:
The sanitizer should be mixed
according to the manufacturer’s instructions
to yield 100 parts per million (PPM) available
chlorine solution. (example: Stera Sheen

or 38 to 43°C) to wash, rinse, and sanitize.
Make sure the sanitizer is mixed thoroughly
and has completely dissolved.

freezer thoroughly with a warm, mild dish
detergent solution. Clean the following parts
with the appropriate supplied brush:
a. The mix feed tube, regulator main
bore and cross holes (figure 8-5).

center plunger ports, breaker bar cavities, o-
ring grooves, dispense nozzle mounting rings
