Part 6 Service Diagnosis
2. Procedure for checking indoor-outdoor unit transmission wiring for broken wires (for
checking the indoor-outdoor unit transmission wiring of the "Outdoor Unit C" for broken
wires)
Turn OFF the power supply to all equipment, short circuit between the indoor-outdoor unit
terminal F1 and F2 in the "Outdoor Unit C", and then conduct continuity checks between the
transmission wirings F1 and F2 of the "Indoor Unit a" that is farthest from the "Outdoor Unit
C" using a multimeter. If there is continuity between the said transmission wirings, the
indoor-outdoor unit transmission wiring has no broken wires in it.
If there is no continuity, the transmission wiring may have broken wires. With the
indoor-outdoor unit terminal of the "Outdoor Unit C" short circuited, identify the place with
continuity in the transmission wiring of the "Indoor Unit b", transmission wiring of the "Indoor
Unit c", and transmission wiring of the "Indoor Unit d" in the order described.
If the place with continuity can be identified, there may be broken wires in places before the
said place with continuity.
