5-5. Wiring Instructions for the Outdoor Unit
G
Be sure to correctly align inter-unit cables A, B, C and D.
G
Use a dedicated A/C circuit for power.
G
To make connections to the outdoor unit, remove the
inspection panel and tubing panel.
G
Do not bring the inter-unit cables or power cable into
contact with tubing or service valves.
G
Use outdoor unit cable fasteners and fasten the inter-
unit cables at the location where the cables are double-
sheathed.
G
Arrange the wiring so that the inter-unit cables are con-
tained in the inspection panel and tubing panel, as
shown in Fig. 31.
