Rheem 12104793 Installation Instructions Manual page 21

Tile Roof: Remove the tiles on the next row above the position of the
collector rail (1) to expose the rafters. Position the collector rail (1) and fix
the collector straps (2) directly to the rafters, using suitable screws or
anchors. Replace the tiles.
Metal Roof: Position the collector rail (1) and fix the collector straps (2) to
the rafters, through the metal roofing material, using suitable screws or
anchors. Care should be taken not to mark Colorbond or other metal roof
sheet with a marking pen and to remove all swarf from the metal roof as
these can cause deterioration of the metal roofing material.
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.
4. Solar Collectors: Using a lifting device, lift the first solar collector (17) onto
the roof and place it carefully with the lower end seated in the collector
rail (1) and prior to positioning the next solar collector, firmly clamp (two
clamps per collector) to the collector rail using the clamps, hex screws,
washers and nuts provided.
Repeat this procedure for additional collectors (17), firmly clamping each
collector to the collector rail (1) with two clamps (13) prior to positioning a
subsequent collector.
"Clamping Collector to Collector Rail"
Refer to
Note: Firmly clamping each solar collector to the collector rail as it is placed
in position reduces the possibly of the collector(s) accidently moving or
sliding off the collector rail.
Remove the red transit plugs from the collector sockets.
5. Collector Unions: Couple the solar collectors (17) together using the
collector unions (3) supplied in the collector kit.
"Coupling Collector to Collector – Conetite Fittings"
Refer to
Note: It will be necessary to loosen the clamps on a collector prior to it being
coupled to its adjacent collector. Secure the clamps again on each collector
after it is coupled to the adjacent collector.
6. Fixing Collector (Bottom): Ensure the solar collectors (17) are correctly
positioned, centred and well seated in the collector rail(s) (1).
Tighten the clamps (13) on each solar collector (17).
