Indoor Unit Installation Instructions
Connecting the Signal Cable
Color selection does not matter as much as matching number to number does. Consult the
diagram affixed to the indoor and outdoor unit respectively for specific wiring instructions.
There are 3 terminals (1, 2 , 3) and ground (G). Do not mix up the wires between each ends.
It is vital that the colors between the indoor and outdoor unit match for each terminal.
A simplified wiring diagram is included in the Appendix section of this manual on Page 44.
On the indoor unit, the wiring diagram is located underneath the front panel as shown below:
