Installation instruction

Description of parts

Installing safety valve

Install the safety valve which has a rated pressure of 0.80MPa (its connection is G1/2) into the water inlet 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. 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

the situation (Fig. 3)

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.

Instruction manual

▶ After completion of installation, make sure to turn on the water inlet 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 outlet valve when water flows out from the sprinkler head 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.

Operation

1 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: Slowly turn the knob clockwise to raise the temperature setting. The knob will not continue to turn once it reaches maximum temperature setting. Turn it anticlockwise gradually to reduce the temperature setting. Once the minimum temperature setting is reached, the water heater's power will be cut off if you continue to turn the water temperature knob.

• If the heating indicator light is lit, it means that the water heater is heating.
• If the heating indicator light is off, it means that heating is complete and that the water heating is on standby or cut off.

2 Observe the water temperature indicator for the current water temperature.

3 Water heating will be on standby automatically when the water temperature reaches the set temperature. Once it lowers to certain temperature, power will be automatically connected.
4 Observe the water drainage of the safety valve's pressure-relief hole.

When the water pressure is a 20% 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.

Things to note during use

1 Do not connect the power before filling the inner chamber with water in order to prevent damage to the water heater.
2 Adjust the water temperature to the suitable level before use in order to prevent scalding. 3 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.
4 Do not place inflammable substances such as petrol near the water heater, otherwise it may cause fire.
5 To 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.

Installation method

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 position of the water heater. Based on the measurements indicated in Fig. 2, use impact drill to drill two holes of 12mm in diameter and 65mm in depth. Insert the expandable hooks into the holes and ensure that they are securely fixed. Lift the water heater and slip its wall-mount support onto the expandable hooks (as show in Fig.1). Check to make sure the machine is securely suspended. For accessories such as safety valve, please refer to the "Installation of Safety Valve" (for reference only). Make sure to seal the joints with Teflon tapes to prevent water leakage.

Fig.1

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 inlet 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.

Installation Precautions

When installing the water heater, certain space should be reserved (not less than 250mm from the top and bottom and not less than 700 mm 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 inlet 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^ . The pipes should be closely laid out. The hot water outlet should not 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 fourth 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 inlet and outlet. The safety valve should be installed in the designated position and should not be 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 neutral 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.
Safety reminder: In order to prevent accidents, please 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 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.

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

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 works efficiently, the heating pipe and inner chamber should be cleaned once every three years. Take care not to damage the exterior of the heating pipe or the protective layer on the surface of the inner chamber. Depending on the local water quality and the usage habit, the magnesium rod might need to be regularly changed. 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 inlet pipe (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.

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 sprinkler head soft 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.
