• Install an all-pole switch with a contact opening width of at least 3 mm on the
installation side.
• Ensure that the mains voltage supply has a residual current circuit breaker.
• Make sure that the grounding cable of the air conditioner is connected to the
vehicle's grounding system.
There are two ways of installing the roof air conditioner:
• Making a new opening (chapter "Making a new opening" on page 15). In this
case the opening must be reinforced by an appropriate frame.
• Using an existing opening in the vehicle such as a roof hatch or replacing an
old air conditioner (chapter "Installing in an existing opening" on page 16).

➤ Carefully cut out the opening on the roof using a keyhole saw or a similar
tool (B).
