Electrical System Installation

Due to our policy of continuous product innovation, some specifications may change without notification.

ELECTRICAL SYSTEM INSTALLATION

Do not install power wiring to the outdoor unit

and the communication / connection (power) cable

to the indoor unit in the same conduit. Use separate

conduits. Communication problems will occur.

Connecting Outdoor Unit Wiring, continued.

6. Using a JIS screwdriver, connect wires as shown at right. See

also indoor unit wiring diagram found on its bottom cover, and

outdoor unit wiring diagram on the inside of its chassis cover.

• Each wire must be individually and securely attached to each

terminal.

Loose, damaged, or cracked wires will cause electric shock, bodily

injury and / or death.

Loose wires can cause the wiring to burn out, damaging the outdoor

unit.

• Secure wiring / cables with cable ties.

• Pay attention to the location / connection of the ground cable.

• Maintain a minimum of 1/4 inches of wire length from terminal block

to cable bundle.

7. When finished, reattach the piping / control box cover or con-

trol box cover (depends on model) to the outdoor unit with the

screws.
