INSTALLATION DIMENSIONSINSTALLATION DIMENSIONS
Notice:
a. The dimensions above are just for reference.
b. The connection take between the outlet connection and urinal is not supplied in this package.
c. To ensure an effective flush performance, an urial with corresponding flush volume is required.
Siphon urinal is not recommened
Recommended working water pressure: 0.18MPa.~0.55MPa.
0.18MPa-0.55MPa
INSTALLATIONINSTALLATION
1. Determine the installation location per rough-in
dimensions and the table of installation position.
Chisel out a slot and install the supply tubes.Then
flush the supply tubes. The depth of the slot is not
less than 90mm, see the figure to the right for
rough in dimension requirement. See the figure
right for rough-in dimension requirement.
Notice:
a. No light shall enter or be reflected into the
sensing window.
b. No reflectible objects in front of the sensing
window (e.g., mirror, polishing stainless steel and
some other polished plates).
c. No strong ultraviolet radiation or electromagnetic
field nearby.

2. First, connected the Connecting Pipe to the pipeline,
then to connect with the mortar inlet end and
Connecting Pipe. Connecting the outlet-side by
mounting dimensions of the urinal (see page 3)
Note:
a. Do not mistake the direction out of the water.
b. Please put the rubber gasket into the middle of
connection with water inlet and movable joint,
then tighten the nut activities
a.The AC 220V power line enclose the electrical wire
tube, and inserted ti into the tube hole.
b. Remove the protective cover, 2 red lines on the
adapter, respectively, to tied together with the
2 AC 220V power wires, then use electrical tape to
wrapped separately.
c. Open the battery holder, put into 4 pieces AA
alkaline batteries.
d.Put the power adapter and battery holder into the
mortar. (see Figure 4)
3. Connected to water, with a boosting device for
pipeline pressure to 0.7Mpa, and check the
connectors have no leaks.
4. Remounted the protective cover, with mortar to
landfill cracks around the enclosure, sticking tiles.
5. After the mortar solidification, then remove the
protective cover.
6. Connected the solenoid valve line beyond panel
and the new plug-in of control box, then fixed panel
plate with 4 pieces long screws and cover the panel.
Note:
a.
b. Tighten the screws of the battery box to avoid the
batteries from wetting.
Don't mistake the polarity of the batteries and don't
mix the new and used batteries together

USER'S GUIDE
The sensing distance of this product is set at within
70cm away from the sensing window along the
direction of transmitting angle (with a 30cm x 30cm
white board as the reflecting surface) in the factory
with an infrared transmitting angle of about 20 do
wnward.Usually, it needn't adjust the sensing distance.
Of insist, please purchase another remote control to
adjustment.
When the toilet has not been used for a long time, the
sensor will drive the solenoid valve to flush every 24
hours to avoid the deodorizer and the sewer pipe from
drying up.

When people pass into the sensing range up to 2
seconds, flushing about 2 seconds, and flushing about
6 seconds after left. (At the time of induction, indicate
when the indicator flash once every 3 seconds; for more
than three minutes of the induction time, the indicator
light will blink rapidly)
To adjust the water flow, with a sucker to take down the
panel, with straight screwdriver to adjust the flow
clockwise, and counter-clockwise turn up the flow.
Note:
a.The sensor window of control box module must be in
beneath. (see Figure 5)
b. The indicator will flash 1 second upon connected
power, then enter standby of normal induction.
The sensor will closed water automatically when the
power voltage less than 4.4V; the indicator will flash
3 times every 6 seconds to prompted replace the
batteries if people use it.

MAINTENANCE
Clean the Filter Screen
If the flushing volume reclines sharply after
installation or used for a long time with no cause
from water pressure, the filter may need a wash.
Turn off the fixed cap with filter-key,
take out the filter, clean with a brush and reinstall it.
a. Turn off the water supply or tighten the
adjusting bolt before cleaning.
b. Carefully take out the filter when cleaning to
avoid foreign materials entering the inside
of the valve body.
Notice:
a. Do not use dust-removing powder, abrasive
powder or cleaner containing oil, acidor
alkaline ingredient.
b. Do not spray air-refresher, disinfector, or
other deodorizing,cleaning solvent directly
into the sensing window.
c. Keep wire away from water.
d. Don t attack the sensor window.
Notice:
