START UP
After having correctly installed the ice maker and
completed the plumbing and electrical
connections, perform the following “Start-up” pro-
cedure.
A.
Switch ON the power line disconnect switch
and push the green button switch. Unit will start
up in charging cycle mode.
NOTE. Every time the unit returns under
power, after having been switched off, the
water inlet valve, the hot gas valve and the
water drain valve get energized for a period
of 5 minutes, thus to admit new water to the
machine sump reservoir to fill it up and,
eventually, to wash-off any dirt that can have
deposited in it during the unit off period
(Fig.1).
B.
During the water filling operation, check to
see that the incoming water dribbles, through the
evaporator platen dribbler holes, down into the
OPERATING INSTRUCTIONS
sump reservoir to fill it up and also that the
incoming surplus of water flows out through the
overflow pipe into the drain line.
During the water filling phase the components
energized are:
THE WATER INLET SOLENOID VALVE
THE HOT GAS SOLENOID VALVE
THE WATER DRAIN SOLENOID VALVE (Not
on AC 106).
NOTE. If in the 5 minutes lenght of the water
filling phase the machine sump reservoir
does not get filled with water up to the rim of
the overflow pipe, it is advisable to check:
1.The water pressure of the water supply line
that must be at least 1 bar (14 psig) Minimum
(Max 5 bar-70 psig).
2.The filtering device installed in the water
line that may reduce the water pressure
below the Minimum value of 1 bar (14 psig).
3. Any clogging situation in the water circuit
like the inlet water strainer and/or the flow
control.
