5-6. Wiring Instructions for the Outdoor Unit
● Be sure to correctly align inter-unit cables A, B, C and D.
Be sure to perform grounding.
● Attach a ground wire to either the
outdoor unit or indoor unit.
● If there is a grounding terminal
inside the room, use the grounding
screw inside the indoor unit.
● Be sure to apply the provided labels to both
ends of the inter-unit cables to prevent mis-
wiring. The units will not function if the wiring
connections are incorrect.
● Use a dedicated A/C circuit for power.
● To make connections to the outdoor unit, remove the
inspection panel and tubing panel.
● Do not bring the inter-unit cables or power cable into
contact with tubing or service valves.
● Use outdoor unit cable fasteners and fasten the inter-
unit cables at the location where the cables are double-
sheathed.
● Arrange the wiring so that the inter-unit cables are con-
tained in the inspection panel and tubing panel, as
shown in Fig. 32.
