CAUTIONS
Before installing this electrical water header, check and confirm that the earthing on the supply
socket is reliably grounded. Otherwise, the electrical water heater cannot be installed and used. Do
not use extension boards. Incorrect installation and use of this electrical water heater may result in
serious injuries and loss of property.
SPECIAL CAUTIONS
• The supply socket must be earthed reliably. The rated current of the socket shall not be lower
than 10A. The socket and plug shall be kept dry to prevent electrical leakage.
• The installation height of the supply socket shall not be lower than 1.8m.
• The wall in which the electrical water heater is installed shall be able to bear the load more than
two times of the heater filled fully with water without distortion and cracks. Otherwise, other
strengthening measures shall be adopted.
• The pressure relief valve attached with the heater must be installed at the cold water inlet of this
heater (see Fig.1), and make sure it is not exposed in the foggy. The water may be outflowed
from pressure relief valve, so the outflow pipe must open wide in the air; The pressure relief
valve need to be checked and cleaned regularly, so as to make sure it will not be blocked.
• When using the heater for the first time (or the first use after maintenance), the heater cannot be
switched on until it has been filled fully with water. When filling the water, at least one of the
outlet valves at the outlet of the heater must be opened to exhaust the air. This valve can be
closed after the heater has been filled fully with water.
• The water heater is not intended for use by persons (including children) with reduced physical,
sensory or mental capabilities, or lack of experience and knowledge, unless they have been
given supervision or instructions concerning use of the appliance by a person responsible for
their safety. Children should be supervised to ensure that they do not play with the heater.
• During heating, there may be drops of water dripping from the pressure release hole of the
pressure relief valve. This is a normal phenomenon. If there is a large amount of water leak,
please contact customer care center for repair. This pressure release hole shall, under no
circumstances, be blocked; otherwise, the heater may be damaged, even resulting in accidents.
• The drainage pipe connected to the pressure release hole must be kept sloping downwards.
• Since the water temperature inside the heater can reach up to 75, the hot water must not be
exposed to human bodies when it is initially used. Adjust the water temperature to a suitable
temperature to avoid scalding.
