(2) Function module installation
● The weight of the equipment will hang on the installation wall, so it should be reinforced if it isn't strong enough.
The supporting structure should be capable of supporting at least 40 lbs (18 kg).
● When installing the equipment, do not drop it or hit it against anything.
Doing so could break or damage the parts inside the equipment.
● Be sure to install it on a vertical wall.
● The plumbing that is connected to the equipment should be installed so that there will be no safety problems with
respect to earthquakes, other vibration or physical impact and caulking material should be used to seal the points
where the hot and cold water and the power lines pass through the walls.
