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.
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
heater must be added at the end of the threads to ensure leak proof joints (see Fig.4).

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 necessary to install a special support.
Incase of hollow bricks wall, ensure to fill it with cement concrete completely.
After selecting a proper location, determine the positons of the two install holes used for
expansion bolts with hook (200mm), 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 electrical 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 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 the bathroom is too small, the heater can be installed at another place. 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.
