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. Inspect
frequently whether the plugs contact well with the socket. Inspect method is as follows: insert
the power supply plug into socket, after using for half an hour, shut down the unit and pull the
plug out, and inspect the plug whether it scalds hand. If it scalds (over 50℃), please change
another well-contacted socket to avoid the plug being damaged, fire or other personnel
accidents result from bad-contacting.
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.
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.

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 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.
