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).
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.
Install the supply socket in the wall. The supply socket be 220V. 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.
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, 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).
