Attentions in installment
Electric controller
should be far from strong interfering sources.
Tne-way pipeline between water-storing tank and collector equipment must
be less than 10 meters.
Sensor of collector equipment should be installed at the water exiting
Opening.
The exhaust valve should be installed vertically at the water exiting opening
of collector equipment and its position in the pipeline should be kept the
highest. To screw loosely the exhaust cap after installment to make it
exhaust freely.
Pay attention the crossing corner of water entering and exiting opening
should be connected and the bottom one is for water-entering and the top
one is for water exiting in the installment of collector equipment with flat
board
.
Installation
Installment of solar water heater is composed by the following parts:
installment of collector equipment, installment of water-storing tank and
installment of water pump. Installment of each part should be completed by
the professional installing personnel appointed by our company in order to
ensure good functioning of the system.
Installment of collector equipment
Collector equipment of solar water heater is installed with the method of
oblique top. collector equipment is placed on the southern rooftop of the
house so as to ensure that the equipment faces south and there is no shelter
ahead. All the four corners of each collector equipment are linked perfectly
with steel wire rope. the other end of the steel wire rope is fixed under eaves
or on the wallwith a expanding bolt. Pay attention that the steel wire rope is
strained and the expanding bolt is beaten firmly. Take the installment of solar
water heater of PJF1-80/100W as an example. For the sketch map of
installment, please see Fig.3.

then the system will delay at most half an hour for heating.
D. Intellectual heating: this function automatically classifies and analyzes the
latest seven-day bathing regularity and memorizes the period of time that
customers have a bath most frequently within the seven days. And it then
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
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.
2. Introduction of other functions
A. The system has a function of electricity-loss memory and that of automat -ic
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 and will display the malfunction code E2.
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 re-
connected.
3. 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.
4. Instruction for controller setting
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 energy mode.
The four-number tube of the indication screen displays the clock. The five-
