Tamarack Solar LTP HW Mount Series Installation Manual page 26

Installation Recommendations: Concrete to be min 3,500 PSI
1. Auger hole to minimum depth shown in foundation guidelines, + 6" for (#2). Drilled holes to be filled
with concrete shall be cleaned to remove all loose cuttings.
2. Stumps or other decomposable material exceeding 3 inches in the least dimension located within the
drilled diameter of the foundation shall be removed entirely prior to placing concrete.
3. The bottom 6" of hole should be filled with crushed rock or a blocking; this will prevent the pole from
touching the base of the hole, ensuring complete encapsulation of the pole when concrete is poured,
as well as allowing for water drainage. (see option 1)
4. The pole should be installed vertically no matter the slope of the install site and centered in the hole.
5. Make arrangements to prevent the pole from twisting or moving prior to and during pouring of the
concrete.
6. The pole should be braced to remain plumb and in position until concrete has cured at least 24hrs.
7. The solar system shall not be attached to the support pole until the concrete has reached 3,500 psi.
The Steel Pole be embedded into the concrete pier using one of the following options:
A. Option 1: To within 12” of the bottom of the concrete pier.
B. Option 2: The steel pole embedment shall be a minimum of 36” into the concrete pier with two #5 rebars
extending vertically to within 12” of the bottom of the pier, one on each side of the steel pole.
The rebar shall lap with the steel pole a minimum of 30”. A bolt (5/16” minimum) shall be placed
through the steel pole at approximately 6” (+/ 2”) from the bottom of the pole with a hand
tightened nut to provide uplift resistance in direct bearing with the concrete.
