Installation Manual
ECO 101-2546 07/20/2011 3-CMLT-1032 REV C
In all cases the system should be mounted as solidly as possible to the most rigid
part of the structure.
An option on some structures is to mount the pole from inside the attic (refer to “Attic
Mounting” on page 8). The pole will then protrude through a hole in the roof (optional roof
seals are available for this purpose). For this type of installation mounting two 2x4 or 2x6
boards across the rafters or trusses is recommended for the mounting of the isolators (see
drawing on page 8). If the pole is mounted and there is some time delay before the turbine
is installed, be sure to cover or plug the top of the pole so that moisture does not enter
through it.
Pole and Hardware Selection
The pole for mounting an “AIR” wind turbine must be 1.875” to 1.9” (48 mm) outside
diameter. This is the actual diameter of 1 ½” schedule 20 or 40 pipe. The material should
be Aluminum of at least 1/8” wall thickness, or steel of at least 1/16” wall thickness. The kit
is designed for use with .065 in. (1.65 mm) wall thickness fence post tubing, which is
lightweight and economical. If heavier pipe must be used, the total pipe length must be kept
under 8 feet or additional isolators will be needed to help support the extra weight.
A good source of pipe or tubing for the pole is your local fence supply company, where this
tubing is commonly used for chain link fence posts. If you determine the length of tubing
needed for your application ahead of time, the fence supply company will usually sell what
you need cut to length. Make sure the ends are smooth and free of burrs so that the turbine
wires can not be damaged or cut by the tubing. This may require de-burring the tubing with
a file after it is cut.
The hardware you will need to mount your kit will depend on the type and thickness of
siding used on your structure. For a typical wood frame structure with in ch (13 mm)
siding, it is recommended that mounting boards over at least two studs be installed using
either 3” (75 mm) long lag bolts and washers or wood screws fastening the boards to each
stud. ” bolts (lag or through) with washers should then be used to mount the isolators to
the mounting boards.
If only a single wall stud is available for mounting, plywood blocks at least 1” (25 mm) thick
and 12” (300 mm) square should be mounted to the stud with at least two 3” (75mm) long x
3/8” diameter lag bolts and washers. The isolators should be mounted to the blocks with ”
bolts (lag or through) and washers. In the case of brick or concrete walls, expansion bolts
may be used to attach the pole to the wall, although bolting through the wall is preferred.
Site Preparation

It is recommended that 2x4 or 2x6 mounting boards be used. This option allows the
most flexibility as to where the turbine will be mounted and gives the best mounting
surface. They should be mounted directly to wall studs at both of their ends and to each
stud available along their length. Once installed, the roof mount kit can be placed
anywhere along their length.
If only a single wall stud is available for mounting, plywood blocks at least 1” (25 mm) thick
and 12” (300 mm) square should be centered on the stud and mounted with 3” (75mm) long
lag bolts and washers. The mounts should be centered on these blocks.
Assemble a mount with its base plate and two isolators. Hold the assembled unit in the
desired position for the upper mount and mark the hole locations for the 2 isolator mounting.
Repeat this process for the lower mount location using a plumb-bob to assure vertical
alignment. Drill holes appropriate for the hardware to be used on these marks.
Pole Mounting
Mount the isolators to the holes, which were drilled in “Site Preparation”, on page 7.
Slip the plastic clamp inserts onto your pole and slide them into the approximate mounting
locations on the pole. Make sure the ends of the pole are smooth and burr free before
mounting so that the turbine wires cannot be damaged or cut by the end of the tubing. This
may require dressing the tubing with a file after it is cut.
Assemble the clamp straps, insert, and base plate together and place a bolt with lock
washer through each hole (see part list drawing). Screw the bolts into the appropriate
isolators until finger tight. Repeat this procedure for the second mount.
