tank with chemical solution before the time is up. Then, wait until the timer expires or
press the cleaning button.
3. Fill Process
PM energizes. In 3 seconds:
- if F/S is open (no water in tank), it is supposed that chemical solution has not been fed
manually. Then, the fill process starts.
- if F/S is closed (water in tank), it is supposed that chemical solution has been fed
manually. Then, the cleaning process starts.
WV opens. If F/S is closed (water in tank), PM de-energizes and the 2-minute timer
starts counting down. When the time is up, WV closes.
4. Chemical Cleaning Process
PM energizes to clean the water circuit with chemical solution by adjusting the rotation
speed. Then, PM de-energizes.
10 seconds: A (high speed) >> 10 seconds: D (low speed) >> 10 seconds: A (high
speed) >> 10 seconds: D (low speed) >> 10 seconds: A (high speed)
<Drain>
5. 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.
<Rinse>
6. Rinse 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 rinse the water circuit with tap water. When the time
is up, WV closes and PM de-energizes.
7. 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 and every component de-energize. The rinse counter counts "+1".
The above rinse and drain processes (6 and 7) are repeated until the rinse counter
counts "+4".
If the unit had been in the halt control before the automated chemical cleaning control
started, the halt control is resumed from the standby process. Otherwise, the initial fill
cycle starts.
