(or Two Vertical) Collector Arrangement.

Procedure:
1. Choose attachment site, allowing for subsequent pipe
penetration.
2. Bolt the support base (SE60-108), support riser (SE60-110) and
transverse support (S101 collector rail) together to form a triangle
truss, as shown in
Figure 17.
3. Bolt the resulting truss(es) to the upper and lower profile (frame)
rails.
4. If installing one collector, the triangle trusses must be set up at
intervals of ≤ 82 in. (210 cm) for horizontal installation or ≤ 43 in.
(110 cm) for vertical installation.

5. If installing two or more collectors, the triangle trusses are to be
positioned at the midpoint, behind the collectors.
6. Whenever two or more triangle trusses are installed, brace the
center span with a cross-brace, as shown in
Figure 17.
7. When installing four or five trusses, brace both end spans with
crossbraces, as shown in
Figure 18. For six or more trusses, cross-
braces should also be placed in an inside span.

8. If multiple flat-roof mounting frames are being set up next to
one another, use frame connector (splice) kits (SFC001, shown in
Figure 19) to join them, as shown in Figures 18 and 20. Line up the
mounting supports with a string so that the mounting frames will be
aligned properly.
9. Fasten the flat-roof mounting racks to the roof in an appropriate
manner, or weight them down with at least 400 lbs. (180 kg) of solid,
dead weight (e.g. concrete slab) per collector if the installed height
is less than 25 ft (8 m). Remember to take the static and dynamic
(e.g., wind) loading into account for the roof structure.
10. For installed heights above 25 ft. (8 m), weighting is not
advisable due to the higher wind loading conditions. In this case,
the holes in the horizontal support base (SE60-108, or SE60-110 if
flipped for 30 degree tilt) should be used to fasten the mounting
hardware to the roof (six M6 bolts per horizontal support).
