preferred).
Do not confuse inlet and outlet water pipes. Safety valve shall be installed at designated
position with no random modi cation.
Operation Instructions
Before Usage
For the rst use after installation, due to there's no water within the tank, rst the city water
inlet valve and mixing valve must be opened. Close the mixing valve when water ows out
continuously from the showerhead or other outlets (the tank is full). Check connections are
free of water leakage, and connect power.
Turn the knob to set your desired water heating temperature, which can be stepless changed
between cold water inlet temperature and 75°C. In heating mode, heating lamp is lighted on.
Normally the knob shall be positioned at highest temperature. This machine has a thermostat
function, which automatically switches o the water heater when temperature reaches the
setting value, and switch on again when water temperature decreases to certain value.
City water pressure ≥ 0.80MPa will cause much water owing out from safety valve pressure
relief vent. This is due to too high water pressure. Please ask after-sales service for correction.
Attentions in Operation
Before Usage
1
To avoid causing machine troubles, do not connect power before tank is full of water.
2

Installation
Before Usage
Installation must be made by installers of or designated by our company after-service
department. The water heatershall be wall-mounted.
If there is no power cord or plug and the power is not interrupted, the xing line connected must
be equipped with the all-pole disconnection device provided by breakaway contact under the
overvoltage type III condition according to wiring rules.
Before installation, make sure water heater rear wires are t rmly. Determine an installation
location. Make four holes ∅12mm, 65mm deep in the wall with an impact drill according to
installating dimension. Insert x expansion hooks and expansion bolts in corresponding wall
holes. Lift the water heater. Insert wall rack onto the hooks and bolts. Fit at washers, rear wires
and nuts in turn onto the bolts (see Figure 2). Tighten the nuts and check them rm. Install
accessories such as safety valve, drain hose as shown in Figure 3. Use sealing compound to
prevent water leakage.
To facilitate installation and removal, it is suggested a G 1/2" movable nut is tted at appropriate
locations on inlet and outlet pipes respectively. Find water supply location. Connect inlet pipe,
outlet pipe and city water pipe respectively to the use point.
The hot water pipe shall not be too long to reduce the heat losses.
Please reserve some space in installation for the future maintenance.

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.
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. (see to Figure 4)
The water may drip from the discharge pipe of the pressure relied
device and that this pipe must be installed in a continuously downward
direction and in a frost-free environment. Check safety valve once a
month as follow: move the small handle of safety valve, if there's water
owing out, safety valve is normal; if there's no water ow, please
contact local after-sales service station.
The pressure relief device is to be operated regularly to remove lime
deposits and to verify that it is not blocked.
