4. How to Install the Outdoor Unit
First refer to Section 2. Installation Site Selection.
The drain hole at the bottom of the outdoor unit was
not plugged at the time of factory shipment. If neces-
sary, plug the drain hole with the accessory drain cap
or mount the accessory drain elbow before installing
the outdoor unit. (Fig. 45a or 45b)
4-1. Wiring Instructions for the Outdoor Unit
Regulations on wire size differ from locality to locality.
For field wiring requirements, please refer to your local
electrical codes. Make sure that the installation fully
complies with all local and national regulations.
(1) Remove access panel “C”. (Fig. 46)
(2) Connect the inter-unit wiring and power line
according to the drawing on the panel side.
(3) Be sure to size each wire allowing approx. 10 cm
longer than the required length for wiring. Store
excess wiring inside the cabinet.
(4) When connections are completed, check that all
connections are correct as shown in the wiring
system diagram on panel side.
(5) Be sure to ground the unit according to your local
codes.
