Work procedure

Explanatory drawing

1As same as the work procedure of the fan motor

replacing, remove the right side plates (1) and (2).

Right side plate (2)

Right side plate

(1)

2Remove the shielding plate.

As the shielding plate is assembled with screws, take the fixing screws off to divide the plate.

Shielding plate

Shielding plate

3Cut the bunding band which ties 3 sensors together and then remove each sensor to replace them.

1)TC sensor

TC sensor can be mounted and fixed also by removing the sensor holder and inserting the sensor from the backward direction.

	2)	TCJ sensor	TA sensor
		TCJ sensor can be mounted and fixed by	TA sensor
		TCJ sensor can be mounted and fixed by	(Suctioning surface)
		entering the sensor into the sensor holder and
		then push the holder including the sensor on
		the pipes.
	3)	TA sensor	TCJ sensor
	3)	TA sensor	(Red)
		Remove TA sensor together with the holder	(Red)
		Remove TA sensor together with the holder
		because the work space is narrow.
		If remounting of the holder is difficult, direct the
		sensor receiving part to the suction port and	TC sensor
		then mount and fix the sensor to the pipes	TC sensor
		using bunding band, etc.	(Black)
		using bunding band, etc.
