6. Chemical Cleaning Process
PM energizes to clean the water circuit with chemical solution by adjusting the rotation
speed. Then, PM de-energizes.
10 seconds: D (low speed) >> 10 seconds: A (high speed) >> 10 seconds: D (low
speed) >> 10 seconds: A (high speed) >> 10 seconds: D (low speed)
<Rinse>
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 de-energizes.
8. 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.
9. 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.
The above rinse and drain processes (8 and 9) are repeated 4 times.
<Flush>
10. Fill Process
WV opens. If F/S is closed (water in tank), the 2-minute timer starts counting down while
PM energizes. When the time is up, WV closes while PM de-energizes.
<Drain>
11. Drain Process
DV opens in 2 seconds while PM energizes and TPM starts reverse rotation 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 TPM de-energize.
If the unit had been in the halt control or water cleaning control before the fully
automated chemical cleaning control started, the halt control is resumed from the
standby process. Otherwise, the initial fill cycle starts.
