Mounting pole guidelines
The installer is solely responsible for use of the information below.
These are general guidelines for normal installations. The following
variances can affect your installation:
• The required diameter and depth of the hole are dependent
on soil type, which varies by locale. An installation in loose,
sandy soil or clay will require larger, deeper holes and,
therefore, more concrete than an installation in soil of average
density.
• The depth and width of the hole should also be increased in
areas subject to winds in excess of 90 mph, particularly if the
location of the mounting pole is open and unprotected.
• Poles taller than 6 feet above ground require that the depth of
the hole be increased.
If in doubt, consult a professional civil engineer who is familiar with local
soil conditions and wind load requirements.
1. Dig a hole 8 to 12 inches in diameter and 40 to 48 inches
deep. Fill the bottom with 4 inches of gravel.
2. Stand the pipe in the hole. Brace the pole so that it is plumb.
Pour concrete around the pipe, filling the hole to ground
level. Add an inch or two of extra concrete above the hole.
Use a trowel to slope the concrete around the pole.
3. Allow the concrete to set up for at least 24 hours before
installing your PoleSide™ rack.
Assembly
Lay module face down on a suitable surface. Slide the ¼” hex bolts
into the slot on the upper and lower brackets. Center the bolts in the
slot at the same distance as the module mounting holes. Attach the
brackets to the module taking into account the two bumps on the
bracket. Loosely fasten the ¼” nuts to the bolts. Center the upper and
lower brackets with respect to the module and tighten the nuts to
15ft-lbs.
Mount the rack and module to the pole with the u-bolts, clamps, 5⁄16”
washers and nuts.
Ensure the panel is facing south and then tighten the 5⁄16” nuts to 30
ft-lbs.
