Maintenance Section 4
Remedial De‑scaling Procedure
This procedure de‑scales all components
in the water flow path, and is used to
de‑scale the ice machine between the
bi‑yearly detailed de‑scaling and sanitizing
procedure.
Ice machine de‑scaler 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.
Step 1 Ice must not be on the evaporator
during the de‑scale/sanitize cycle. Follow
one of the methods below:
• Press the power switch at the end of
a harvest cycle after ice falls from the
evaporator(s).
• Press the power switch and allow the ice
to melt.
Notice
Never use anything to force ice from the
evaporator. Damage may result.
Step 2 Open the front panel to access
the evaporator.
Step 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 de‑scaler to
the water trough by pouring between the
water curtain and evaporator, then confirm
the chemical was added.
