Security precautions
1. You must follow the electric safety regulations when installing the unit.
2. According to the local safety regulations, use a qualified power supply circuit and air switch
(thermal-magnetic breaker).
3. Make sure the power supply matches with the requirement of air conditioner. Unstable power
supply or incorrect wiring may result in electric shock, fire hazard or malfunction.
4. Properly connect the live wire, neutral wire and grounding wire of power socket.
5. Be sure to cut off the power supply before proceeding any work related to electricity and
safety.
6. Do not put the power on before finishing installation.
7. The air conditioner is a first-class electric appliance. It must be properly grounded. Please
make sure it is always grounded effectively, otherwise it may cause electric shock.
8. Do not use for other purposes the yellow-green wire or green wire in air conditioner other
than for grounding.
9. The grounding resistance should comply with national electric safety regulations.
10. Make sure the power supply complies with the requirement of air conditioner. Unstable power
supply or wrong wiring may lead to electric shock.
Electric wiring
• Must connect with ground reliably.
• The exclusive circuit must be used. But removable socket can’t be used because poor contact
of it can cause overheat or cause fire.
• Don’t pull the power cord strongly.
• Connecting method between air conditioners and power cord and interconnecting method of
each individual element with one another should be done according to the wiring diagram on
the unit.
• The air conditioner should be installed in accordance with national wiring regulation.
• An all-pole disconnection switch having a contact separation of at least 3 mm (1/8'') in all poles
should relate to fixed wiring.
• Air switch (thermal-magnetic breaker) should be installed in the circuit.
