Pre Assembly for Model STP-LCR/120
Step 1 : Connecting Panel Support Channels
A. Lay two 60” panel support channels end to end with a connector in the middle.
B. Using a connector, bolt the 60” panel support channels together. Tighten the 5/16-18 x 7/8”
hardware (hex bolt, flat
washer, and flange nut) to 144 in-lbs (dry). (Detail G) Repeat with the
remaining set of channel rails and set aside.
Step 2 : Attach Pole ClampAssembly to Pole
A. Slide the pre-assembled pole clamp over the pole, the assembly should rest on the notches on the top
edge of the pole. (Detail A).
B. Loosen the four 1/4" bolts slightly to allow the clamp halves to tighten up on the pole.
C. Orientate brace to face south.
D. Tighten the 8 outside 5/16 flange nuts on the threaded rods evenly, making sure that each nut is
tightened the same amount of turns so the distance between
the clamp halves is the same on each
side of the pole, until the torque setting is reached. 144 in-lbs (dry).
E. Finger tighten the 8 inside 5/16 flange nuts up to the flanges of the clamp halves.
F. Using a long 5/16 box wrench, tighten 5/16 flange nuts, alternating turns from side to side, pulling the
flanges together. (Close or touching, not flattened out).
G. Install 5/16 x 7/8 bolt, flat, and flange nuts in the 4 holes of the clamp halves flange ends. Tighten 5/16
bolts, alternating turns from side to side, pulling the flanges together. (close or touching, not flattened
out) (Detail B).
H. Check the torque of the 8 outside flange nuts, re torque as needed.
I. Torque the four 1/4" bolts on top to 84 in-lbs (dry). (previously loosened slightly)
J. (Optional) caulk the seams on top of pipe clamp to seal preventing rain water entering the pipe.
Step 3: Attach Tilt Plate Mounting Channel
A. Place tilt plate mounting channels on the sides of the pole clamp assembly (Detail C).
B. Install 1/4" bolt, flat and flange nuts 6 places on both sides, tighten to 84 in-lbs (dry). Note: placing
the flange nut in the “closed” side of the wrench to align with the bolt through the cutout will make it
easier to start.(Detail D) Note: Dropped nuts cannot be retrieved very easily.
Step 4: Attach Tilt plates
Attach tilt plates, flanges facing to the outside using 3/8-16 x 1.00 bolts, flats, locks and nuts; position
the tilt plates with the top parallel to the ground (0°). Do not torque at this time, tighten only enough
to hold firmly for next assembly steps. (Detail E).

Step 5: Attach Cross Rails to Tilt Plates.
Attach cross rails to the tilt plates, open sides facing IN, with 3/8-16 x 1.” bolts, locks and flats, nuts.
Cross rails are to be on center across the tilt plates and parallel to each other, Torque to 240 in-lbs
(dry).(Detail F)
Step 6:Attach Panel Supports to Cross Rails
A. Confirm the center to center distance of the mounting holes on the PV modules,
and mark on the cross rails the slots that will match that dimension.
B. Loosely attach panel supports to the cross rails in the slots previously marked with 3/8 x 1.0 bolts,
flats, locks, and nuts.
Step 7: Attach Panels to the supports.
A. Lay PV Modules across the panel supports, adjust spacing between modules and center them all on
the panel supports, attach the modules with 1/4 x 3/4 bolts, flats, locks and nuts, once spacing is
satisfactory, Torque to 84 in-lbs (dry) the 1/4" bolts.Detail G
B. Torque to 20 ft-lbs (dry) the 3/8” bolts connecting the panel supports to the cross rails.
Step 8: Adjust Tilt Angle
Remove the lower two 3/8-16 x 1.0 bolts from the tilt plates and tilt the array to desired angle, the array
tilts in 10° increments from 0° to 60°. Re install 3/8-16 x 1.0 bolts and torque all six 3/8-16 x 1.0 bolts to
20 ft-lbs (dry) Note: to set to 60° one bolt set will need to be in the center position

Foundation Hole Guidelines (see charts pages 9,10)
The suggestions below are recommendations only. It is the installer’s responsibility to validate
foundation parameters prior to installation, as local geotechnical report may be required to assess
ground conditions. We recommend consulting with a local engineer familiar with local regulations and
build site requirements, including soil conditions, terrain and load criteria (wind, snow, seismic). All of
these parameters may impact foundation requirements.
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
pipe(s) from touching the base of the hole, insuring complete encapsulation of the pipe when
concrete is poured, as well as allowing for water drainage. (see option 1)
4. The pipe(s) should be installed vertically no matter the slope of the install site and centered in
the hole.
5. Make arrangements to prevent the pipe(s) from twisting or moving prior to and during
pouring of the concrete.
6. The pipe(s) 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 pipe until the concrete has reached
3,500 psi.
The Steel Post shall 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 post embedment shall be a minimum of 36” into the concrete pier
with (2) #5 bars extending vertically to within 12” of the bottom of the pier, one
on each side of the steel post. The rebar shall lap with the steel post a minimum
of 30”. A bolt (5/16” minimum) shall be placed through the steel post at
approximately 6” (+/- 2”) from the bottom of the post with a hand tightened nut
to provide uplift resistance in direct bearing with the concrete

Installer Responsibility
The installer is solely responsible for:
i. Complying with all applicable local or national building codes, including any that may supersede this manual;
ii. Ensuring that Tamarack Solar and other products are appropriate for the particular installation and the
installation environment;
iii. Using only Tamarack Solar parts and installer-supplied parts as specified by Tamarack Solar. Substitution
parts may void the warranty;
iv. Ensuring safe installation of all electrical aspects of the PV array; and
v. Ensuring correct and appropriate design parameters are used in determining the design loading used for the
specific installation. Parameters, such as snow loading, wind speed, exposure and topographic factor should
be confirmed with the local building official or a licensed professional engineer.
Warranty Information
Tamarack Solar warrants each Mounting Structure to be free from defects in materials and workmanship for ten (10)
years from the date of first purchase (“Warranty Period”), when installed properly and used for the purpose for which it is
designed, except for the finish, which shall be free from visible peeling, or cracking or chalking under normal atmospheric
conditions for a period of three (3) years, from the earlier of 1) the date the installation of the Product is completed, or 2)
30 days after the purchase of the Product by the original Purchaser (“Finish Warranty”). The Finish Warranty does not
apply to any foreign residue deposited on the finish.
Galvanized coated sheet steel components will show rust on cut edges and is normal and will not affect the structure
and function of the mount.
All installations in corrosive atmospheric conditions are excluded. The Finish Warranty is VOID if the practices specified
by AAMA 609 & 610-02 – “Cleaning and Maintenance for Architecturally Finished Aluminum” (www.aamanet.org) are not
followed by Purchaser for Tamarack Solar’s aluminum based products.
The warranty covers the replacement cost of parts to repair the product to proper working condition. Transportation and
incidental costs associated with warranty items are not reimbursable. The warranty does not cover normal wear, or
damage resulting from misuse, abuse, improper installation, negligence, or accident, or typographical errors in instruction
manuals. The Warranty does not cover any defect that has not been reported in writing to Tamarack Solar within ten (10)
days after discovery of such defect. Furthermore, it does not cover units that have been altered, modified or repaired
without written authorization from the manufacturer or its authorized representative, or units used in a manner or for a
