Cleaning and Maintenance

Packing list　

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 water heater is heated by electricity, a small amount of waterwill flow from the safety
valve's pressure relief hole due to the expansion of water in the heater. This is normal. The
pressure-relief hole should be connected to the atmosphere and
free from blockage at all times.

When installing the water heater, certain space should be reserved (not less than 250mm
from the top and bottom, and not less than 700mm from the front and the sides) for ease
of subsequent maintenance and repair. If the water heater was to be built into clip boards,
the bottom section of the clip board should be movable for ease of removal of plastic cover
during maintenance.

Installation method for safety valve's drainage pipe: 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 to 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.

Note: If your water heater is not installed in a bathroom with sewer, our recommendation
would be that you add safety valve water drainage pipe.

Make sure the pressure on the water intake is not less than 0.05MPa, and not more than

0.8MPa.

After completion of installation, make sure to turn on the water intake valve and mixing
valve since there is no water in the inner chamber. Turn the mixing valve to the maximum
for hot water outlet. Turn off the out-flow valve when water flows out from the sprinkler or
the water outlet (indicating that the container is filled with water). Turn off the water outlet
valve. Inspect all connections to ensure that there is not water leakage before connecting
to power.

• Power will be automatically cut off when the water temperature reaches the set temperature.

Once it lowers to certain temperature power will be automatically connected.

• When the water pressure is ≥0.8MPa 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.

The water heater should be installed indoors in a place where the ambient temperature is
above 0ºC. 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 meters, the hot water pipe should
have insulation protection, in order to prevent heat loss.
The wall on which the water heater should be strong such as it is able to withstand twice
the weight of the water heater when filled with water. If the wall was not weight-bearing
wall or made of hollow bricks, adequate protective measures such as addition of support
and high-strength wall screw with back panel should be adopted.
The water heater should be installed in places such as it is easy to use and maintain and
with floor drain. In order that it will not cause damage to nearby facilities or those in the
lower levels during a leakage of the water tank or water pipe. It should not be installed
over toilet bowls, bathtub, wash basin or door frame in order that users do not feel
oppressed or insecure.
Power socket for the water heater should be installed in dry places which do not easily
come into contact with water, in order not to affect the heater’s normal operation (it would
be best equipped with protective cover).
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.
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.

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.

Must be installed by personnel in our company's After-sales Department or designated
installation personnel.

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 pipes or accessories are damaged and replace them with
the accessories supplied by our company. Our company shall not be liaible for any direct or
indirect losses caused as a result of accidents for failure to comply with the aforesaid.

The water heater is wall-mounted type.

For ease of installation and removal of water heater, we would recommend that G1/2 loose
joints be installed at appropriate locations on the water inlet and outlet pipes of the water
heater. Determine the position of the hot water supply. Connect the water intake and outlet
pipe together with the water pipe to the positions reserved for use of hot water. Hot water
pipe should preferably not be too long in order to prevent heat loss.

• Power must be switched off before cleaning the water heater.

• 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; chemical solvents (e.g. alcohol) or polish to clean the
water heater.

• 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 intake (take care
not to hurt your hand). If there is water flowing out, the safety valve is working normally.
Please contact the local After-sales Department if no water flows 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 magnesium rod;
change it if consumption becomes excessive.thpaste); acidic substances; chemical solvents
(e.g. alcohol) or polish to clean the water heater.

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 magnesium rod should be regularly replaced. If
maintenance is required, please contact the local Maintenance Department.

If the water heater is not used for an extended period of time, please carry out the following
steps:

Note:Make sure that the wate heater is securely attached to the hook before letting it go;
otherwise it may drop and cause injury or property damage.

Warning!
The water heater must be repaired or maintained by qualified professionals. Improper methods
may cause serious injury or damage to property.

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.
