1. CAUTIONS
Before installing this water heater,check and confirm that the earthing on the supply socket
is reliably grounded. Otherwise, the electrical water heater can not 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 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.
• The wall in which the electrical water heater is installed must 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 must be adopted.
• The supply socket must be earthed reliably. The installation height of the supply socket
must not be lower than 1.8m. The rated current of the socket must not be lower than 16A.
The socket and plug must be kept dry to prevent electrical leakage. If the flexible power
supply cord is damaged, the special supply cord provided by the manufacturer must be
selected, and replaced by the professional maintenance personnel.
• The maximum inlet water pressure is 0.5MPa; the minimum inlet water pressure is 0.1MPa,
if this is necessary for the correct operation of the appliance.
• When using the heater for the first time (or the first use after maintenance), the heater
can not 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 pressure relief valve attached with the heater must be installed at the cold water inlet
of this heater, 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. In order to drain
away the water inside the inner container, it can be drained away from the pressure
release valve. Twist the thread screw of the pressure release valve off, and lift the drain
handle upwards (See Fig.1). The drainage pipe connected to the pressure release hole
must be kept sloping downwards and in a frost-free environment. The water may drip
from the discharge pipe of the pressure-relief device and that this pipe must be left open
to the atmosphere.
• During heating, there may be drops of water dripping from the pressure release hole of
the pressure relief valve, this is a normal phenomenon. The pressure release hole shall not
be blocked under no circumstances, otherwise, the heater may get damaged, even
resulting in accidents. If there is a large amount of water leak, please contact customer
care center for repair. The pressure relief valve need to be checked and cleaned regularly,
so as to make sure it will not be blocked.
• Since the water temperature inside the heater can reach up to 75ºC, 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.
• If any parts and components of this electrical water heater are damaged please contact
customer care center for repair.
