Twist Pair Cable with Shield Tube:
Use a 0.3 to 0.75mm cable for connecting.The maximum total cable length is up 30m.If the total cable length exceeds 30m, use a twist pair cable
with shield tube(1P-0.75mm or more).In that case,the maximum total cable length is up to 500m.If using in combination with the control timer,the
allowable total cable length is up to 100m.The use of a cable other than that specified above can cause of malfunction due to the effects of noise.

Keep a distance more than 30cm between the transmission line (remote control switch cable and transmission wires) and power source of the indoor
units. If not, the air-conditioner may not operate properly or malfunction may occur due to effect of power source noise.
In case of simultaneously controlling multiple indoor units, set the refrigerant cycle numbers and addresses of the indoor units without overlapping.
No gap shall exist between the remote control switch cable and hole of the remote cotrol switch case. If there is a gap, cover the gap with vinyl tape.
If not, malfunction may occur due to entrance of water droplets or insects.

C.In case that the indicated number is not correct, the auto-address function is not performed corr-
ectly due to incorrect wiring, the electric noise or etc.
Turn OFF the power supply and correct the wiring after checking the following points;
(Do not repeat turning ON and OFF within 10 seconds.)
1. Power Supply for Indoor Unit is Not Turned ON or Incorrect Wiring.
2. Incorrect Connection of Connecting Cable between Indoor Units or
