Be sure to ground the air conditioner.

Do not connect the ground wire to gas pipes, plumbing pipes, lightning rods, or telephone ground wires.

Gas pipes: could explode and cause fires if there was a gas leak.

Plumbing pipes: no grounding effect if hard vinyl pipes are used.

Telephone ground wires or lightning rods: the ground potential could rise dangerously high if hit by light-
ning.

• Specifications for field wire

The remote controller cord should be procured locally. Refer to the Table 4 when preparing one.

Method of wiring units and connecting remote controller cords

Wiring the units connections
See “INDOOR UNIT INSTALLATION” and detach the right side panel. Next, remove screw (A) and slide 
front cover to the right (B) and detach.
When detached, you can see the terminal boards. Feed wires through the clamp and connect to the termi-
nal board.

Remote controller cord connections (not necessary for slave unit of simultaneous operation system)
Feed wires through the clamp and connect to the terminal board for transmission wiring. (no polarity)

[ PRECAUTIONS ]

Do not clamp remote controller cords together with wiring the units. Doing so may cause malfunction.

Remote controller cords and wiring the units should be located at least 50 mm from other electric wires. Not
