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).

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
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.
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.
