2. Cautions

2.1 Collector’s glazing for toughened glass, please be careful handling, when installation,

please pay special attention to don’t impact, Be careful to be scratched when glass

broken,

2.2 Under no circumstances are the collector to be left exposed to the sun over a long

period before the system installation was completed. Avoid high temperature of empty

collector to affect system efficiency,

2.3 Please shadow the collector without heat extraction from the system,

2.4 Please clean up snow in time to get full energy absorb,

2.5 The angle of installation must during 25°～90°.

Maintenance requirements ：

Disassembly：Prize the A(decoration strip) firstly and then use a pistol to dig into to take out B(Aluminum

rivetφ3.2×11 ) and finally move glass(together with glass frame)

Assembly：Put on the glass((together with glass frame)，Note the sealing strip should be inside of

troug.And then make rivet to fix it and finally tighten decoration strip.

4. Installation

Please select the roof which is faced the sun mostly,

installation Angle should be identical with local latitude,

Roof load shall withstand collector weight,

Make sure no cover around installation area.

Installation is divided into：

4.1 Slope roof on tile 4.2 Flat roof： 4.3 Color-coated steel tile

installation

4.1 Slope Roof Installation

Please install according to the roof angle, local latitude and the form of tile

Installation Process：

4.1.1 Fix stands installation：

4.1.1.1 Please remove the tiles

according to the “A”、“B”、“C”size,

and fix the brace to the roof

（Please choose the different fix

ways according to the roof

material---wooden screws or

anchors）

4.1.1.2 Please put the bottom of screw to tracks of horizontal bar and fix with the brace

(same as below photo)

4.1.2 horizontal bar installation：

Please fix the horizontal bar to well-installed brace,

make the difference of the top and down horizontal

bar。See below photo.

（It is better to add rubber spacer below horizontal bar

to keep roof smoothly）

4.1.3 Collector installation

Put the collector to the tracks of horizontal bar

Make the side of collector tighten with the fixing。

4.3 Color-coated steel tile installation

4.3.1 Fix the horizontal bar installation

Please install the horizontal bar to the color-coated steel tile, fasten with the tapping screw,;

see below photo: the screw distance between horizontal bar is 1000mm

Above shows 2sets solar collector in series;

The horizontal bar size should be 2200mm when 2pcs solar collector in series;

The horizontal bar size should be 3200mm when 3pcs solar collector in series;

(3pcs solar collector in series install in flat roof, you should increasing 1pcs front leg,

1pcs stands higher,1 pcs stands lower,1pcs slope track ,2pcs X-Bar )

Note: Fix the feet tightly with bolts after the complete assembly.

5. Connection and Lightning-Protection

5.1 Connection and Lightning-Protection:

Max number of collector in series: 10units

Mark：Please make sure the effective grounding to prevent lightning.

6.2 Double Coils System

Double coils in the storage water tank, below coil acts as heat exchanger to get

energy from the solar collectors to heat water, upper coil acts as heat exchanger

from other normal heating solutions like Gas/Oil boiler etc.
