Propeller fan
Fan motor
(continued)
2. CAUTION for replacement or attachment
1)Insert the propeller fan while aligning the D-cut
surface of the fan motor shaft with the arrow mark
(
) on the fan.
(If the propeller fan is tightly mounted on the shaft
without securing alignment between the D-cut
surface and the arrow mark (
), it may cause the
fan to melt and fall off due to friction heat.)
2)Be sure to put the square washer in place.
(Otherwise, unusual noises and vibrations may
result.)
3)Tighten the flange nut at a torque of 15N•m
(153kgf•cm).
(To tighten the flange nut, turn it
counterclockwise.)
4)Remove the clamp filter from the fan motor with
trouble, then attach the clamp filter to the
substitution in the same way as before
replacement. (
Turn through
the fan motor lead
once
around the clamp filter.)
