1. Refrigerant piping system, indoor unit-indoor unit connection
signal wires and indoor unit-outdoor unit connection singal wire
are in the same system.
2. When power cord is parallel with signal wire, please put them
into separate wire distribution pipes, and leave a proper distance.
(Reference distance: It is 300mm when current capacity of
power cord is less than 10A, or 500mm when 50A).
Please use shield wire as indoor unit/outdoor unit signal wire.

(Weak electric signal)
Indoor/Outdoor unit signal wire is low voltage circuit. Do not
let it touch the high voltage power wire and put it to gather
with power cord in the same wire distribution pipe.
1. Signal wire is three-core, polarized wire. Use three-core shield
wire to prevent interference. The grounding method now is
grounding the closed end of the shield wire and opening
(insulating) at the end. Shield is to be grounded.
2. The control between outdoor unit and indoor unit is BUS type.
Addresses is set on field during the installation.
