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 to reduce the pressure and 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 condensed 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 cannot 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.
