Considering piping and wire connecting works in the
ceiling after hanging down the indoor unit, select an
installation place and then determine the drawing-out
direction of the pipes.
• If the ceiling has been already set, draw the
refrigerant pipe, drain pipe, inter-unit wire between
indoor and outdoor units, central control system
wire and remote controller cord up to the positions
where pipes and wires are connected before
hanging down the indoor unit.
• Install the indoor unit/outdoor unit and also arrange
the power supply wiring, connecting wiring and
remote controller wiring 1m apart from the television
and the radio in order to avoid image turbulence
and noise.
