Usage and maintenance

The urinal sensor valve is designed and manufactured based on pyroelectric infrared radial sensor technology, so it is safe to use. It will bring a comfortable and modern life to you thanks to its designed features.

Step 1: If a user moves in the sensor area, the indicator light will flash when using battery and it will be on when using electricity to notify detection of the user.Step 2: After 3 seconds, if it still detects the user in the front, the device will automatically open the valve for wet flush for 2 - 5 seconds (optional). Within 45 seconds after this flush, if there is user presence, it will not perform such wet flush again. This is smart feature to save water.Step 3: The device will wait until the user moves out of the sensor area, it will automatically flush the urinal cleanly for 6 - 12 seconds (optional).

Maintenance during use

Glass maintenanceAfter operating in the moist and dusty environment for a time period, the device’s glass may be foul due to these factors. Thus, it is necessary to clean the glass.

Solenoid valve maintenance

After a period of usage, if flushing water becomes weaker or the valve starts leaking, it means the solenoid valve needs to be cleaned. This task should be done by technicians.

How to clean the solenoid valve:

Step 1: Disassemble the device’s glass and disconnect its power or battery supply.

Step 2: Disassemble the valve hose, leave the device’s front cover at dry place.

Step 3: Lock water supply for the valve.

Step 4: Disassemble the pipe which conveys water to the urinal.

Step 5: Use appropriate tool to remove the filter from the solenoid valve.

Step 6: Clean the valve filter.

Step 7: Reassemble and check the device’s feature.

Replace batteries

When the indicator light flashes every 1 second, it is time to replace batteries. The device uses 4 Alkaline 1.5V – AA batteries.

After the preset time, the device will perform wet flush, flush duration is 2 - 5 seconds (optional). When detecting a user getting out of its sensor area, the device will continue to cleanly flush water for 6 - 12 seconds (optional). Within the next 45 seconds, in case of another user, it only cleanly flushes water for 6 - 12 seconds (optional) after detecting the user getting out of the sensor area.

If there is no other use in 45 seconds, it will automatically return to the initial procedure. It is the smart feature to save water during use.

If there is no other use for 12 hours, it will automatically flush water to rinse the urinal for 2 - 5 seconds (optional). This smart feature will make the urinal absolutely clean.

25

The device does not flush or stop flushing.CheckingThe valve is installed in the opposite direction and the water supply has a lot of residue.The solenoid valve is not connected to the controller. If the problem is not mentioned above.SolutionCheck the valve installation based on instruction steps in the manual.Connect the solenoid valve to the controller.Please contact Customer Contact Center or the shop from which you purchased.

The light flashes continuously (electric valve) or the device does not work properly.CheckingThere is any obstacle in the device’s sensor area.The device is installed on the opposite side of the mirror within 2.5 m.The device is close to light source from incandescent lamp.If the problem is not mentioned above.SolutionRemove the obstacle from the sensor area.Move the mirror because it reflects the infrared signal in the device’s sensing component.Adjust the direction of the light to avoid reflection towards the device or replace an energy-saving bulb.Please contact Customer Contact Center or the shop from which you purchased.

Problem and Solution

Problem 1

Problem 2

26

The indicator light does not flash when there is a user in the sensor area.

CheckingThe power line, battery wire are not connected correctly.A user wears full black coat or shirt (black leather jacket, black coat, etc.)

SolutionConnect the power cable, battery wire properly based on the steps in the manual.Black absorbs infrared signals fully so please put your hand in front of the transceiver eye so that the device flushes water. Please contact Customer Contact Center or the shop from which you purchased.

Flushing water is too much or too little.

CheckingThe device’s switches are not correctly set up based on its requirement.The device’s switch is adjusted but flushing water is still too much.

SolutionPlease refer to the mode settings in page 11 and follow the instructions to set up the mode correctly according to users’ needs.Please adjust pressure regulator of water supply because the water pressure at your place is too high.Please contact Customer Contact Center or the shop from which you purchased.

Problem 3

Problem 4

27

Other problems.

CheckingTechnicians misplaced the distance between the valve and the urinal (too far or too close), it is difficult to install the pipe.Water leak at the joints occurs.It is difficult to screw from the bottom because the performance scale is small.

SolutionYou can buy hoses at the sanitary equipment stores such as the type used for sink, measure suitable distance, cut and install.Please check the rubber gaskets, wrap thread seal tape (teflon tape) at the points of screws and the rubber stopper’s slots, etc.Short screwdrivers should be used. This type of screwdriver is sold at mechanical appliances shops.
