Installation
Installment of water-storing tank
Water storing tank equipped for water heater is a standing tank. Based on
customers' requests, ensure specific installment position, and place water-
storing tank. Connection opening of water-storing tank faces one side of the
pipeline, and then all corresponding parts of each connection opening should
be connected. Layout of water tank should be perfected in installing.
Installment of water pump
To connect the the water inlet of pump to circulating water-exiting opening
and the dirrection must be right.pay attention that the connection of water
pump must be firm. Power of water pump should be adjusted to the third
grade, and it is prohibited to put other articles on water pump.To avoid that
water spurts out to the pump,or the result is serious.
Connection of pipeline
To measure the distance between water inlet of collector equipment and
water pump as well as that between water-exiting of collector equipment and
circulating entrance of water-storing tank. To cut pipes according to the
measured size, to cover the heat preservation layer, and to connect collector
equipment, water pump and water-storing tank. Pay attention that the
connection of circulating pipeline should avoid the opposite alternative. The
connection of pipe parts should be proper and firm, and the heat preservation
materials should be covered perfectly. Pay attention that the probe of the
sensor is placed properly. Installment of pipeline should be artistic and neat.
Connection of collector equipment and water-storing tank
After the collector equipment is fixed, one end of the equipment should be
joined to the tee joint, and the top hole of the tee joint should be connected to
an automatic exhausting valve and the bottom hole should be connected to
the water- exiting pipe. The Water-exiting pipe should be connected to
circulating entrance of water-storing tank,the oherside of the collector
equipment should be connected to circulating exit of of water-storing tank.
Pay attention that connection of circulating pipeline is proper and firm and
that the heat-preservation materials are covered perfectly.
Installment of other accessories
Connection of Single direction valve Fix the single direction valve on the
Water-exiting pipe of the collector equipment,the direction of the single
direction valve and the direction of the Water-exiting pipe must keep same,
please see Fig.1- Fig.2.
Connection and Use of Safety Valve
after switching on the water heater, a
little water will drip from the safety valve pressure relief vent due to normal
expansion. The vent shall always keep open to the air. Avoid being blocked.

1.Function introduction of controlling board
There are five icons on the indication screen, among which are the following four
icons: solar energy, simultaneous heating, preset, and intellectual power. They
respectively represent the four modes of the system working, that is solar
energy heating mode, simultaneous heating mode, preset heating mode and
intellectual heating mode. And the water pump icon is used to prove that water
pump is in a condition of full speed circulated running. For the indication board,
see Figure 5.
For details, see the following:
---When the green point in the icon is on, it tells that the system is in the solar
energy heating mode.
(Double color)---when the green point in the icon is on, it tells that the system
is in the simultaneous heating. When the red light is glistening, it tells that the
ystem in electrical heating and when it reaches the mounted temperature, it will
automatically leap to the solar energy heating mode.
(Double color)--- when the green point in the icon is on, it tells that the system
is in the preset heating mode. When the red light is glistening, itmounted tells
that the system in electrical heating and when it mounted reaches the
temperature, the green point will be on constantly.
(Double color)--- when the green point in the icon is on, it tells that the system
is in the intellectual heating mode. When the red light is glistening, it tells that
the system in electrical heating and when it reaches the temperature, the green
point will be on constantly.
--- Arrows on the icon are in proper order with counter hour hand. When the
green point is on, it tells that the water pump is in 100% full speed running
condition.
Temperature indication icon for tank--- when the character is on, it tells that
the present indication temperature is water temperature of the tank.
Temperature indication icon for collector equipment--- when the character is
on, it tells that the present indication temperature is the water-exiting
temperature of collector equipment.
2. introduction of basic working mode
A. Solar energy heating: this function adopts the temperature difference
between water-exiting temperature of collector equipment and that of water-
storing tank to control the running of water pump. It transfers solar energy
absorbed by collector equipment to hot water in water-storing tank for
For the first use after installation, due to there's no water within the tank, first the
cold water inlet valve and mixing valve must be opened. Close the mixing valve
when water flows out continuously from the showerhead or other outlets (the
tank is full). Check connections are free of water leakage, and insert the power
plug.
