Remarks
M Cautions when exchange/reassembling the
fan motor
1) Match the D-cut surface of the motor with the
mark on the fan, insert the propeller fan.
(If tightening the D-cut surface when out of
position, the propeller fan will melt due to
friction heat, which will cause the unit to
malfunction.)
2) Be sure to attach the square washer.
(Failure to do so will result in abnormal sound
and vibration being generated.)
3) Tighten the flange nut with 15N•m
(153kg•cm).
4) Insert the hooking tabs on the discharge
cabinet securely into the tab holes on the
