connected tightly.
How to check the power supply socket and
plug are qualified?
Turn on power supply and keep the unit
running for a half hour, then turn off power
supply and plug out, check
whether the socket and plug is hot or not.
Before cleaning, be sure to stop the opera
tion and turn the breaker off or pull out the
power plug.Otherwise, an electric shock
and injury may be caused.
Water temperature over 50
℃
can cause severe burns
instantly from
scalds. 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
there is a great amount of water, call your
service agent for instructions.
After a long term use, check the unit base
and fittings.
If damaged, the unit may sink and result in
injury.
Arrange the drain pipe to ensure smooth
draining.
Improper drainage work may cause wetting
of the building, furniture etc.
Do not touch the inner parts of the
controller.
Do not remove the front panel. Some parts
inside are dangerous to touch, otherwise a
machine malfunction may be caused.
Do not turn off the power supply.
System will stop or restart heating auto
matically. A continuous power supply for
water heating is necessary, except service
and maintenance.
If the unit has not been used for a long
period of time (2 weeks or more),
hydrogen gas will be produced in the water
piping system.
Hydrogen gas is extremely flammable. To
reduce the risk of injury under these condi
tions, it is recommended that open the 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
flow. There should be no smoking or open
flame near the tap at the time it is open.
