Remedial Cleaning Procedure
This procedure will descale the components in the water
flow path, and is used to descale the ice machine between
the bi-yearly detailed cleaning and sanitizing procedure.
Ice machine cleaner/descaler is used to remove lime scale
and mineral deposits. Ice machine sanitizer disinfects and
removes algae and slime.
NOTE: Although not required and dependent on your
installation, removing the ice machine top cover may allow
easier access.
1. Ice must not be on the evaporator during the
descaling/sanitize cycle. Follow one of the methods
below:
A. Press the power button at the end of a harvest
cycle after ice falls from the evaporator(s).
B. Press the power button and allow the ice to
melt.
,
Caution
Never use anything to force ice from the evaporator.
Damage may result
2. Open the front door to access the evaporator.
3. Press the Clean button and select “Make ice when
complete”. Water will flow through the water dump
valve and down the drain. Wait approximately 1
minute until the water trough refills and the display
indicates Add Chemical. Add the proper amount of
ice machine descaler to the water trough by pouring
between the water curtain and evaporator, then
confirm the chemical was added.
