Doing so may cause a malfunction or current leak.
Use pr o hi b i t e d near wat e r
● Be sure to install an overcurrent breaker and earth leakage
circuit breaker in order to prevent danger
Electric wire: Use a 600V plastic shielded electric wire or cable
(A ø1.6 mm or ø2.0 mm single wire, or 2.0 mm stranded wire)
●
Insulate and waterproof the power wire connector
REQUIRED
● Do not insert the power wire connector inside the device
Doing so may cause electric shock, a current leak, or a fire.
・Thoroughly discuss the relevant procedures before performing water and
electrical work.
・The power wire is to be provided on-site. (220-240V AC type only)
・A grounding wire is not needed, so use a two-core power wire. (220-240V AC type only)
・Water supply pressure ranges from 0.07 MPa (9 L/min [dynamic]) at minimum to
0.75 MPa at maximum. Use the product within this pressure range.
・Be especially careful not to damage the surface of the sensor.
・This product is an electrical appliance. Be careful not to spray water on it.
The exposure angle and detection distance of the sensor are as shown in the
diagram. When installing a handrail or the like in front of the urinal, do so in a way
that does not obstruct the detection areas (both the stable detection area and
unstable detection area) of the photoelectric sensor. Avoid installing the product in a
location that is highly reflective (such as in a location where a stainless steel wall is in
front of the photoelectric sensor), as this could cause malfunctions.
・The product may not function in environments exposed to strong sunlight.
・Inverters or other devices that use infrared light could cause malfunctions.
・A water supply inspection has been conducted prior to packaging. There may be
some water remaining inside the product, but this is normal.
