Maintenance/Cleaning/Adjust
Disassembly Cleaning / Sanitizing - This procedure
should be performed by a qualified service technician
only, as it entails disassembly of the ice machine for a
more thorough cleaning and sanitizing.
1. Perform an in place cleaning as described on page
4-3. The clean cycle takes about 30 minutes.
When the clean cycle is complete, disconnect
power to the unit and switch off water supply.
DISCONNECT ELECTRIC POWER TO THE ICE
MACHINE BEFORE PROCEEDING.
2. Mix 16oz (473 ml) of undiluted ice machine cleaner
(7013400 only) with 2 gallons (7.6 liters) of warm
water.
NOTE: Since this mixture will be divided into two
equal batches, halving the ingredients mentioned
above and mixing them in two separate vessels
may be helpful.
WEAR RUBBER GLOVES AND SAFETY GOGGLES
(AND/OR FACE SHIELD) WHEN HANDLING ICE
MACHINE CLEANER OR SANITIZER.
Do not mix Cleaner and Sanitizer solutions togeth-
er. It is a violation of Federal law to use these solu-
tions in a manner inconsistent with their labeling.
3. After removing all parts as described in Removal of
Parts for Cleaning and Sanitizing, take components
to a sink for cleaning. Use 1/2 of the cleaner/water
mixture to clean all components. The cleaner solu-
tion will foam when it contacts lime scale and min-
eral deposits; once the foaming stops, use a soft-
bristle nylon brush, sponge or cloth (NOT a wire
brush) to carefully clean the parts. Disassemble
the spray bar, remove nozzles and inserts and soak
for 5 minutes. For heavily scaled parts, soak in
solution for 15 – 20 minutes. Rinse all components
with clean water.
Do not immerse the water pump motor in the clean-
ing or sanitizing solution.
4. While components are soaking, use the other 1/2 of
the cleaner/water solution and a nylon brush or
cloth to clean inside of ice bin. Clean inside of
door, door gasket, bin, top of evaporator and evap-
orator bucket. Rinse all areas thoroughly with clean
water.

erally apply the solution to all surfaces of the
removed parts or soak the removed parts in the
sanitizer/solution. Rinsing is not required.
