4. How to Install the Outdoor Unit
First refer to Section 2. Installation Site Selection.
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 elec-
trical codes. Make sure that the installation fully complies
with all local and national regulations.
(1) Remove the 3 screws from the inspection panel.
(Fig. 46a)
Remove the inspection panel by sliding it downward
and pulling it toward you. (Fig. 46b)
(2) Connect the inter-unit and power supply line accord-
ing to the wiring system diagram on the inspection
panel. (Fig. 46c)
(3) When connections are completed, check that all
connections are correct as shown in the wiring sys-
tem diagram.
(4) Be sure to ground the unit according to your local
codes.
4-2. Routing the Tubing and Wiring
The tubing and wiring can be extended out in 3 direc-
tions: front, rear, and right. Use a nipper or similar
tool to cut out the knockout holes for the inter-unit
control wiring outlet, power wiring outlet, and tubing
outlet from the appropriate covers A and B. (Fig. 46d)
CAUTION
Route the tubing so that it does not contact the
compressor, panel, or other parts inside the unit.
Increased noise will result if the tubing contacts
these parts.
When routing the tubing, use a tube bender to
bend the tubes.
