CLEANING DIAPHRAGM AND FILTER
1. Turn the screw on the control stop
clockwise to turn off the water.
2. Remove the side screws from top cover
using the tamper resistant hex wrench
(provided).
3. Lift off top cover carefully, and disconnect
the solenoid harness.
4. Remove the solenoid and take out the
diaphragm. Then check the small holes
and sealing area.
NOTE: See the illustration on the right 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.
5. Check the filter to see if it is clogged with debris and gently brush it clean.
6. Reassemble in reverse order.
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 clockwise to decrease the flow rate
and turn the screw counter-clockwise to increase.
NOTE: Adjust so water amount is not excessive and
waste can flow properly.
