1. Solar Frame: If a solar frame is to be installed, determine the location of the
frame(s). Refer to
instructions provided with the frame(s).
Assemble and fix the frame(s) to the roof in accordance with the installation
instructions provided with the frame.
Depending upon the positioning of the frame on the roof and any minor fall
the roof may have, ensure the collector rail is either horizontal or is higher
on the hot outlet side of the solar collectors. If in doubt use a spirit level.
Proceed to step 4.
2. Solar Collector Location: If a solar frame is not installed, select a suitable
position for the solar collectors. Refer to
page 9.
Collector Rail (bottom) – Pitched Roof Installation: Determine the

location of the bottom collector rail(s) (1). If more than two solar
collectors (17) are installed, locate the collector rail (1) from the Additional
Collector kit adjacent to the first collector rail (1) and join together using the
drive 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 bottom 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 bottom collector rail
(long) (1) and one collector strap (2) to the additional bottom single collector
rail (short) (1) (if used).
"Hooking Collector Strap to Collector Rail"
Refer to
on page 27.
When positioned, the collector rail is to be either horizontal or have a rise
across the solar collectors from the solar cold connection side up to the solar
hot connection side for an open circuit system. The solar hot outlet and hot
sensor connection is to be the highest point of the system.
Note: Refer also to
installation is on a tile roof where the tile has a flat profile. Additional
