Your Air X is delivered partially assembled. Assembly requires mounting
the blades on the blade hub, securing the hub to the turbine body and
installing the nosecone on the blade hub. The necessary hex key (Allen)
wrenches are furnished with Air X.
Torque Specifications:
Blade to hub bolts, 1/4-20 x 1.25 inch, Socket Head Bolt, 7.0 lb-ft (9.4 N·m)
Hub to rotor nut, 5/8 -18 inch, Jam nut, 50 lb-ft (68 N·m)
Yaw Clamp Bolts, M5 x 35 mm, Socket Head Bolt, 4.0 lb-ft (5.4 N·m)
Start the assembly by examining how the blades mount to the hub, refer to
Fig 1
. Using the Tef-Gel supplied with the Air X, apply a coat of Tef-Gel to
the blade root and hub. The use of Tef-Gel is recommended for all installa-
tions but is mandatory in marine environments.
The goal is to provide a coating of Tef-Gel between the blade root and
blade hub so that the blade material does not directly contact the alumi-
num hub. This is particularly important for marine installations since the
blades and hub may severely deteriorate in high moisture (particularly
marine) environments.
After coating the hub and blades with Tef-Gel place a nylock nut (Item 4)
in the detent on the back of the blade hub while positioning a blade on
the hub. Pass a bolt through the blade and screw it into the nylock nut –
do not fully tighten the bolt yet. Install the second bolt and nylock nut and
torque both bolts to
If Air X is to be installed on a “tilt-up” tower, mount the blade/hub assem-
bly to the turbine now. Start the 5/8-18 hub nut on shaft threads and
“spin” the hub completely onto the turbine
alternator shaft. Fully tighten the hub to
50 ft-lbs (68 Nm) by inserting a 5/16 inch
hex key wrench in the turbine alternator
shaft and turning the shaft while turning
the blades.
Caution
- blades are sharp!
If Air X is to be installed after the tower is erected, it will be safer and
easier to first install the turbine body on the tower and then install the
hub/blade assembly. This will avoid attempting to mount the turbine while
the blades are spinning – a dangerous condition.
Snap the nosecone into position over the outside edges of the blade hub.
Make sure all three edges of the nosecone snap over the edge of the
blade hub. After installation tug on the nosecone to make sure it is secure-
ly attached.

IMPORTANT:
Tef-Gel is a corrosion inhibitor and
is especially important in marine applications.
WARNING:
Don’t
attempt to mount the
turbine while blades
are spinning.
