NOTICE :

1.Separately wire the high and low voltage lines.

2.Use heat resistant electrical wiring capable of withstanding temperatures up to 75°C(167°F).

3.Use outdoor waterproof connection cable rated for at least 300V for the connection between indoor and outdoor unit. (For example, Type SJO-WA)

WARNING:

Be sure to comply with local and national codes while running the wire from the indoor unit to the outdoor unit(size of wire and wiring method, etc).

Every wire must be connected firmly.

No wire should be allowed to touch refrigerant tubing, the compressor or any moving parts.
