General information

Unit installation
Read this instruction manual thoroughly before starting the
installation.
• This equipment contains R-410A refrigerant, a substance
that is not depleting the ozone layer but must be disposed
of in a proper manner.
When disposing of the unit after its
operational life, remove it carefully.
The unit must be delivered to an appropriate disposal center
or to the original equipment dealer.
• Carefully recover refrigerant within this unit before final
disposal or When servicing.
Never vent refrigerant to atmosphere.
• R410A systems operate at higher pressures than standard
R22 systems.
Do not use R-22 service equipment or Components on
R410A epuipment.
• This unit complies with low-voltage (EEC/72/23) and
electro-magnetic compatibility (EEC/89/336) directives.
• Check that the impedance of the mains power supply is in
conformance with the unit power input indicated in the
electric data table IV, on page 17 (EN 61000-3-11).
• The installation must be carried out by a qualified installer.
• Follow all current national safety code requirements.
In particular 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 for the unit to be installed; the available
power must be adequate to operate any other possible
appliances connected to the same line.
Also ensure that national safety code requirements have been
followed for the mains supply circuit.
• The mains supply must be connected to the indoor unit.
• Connect indoor and outdoor units with field-supplied copper
pipes by means of flare connections.
Use insulated seamless refrigeration grade pipe only, (Cu DHP
type according to ISO1337), degreased and deoxidized,
suitable for operating pressures of at least 4200kPa and for
burst pressure of at least 20700kPa.
Under no circumstances must sanitary type copper pipe be
used.
• Where necessary, used field-supplied 16-17mm I.D. PVC pipe
of appropriate length and with the correct thermal insulation for
the condensate drain extension.
• After the installation thoroughly test system operation and
explain all system functions to the owner.
• Leave this manual with the owner for consultation during future
periodic maintenance.
• Use this unit only for factory approved applications: the unit
cannot be used in laundry or steam pressing premises.
Outdoor unit is suitable for outdoor installation.
• Coupling units which have different control systems, may
cause irreversible damage and void the warranty protection.
The manufacturer declines any liability for system malfunction
resulting from unapproved coupling.

IMPORTANT:
During the unit installation make first refrigerant
connections and then electrical connections. If unit is
uninstalled first disconnect electrical cables, then
refrigerant connections.
WARNING:
Disconnect the mains power supply switch and wait over
2 minutes without touching any internal parts of the unit
before servicing the system or handing any internal parts
of the unit.
• The manufacturer declines any liability for damage resulting
from modifications or errors in the electrical or refrigerant
connections.
• Failure to observe the installation instructions or use of the
unit under conditions other than those indicated in Table III
"Operating limits", will immediately void the unit warranty.
• Failure to observe electric safety codes may cause a fire
hazard in case of short circuits.
• Inspect equipment for damage due to improper transportation
or handling: file an immediate claim with the shipping company.
Do not install or use damaged units.
• In case of any malfunctioning turn the unit off, disconnect the
mains power supply and contact a qualified service engineer.
• Maintenance of the refrigerant circuit must only be carried out
by qualified personnel.
• Do not open the remote control to avoid possible damage.
In case of malfunctioning contact a qualified service engineer.
• Control batteries contain polluting elements.
When exhausted they must be disposed of according to local
requirements.
• All of the manufacturing and packaging materials used for
your new appliance are compatible with the environment
and can be recycled.
• Dispose of the packaging material in accordance with local
requirements.
