C. FLUSH CYCLE
When the trip button is pressed, an electronic signal is sent
to the circuit board (which is safely housed within the pump).
This triggers a timing sequence that turns on the pump
motor for a specific length of time. The pump sends
pressurized water to the front jet and rim through the
connecting hoses. This initiates the siphon action in the
bowl, and thoroughly flushes the side walls.
As the water in the tank lowers during the pumping action,
the fill valve float drops, turning on the fill valve.
After the pump turns off, the fill valve continues sending
water to both the tank and bowl (through the refill tube). The
fill valve turns off when water reaches the proper water line
in the tank. Additionally, the water being sent through the
refill tube while the fill valve is on returns the bowl to the
proper trap seal level.
See the following safety features for flush recovery time.
