CLEANING DIAPHRAGM AND FILTER
1. Turn the screw on the control stop
clockwise to turn off the water.
2. Disconnect the solenoid.
3. Remove the solenoid and take out the
diaphragm. Then check the small holes
and sealing area.
NOTE: See below for disassembly.
NOTE: Do not stretch or alter the shape of
the spring in the solenoid valve in
any way. It will void the warranty.
CHECKING THE SOLENOID
1. Make sure the batteries are properly placed and cables are connected.
2. With water supply turned off, place your hand in front of the sensor for 6 seconds.
3. Remove and listen for a "click" sound after 3 seconds. This indicates the solenoid
plunger has been activated.
BATTERY REPLACEMENT
A special lithium back-up battery is used. Replace
only with the battery provided by TOTO.
If a red light in the sensor window blinks with the
cycle of 4 seconds, it is time to replace the
battery.
1. Remove the old battery.
2. Set the new battery at the proper position.
ADJUSTMENT OF THE FLOW RATE
1. Adjust the flow rate by the turning screw on the control stop.
2. Turn the screw to the right to decrease the flow rate and turn to the left to increase.
