automatically heat to set temperature and stop heating when up to set temperature.
Note: if the actual water temperature is less than the set temperature after getting at the
preset time, the system will automatically prolong the heating time for another 30 minutes,
and will stop heating after 30 minutes no matter whether the set temperature is obtained.
If the actual temperature is up to the set temperature before the preset time and the preset
time is still not up after the actual temperature is decreased by 5℃, the heater will perform
heating again, and stop heating after arrival of preset time no matter whether the set
temperature is obtained.
For example: preset bath time is set to be 18:30, the temperature is 70℃ and power is
2.0Kw. (As shown in Figure 9)
Do not set it at a place too cold; it may freeze.
Do not use as floorstanding appliances.

Installation must be made by installers of or designated by our company after-service
department. The water heater shall be wall-mounted.
Make 2 holesφ12mm, 65mm deep in wall with an impact drill according to installation
dimension. Insert and fix expansion hooks in corresponding wall holes. Lift the water heater.
Make wall rack correspond to the hooks. Hang the ring of extended connection line onto a
hook and hand the wall rack (see Figure 2). Install accessories such as safety valve as shown
in Figure 3. Use sealing compound to prevent water leakage.
To facilitate installation and removal, it is suggested a G1/2” movable nut is fitted at
appropriate locations on inlet and outlet pipes respectively. Find the location requiring hot
water supply. Connect inlet pipe, outlet pipe and city water pipe respectively to the use point
for hot water.
Note: The hot water pipe shall not be too long to reduce the heat losses.
Please reserve some space in installation for the future maintenance.
Connection and use of safety valve:
The safety valve should be connected to the 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 for fear of indoor contamination. The hose
can be cut short or extended as necessary. The hose shall be installed as inclined downward.
The heater should work with the safety valve whose rated pressure is 0.80MPa. When the tap
water pressure is no less than 0.80MPa, a large amount of water may flow out from the drain
hose of the safety valve, which indicates water pressure is overly high and after-service
department shall be notified for a solution.

Please fasten the drain hose to the pressure relief hole of
safety valve by twisting (see to Figure 4). 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 the 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 drain
hose connecting to safety valve shall be kept downward
sloping in installation and in a frost-free environment.
Safety precautions:
1. Do not confuse the water inlet and outlet pipes. The water bearing the water heater shall be
strong enough to endure a weight twice as much as that of water heater filled with water. Do
not secure it by means of adhesive or similar products because the fixation by such methods
is unreliable.
2. To avoid danger caused by accidental reset of heating breaker, the power for the heater
cannot be supplied by timer and other external switch devices or connected to circuit with
frequent switching for facility use.
3. If any part is damaged, please contact the local maintenance agent and have it replaced with
our spare part.
4. Tap water inlet pressure shall be no less than 0.05MPa and the maximum pressure shall not
exceed 0.75MPa.
Connect to drain hose
(Figure 4)
During heating, water may drip from the drain hose of the pressure relief hole due to
expansion and the hole must be left open to the atmosphere. Check safety valve once a
month as follows: move the small handle of safety valve, if there is water flowing out, safety
valve is normal; if there is no water flow, please contact local after-sales service station.
The pressure relief hole is to be operated regularly to remove lime deposits and to verify that it
is not blocked.
