    IMPORTANT SAFETy INSTRUCTIONS READ THESE INSTRUCTIONS IN THEIR ENTIRETy bEFORE INSTALLING. SAVE THESE INSTRUCTIONS. This manual contains important instructions for constructing foundations, and raising, lowering and leveling towers that MUST be followed. Read, Understand and Follow all warnings. In this manual Read these instructions in their entirety before starting foundation construction and tower installation.

  • Page 4: Prior To Installation

    PRIOR TO INSTALLATION Introduction This manual provides information for the construction of a foundation suitable for installing Southwest Windpower’s Skystream 3.7 on one of the following Southwest Windpower towers: • 33.5 ft (10.2 m) Monopole Sectional Tower, part number 3-CMBP-3218 •...

  • Page 5: Building Permits & Zoning Requirements

    Installation Personnel Southwest Windpower strongly recommends professional construction of the foundation. Constructing the foundation requires specialized equipment, experience constructing concrete forms and knowledge of local zoning and building codes and inspection requirements.

  • Page 6: Siting - Finding The Best Location For Skystream

    Siting – Finding the best location for Skystream The optimum location to install any wind turbine, including Skystream, is often a compromise. Local building restrictions, the height of surrounding structures, wire length, and available open space may require Skystream be installed in a less than optimum location. At a minimum try to observe the following general rule for siting the turbine.
  • Page 7 When raising the 45 ft (13.7 m) tower using the Gin Pole Kit a minimum of approximately 110 ft (37 m) are required. Slightly over 50 ft (17) are required on one side of the foundation for the tower and Skystream blades. Depending on the length of vehicle used to raise the tower, over 60 ft (20 m) may be required on the other side of the foundation for the vehicle, pulling cable and gin pole.

  • Page 9: Soil Conditions

    Soil Conditions As with the Wind Zones described above the size of a foundation required to support a wind turbine and tower is in part determined by the soil conditions in which the foundation is constructed. Loose sandy soil will require a larger foundation than bedrock. Refer to the following tables to determine your Soil Class and the location of the foundation dimensions for your tower height and foundation type.

  • Page 10: Selecting A Foundation Configuration

    Selecting a Foundation Configuration – Pier, Mat or SMarT The choice of foundation – Pier, Mat or SMarT foundation – will depend on a number of factors including soil conditions, the depth of the local water table, frost line and available excavation equipment. If, for example, a contractor has the correct size auger, installing a Pier foundation may be a more economical choice than a Mat foundation since it may use substantially less concrete.
  • Page 11 Positioning the Foundation bolts (Pier and Mat foundations) Regardless of the foundation – Pier or Mat - it is vital the foundation bolts are correctly positioned in the foundation or it may be extremely difficult if not impossible to mount the tower to the foundation. Using the paper template supplied with the foundation bolt kit as a guide, construct a wooden template to position the foundation “J”...

  • Page 13: Positioning The Foundations Bolts (Smart Foundation)

    Positioning the Foundation bolts (SMarT Foundation) The SMarT Foundation includes a template as part of the foundation kit therefore the construction of a template is not required. Refer to the SMarT Foundation instructions located in Appendix C of this manual. Electrical Conduit Electrical conduit may be cast into the foundation such that the conduit continues below grade to electrical panel.

    To join the tower sections together : • Inspect the mating sections of the tower sections for burrs and roughness and smooth and repair as necessary. • Mark the base section 26 in (66 cm) from the upper end of the section. This mark will be used to determine full insertion of the base section. •...

  • Page 17: Raising The Tower

    Refer to the Skystream Owners Manual for instructions on completing the electrical connections and mounting Skystream on the tower. If you have not raised a tower before Southwest Windpower recommends first raising the tower without the windturbine installed. This provides the opportunity to practice the procedure without risking damage to the windturbine.
  • Page 18 • Install the second U-Bolt clip as near the thimble as possible. As with the previous U-Bolt clip, tighten the nuts evenly, alternating from one nut to the other until reaching 30 lb-ft (41 N-m) of torque. • Install the third U-Bolt clip midway between the other clips and tighten the nuts to 30 lb-ft (41 N-m) of torque. •...

  • Page 19: Lowering The Tower

    Lowering the Tower Lowering the tower is essentially the reverse of raising the tower. Observe the same precautions including not passing under the tower as it is lowered and standing well clear of cables. As with raising the tower, a minimum of three people are recommended. Use extreme caution when lowering the tower.

  • Page 20: Leveling The Tower

    Leveling the Tower Leveling the tower is most easily accomplished using only four of the eight foundation bolts. Once the tower is leveled the remaining bolts can be fully tightened to secure the tower. Be aware that leveling the tower may require some trial and error adjustments – even though the base is level, the upper tower flange may be off level due to manufacturing tolerances.
