1. Using a phillips head screwdriver, remove the conduit panel cover from the outside unit.

2. Before proceeding, inspect all wiring inside the casing to be sure they are secure and have not come loose during transportation and

installation of the outdoor unit.

•Loose wires can cause the wiring to burn out quickly.

•Inspect wires for any damage or cracks (manufacturing defects).

3. Confirm that electrical power supply capacity is sufficient to run the unit. See specifications sheets at the beginning of this installation

manual for details on power.

4. Confirm that you are using the right gauge size for wiring to proceed.

5. Using a screwdriver, connect the wires as shown in Figures 64 and 65.

•Each wire should be securely attached to the terminal block.

•Bundle the cabling by using a cable restrainer.

•Pay attention to the location/connection of the green/yellow grounding cable; as in some models the connection may be located to the side

of the actual terminal block.

•Maintain a minimum of .2” of wire length from terminal block to cable bundle.
