6) Once the wires are attached to the AIR 403, gently pull the wires down through the
tower sliding the yaw shaft over the 1 1/2“, Schedule 40 steel pipe (Actual OD 1.875
inches, 48mm). Do not use plastic pipe.
7) Slide the yaw shaft all the way down over the end of pole being careful not to pinch the
yaw wires. Be sure to leave enough slack in the wires so that if necessary, the turbine can
be removed.
8) After the yaw is all the way onto the pole, move it back up 1/8th inch (2 mm) to prevent
the bottom of the yaw from contacting the top of the pole. The only contact between the
tower and yaw is through the rubber pad which will reduce the transmission of noise down
the tower.
9) Once the yaw shaft is on the tower, firmly tighten the yaw clamp screws with the 5/32 hex
key. The AIR 403 should yaw freely without restrictions.
10) Check your AIR 403 to be sure that it is securely attached to the mounts. Remember
that this attachment will have to hold in high winds.
11) Attach the assembled hub and blades to the rotor shaft.
12) Run all wires from the turbine to the battery (do not connect wires to the battery). Be
sure to crimp and solder the connections using the appropriate sized connectors. If you plan
to connect an amp meter into your system, see Figure 4, on page 14.
13) Attach your positive (RED) wire to a fuse. Refer to Section 3.1.4 for fusing information.
14) Make sure that your system is properly grounded before proceeding. Refer to the
Grounding Section 3.1.3 on page 11.
IMPORTANT: SEVERE UNIT DAMAGE WILL RESULT FROM IMPROPER GROUNDING.
FAILURE TO PROPERLY GROUND THE TURBINE WILL VOID YOUR WARRANTY.
15) Before attaching the wiring to the battery, make sure that:
- All circuit breakers are in the off position
- The stop switch is in the “stop” or shorted position (if installed)
16) Attach wires to the battery. Red wire to positive, Black wire to Negative.
17) Turn on the circuit breakers and or stop switch.
18) When the blades are rotating very quickly in the wind, you should see the red LED
illuminate.
19) You have now completed the installation process.
