2-6. CONNECTING WIRES FOR INDOOR UNIT
You can connect indoor/outdoor lead wire without removing the front
grille.
1) Open the front grille.
2) Remove panel.
3) Remove electrical cover.
4) Remove cord clamp.
5) Pass indoor/outdoor unit connecting wire (A) from the back of the
indoor unit and process the end of the wire.
6) 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.
7) Firmly tighten the terminal screws to prevent them from loosening.
After tightening, pull the wires lightly to confirm that they do not
move.
8) Secure indoor/outdoor unit connecting wire (A) and the earth wire
with the cord clamp. Never fail to hook the left claw of the cord
clamp. Attach the cord clamp securely.
2-7. 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 and place them near the rear of
the indoor unit so that they do not contact the front panel.
• Be careful not to crush the connecting pipes when bending them.
FOR LEFT OR LEFT-REAR PIPING
Bundle the connecting pipes and drain hose together, and then wrap
them in felt tape (11).
Cut and use the lower side panels on the left and right sides of the in-
door unit as shown below.
Smooth the cut edges of the side panels so that they will not damage
the insulation coating.
• For left or right piping
• Installing flush against a wall with molding
Wrap the felt tape (11) tightly around the pipes and hose starting near where
the pipes and hose are routed from the indoor unit. (The overlap width of the
felt tape (11) should not be more than 1/2 of the tape width.)
