1 Power transformer (TR1)					..................... Indoor unit	*Measure the coil resistance.
•	Primary	230-208V		; Measure the resistance between No.1 and No.3
				(WHT lead wires) terminals of 3P (WHT) socket connected to
				power transformer.
•	Secondary		14.8V	; Measure the resistance between No.1 and No.2
				(RED lead wires).
			14.8V	; Measure the resistance between No.3 and No.4
				(BRN lead wires).
	Refer to “1-3 Other component specifications”.
2 Power transformer (TR) .................... Outdoor unit						*Measure the coil resistance.
•	Primary	230-208V		; Measure the resistance between No.1 and No.3
					(WHT lead wires) terminals of 3P(WHT) socket jointed to power
					transformer.
•	Secondary		14 V ; Measure the resistance between No.1 and No.2
					(BRN lead wires).
	Refer to “1-3 Other component specifications”.
3 Indoor fan motor (FMI)				.........................	Indoor unit *Measure the coil resistance.

•Measure the resistance between each terminal of 9P (WHT) socket connected to the indoor fan motor.

Refer to “1–2–(A) Major component specifications”.

4 Outdoor fan motor (FMO) .....................Outdoor unit *Measure the coil resistance.

•Measure the resistance in the same manner as explained above 3. Refer to “1–2–(B)Major component specifications”.
