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
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.
Installation Precautions
The water heater is a
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
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.
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.
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.

Connection and use of 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 flow from the safety valve’s
pressure relief hole due to the expansion of water in the heater. The
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.

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
Inspect all connections to ensure that there is not water leakage before connecting to power.
Cleaning and Maintenance
Warning!
The water heater must be repaired or maintained by qualified professionals. Improper methods may cause serious injury or damage to property.
Note : Before calling service technicians, please refer to the Q&A to solve simple issue.
Operation
1Adjust 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

Cleaning
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, 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 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
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.
2When the water temperature reaches the set temperature, it will enter
thermal state.Once it lowers to certain temperature, power will be automatically connected.
3Observe the water drainage of the safety valve's

Things to note during use
1Do not connect the power before filling the inner chamber with water in order to prevent damage to the water heater.
2Adjust the water temperature to the suitable level before use in order to prevent scalding.
3Insofar 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.
5To avoid danger caused by accidental resetting of the heating breaker, the power for the heat cannot be supplied by timer and other external switch devices or connected to circuit with frequent switching for facility use.

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.
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
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.
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
2Screw the water drainage pipe to the safety valve's
3Turn 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 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.
