Safety procedures
Units installation
The installation must be carried out by a qualified
installer.
DO NOT INSTALL IN A PLACE...
• Difficult to access for installation and maintenance.
• Too close to heat sources.
• That might increase the vibration of the unit.
• Which cannot bear the weight of the unit.
• Subject to a risk of exposure to a combustible gas.
• Exposed to oils and vapours.
• With particular environmental conditions.

Electrical connections

All field electrical connections are the responsibility of
the installer.
DANGER
Electrical shock can cause severe personal injury
or death. These operations are carried out by
qualified personnel only.
WARNING
• This unit complies with low voltage (2006/95/EC),
electromagnetic compatibility (2004/108/EC) and pressure
equipment (EEC/97/23) Directives.
• 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.
• Make sure that properly sized disconnecting and safety
switches are installed.
• The disconnection devices from the mains supply must
allow full disconnection under the conditions provided for
by overvoltage class III.
CAUTION
• Connect the connecting cable correctly. If the connecting
cable is connected in a wrong way, electric parts may be
damaged.
OUTDOOR UNIT
CHOOSE A PLACE...
• Where noise and discharged air do not disturb neighbors.
• 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
block.
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.
• Connection to the mains supply is of the Y type; therefore,
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.
WARNING
• 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:
Do not modify this unit by removing any of the safety
guards or by by-passing any of the safety interlock switches.
FINAL CHECK
WARNING
• If refrigerant gas leaks out during the installation
work, ventilate the room immediately.
• If refrigerant gas leaks into the room and flows near a
fire source, such as a cooking range, poisonous gas is
generated.
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;
• unusual smell (such as smell of burning).
