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.
