2-2. CONNECTING WIRES FOR OUTDOOR UNIT
1) Remove the service panel and the cable cover.
2) Pass the indoor/outdoor unit connecting wire (B) and power supply cord
(A) through the grommet. 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. Route the cables or wires so as not to deform the
service panel. Otherwise, rainwater may enter the outdoor unit.
7) Close the service panel and the cable cover securely. Make sure that
3-2. PIPE CONNECTION is completed.
