After installation, be sure to fill the heater completely with water before switching on the power in the first usage. Children must take bath under the supervision of adult.
In winter of cold area, if the heater is idle for a long period, please pull the handle of safety valve to discharge the water. Otherwise it may freeze inside the water heater and cause damages.
In opening and closing the water valve, do not point the shower head to human body. Otherwise it may hurt by the spraying hot water.
In case the power cord of the water heater is damaged, be sure to have it replaced by after service technicians with special cord offered by the manufacturer.
InstallationBefore Usage
Be sure to have it installed by installation staff of the after service department, or the appointed staff. It adopts
Make four holes with diameter of 12mm and depth 65mm with churn drill on the wall as per the installation dimension drawing. Insert the bolts into the holes. Then lift the water heater, set the
To facilitate the installation and dismantling, it is suggested to add G 1/2' flexible nut at the suitable position of the water inlet and outlet pipe separately. Confirm the position needing water supply. Connect the water inlet/outlet pipe and tap water pipe to the position respectively.
The product adopts the patent "PTO I 0" technology of our company. As long as adopting civil power supply, even if the earthing wire is electrified by mistake, the "PTO I 0" technology still can block the dangerous electricity, and ensure your personal safety. But if you find perceptible current, please pull off the power plug and contact local after service department for maintenance. Do not disassemble by yourself.

Connection and use of safety valve
The safety valve should be connected to the cold water inlet pipe. Please check carefully if the direction is correct after installation. The correct direction of installation is that the arrowhead on the safety valve should point to the water heater.
The original pipeline of the water heater is an organic part of "PTO I 0". Do not remove it by yourself.
Otherwise we will not take responsibility for the injure and loss caused by the safety trouble occurred therefrom.

Please connect the drain hose to the safety valve. Connect one end of the hose to the safety valve vent and the other end to the sewage drain. The hose can be cut short or extended as necessary. The hose shall be installed as inclined downward.
This product should work with the safety valve whose rated pressure is 0.75MPa.
The water may drip from the discharge pipe of the pressure relief device and that this pipe must be left open to the atmosphere. Check safety valve once a month as follow: move the small handle of safety valve, if there's water flowing out, safety valve is normal; if there's no water flow, please contact local
The pressure relief device is to be operated regularly to remove lime deposits and to verify that it is not blocked.

AttentionsBefore Usagein Installation
Please fasten the drain hose to the drain thread of safety valve by twisting (see to Figure 3). Connect the other end of drain hose to the sewer to avoid polluting the room by splashing. When the power is switched on, and the water heater starts operating, there may be some water discharged from the pressure relief hole of safety valve. It is due to the water expansion under heating, and is normal phenomenon. The pressure relief pipe shall communicate with the air directly. Do not block it. The discharged water can be led to the sewer. The drain hose connecting to the safety valve shall be kept downward sloping in installation and in a

CleaningBefore Usageand Maintenance
Be sure to switch off the power supply before cleaning. Use humid cloth with neutral detergent to wipe the shell gently. Do not use petrol and other solvent. Finally wipe it with dry cloth and keep the shell dry.

Before Usage |
Select suitable position on the wall to fix the shower nozzle bearer. Connect the shower nozzle hose to the pipeline. Fasten the mixing valve. Check if there's water leakage at each joint.
Be sure to check and confirm that the tank is filled with water, there's no leakage at each joint and the power supply complies with the stipulation before switching on the power.
Safety precaution:
Do not confuse the water inlet and outlet pipe. The wall bearing the water heater shall be strong enough to endure a weight twice as much as that of water heater filled with water.
If any part is damaged, please contact the local maintenance agent, and have it replaced with our spare part.
UsageBefore Usage
After installation, as the tank is empty in the first usage, be sure to open the faucet water inlet valve and mixing valve. When the tank is filled with water, and the shower nozzle or other water outlet keeps water outputting, please close the mixing valve, check if there's water leakage at each joint, and plug the power plug.
Turn the knob as per the needed water temperature. The mark of knob increases from water inlet temperature to 75°C. You can set heating temperature steplessly. The heating indicator will light on under heating mode. Generally the knob should be set to the highest scale. The water heater can regulate the temperature automatically. The power will be switched off automatically when the set temperature is reached, and will be switched on automatically when the temperature drops to certain level. As it continues heating, you can use hot water as well.
When the tap water inlet pressure arrives or exceeds 0.75MPa, the drain hose of safety valve will discharge large amount of water. It is due to extra high water pressure. Please contact the local after service for disposal.
Heating adjustment can be made flexibly all year round adapting to climate changes. In long- term
