•	Do not install the remote controller near the freezing
	box or refrigerator because water proof or drop-proof is
	not applied to this remote controller.
•	Be sure to set the remote sensor vertically on the wall
	surface, etc.

How to install the remote sensor

NOTE 1 : Avoid to twist the remote sensor cable with the power supply cable, etc. or to store them in the same metal pipe, otherwise it causes a malfunction.

1)Peel the sheath of the cable to be connected by approx. 14mm.

2)Twist two cables and pressure-connect them using a wire joint.

3)When an exclusive pressure-connecting tool is not used or soldering connection is used, apply insulation process with an insulation tape.

NOTE 2 : Install the remote sensor apart from the generation source of noise.

NOTE 3 : When noise is induced to the power source of the indoor unit, some measures such as mounting the noise filter is necessary.
