Power Connection
Power cord and plug are equipped with the water, please ensure plug and socket are fitting.
Connect a safety valve to the inlet tube (i.e. blue cap side) of heater, keeping arrow accord with water
flow (i.e. toward the heater) (Refer to Fig.7 for more detail). Connect a discharge pipe with safety
valve. Connect the hot water pipe to the outlet tube (i.e. red cap side).
For safety valve installation, please refer to chapter of “Safety Feature". If water pressure of inlet
pipe approaches or even exceeds relief point (0.8MPa) of the safety valve, please install a decom-
pression valve on the water inlet pipe away from the heater.
Water pipe and heater are only permitted to be connected by PPR pipe.
After mounting of the heater, use three-pass discharge pipe to connect safety valve and discharge-
pipe as per Fig.7.
Ensure three-pass discharge pipe, connected with condensate water outlet, is unobstructed and
toward floor drain.
