◆Electric Wiring
1. All the electric work must be done according to the wiring diagram.
2. Check for the correct voltage of the unit.
3. Don’t pull the power cord strongly.
4. The air conditioner must be safely grounded! Grounding wire must be connected to the building and
done by the qualified personnel. In fixed circuit, there must be electricity leakage protection switch of
enough power capacity and air switch with enough space. Air switch (thermal-magnetic breaker) can
protect the short circuit and over load.
◆Grounding Requirement
1. The air conditioner is class 1 appliance, so it must connect with ground reliably.
2. The yellow-green wires in the air conditioner are grounding wires and can’t be used for other purposes.
3. The grounding-resistance should conform to the requirement of IEC Standard.
