(1) The power supply inlet is located at the lower
area of the refrigerant tubing side.
The electrical component box is located at the
refrigerant tubing side.
(2) Before installing the panel for cassette, be sure
to carry out the wiring connection.
(3) Remove the lid located on the electrical
component box by unscrewing the screws
(M4 × L6) (×4).
(4) Lead the wires from the power supply inlet to
the unit. Be sure to lead the wires through the
