The method of using circular terminal is shown in the figure. Take off the screw, connect it to the terminal after placing
it through the ring at the end of the lead and tighten it down.
2. Connect using straight terminals:
The method of using straight terminals is shown as follows: loosen the screw before putting the wire into the terminal
block, tighten the screw and confirm it has been tightened by pulling the line gently.
3. Clamp the wires:
Secure the wires with clips which should press on the insulation of the wires.

• Follow local codes when selecting wire gauge and connecting to house power.
• Use the cable strain relief clips and locking conduit clamps to prevent wires from being pulled off terminal posts.
• Unit must be properly grounded. Do not use water or gas piping, phone ground or lightning rod.
CAUTION
• Only copper wire can be used. A properly sized breaker should be provided, or electric shock may occur.
• Unit requires 208/230VAC – L1, L2 wire and a ground. No neutral is required.
• All indoor units should be wired to the same breaker to prevent some of the units from being powered off while
others are energized.
• Controller wiring and refrigerant tubing can be arranged and ran together.
• Disconnect power from both outdoor and indoor units prior to servicing any component in the system.
