2-4. INDOOR UNIT INSTALLATION
2-4-1. INSTALLING THE INDOOR UNIT ON THE FLOOR
1. Place the indoor unit on the flat floor.
2. Fix the indoor unit at 4 points with the included wood screws (9) and
washers (10). Tighten the screws securely.

2. Fix the indoor unit at 4 points with the included wood screws (9) and
washers (10). Tighten the screws securely.
2-4-3. EMBEDDING THE INDOOR UNIT IN A WALL

2-5. CoNNECTING WIRES FoR INDooR uNIT
1) Remove VA clamp.
2) Pass indoor/outdoor unit connecting wire (A) from the back of the indoor unit
and process the end of the wire.
3) Loosen terminal screw, and connect first the earth wire, then indoor/outdoor
unit connecting wire (A) to the terminal block. Be careful not to make mis-
wiring. Fix the wire to the terminal block securely so that no part of its core is
appeared, and no external force is conveyed to the connecting section of the
terminal block.
4) Firmly tighten the terminal screws to prevent them from loosening. After tight-
ening, pull the wires lightly to confirm that they do not move.
5) Secure indoor/outdoor unit connecting wire (A) and the earth wire with the VA
clamp. Never fail to hook the left claw of the VA clamp. Attach the VA clamp
securely.
• Make earth wire a little longer than others. (More than 45 mm)
• For future servicing, give extra length to the connecting wires.
• Do not fold the excess wire, or cram it into small space. Take caution not to
damage the wires.
• Be sure to attach each screw to its correspondent terminal when securing the
cord and/or the wire to the terminal block.
2-6. PIPE FoRMING aND INSTallaTIoN
Pipe Forming
• Route the drain hose diagonally below the connecting pipes.
• Make sure that the drain hose is not routed upward and that there are no
waves in the hose.
• Do not pull the hose when applying the tape.
• Route the piping so that it does not project past the rear of the indoor unit. (Refer
to the figure to the right.)
Connecting Pipe Installation
• Install the connecting pipes so that the piping can move slightly to the front,
back, left, and right.
• Be sure to insulate the connecting pipes so that they do not contact the panel.
• Be careful not to crush the connecting pipes when bending them.
