HOOKING COLLECTOR / TANK STRAP TO COLLECTOR RAIL
1. If three solar collectors are to be installed, locate the additional collector rail adjacent to the first collector rail and join
together using the drive cleat supplied in the parts kit (refer to
Detail B ).
2. Determine which slots in the collector rail will be used for the roof straps after locating the rafters and taking note of
the rafter spacing.
Note: The roof straps are to be fitted to the collector rail(s) before fixing the straps to the rafters.
