7.
collectors (17) are installed, at the top end of the solar collectors (17) locate
the second collector rail (1) from the Additional Collector kit adjacent to the
first collector rail (1) and join together using the driver cleat (8) supplied in
the Additional Collector kit.
Note: The collector straps (2) are to be fitted to the collector rail(s) (1) before
fixing the straps to the rafters.
Determine which slots in the top collector rail (1) will be used for the collector
straps (2) after locating the rafters and taking note of the rafter spacing.
Hook two collector straps (2) to the first top collector rail (long) (1) and one
collector strap (2) to the additional top single collector rail (short) (1) (if
used).
"Hooking Collector Strap to Collector Rail"
Refer to
on page 27.
Locate the top collector rail(s) (1) against and underneath the top end of the
solar collectors.
8. Fixing Collector (Top): Ensure the solar collectors (17) are correctly
positioned, centred and well seated in the collector rail (1).
Clamp the solar collectors (17) (two clamps per collector) to the collector
rail (1), using the clamps (13), hex screws, washers and nuts provided.
"Clamping Collector to Collector Rail"
Refer to
Fixing Collector Rail (top) – Pitched Roof Installation: Fix the collector
9.
straps (2) to the rafters.
Tile Roof: Remove the tiles on the next row above the position of the top
collector rail (1) to expose the rafters. Once the collector rail (1) is in position,
fix the collector straps (2) directly to the rafters, using suitable screws or
anchors. Replace the tiles.
Metal Roof: Once the collector rail (1) is in position, fix the collector straps (2)
to the rafters, through the metal roofing material, using suitable screws or
anchors. The collector straps (2) may be cut to a length of approximately
100 mm to retain the aesthetics of the installation.
Note: Fixings are to penetrate through the high point in the roof material
profile. AS/NZS 3500.4 states a minimum of three (3) screws 40 mm long
be used per fixing strap. Longer screws or anchors may be required to
achieve a 40 mm minimum embedment into rafters for a metal roof.
Additional screws or anchors may be required.
10. Connector: Fit a connector (10) to the inlet of the solar collector array.
