Note:
All wires between indoor and outdoor units must be
connected by a qualified electric contractor.
• Electric wires must be connected correctly. Improper
connection may cause malfunction.
• Tighten the terminal screws .
• After tightening the screws, pull the wire slightly to
confirm whether it's firm or not.
• Make sure that the electric connections are earthed
properly to prevent electric shock.
• Make sure that all wiring connections are secure and the
cover plates are reinstalled properly. Poor installation
may cause fire or electric shock.
Installation of indoor unit
