(see section 5.1)
.
2. Install the belt tensioner in the hole to the left of the motor base (as seen from the air intake side) and tighten
the bolt by hand.
3. Install the new V-belt onto the pulleys. Start by placing the belt onto the motor pulley, then over the idler
pulley and then onto the central pulley. Once the V-belt is partially over the pulley, it might be necessary to
start rotate the propeller by hand to help pull the V-belt completely onto the pulley.

4. To torque the belt tensioner to the proper setting place a 24mm wrench onto the 24mm hex on the tensioner.
Turn wrench counterclockwise or clockwise (depend on the fan model) until the single mark on one half of
the belt tensioner is aligned half way between marks 2 and 3 on the opposite half of the tensioner. Hold
tensioner at this setting and tighten the bolt fastening the tensioner to the motor base.
