Bypass valve
Normally, the bypass valve is fully opened. If the unit is started up with the
valve fully closed, water supply may reach abnormal high pressure
depending on external piping conditions. Be sure to keep the bypass valve
fully opened for initial startup of the unit installed.
Adjust the bypass valve to obtain required pressure and flow rate by
checking on the external pressure gauge and flow meter that can be
prepared by customer or mounted on external piping.
When any abnormality is found, press the [OFF] switch immediately to
stop the unit and turn the power supply breaker off.
