Before Installation
z Since the position of the spout opening depends on the mounting position of the
tub filler rough, pay enough attention to the mounting position.
z If the water supply pressure exceeds 1.0 MPa, reduce the pressure to about 0.5
MPa using a commercially available pressure reducing valve.
We recommend a water supply pressure of about 0.5 MPa for comfortable use of
the faucet.
z If you use the product at a large flow rate because the water pressure is high, etc.,
you may feel extra resistance using the diverter valve.
In such case, reduce the flow rate from the handle.
z In order to prevent scalding due to unsafe operation, the cold water supply
pressure must be set higher than or equal to the hot water supply pressure.
If increasing pressure on the hot water side, make sure the hot water supply
pressure side is set lower than the cold water side.
z In order to prevent scalding, set the temperature of the hot water in the hot-water
supply less than 60°C.
For a comfortable water temperature, we recommend that you set it to 60°C.
z Connect the hot-water supply pipe at a minimum length from the water heater
in order to reduce resistance and make sure to wrap the water supply pipe with
thermal insolation.
z Water may remain in the product from flow tests conducted before the product is
packaged, this does not indicate that something is wrong with the product.
Installation of the tub filler rough
1
Remove the plaster guard of the tub filler rough using a Phillips screwdriver.
Since the plaster guard and the screws will be used later, put them in a safe
location where they will not be lost.
Install and anchor the tub filler rough so that it is level.
The plug without the z mark faces the spout.
Confirm the position of the bathtub, roughly decide the installing
direction and then anchor the tub filler rough.
*When anchoring the faucet main body, the direction of the spout
is adjustable.
Plumbing
2
When connecting pipes, use sealant, confirm the C/H marks on the tub filler
rough so that the cold-water pipe and the hot-water pipe are not inversely
connected, and connect the piping to the tub filler rough.
Clean the inside of cold-/hot-water supply pipes
3
Connect the hose joint and a commercially available hose (Ø XX mm) to the
tub filler rough, clean the inside of the C/H water supply pipes and flush out
debris and sand remaining in the pipes.
If the inside of the C/H pipes is not clean, the debris and sand in
the C/H pipes will clog the filter and the following phenomenon will
occur.
(1) Decreased/too little water volume.
(2) Reduced functionality of temperature control
Conducting a pressure test
4
Conduct a pressure test, make sure that no water leaks from the pipe
connections and set the plaster guard.
The pressure can be applied at a maximum 1.6 MPa (static) for up to 1 min.
Finishing the floor
5
Finish the floor so that it is within the finishing range indicated on the side of
the plaster guard.
Pay attention not to get mortar, etc. inside of the plaster guard.
Cutting the plaster guards
6
Cut the plaster guard at a height of 10 mm from the finished floor surface and
remove the plug, the bolt and the blocking lid from the tub filler rough.
If the finished floor exceeds the finishing range, the cover of the
faucet main body, etc. cannot be mounted properly, therefore
make arrangements beforehand about the floor finishing.
