The function module requires a hot water supply temperature of at least 140°F (60°C). (No more than 158°F (70°C).
If the supply temperature of the hot water is too low, it won't be possible to fill the tub to the temperature setting on
the controller.
The function module mixes the supply of hot and cold water and runs hot water out of the fill-tub outlet, so the
temperature of the water flowing out will be lower than the temperature of the water being supplied to the function
module.
The pressure of the hot and cold water supplied to the function module must be at least 29 psi (0.20 MPa) (when
flowing). (No more than 108.75 psi (0.75 MPa)).
The pressure differential of the cold water is to be greater than that of the hot water and kept within
14.5 psi (0.10 MPa).
If the pressure is low, the water won't flow out like a waterfall. Additionally, it will take longer for the tub to fill with hot
water.
Supply Equipment Specifications
o Supply Pressure 29 to 108.75 psi (0.20 to 0.75 MPa)
o Supply Temperature 140 to 158°F (60 to 70°C)
o Hot water usage
• Max. temperature 113°F (45°C)
• Max. flow rate 9.2 gal/min. (35 L/min.)
• Max. capacity 145 gal. (550 L)
The diameter of the function module connector is NPT 3/4. Please do not make the diameter of the plumbing smaller
than the diameter of the connector to the function module.
The use of equipment below full capacity could lead to problems for the clients.
It is necessary to have space between the tip of the water pipe drainage. If not the water could backflow.
15
5-3 Clean-up Shower Installation Conditions
● When attaching the Clean-up Shower, please observe the following conditions of use.
(1) Confirmation of water pressure
Supply hot/cold water pressure:
❈ If the supply water pressure exceeds 108.75 psi (0.75 MPa), please reduce the pressure to around 29 psi
(0.20 MPa) using a commercially available pressure-reducing valve.
Minimum required pressure: 11.6 psi (0.08 MPa)
{
Maximum water pressure: 108.75 psi (0.75 MPa)
(2) Confirmation of hot water supply temperature
● Please keep the hot water supply temperature no higher than 158°F (70°C).
Note also that for safety, we recommend a hot water supply temperature of 140°F (60°C).
● Please do not use steam in place of a hot water supply.
(3) Plumbing
● Please do not connect the hot and cold water backward.
Note also that in order to reduce resistance, the shortest distance possible should be used for the hot water supply
pipe from the hot water heater and insulation should be wrapped around the plumbing.
● Please implement countermeasures for freezing such as wrapping insulation around the pipes.
16
5-4 Function module installation locations
Within 7m
Within 7m

A 23 ft. (7 m) or 49 ft. (15 m) cable is provided.
- A height which allows the plumbing to be inclined so that the bathtub can be drained more easily when removing the
water.
Please install in a location that will not cause damage if there is water leakage.
If you install in a location that can cause damage please add water protection and appropriate drainage on the floor.
If the tub installation is downstairs the function module should be within 23 ft. (7 m) of the top of the tub (see diagram).
If the tub installation is upstairs the function module should be within 23 ft. (7 m) of the top of the tub (see diagram).
In this case the supplied water pressure should be 29 psi (0.20 MPa) above head pressure.

(5) Plumbing the equipment
■■
Precautions when plumbing
• If the plumbing materials are specified by the relevant local and national plumbing authorities, comply with those
specifications.
• Be sure to flush filings, 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 (3/4).
• When the water pressure is high, either install a pressure-reducing valve or a device to prevent "water hammers."
(Recommended water pressure: 29 to 108.75 psi (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
29 to 108.75 psi (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 fill-tub feature are to have a maximum length of 49.2 ft (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.
• Please allow sufficient space for the end of the water-removal pipe and the drain opening.
If there is no space, backed up water could flow back inside.
28
(6) Inspecting for leaks in the fill-tub plumbing
Booster pump
Gauge
Caution
• Do not apply additional pressure to the equipment.
Inspection pressure and time: 43.5 psi (0.30 MPa) for five minutes or longer.
➀ Install a valve on one end of the fill-tub plumbing. (Valve open.)
➁ Install a booster pump on the other end to feed water into the fill-tub plumbing.
➂ Once the air has been removed from the fill-tub plumbing and it has been filled with water, close the installed valve.
➃ Inspect for leaks.
Inspection pressure and time: 43.5 psi (0.30 MPa) for five minutes or longer.
• Use a pressure meter that suits the pressure being checked when inspecting the pressure.
• Be sure that there are no leaks or pressure drops across the gauge.
❈ Do not apply pressure to the equipment itself.
❈ If pressure leaks are discovered, run the test again after fixing the leaky areas.
