Cleaning
External cleaning
•
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.
Internal cleaning
In order to ensure that the water heater will work with high effi ciency, 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.
Check
•
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 fl owing out, the safety valve is working normally. Please
contact the local After-sales Department if no water fl ows out. In the event of damage to the
safety valve, please replace it with a safety valve of similar specifi cations.
•
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.
Not in use for an extended period of time
If the water heater is not used for an extended period of time, please carry out the following steps:
1 Turn off the water pipe valve.
2 Screw the water drainage pipe to the safety valve's pressure-relief hole; turn on the safety
valve handle.
3
Turn the hot water valve to the maximum (at the same time unscrew the soft sprinkler pipe from
the water outlet valve; take care not be scalded by hot water), drain the inner chamber of water.
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 fi re 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 fi ll the inner chamber with water before use.

Installing safety valve
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 water will fl ow 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.
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.

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.
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 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 four times
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
fl oor 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 fi lled with water and that there is no wa-
ter leakage. The power supply should also conform with requirements.
Safety reminder: In order to prevent accidents, please use our compan
y'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.
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.
The water heater is wall-mounted type.
Determine the installation location of the water heater and drill 4 holes of 12mm and 65mm
deep in the wall with a churn drill. Insert the expansion hooks and expansion bolts into
corresponding holes and fasten them. Then, lift the water heater to put the hangers on the
hooks and bolts. Mount the flat shims, connecting wires on the back of the water heater and
nuts on the bolts in turn (as shown in Fig. 1) and fasten the nut. Then, check if they are firm.
Refer to “Install relief valve" to install the relief valve and other accessories (only for installation
reference). Remember to use Teflon tape to avoid leakage.
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.
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.
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-fl ow valve when water fl ows out from the
sprinkler or the water outlet (indicating that the container is fi lled with water). Turn off the
water outlet valve. Inspect all connections to ensure that there is not water leakage before connecting to power.
