PLANNING YOUR SOLARMOUNT-I™ INSTALLATION
The installation can be laid out with beams parallel to
the rafters or perpendicular to the rafters. Note that
SolarMount-I™ Beams make excellent straight edges
for doing layouts.
Center the installation area over the structural members
as much as possible.
Leave enough room to safely move around the array
during installation. Some building codes require
minimum clearances around such installations, and the
user should be directed to also check ‘The Code’.
The width of the installation area equals the length of
one module.
The length of the installation area is equal to:
• Thetotalwidthofthemodules,
• Plus1inchforeachspacebetweenmodules(for
mid-clamp),
• Plus3inches(1½inchesforeachpairof
end clamps).
To speed installation, mark beam at approximate
proper foot space before clicking connections to beam.

INSTALLING SOLARMOUNT-I™
Step 1: Attach beam to 2 Flange Connection or 1 Flange Connection
NOTE: Always engage the double-wall side before clicking connection into beam.
NOTE: Do not use connection if the engagement features on the connection are bent, damaged, or obstructed by debris.

NOTE: When installing on pitched roof configurations, locate double-wall section of connection on the downhill side of roof slope.
NOTE: DO NOT re-use flange connections.
Step 2: Attach 2 Flange Connection or 1 Flange Connection to rafter
NOTE: When using 2 Flange Connection w/Butyl Pad, remove liner before installing screws.

NOTEs ON ThErmal ExpaNsiON:
SOLARMOUNT-I is designed to minimize the effects of thermal expansion by allowing the beams to expand and contract independently between con-
nections and attachments. To minimize the effect of thermal expansion, restrict continuous beam lengths to 36 feet or three standard beam lengths.
NOTE ON spliCEs:
Please refer to technical datasheets for recommended distances between splices.
NOTE: Use anti-seize on bolt and tighten nut to 10 foot-pounds.
Step 4A: Install Splices (1) - Use when splicing two beams at a connection.
Splice Bar
NOTE: Tighten nut to 10 foot pounds with anti-seize
Step 4B: Install Splices (2) - Place at least one splice to act as a retaining clip over a flange
connection for every run of beam. This may require field drilling.
