Typical Wiring Diagram
1. Adjust the length of the interconnecting wires so that it can easily reach the Floor Ceiling
electrical control box.
2. Open electrical control box cover and route the interconnecting wires to field wiring terminal block.
NOTE:
The indoor unit is powered from the outdoor unit, depending on local code, a
disconnect switch may need to be installed to a power supply circuit.
3. Secure interconnecting wires to the terminal block
as shown in the connection diagram at right:
NOTE:
Record wire colors and terminal references
for uses with Outdoor Unit wire connections.
4. Secure all wires inside wire clamp/strain relief. Verify wires
are secure, not loose and no external force on wires affects the connections at the terminals.
NOTE:
Crossing interconnecting wires will cause system malfunction and possible damage.
