Function module installation locations
Install the function module indoors, in a room other than the bathroom.
Please leave a space of at least 600 mm in front of the equipment so that inspections or repairs can be made.
Also, please do not locate it on a second-story wall or other place without access.
Please take the following into consideration when deciding where to place the function module.
- The length of the cables to the equipment (pumps and the like) that will be installed with the bathtub.
(7 m or 15 m cable is available)
If the tub installation is downstairs the function module should be within 7 m of
the top of the tub.
If the tub installation is upstairs the function module should be within 7 m of
the top of the tub. In this case the supplied water pressure should be 0.20
MPa above head pressure.
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.
Precautions when plumbing
• If the plumbing materials are specifi ed by the relevant local and national plumbing authorities, comply with
those specifi cations.
• Be sure to fl ush fi lings, sand and debris from inside the pipes using water before connecting the function
module.
• Use a union junction or similar means on the connection port and do not use excessive force.
• The diameter of the pipe is not to be less than the diameter of the function module connector (G3/4).
• When the water pressure is high, either install a pressure-reducing valve or a device to prevent “water
hammers.” (Recommended water pressure: 0.20 to 0.75 MPa).
• Keep the number of unions as small as possible and do not use complicated plumbing. Additionally, do not
plumb in such a way that air can become trapped in the pipes.
Hot and cold water supply plumbing
• Install an anti-backwash valve, a shut-off valve or a shut-off valve with an anti-backwash valve near the hot and
cold water supply ports.
• In order for the customer to have a pleasant experience using this equipment, a hot and cold water supply
pressure of 0.20 to 0.75 MPa is required. If the water pressure is low, the equipment will not function properly
and could lead to trouble with the customer, so be prepared to install a booster pump as a countermeasure.
Fill-tub plumbing
• The pipes that are used with the fi ll-tub feature are to have a maximum length of 15 m and 10 changes of
direction.
• Please incline the pipes so that it will be easier to remove water from the pipes when draining water from the
pipes.
