Before installing the NEOREST

 The function module must not be installed in the bathroom.

In addition, the function module is not waterproof and should not be installed outdoors. Be sure to install the function module indoors other than in the bathroom.

 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 of 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 difference of water pressure between cold water and hot water should be such that the cold water is kept higher and 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

Supply Pressure: 29 to 108.75 psi (0.20 to 0.75 MPa) Supply Temperature: 140 to 158°F (60 to 70°C) Hot Water usage: Max. temperature 113°F (60°C) Max. flow rate 9.2 gpm (35 L/min) Max. capacity approx. 144 gallons (545 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 customer.

 Use a sealant on the taper thread joint.  It is necessary to have space between the end of the drain hose and the drain. If not the water

could backflow.

 Power supply connection The power inlet of the function module must be connected to the per-

manently installed power outlet (cable).

Function module installation locations

 Install the function module indoors, in a room other than the bathroom.  Please leave a space of at least 24 inches (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 are 49 ft (15m).

 If the tub installation is downstairs the function module should be

within 23 ft (7 m) of the top of the tub.

 If the tub installation is upstairs the function module should be

within 23 ft (7 m) of the top of the tub. In this case the supplied water pressure should be 29 psi (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 in-

stalled 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 specified by the relevant local and national plumbing authorities, com-

ply 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 (NPT

3/4).

 When the water pressure is high, either install a pressure-reducing valve or a device to prevent

“water hammer”. (Recommended water pressure: 29 to 108.75 psi (0.20 to 0.75 MPa) However, limits set by local and national plumbing authorities should not be exceeded.)

 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 ft (15m) and 10

changes of direction.

 Please incline the pipes so that it will be easier to remove water from the pipes when draining water

Shower Installation Conditions

1. Confirmation of water pressure

● Supply hot/cold water pressure: Minimum required water pressure (when flowing): 11.6 psi (0.08 MPa) Maximum water pressure (when not flowing): 108.75 psi (0.75 MPa)

● 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.

2. Confirmation of hot water supply temperature

● Please keep the hot water supply temperature no higher than 158°F (70°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.

● Please install the hot water supply pipe at the shortest distance from the water heater to reduce the resistance.

4. Local and national codes

●Adherence to all local and national codes is required and take precedence over requirements listed in this manual.

5. Tempering valve (supplied)

●The shower hot water output will be limited by the tempering valve. The tempering valve is preset to 105°F (41°C)

●Check codes for compliance and adjust if needed. The tempering valve is located under the shower near the tub frame. Below is the method of adjustment.
