WARNINGS!
Improper wiring between the indoor and outdoor units can cause serious damage to the system
and risk to personal injury or fire. Use caution when connecting the wiring to ensure that the
wires are connected properly.
DO NOT use thermostat wire to connect indoor and outdoor units. DO NOT cross wires!
If a condensate pump is needed, it must be connected to the supply power at the outdoor unit.
8.6.2 Five Port
Connecting the Cable to the Outdoor Unit
1. Remove screws to take off front side panel.
2. Feed cable wire through knock-out holes on the right side panel. (A water tight cable
strain relief or conduit is recommended here.)
3. Connect the wires to the terminals.
4. Replace front side panel with the screws.
5. Secure wire cables.
Typical Wiring Connections
Note: When connecting lines, connect in the most convenient sequence according to your installation considering line set
sizes. Example: If installation consists of three (3) 9K indoor units it would be easier to use ports C, D, and E, since no
adapter would be required. Another example would be installation of an 18K indoor unit and (2) 9K indoor units. The best
ports to use here would be B, C, D, (or E) again no adapter is required.
