1.Use a separate power supply for the outdoor unit and indoor unit.
2.Bear in mind ambient conditions (ambient temperature, direct sunlight, rain water, etc.) when proceeding with the wiring and connections.
3.The wire size is the minimum value for metal conduit wiring. The power cord size should be 1 rank thicker consideration of voltage drops. Make sure the
4.Specific wiring requirements should adhere to the wiring regulations of the region.
5.Power supply cords of parts of appliances for outdoor use shall not be lighter than polychloroprene sheathed flexible cord (design 245 IEC57). For example, use wiring such as YZW.
6.A switch with at least 3 mm [1/8in] contact separation in each pole shall be provided by the Air conditioner installation.
Warning:
•Be sure to use specified wires to connect so that no external force is imparted to terminal connections. If connections are not fixed firmly, it may cause heating or fire.
•Be sure to use the appropriate type of overcurrent protection switch. Note that generated overcurrent may include some amount of direct current.
Caution:
•A breaker for current leakage must be attached to the power supply. If no earth leakage breaker is installed, it may cause an electric shock.
•Do not use anything other than breaker and fuse with correct capacity. Using fuse and wire or copper wire with too large capacity may cause a malfunction of unit or fire.
