No.	Part name		Procedure		Remarks

10	Fan motor	1)	Carry out works of 1 and work of 2 .
		2)	Remove the flange nut fixing the fan motor and the	Propeller fan	Loosened by
			propeller fan.		turning clockwise

∗The flange nut is loosened by turning it clockwise.

(When tightening it, turn it counterclockwise.) 3) Remove the propeller fan.

4) Remove the connector for the fan motor from CDB.

5)Remove fan motor lead wires at lower side from the fan motor lead fixing rubber of the penetrated part of the partition plate.

6) Remove sealing material from the fan motor lead wires at	Flange nut
upper side of the upper penetrated part of the partition
plate.
Remove the sealing material carefully because it is	Propeller fan
reused for the fan motor to be replaced.

7)Remove fixing screws (4 pieces each) while support the fan motor with hands so that it does not fall.

∗Cautions at assembling of fan motor

•Tighten the flange nut with 4.95N•m (50kgf•cm).

•Adjust length of the fan motor lead wire at the fan motor lead fixing rubber so that the fan motor lead is not slackened; otherwise the fan motor lead may

	come to contact with the propeller fan.	Fan motor
	Attach the fan motor lead fixing rubber to the partition
	plate so that the projection is set at the refrigerating	Upper fan motor
	cycle side.	Upper fan motor
	cycle side.
•	Stick the sealing material, which is wound around the
	upper fan motor lead wires, at the position 550mm
	from the connector part.
	(After replacement of the fan motor and after piping
	work, confirm that the fan motor lead wires do not
	come to contact with the propeller fan.)
•	Be sure to bind the removed bundling band with the
	bundling band (procured locally).

XREQUIREMENTX

Be sure to fix the fan motor lead wires to the motor base with metal band of the motor base so that they do not come to contact with the propeller fan.
