Connect with the tip of

Since the male and female screw portions are formed on each of the joints 22, 23, the positioning plate 2 is attached to the faucet mounting wall.
At the front side of B1, the faucet mounting wall B1 and the joints 22, 23 are tightened and fixed. At this time, the fitting portion 2d of the positioning plate 2 is fitted into the water discharge fitting mounting hole B2 to prevent rotation, and can be securely fixed.

Next, a water outlet nozzle 24 is attached to the tip of the water outlet side joint 22, and a sensor side connector 32b connected to one end of a lead 33 from the hand sensor 3 previously mounted in the water outlet cover 20 is connected to the connector 32b. It is connected to the control device side connector 32a held by the holder 4.

Then, the spout cover 20 is fixed to the fixing screws 27,2.
8 Attach to positioning plate 2 with.

Thereafter, the hand washer B itself is attached and fixed to the wall W with bolts or the like, and the flow path side joint 23 and the hot and cold water supply pipe 5 are connected on the back side of the wall W, and the sensor cord 31 is connected to the control box 7. Connect and finish the work.

Next, in the wall-mounted hand washer B mounted as described above, if the hand-sensing sensor 3 housed in the spout 1 of the automatic faucet A of the same hand washer B fails. , About the actual work for taking out the sensor 3
This will be described with reference to FIGS.

First, the fixing screw 2 is fixed from the water outlet cover 20.
7 and 28 are loosened and removed, and the spout cover 20 is detached from the mounting wall B1 of the hand washer B.

However, since the hand detection sensor 3 is mounted in the water outlet cover 20 and the lead wire 33 derived from the sensor 3 is connected to the cord connector 32, the water discharge cover 20 is still removed. It is not possible.

Therefore, the water outlet cover 20 can be completely removed from the mounting wall B1 by extracting the sensor-side connector 32b from the control-device-side connector 32a held by the connector holder 4.

At this time, since the controller-side connector 32a is held by the connector holder 4, it does not fall to the back of the wall, and the water outlet cover 20 can be removed with ease and extremely easily.

Next, the hand sensor 3 is connected to the water outlet cover.
The hand detection sensor 3 can be easily taken out by loosening and pulling out the fixing bolt 3m screwed to the screw 20.

Needless to say, when the taken-out hand sensor 3 is repaired and then attached to the spout cover 20, it can be easily attached in the reverse order of the above description.
