This equipment must be properly earthed.
Note:
Isolating Devices (Disconnecting means) should have minimum 3.0 mm contact gap.
Ensure the colour of wires of outdoor unit and the terminal Nos. are the same to the indoor’s respectively.
Earth wire shall be Yellow/Green (Y/G) in colour and longer than other AC wires as shown in the figure for the

Since the fl are part comes into contact with the
connections, carefully check the fl are fi nish.
