Connection can be made without removing the front panel.
1. Open the front grille, remove the screw (2 pieces), and remove the electrical box
cover.
* Electrical work can be conducted more effectively with the panel removed.
When attaching the panel, check that the hooks K at three locations on the air
outlet side are connected securely.
2. Securely connect each wire to the terminal block.
* In consideration of servicing, provide extra length for each of the wires.
* Take care when using strand wires, because beards may cause the wiring to
short out.
3. Install the parts that were removed back to their original condition.
4. When going through the right side of the indoor unit, cut out the removable
section of the Corner box E.
