[e] WATER CLEANING CONTROL
The water circuit is flushed with tap water at the set frequency, while adjusting the PM
flow rate, to prevent scaling of the circuit.
The water cleaning control starts:
- automatically at the set frequency of water cleaning counter (Setting 44), or
- when the cleaning button is pressed other than in bin or halt control.
1. Drain Process
DV opens in 2 seconds while PM energizes to drain the water tank. If F/S is open (no
water in tank), the drain timer starts counting down. When the time is up, DV closes
while PM de-energizes.
2. Fill Process
WV opens. If F/S is closed (water in tank), the 2-minute timer starts counting down while
PM energizes to supply water and flush the water circuit with tap water. When the time
is up, WV closes and PM de-energizes.
3. Water Cleaning Process
PM energizes in 2 seconds to flush the water circuit with tap water by adjusting the
rotation speed. Then, PM de-energizes.
