CLEANING INSTRUCTIONS
IMPORTANT CONSUMER INFORMATION
Check and ensure that all connections are tight. Open the drain. Turn on main water supply and check for leaks.
Repair leakage when necessary.
1. Light indicator Key
The indicator is the only and effective way to learn the faucets working conditions. So the users can use the
sensor faucet correctly with knowing the meaning of the sensor indicator’s flashing.
• The indicator flashes every 6 seconds (DC type) indicates that the unit is out of battery and has stopped
working. Release batteries.
• The indicator flashes every 2s: as for DC type faucets, this indicates the unit is out of battery and ceases
working. Please replace batteries.
• Under normal condition, the water will flow and the indicator will flash once when objects are detected. (The
indicator does not flash when faucet stops flowing).
