3.0 Installation Instructions
3.1 Installing the SV30AWX Solar Collector
Please follow the general installation instructions for the SV30. These instructions come in three versions which are
all included:
SV30AX on roof type 1 (fibre cement, tile etc. Type of roof with overlapping plates or similar)
SV30AX on roof type 2 (asphalt or steel plates. Type of roof with no overlapping)
If placed on the wall the SV30AWX should have an angel of 40 - 60 degrees from horizontal (the smaller angel the
more warm water in summer - and less warm air in winter)
3.1.1 Drilling holes in the roof
One hole Ø = 20 mm is made for the cold piping to the SV30AWX solar collector. This hole is made next to the lowest
pipe outlet on the collector. (For type 1, take care always to drill in crests!)
A second hole Ø = 20 mm for the hot piping from the collector is made next to the first. (See page 7)
Before drilling make sure that the position is correct.
A rubber lead-in will secure the watertight lead-in of the 16 mm tube through the roof plate.
3.2 Piping and Insulation
1)
16 mm tube (smooth tube for distances over 12 m) is insulated and fixed. Fasten the tubes with strips or wire
to laths at short invervals to avoid bends.
2)
Intense heating may result in linear expansion especially in rib tubes, but smooth tubes will also expand to
some degree. Normally, this causes no problems. However, care should be taken to prevent the pipes from
rubbing on sharp edges or the like.

Long piping arrangement on the roof
If it is necessary to lay tubes outside on a roof etc., the insulation must be protected by a wind and weather proof
tube. This kind of tube comes in 25, 39, 48 and 63 mm Ø and can be pulled over the insulation.
Note: The wire on the roof is secured from birds by pulling it through the rib tube
3.3 Roof lead-in
Roof penetration
The rubber let in is put directly in a 19-20 mm hole in the
top of the roof. The 16 mm tube may be pulled through
this. Use some soap so that it will slide through.
25 mm rib tube or
insolation protects
the 16 mm tube
16 mm PP tube
