2-1. INSTALLING THE UNIT
• Be sure to fix the unit's legs with bolts when installing it.
• Be sure to install the unit firmly to ensure that it does not fall by an earthquake or a gust.
• Refer to the figure in the right for concrete foundation.
• Do not use the drain socket and the drain caps in the cold region.
Drain may freeze and it makes the fan stop.
• Remove the tape on the panel when opening the package. (DO NOT remove the LABELS on the panel.)

2-2. CONNECTING WIRES FOR OUTDOOR UNIT
1) Remove the service panel.
2) Loosen terminal screw, and connect indoor/outdoor unit connecting wire (B)
from the indoor unit correctly on 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.
3) Firmly tighten the terminal screws to prevent them from loosening. After
tightening, pull the wires lightly to confirm that they do not move.
4) Perform 2) and 3) for each indoor unit.
5) Connect power supply cord (A).
6) Fix indoor/outdoor unit connecting wire (B) and power supply cord (A) with
the cable clamps.
7) Close the service panel securely. Make sure that 3-3. PIPE CONNECTION
is completed.
• After making connections between both power supply cord (A) and indoor/
outdoor unit connecting wire (B), be sure to fix both cable and wire with cable
clamps.
Note:
• Removing the handle increases the effectiveness of the wiring operation.
• Be sure to reinstall the handle.
