NOTE:
1. Please remember the surroundings (environmental temperature, direct sunlight, rain etc.)
2. We consider the minimal size of the metal core as the wire size. So it is recommended you adopt a thicker one as the
power conducting wire so as to avoid power decrease;
3. Connect the grounded wire to both indoor and outdoor units;
4. This chart is just an on-site wire-connecting example. For details, please refer to relative National criteria.
Please refer to the indoor unit wiring diagram for the wiring.
Note: The air-conditioners can connect with Central Control Monitor (CCM). Before operation, please wiring correctly and
