When using the heater for the first time (or the first use after maintenance), the heater cannot 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.
During heating, there may be drops of water dripping from the pressure release hole of the pressure relief valve. This is a normal phenomenon. If there is a large amount of water leak, please contact customer care center for repair. This pressure release hole shall, under no circumstances, be blocked; otherwise, the heater may be damaged, even resulting in accidents.
The drainage pipe connected to the pressure release hole must be kept sloping downwards.
Since the water temperature inside the heater can reach up to 75?, the hot water must not be exposed to human bodies when it is initially used. Adjust the water temperature to a suitable temperature to avoid scalding.
If the flexible power supply cord is damaged, the special supply cord provided by the manufacturer must be selected, and replaced by the professional maintenance personnel.
If any parts and components of this electrical water heater are damaged, please contact customer care center for repair.
This appliance 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 instruction 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 appliance.
The maximum inlet water pressure is 0.5MPa; the minimum inlet water pressure is 0.1MPa, if this is necessary for the correct operation of the appliance.
The water may drip from the discharge pipe of the pressure-relief device and that this pipe must be left open to the atmosphere; The pressure-relief device is to be operated regularly to remove lime deposits and to verify that it is not blocked.
In order to drain away the water inside the inner container, it can be drained away from the pressure release valve. Twist the thread screw of the pressure release valve off, and lift the drain handle upwards. (See Fig.1) A discharge pipe connected to the pressure-relief device is to be installed in a continuously downward direction and in a frost-free environment.

UNIT INSTALLATION

INSTALLATION INSTRUCTION

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. In case of hollow bricks wall, ensure to fill it with cement concrete completely.
After selecting a proper location, determine the positions 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).
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.

PIPELINES CONNECTION

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 users want to realize a multi-way supply system, refer to the method shown in fig.5 and fig.6 for connection of the pipelines.
