Start-up Instructions
NOTE:
It is your responsibility to be aware
of, and conform to, the requirements for meet-
ing federal, state and local laws concerning
the frequency of cleaning and sanitizing the
freezer.
IMPORTANT:
Never let the sanitizer remain in the
freezer for more than 15 minutes.
1. Wash and sanitize your hands and
forearms.

8.1 Sanitizing
CAUTION
To prevent bacteria growth,
use only approved sanitizers
to sanitize the machine.
Sanitizing must be done just
prior to starting the machine.
Failure to do so could create a
health hazard.
The washing and sanitizing instructions
explained in this manual are important
procedures to remove bacteria and maintain
a clean, sanitary freezer. IDQ requires that
the soft serve freezer be disassembled and
washed daily according to the instructions
in the manual before sanitizing to insure the
best possible cleanliness.
IMPORTANT:
Do not use unapproved sanitizer or
laundry bleach to clean or sanitize your
freezer. These materials may contain
high concentrations of chlorine and will
chemically attack freezer components.
CAUTION
The pump will be pressurized during operation. Make sure all
components and fasteners are secure before start-up.
2. Use warm water (100° to 110°F or 38 to
43°C) to wash, rinse, and sanitize.
Prepare 4 gallons (15.2 liters) of
sanitizing solution for each cylinder.
Sanitizing solution must be mixed
according to manufacturer’s instruc-
tions to yield 100 PPM strength
chlorine solution (example: Stera-
Sheen Green Label).
3. Clean the interior mix container walls
and the underside of the container
covers with sanitizing solution and the
appropriate brush provided.
4. Insert the pickup tubes into the sanitiz-
ing solution and clean the outside
portion. If plastic mix bag systems are
used, be sure all adaptors and items
that will come in contact with mix are
sanitized.
5. Place an empty container under the
dispensing head.
6. Open the air bleed plugs by lifting up
until the plugs touch the bottom of the
switch box.
7. Reconnect the main power supplies to
the freezer. Turn the pump switch to
“ON”. This will push the sanitizer up
into the cylinders.
8. When the sanitizing solution flows out
the spigot, leave open for 2 minutes,
then close the spigots.
9. When sanitizer flows out the bottom of
the head, close the air bleed plugs.
