( Make sure no leaking occurs.) The flush volume varies depending on the level of water. Adjust the
water level with the switch on top of the fill valve unit. Clockwise to increase the level.
Counterclockwise to decrease the level. ( Adjust only if necessary.)
3. For courtesy flush, press the manual button on the sensor unit. When the sensor senses a user in
the detection zone for 5 seconds, the sensor sends a signal to the Solenoid Valve to automatically
operate flushing after the user leaves the detection zone. Make sure the arm of the water pump doesn't
touch the tank lid when it's rising.( See the instructions on step 11) Also, make certain the remaining
manual flush handle works properly and no interference occurs among the parts inside the tank while
operating the flushing mechanism.
