regarding the collection systems available.
If electrical appliances are disposed of in landfills or dumps,
hazardous substances can leak into the groundwater and get
into the food chain, damaging your health and well-being.
Water temperature over 50
can cause severe burns
instantly or death 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 automatically. 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 conditions, 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.
