Maintenance
▲
The appliances should be checked and maintained periodically by a competent person
▲
Check the gas tube/pipe regularly for any defect. Contact service center for any doubt.
Always check the gas pipe for cracks.
▲
Always check for leaking water.
▲
Ask qualified technicians to examine the burner, flue and fan once a year.
▲
Always check the flame inside the water heater for any abnormal conditions.
▲
Keep the cover of the water heater clean.
▲
This product uses water pressure to open the channels. When the water pressure is lower
than 0.2bar, the heater cannot be ignited.
▲
The drain valve is dripping. When the water pressure is too high, the drain valve will release
the water so as to reduce the pressure to protect the heater.
▲
When the heater is supplying hot water to several points at the same time, the hot water flow
would be reduced, or no hot water will issue at all.
▲
When the temperature outside is too low and the exhausted gas meets the cold air, it will be
condense as white fog. This is normal.
▲
When the water temperature is too high, set to a lower temperature and reduce the water
tap. If the water temperature outlet is too high, please open the tap to reduce the temperature.
▲
When the water temperature is too low, and the hot water volume is so high so that it
exceeds
the
heater’s
heating
power,
the
outlet
water
will
be
not
hot
enough,
please
reduce
the
water
volume.
▲
In order to ignite immediately, the fan in the appliance will delay running for a long time and
then stop automatically. This is normal.
▲
When you use the multi‐function shower, the resistance may be too large, and the water inlet
pressure
will
be
too
low
or
the
water
inlet
volume
will
be
too
little
(below
the
starting
–up
water
volume),
there
may
be
flameout
or
can
not
be
ignited,
please
choose
the
suitable
shower
function.
▲
The residual water in the heater may be frozen in the winter, this is bad for the heater, so you
must drain the water after use. (Please refer to the drain methods.).
▲
In order not to create scaling, please close the gas valve after using the heater, let the hot
water out of the appliance. When the outlet of the hot water is cold, close the cold water valve.
