Indoor Wiring
1. Wiring must conform to local and national electric
codes
2. Lift the indoor unit’s panel up, remove the
electrical box cover by loosening the screw as
shown in (Fig.22).
3. Connect each conductor to the terminal of the
indoor unit (L1, L2, S and Ground) based on the
labels of each terminal (Fig. 23).
4. Use strain relief to secure the cable (Fig. 23).
5. Ensure the wire color and location to and from
each terminal are identical between the indoor
and outdoor terminal strips.
6. Wrap any loose cables not connected with
terminals with electrical tape, so that they will not
touch any electrical components.
7. Refer to the wiring diagram located on the
outdoor unit and/or under the front panel of the
indoor unit for proper wiring
8. Heat Controller recommends using 600V THHN
14AWG/4 conductor unshielded stranded copper
cable, however local and national codes for wire
should always be followed based on your specific
application.
