• To avoid electric shock or fire make sure these operations
are carried out by qualified personnel only.
• Ensure that national safety code requirements have been
followed for the main supply circuit.
• Follow all current national safety code requirements.
• Ensure that a properly sized and connected ground wire is
in place.
• Check that voltage and frequency of the mains power
supply are those required; the available power must
be adequate to operate any other possible appliances
connected to the same line.
• Check that the impedance of the mains power supply is in
conformance with the unit power input indicated in the
rating plate of the unit (EN 61000-3-12).
• Make sure that properly sized disconnecting and safety
switches are installed closed to the unit.

• Protected from opposing winds.
• That allows for the clearances required.
• Which will not obstruct passageways or doors.
• With floor structure adequately strong to support unit
weight and minimize vibration transmission.
Fix the unit with locally purchased bolts buried in the

If the unit is installed in areas where heavy snowfalls
may occur, it is necessary to raise its level at least 200
mm above the usual snow level or alternatively to use
the outdoor unit bracket kit.

the cable must only be replaced by the technical support
in order to prevent any risk.
• Use the specified cables for wiring and connect them
firmly to the terminals.

• Be sure to provide grounding; inappropriate grounding
may cause electric shock.
• Do not connect ground wires to gas pipes, water pipes,
lightning rods or ground wires for telephone cables.
DANGER:

guards or by by-passing any of the safety interlock switches.
Contact the qualified service if one of the following
events takes place:
• hot or damaged power supply cable;
• unusual noise during operation;
• frequent operation of the protection devices;
