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), theremay 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 drainthe 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.
Cleaning: The water heater should be cleaned annually, keep the dust away from flue gas
passageway. See the Cleaning Instructions below.(Only for service engineer)
1).Turn off power, shutoff gas supply;
2).Wait one hour to cool down water heater;
3).Remove the front cover, by taking out Cover Screw;
4).Using compressed air or equivalent to clean the area between the fins and the heat exchanger;
5).Do not unscrew or move any other parts of water heater;
