First determine the installation position of the water heater based on your needs. Use PP-Rpipe
recommended for installation. It should be such that maintenance, repair and dismantling of
the water heater is convenient. Furthermore install loose joint at suitable locations for the water
intake and outlet.
Use impact drill to drill two 65mm-holes with a diameter of 12mm each at the locations based on
the installation requirements. Insert the expandable hooks into the holes and ensure that they are
properly fixed. Hang the water heater vertically on the expandable hooks and check whether it is
securely fixed. Install the safety valve and drainage pipes, etc. as indicated in the illustration. Make
Determine the water supply's position and connect the water outlet and intake to their respective
positions. Fill the inner chamber with water to check whether there is any water leakage. If so, the
connections must be re-done and properly carried out.
The water heater is a wall-mounted type; thus it should be securely mounted on the wall so that it
can withstand 4 times its weight after it is filled with water.
Adequate space should be reserved during installation of water heater for ease of subsequent
repair and maintenance. When installation care should be taken in order that the water heater is
of a safe distance from gas pipe. It should be at least half a meter from gas cookers/gas pipe/gas
meter, etc.
Make sure the pressure on the water intake is not less than 0.05MPa, and not more than 0.75MPa.
The water heater should be installed indoors in a place where the ambient temperature is above 0°C.
The pipes should be closely laid out. The hot water outlet should be too far away from the point of
usage. If the distance exceeds 8 metres, the hot water pipe should have insulation protection, in
order to prevent heat loss.
Do not reverse the installation for the water intake and outlet. The safety valve should be installed in
the designated position and not
moved without permission. The safety valve's pressure-relief hole
should be connected to the atmosphere and free from blockage at all times.
To ensure safety, the water heater should be connected to independent sockets (do not use
adapters), with reliable earthing. In addition the power socket must conform to national standards.
Use pen multimeter to check whether the live line and zero line are reverse. Turn on power supply
only when you have ensured that the heater is filled with water and that there is no water leakage.
The power supply should also conform with requirements.
Note: Make sure that the water heater is securely attached to the hook before letting it go;
otherwise it may drop and cause injury or property damage.
Safety reminder: In order to prevent accidents, pleae use our company's accessories during
installation. Do not replace them on your own or use substitutes. Please make sure
to contact our Maintenance Department if the accessories are damaged and
replace them with the accessories supplied by our company. Our company shall not
be liable for any direct or indirect losses caused as a result of accidents for failure to
comply with the aforesaid.

or designated installation personnel.
The water heater is wall-mounted type.
Install the safety valve which has a rated pressure of 0.80MPa (its connection is G1/2) into the
water intake pipe with the arrow on the safety valve pointing at the water heater. When the
pressure relief hole due to the expansion of water in the heater. The pressure-relief hole should
be connected to the atmosphere and free from blockage at all times.
Attach an end of the water drainage pipe onto the pressure relief hole
on the safety valve. You may cut the water drainage pipe to make it
shorter, or extend it depending on the situation. Connect the other
end of the water drainage pipe to the lower water outlet. This will
prevent the water from the pressure relief hole from splashing.
The water drainage pipe connected to the safety valve should be
installed in a slanted manner and in an environment which is not
prone to frost. Make sure that the connections are not leaking and
that the power supply conforms with requirements. Test the machine by switching on the
power.
All water pipes should be installed by qualified water pipe installation workers. The pipelines
should comply with the national standards and regulations on the prohibition of prevention tools to
draw water to water source pipelines by way of inverse siphon, as well as local building codes.

Instruction manual
Cleaning and Maintenance
Adjust the water temperature knob at
the bottom of the water heater to set the
temperature.
Maximum water temperature setting is 75°C
Temperature adjustment knob: Turn the
knob gradually clockwise to raise the
temperature setting. The knob will not
continue to turn once it reaches maximum
temperature setting. Turn it anti-clockwise
gradually to reduce the temperature setting.
If the heating indicator light is lit, it means that the water heater is heating.
If the heating indicator is power off, it means that heating is finished and it will enter
heating insulation state or get closed totally.
External cleaning
Take a wet cloth and dab it with small quantity of neutral detergent. Lightly
wipe the water heater. Do not use petrol or other solvents. Finally use a dry
cloth to wipe; make use to dry the water heater thoroughly. Make sure not to
use detergents containing abrasive agents (e.g. toothpaste), acidic substances,
Internal cleaning
In order to ensure that the water heater will work with high efficiency, clean the
heating tube and inner chamber once every three years. Take care not to damage
the exterior of the heating pipe and the protective layer on the surface of the inner
chamber. Depending on the local water quality and usage habit, the Anode rod
should be regularly replaced. If maintenance is required, please contact the local
Maintenance Department.
When the water heater is in use, the safety valve should be checked once every
month. To check it, turn the safety valve's small handle on the side of the water
out. In the event of damage to the safety valve, please replace it with a safety valve of
similar specifications.
Regularly engage service personnel to carry out safety inspection and promptly clear
the water heating pipes of the scale. Check also the consumption of the Anode rod;
change it if consumption becomes excessive.
chemical solvents (e.g. alcohol) or polish to clean the water heater.
If the water heater is not used for an extended period of time, please carry out the following steps:
When the water heater needs to be used again, our recommendation is to open hot
water valve before switching on the power in order to prevent accidents. Allow any gas
that may be trapped in the pipe to be discharged. Do not smoke or allow other exposed
fire to be near the opened valve. At the same time, make sure to carefully examine all the
parts of the water heater and ensure that they are in a perfect condition. Make sure to fill
the inner chamber with water before use.
When the water temperature reaches the set temperature, it will enter
thermal state.Once it lowers to certain temperature, power will be
automatically connected.
Do not connect the power before filling the inner chamber with water in order
to prevent damage to the water heater.
Adjust the water temperature to the suitable level before use in order to prevent
scalding.
Insofar as there is adequate hot water, set a lower temperature to reduce heat
loss, high temperature corrosion and scaling. This will extend the water heater's
lifespan.
otherwise it may cause fire.
Observe the water drainage of the safety valve's pressure-relief hole.
When the water pressure is 0.75MPa and the pressure-relief hole on the safety valve
emits large volume of water, it means that the water pressure is excessive. In such
case, please notify the After-sales Department.
