Mounting process

Suggested mounting method 1
Connect hanger bracket (D) to strapping (C), allowing enough length
strapping for the flexible strapping to fit under the roof tile and wrap around
the purlin/truss. Remove roof tiles and position hanger brackets.
The bracket should be secured in place by fixing to the purlin. Fixings (i.e.
screws, bolts, etc.) must be appropriate for the type of timber. Hard woods
and soft woods require particular fixings. Fix the bracket in place as shown
in the next image.
Replace tiles once the bracket is fixed in place as shown in the next image. 2
brackets are required per collector.
The hanger bracket should be positioned on the peak of the tile and not in
the valley. This helps prevent pooling of water and degradation to the
brackets and possible leaks.
The collector is positioned into the collector bracket as demonstrated in the
image above. A slight kick of 25mm from the cold inlet side to the hot outlet
side of the collector is recommended (i.e. cold side lower than hot side by
25mm).
In the case of sheet roofing, as depicted in the following image, a roof screw
can be removed, the strap placed over the existing hole and the roof screw
reinserted thereby securing the strap. In instances of sheet roofs,
appropriate waterproofing needs to be effected to the roof surface after
straps have been secured to the roof material.
The tank cradle (A) is positioned up against the top edge of the collector,
with the foot of the cradle slid underneath the collector.
The collector clamp (B) is fixed to the tank cradle to lock down the top of
the collector as depicted in the next image.
The tank cradles should also be placed on the peak of the roof tile. Once the
tank cradles are in place and the collector clamp fixed in place the geyser
can then be positioned into the cradles as pictured in the next image.
