IMPORTANT CONSUMER INFORMATION
CONSUMER RESPONSIBILITIES
Do not directly flush the sensor with water. The sensor is an
electronic instrument.
Keep the sensor clean.
Do not use eradicator, abrasive powder or oil, acid or alkali
liquid detergent.
Do not spray air freshener, disinfectant or other kinds of
odious removing, cleaning organic liquid to the sensor directly.
Urinal is designed for use with potable water.
Avoid water that includes a lot of contaminants or acid/lakali
water and impure water.
When AC power unit is connected to 220V AC power supply,
corresponding protective measures should be taken.
Please confirm no water penetration at the connection area of
AC wire, and the connection area is not easy to be affected
by damp.
Don't connect power unit to AC power supply until the sensor
installation is finished.
220V
The head AC power supply must be protected with
appropriate fuse.
Please confirm the AC power supply and water supply should
be shut off before maintaining the products with AC power
related.
All electrical connection must be compliance with related
regulation and codes.
All installation staff should be well familiar with installation
instruction.
If you live in a hard water area, make certain that the holes in
the toilet rim are kept clean to ensure proper flushing. Toilet
bowl cleaners should be used at least once a week. Use a
long-handled brush to clean the rim holes, and to clean as far
into the trap as possible to prevent mineral deposits from
forming.
Most toilet bowl cleaners are not harmful to the vitreous china
surface of the urinal. Please follow the bowl cleaner
manufacturer's instructions carefully.
Do not use abrasive cleaners or solvents.
Do
not use cleaners inside the wash basin. Products
containing chlorine (calcium hypochlorite) can seriously
damage fittings in the urinal. This damage can cause
