5 ELECTRIC WIRING WORK
General instructions
All field wiring and components must be installed by a licensed
electrician and must comply with relevant European and national
regulations.
Use copper wire only.
A circuit breaker capable of shutting down power supply to the
entire system must be installed.
Note that the operation will restart automatically if the main
power supply is turned off and then turned back on again.
Be sure to ground the air conditioner.
Do not connect the ground wire to gas pipes, water pipes,
lightning rods, or telephone ground wires.
- Gas pipes: might cause explosions or fire if gas leaks.
- Water pipes: no grounding effect if hard vinyl piping is used.
- Telephone ground wires or lightning rods: might cause
abnormally highelectric potential in the ground during
lightning storms .
Follow the 'Wiring diagram' attached to the unit body to wire the
outdoor unit, indoor units and the remote controller.
