3. UNIT INSTALLATION
3.1 Installation Instruction
①
This electrical water heater shall be installed on a solid wall. If the strength of the wall cannot bear
the load equal to two times of the total weight of the heater filled fully with water, it is then neces-
sary to install a special support.
Incase of hollow bricks wall, ensure to fill it with cement concrete completely.
②
After selecting a proper location, determine the positions of the two install holes used for expan-
sion bolts with hook (determined according to the specification of the product you select). Make
two holes in the wall with the corresponding depth by using a chopping bit with the size matching
the expansion bolts attached with the machine, insert the screws, make the hook upwards, tighten
the nuts to fix firmly, and then hang the electric water heater on it (see Fig.2).
Install the supply socket in the wall. The requirements for the socket are as follows:250V/10A, single
③
phase, three electrodes. It is recommended to placed the socket on the right above the heater. The
height of the socket to the ground shall not be less than 1.8m (see Fig.3). If there is fault on power
cable, it should be replaced by the manufacturers, agencies or qualified person who is able to do this
so as to ensure the safety.

④
If the bathroom is too small, the heater can be installed at another place without sun-scorched and
rain-drenched. However, in order to reduce the pipeline heat losses, the installation position of the
heater shall be closed to the location shall be as near as possible to the heater.
3.2 Pipelines Connection
①
The dimension of each pipe part is G1/2" ; The massive pressure of inlet should use Pa as the unit;
The minimum pressure of inlet should use Pa as the unit.
②
Connection of pressure relief valve with the heater on the inlet of the water heater.
In order to avoid leakage when connecting the pipelines, the rubber seal gaskets provided with the
③
heater must be added at the end of the threads to ensure leak proof joints (see Fig.4).
