Air Breeze
Owner’s Manual
Your Air Breeze is delivered partially assembled. Assembly requires mount-
ing 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 Breeze.
Torque Specifications:
Blade to hub screw, 1/4 - 20 x 1.25, socket head screw 10 ft-lbs (13.6 Nm)
Hub to rotor nut, 5/8-18, 50 ft-lbs (68 Nm)
Yaw clamp bolts, M5-0.8 x 35 mm 6 ft-lbs (8 Nm)
Start the assembly by mounting the blades (Item1) to the blade hub as
shown in
Fig. 1
. Place a nylock nut (Item 4) in the hexagonal detent on the
back of the blade hub while positioning the blade on the hub.
The blades must be “tilted” into position on the hub and can only be
installed in one orientation.
Place a washer (Item 2) on a 1/4 - 20 socket head screw (Item 3) and
coat the screw threads with Tef-Gel. Pass the screw through the base of
the blade and screw it into the nylock nut. Tighten the screw to 10 ft-lbs
(13.6 Nm). Repeat for the remaining two blades. Nylock nuts may only be
used one time; replace after each use.
If Air Breeze is to be installed on a “tilt-up” tower, mount the blade/hub
assembly to the turbine now. Coat the alternator rotor shaft threads and
blade hub bore with Tef-Gel and slide the hub onto the shaft. 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.
If Air Breeze 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.
