Product Features Installation Introduction
Product Features

The product uses high-efficient flat collectors fixed on the aluminum frame.
1.Select a suitable position for the solar collectors.
2.Determine the location of the collector rail, and hook the collector straps to the collector rail.
3.Remove the tiles from the place reserved for the collector on the roof, then fix the collector
strap to the rafters, using self-drilling screws or stainless steel nails (or with embedded
expansion bolts).
4.Position the solar collectors in the correct configuration with the lower ends seated in the
collector rail.
5.For multiple solar collector installations, couple the solar collectors together using the
collector unions.
6.Ensure the solar collectors are well seated in the collector rail.
Note：
Ensure the glass on your solar collectors is free of dust, salt spray or any other matter, which
may reduce the effectiveness of the solar collectors. If the collector glass becomes dirty, hose
down or if the solar collectors are accessible, wash the collector glass with water and a soft
brush when the solar collectors are cool.
If your system is for flat roof, please refer to the Exploded View of System for flat

2.Determine the location of the water storage tank.
3.The installers shall follow the instructions in the following assembly sketch map to fit the
tank frame and the tank strap together.
4.Remove the tiles from the place reserved for the water storage tank on the roof, then fix the
tank strap to the rafters, using self-drilling screws or stainless steel nails (or with embedded

Filling the Heat Exchange Jacket(For Indirect System)
Please refer to the following system sketch map.
1.Measure the distances from the collector circulation water inlet to the tank circulation
water outlet, and from the collector circulation water outlet to the tank circulation water
inlet.
2.Prepare corresponding pipe fittings according to the measured dimension, and equipped
with the thermal insulating layer.
3.Connect the collector circulation water inlet and the tank circulation water outlet, as well as
the collector circulation water outlet and the tank circulation water inlet by the prepared
pipe fittings.
Note:
1.Counter slope shall be avoided in the connection of the pipeline.
2.The connection of the pipe fittings shall be correct and tight.
3.The circulation pipe shall be installed in a nice and neat way.
4.If insulation is required, the full length of the solar hot and solar cold pipes MUST BE
insulated. The insulation must be weatherproof and UV resistant.
1.Remove the 0.3MPa safety valve from the water tank. This is the fill level for the
transfer fluid and will allow air to escape during filling.
2.With the aid of a funnel and hose connected to the open service valve, pour water into the
funnel until water flows from the vent of the 0.3MPa safety valve.
3.Close the service valve tap and assembly the 0.3MPa safety valve.
4.Check for leaks at all connections.
5.If no leaks are evident, open the service valve tap, remove the 0.3MPa safety valve and add
in the supplied heat transfer fluid through the funnel. Water will be displaced as the heat
transfer fluid is added. Add a further 500ml of water to flush the heat transfer fluid through
the hose and into the collector.
6.Close the service valve tap, refit the 0.3MPa safety valve and ensure no leaks are present,
then move the hose.
7.The heat transfer fluid lever is to be checked every three(3) years by a competent technician.

(For Indirect System)
Note:
1.The heat transfer fluid is a food grade propylene glycol and is not toxic. However, care must
be taken when handling not to spill or accidentally consume.
2.It is normal that some heat transfer fluid may flow out from the safety valve as the heat
transfer fluid is expanded due to the high solar energy collected.
3.The safety valve should be left open to the atmosphere and its outlet should not be blocked.
The solar storage tank be filled with water before charging the heat transfer fluid with the
closed circuit fluid.
4.The service valve, hose and the funnel are not supplied.
1.Open the cold water inlet valve, and inject water into the water tank through the
outlet.
2.When the air totally exhausts and the water flow is continuous, close the mixing valve and
watch carefully to find out whether the tank is leaking water.
3.Make sure that the cold water inlet is always open while using the water heater.

1.Cut off the power and cold water supply.
2.Disconnect the T/P valve, let water flow out until empty.
Please refer to the
to connect the valves and pipe fittings.
1.Install the temperature and pressure
valve(T/P valve) to the T/P valve joint
of the water tank.
Note：
A T/P valve shall be installed to the tank.
It is normal that some water drops may
flow out from the pressure relief hole as
the water is expanded with heat while
the water temperature in the heater
gets higher.
Continuous leakage of water from the
valve and its drain line may indicate a
problem with the water heater .Failure
to operate the T/P valve easing gear at
least once every six months may
result in the water heater exploding.
The T/P valve should be replaced at
intervals not exceeding 5 years, or
more frequently in areas where there
is a high incidence of water deposits.
2.Install the cold water line, non-return
valve and the stop valve to the cold
water inlet of the tank.

Circuit Connections of water storage tank
Open the adapting plate on the left end of the tank, follow the instructions of the
terminals in the diagram below to correctly wire the cables.
1.Determine the length of the electrical cable according to the distance between the
electrical source and the water tank, and this is the power supply of the electrical heater of
the water tank. A 3x1.5mm cable is needed which is offered by the installers. The cable
shall be polychloroprene sheathed wire (eg: H07RN-F,H05RN-F).
2.Connect respectively L line(red) and N line(blue) of the power cable to the L line and N line
of the terminal block,and the earth wire (yellow and green) shall connect to the earth tag on
the heating element.
3.Make sure to use lug plate to fix the power supply wire. The wiring of PE and L/N lines please
refer to below. The length of PE wire shall be longer than L/N wire, so that the L/N
conductors become taut before the earthing conductor if the cord slips out of the cord
anchorage.
For more information, please refer to the wiring diagram.
