WARNING
Wear rubber gloves and safety goggles (and/or face shield)
when handling ice machine cleaner / descaler or sanitizer.
Cleaner / Descaler (9405463)
and Sanitizer (9405653)
Usage
Important
Ice machine cleaner /descaler is
used to remove lime scale and
mineral deposits. Ice machine
cleaner / descaler should
be used every six months,
although in cases of extremely
hard water conditions it may
be necessary to descale more
often. For the range of water
hardness allowed for potable
water standards, it should not
be necessary to descale more
frequently than every two
months. Use of an approved
filtration system with a
polyphosphate scale inhibitor
is highly recommended for all
ice machine installations and
will significantly reduce the
need to descale in hard water
applications.
Ice machine sanitizer disinfects
and removes algae and slime.
Sanitizer must be used a
minimum of once every six
months.
,
CAUTION
Do not immerse the water
pump motor or electrical
connector in liquids. Only
soak the water pump
impeller and impeller
housing. Do not immerse
above the red line on the
graphic.
Notice
Electrical connectors must never be exposed to any
liquids.
15. Remove scale deposits
from removed parts.
Mix 16 oz Manitowoc ice
machine cleaner / descaler
(9405463) with one gallon of
potable water in a three-
compartment sink.
Place the plastic parts in the
solution and allow to soak
for 10-15 minutes. Use a
soft bristle brush on heavy
scale or mineral buildup as
required.
16. Clean scale deposits
from surface areas of
ice machine.
Use a clean towel or sponge
soaked in cleaner / descaler
solution to wipe ice machine
surfaces, including the sides
walls, base (area above
water trough), and the bin
or dispenser.
17. Rinse Surface Areas of
Ice Machine.
Use a clean towel or sponge
soaked in potable water to
wipe ice machine surfaces,
including the sides walls,
base (area above water
trough), and the bin or
dispenser.
,
CAUTION
Do not soak the water pump
motor in rinse water or
sanitizer solution. Be sure
to only rinse/soak the water
pump impeller and impeller
housing. Do not immerse
above the red line on the
graphic.
Notice
Electrical connectors must never be exposed to any
liquids.
