[d] SANITATION CONTROL
The water circuit is periodically flushed with tap water to keep the circuit clean and
sanitary for long hours of inactivity.
The sanitation control starts:
- in sanitation mode (Setting 53), after the fill cycle or in 4 hours after the beginning of
bin control or halt control, or
- when the cleaning button is pressed in bin control or halt control.
1. Fill Process
WV opens and the 2-minute timer starts counting down. When the time is up, WV
closes. Then, the 1-minute timer starts counting down and PM energizes to flush the
water circuit with tap water. When the time is up, PM de-energizes.
2. 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.
After the end of drain process, the original process is resumed.
