Please read this instruction manual carefully. Should you fail to do so and as a result cause
damage to the unit, we will not take responsibility.
Installation is to be done by a plumber only.
Customers are not to attempt installation
themselves.
Read P2 “1. Safety precautions”.
Confirm all parts are included certainly before installation.
Water pressure inspection
Measure the water pressure before installation.
If the working water pressure is more than 0.35MPa
(3.5kgf/cm
2
), please adjust it to 0.2MPa (0.2kgf/cm
2
) with
reducing valve (Reducing valve is not included). The
appropriate static water pressure range is from 0.07 to
0.75MPa (from 0.7 to 7.5kgf/cm
2
), and the appropriate
working water pressure range is from 0.07 to 0.35MPa
(from 0.7 to 3.5kgf/cm
2
).
