Locating Roof Rafters
✍
❏
Locate the rafters directly under the solar collectors,
and at least 8" from the ends of the solar collectors.
In the case of 4' x 8' solar collectors and 24" rafter
spacing, the clips should be mounted six feet apart
(that is, one foot from the edge of the collector).
❏
To find the center of the rafters, lift the shingle and
use small nails to find the two edges of the rafter.
❏
Drill a 1/4" pilot hole in the rafter for each of the
front mounting clips.
Flush Mounting Micro-Flo® Solar Collectors
✍
❏
Fill the holes with silicon sealant and secure the two
front clips to the roof using lag bolts. Seal the
perimeter of each mounting clip base with silicon.
❏
Take the A solar collector and slide two 3/8" bolts in
the bolt track.
❏
Loosely fasten these bolts to the bottom hole of the
front mounting clips using a lock washer and nut.
❏
Center the solar collector so that the spacing from
the end of the solar collector to the mounting clip is
equal on both ends. The solar collector ports must
be on the right hand corner of the solar collector
when, viewed from below.
Optional Second Solar Collector
✍
❏
If you have a two solar collector system, place the
B solar collector above the A solar collector. Make
sure that the ports are on the right hand side.
❏
Using the aluminum channel, fasten collector B to
A as shown in the figure.
❏
Fasten the upper mounting clips (not shown) to
the top of the collector(s), and use lag bolts to
secure them to the rafters in the same manner as
for solar collector A.
❏
Tighten all nuts that secure the collector(s) to the
mounting clips.
