To ensure that customers can use water heater properly and safely, we here
seriously inform our customers that you must contact the appointed
professional serving personnel for installing and service. For any improper
installment, our company will not burden any responsibility.
When the power supply is connected, the pump is electrified;Pay attention
that connecting lines of pump are inserted stably, and can not load emptily.
Before any maintenance and repair of water heater, please make sure that
you cut off other power Supply. Non-professional persons are not allowed to
adjust and maintain water supply.
Before electrification please make sure that machines are full with water,
otherwise it will cause a system malfunction. Please make sure that the
sockets are subject to national standards and are connected to the ground
reliably. It is prohibited to use water heater without a reliable grounding.
The water heater is equipped with safety valves. for secure use, please do
not change installment position personally. The evacuating tube nozzle
should be downwards vertically and are open to the air so as to prohibit
jamming the exit. A draining pipe is linked to the evacuating tube nozzle and
leads to the sewer opening. (the draining pipe is otherwise sold)
Hot water with a temperature higher than 50
might result in scalding and
customers should mix hot water and cold water and then have a shower or
wash.
In cases when water heater is seriously soaked, it must be checked by
technical personnel ratified by our company before it is reused.
The hot water in water heater is not suitable for drinking. As a result of long-
term use, scale might be produced in the water tank. Meanwhile, the aging of
the water pipe can result in a change of water quality. Therefore, when you
wash rice and vegetables with water in the container, please wash them once
again with clean tap water.
When collector equipment is installed, it can not be inversely placed.
Outdoor pipeline must use metal pipes.
Heat-preserving of pipelines must use specially designed materials by our
company.
ollector equipment should be installed facing south.
Evacuating opening of the system safety valve should be connected to the
release opening of sewage.
All parts of the whole system are not allowed to be disconnected personally
otherwise, results should be burdened personally.

Particular warning Attentions in installment
heats ahead according to the preset 65 before the first heating period
arrives the second day. In cases when the machine is turned on, press the
when the machine is turned on, press the mode key continually to enter
intellectual heating mode. The green point in the working indication icon is on.
When the electrical heating starts, the red point in the icon glistens. And when
the electrical heating is over, the green point is constantly on. Press the
setting mode and you can set the heating temperature, whose scope is 30
-
75 . Note: in this mode, the solar energy heating is not concerned.
3.introduction of other functions
A.the system has a function of electricity-loss memory and that of automatic
starting when electrified.
B.high temperature protection: in the process of the water pump running, when
the water temperature of water-storing tank exceeds the high-temperature
protection temperature (85
) set by the system, the water pump will
automatically stop running .
C.low temperature protection: when the water exiting temperature is lower than
the low temperature protection temperature (4 ) set by the system, the water
pump will automatically start running at full speed. And when the temperature
rises to 7
, the water pump will stop running.
D.malfunction protection: this system has circuit malfunction alarm (E1),high
temperature alarm (E2), sensor malfunction alarm of collector equipment(E3),
sensor malfunction alarm of water-storing tank (E4), as well as pipeline
leakage and water pump empty running alarm (E5), etc. When these problems
happen, the system will display malfunction code E1~E5. The above
malfunction protection is non-restorable and therefore, the system can only
normally run after malfunction is eliminated and the electricity is reconnected
4.interface indication and instruction for operation
After the solar water heater center is installed, to confirm that the water-
storing tank is full with water and to check that each pipeline is connected
properly and not leaking. To check that the power supply of the water-storing
tank corresponds to the requirements and then to connect power supply.
5. Instruction for controller
A.turning on/ turning off: the system is turned on directly and automatically
enters the working mode and conditions before power supply is cut off. The
first tacitly approved working mode of the system is the solar heating mode.
The four-number tube of the indication screen displays the clock. The five-
number tube under the screen respectively displays water temperature of
water-storing tank and the temperature of water exiting. The indication
interface is displayed in Fig. 6 and at this time, all the pressing keys are
effective. Then press power supply key and the system will be turned off and
enter the electricity saving mode. The indication interface is displayed in
