Children, disabled and elderly
are at highest risk of being
scalded. Feel water before
bathing or showering.
Water temperature limiting
valves are recommanded.
Do not operate the unit with a wet hand.
An electric shock may be caused.
The installation height of power supply
should be over 1.8m, if there is any water
spattered, separate the power supply
from water.
A one-way valve must be installed on the
water inlet side, which is available from
accessories, see manual "accessories"
part.
It's normal if some water drops from the
hole of PT valve during operation. But, if

hot water tap for several minutes at the
kitchen sink before using any electrical
appliance connected to the hot water system.
When hydrogen is present, there will probably
be an unusual sound such as air escaping
through the pipe as the water begins to ow.
