ELECTRIC WORK
Wire connection
• Prior to connection of the wire between indoor and outdoor units, be sure to adjust wire numbers. Incorrect
connection causes a trouble.
• As the remote controller wire has no polarity, there is no problem if connections to indoor unit terminal blocks
A and B are reversed.
• Be sure to pass the wire through the bushing at wire connecting port of the indoor unit.
• The low-voltage circuit is provided for the remote controller.
• After connecting the wire to the terminal block, make a trap on the wire and then fix the wire with a wire clamp.
