May cause fire or electric shock.

Before installation

1. Confirm cold /hot water pressure

● Confirm the cold water pressure is equal to or higher than that of the hot water
If water pressure is higher than 125PSI (862kPa), use a pressure-reducing
valve to reduce it to between 20 and 80 PSI (138 and 551 kPa).

●The optimal pressure ranges is 15PSI to 125PSI (100kPa to 862kPa)
Confirm that the water supply pressure is within this range.

2. Confirm the temperature of hot water supply

● Do not use steam as hot water supply.

● Make sure that the temperature range of hot water supply side is 140 to

185ºF
This is not mandatory for the lower limit but is recommended.

● The auto faucet does not discharge hot water exceeding 122ºF (50°C) .

3. Piping

● Flush all water lines prior to installation.

4. Counter thickness

● The thickness of the counter should be made in the range of 3/8 to 1-3/8
inches (10-35mm).

5. Others

● Special cares should be taken not to damage or scratch the sensor surface.

● You should prepare the stop valve, flexible hose and steel pipe.

● When using the inverter or Infrared sensor, do not set other such devices

nearby since they may cause malfunction.

● If you find water residue in the device, it is not a defect of the product.

Open the stop valve and check for water leakage.

2) Operation

<Check the body dectection sensor>

●

Insert the power plug to the AC outlet. Then, walk to the

lavatory counter and when you are approximately 15-3/4”

.

(400mm) away from the counter, the LED light is ON.

<Check the hand washing sensor>

●Place your hands under the faucet, water begins to flow.

●Water will automatically stop in 1-2 sec later after your hand s are removed.

For safety and conservation reasons, water will stop

●

automatically after 60s of detection each use.

< Check the switches>

●Water flows when Start/Stop switch is pressed.

●To stop the water flowing, press the switch again.

●It will stop automatically after 50 seconds if switch is left ON.

●When hot/cold switch is pressed, LED switch turns red. Water r eaches its

optimal temperature

●Temperature will restore by pressing it again; LED turns back to blue .

Caution

If water temperature goes opposite direction,confirm if the
hot and cold water connection is correct.

3. Cleaning of the strainer

Close the stop valve with hand.
Use the open/close tool to remove the strainer cover.

- Clean the strainer regularly after installation.

If the strainer is blocked, the flow becomes weak,
and the product will not function properly.

Open/close tool

4. Adjustment of flow rate

The flow controller regulates flow rate to 1.7 gpm
(6.5L/min) and there is no need to adjust the flow rate.

Use the product with the stop valve fully opened.

But when water flow is too strong, adjust the flow rate
by turning the stop valve clockwise.

The water appears cascade with water
flow rate of more than 1.45 gpm (5.5 L/min).
