When wiring
ELECTRICAL SHOCK CAN CAUSE SEVERE PERSONAL INJURY OR DEATH. ONLY A QUALIFIED, EXPERIENCED
ELECTRICIANS SHOULD ATTEMPT TO WIRE THIS SYSTEM.
• Do not supply power to the unit until all wiring and tubing are completed or reconnected and checked, to ensure the
grounding.
• Highly dangerous electrical voltages are used in this system. Carefully refer to the wiring diagram and these instructions
when wiring.
Improper connections and inadequate grounding can cause accidental injury and death.
• Ground the unit following local electrical codes.
• The Yellow/Green wire cannot be used for any connection different from the ground connection.
• Connect all wiring tightly. Loose wiring may cause overheating at connection points and a possible fire hazard.
• Do not allow wiring to touch the refrigerant tubing or any moving parts of the fan
• Do not use multi-core cable when wiring the power supply and control lines. Use separate cables for each type of line.
When transporting
Be careful when picking up and moving the indoor and outdoor units. Get a partner to help, and bend your knees when
lifting to reduce strain on your back. Sharp edges or thin aluminium fins on the air conditioner can cut your fingers.
When installing...
... on the floor, at the wall, under the ceiling
Make sure they are strong enough to hold the unit-weight. It may be necessary to build a strong wooden or metal frame
to provide added support.
... In a room
Properly insulate any tubing run inside a room to prevent “sweating”, which can cause dripping and water damage to
walls and floors.
When connecting refrigerant tubing
• Keep all tubing runs as short as possible.
• Use the flare method for connecting tubing.
• Apply refrigerant lubricant to the matching surfaces of the flare and union tubes before connecting them; screw by
hand and then tighten the nut with a torque wrench for a leak-free connection.
• Check carefully for leaks before starting the test run.
NOTE:
Depending on the system type, liquid and gas lines may be either narrow or wide. Therefore, to avoid confusion, the
refrigerant tubing for your particular model is specified as narrow tube for liquid, wide tube for gas.
When servicing
• Turn the power OFF at the main power board before opening the unit to check or repair electrical parts and wiring.
• Keep your fingers and clothing away from any moving parts.
• Clean up the site after the work, remembering to check that no metal scraps or bits of wiring have been left inside the
unit being serviced.
• Ventilate the room during the installation or testing the refrigeration system; make sure that, after the installation, no
gas leaks are present, because this could produce toxic gas and dangerous if in contact with flames or heat-sources.
WARNING

EN 1 - INSTALLATION SITE SELECTION
DO
• Select an appropriate position from which every corner
of the room can be uniformily cooled.
• Select a sufficiently strong location to support the weight
of the unit.
• Select a location where tubing and drain hose have the
shortest run to the outside.
• Allow access for operation and maintenance as well as
unrestricted air flow around the unit.
AVOID
• Direct sunlight.
• Nearby heat sources that may affect unit performance.
• Areas where leakage of flammable gas may be expected.
• Locations where large amounts of oil mist may occur
(such as in kitchen or near factory equipment) because
oil contamination can cause operation problems and may
deform plastic surfaces and parts of the unit.
• Unsteady locations that will cause noise or possible
water leakage.
• Locations where the indoor unit and the remote control
unit will be splashed with water or affected by dampness
or humidity.
• To make holes in areas where electrical wiring or conduits
are located

EN 15 - OUTDOOR/INDOOR UNIT REFRIGERANT CIRCUIT ADDRESS
Indoor units that are part of a multisplit system must be properly configured to be able to communicate with the
outdoor unit over different channels (Indoor A, Indoor B, etc...) of the communication bus.
Each indoor unit address must correspond to the physical connection of the indoor unit to the outdoor unit refrigerant
circuit, i.e.:
Refrigerant Circuit A <--> Indoor Unit Address A
Refrigerant Circuit B <--> Indoor Unit Address B
...
There are three methods to set the address of an indoor unit:
(1) Dip-switch setting: the address is set by mean of a dip-switch located on the indoor unit pcb.
(2) Remote controller procedure: the address is set with the remote control via parameter P08.
(3) Automatic addressing procedure: the address is automatically set on every indoor unit of the system starting the
automatic addressing procedure via parameter P30.
Check that the setting of switch SW2 (PCB) corresponds to the figure:

(3) AUTOMATIC ADDRESSING PROCEDURE
System requirements:
Outdoor unit must have a recent firmware version that supports the automatic addressing procedure.
Indoor units must have a recent firmware version that supports the automatic addressing procedure
Dip-switch for communication address setting on the indoor unit (SW2) must be left to the factory default state, i.e. to
the OFF position.
Activation of automatic addressing procedure with the parameter P30=1
Power on the whole system.
Verify that there is no error on the indoor units, but the “E0” error (address not set - see Auto-diagnosis table).
Switch on the remote controller of any of the indoor units of the system and set the parameter P30=1
•Press the button for a few seconds.
•Press the arrow until you visualize 30.
•Press the button again for a few seconds: the number 0 (factory setting) at the bottom starts flashing.
•Press the arrow to set the number 1.
•Confirm with the button .
• Press to exit the menu.
If the signal is received, the indoor unit will emit 5 consecutive beeps.
After some seconds, every indoor unit will show the following LED combination to confirm that the automatic addressing
procedure has been activated. OPERATION
GREEN
TIMER
BLUE
STANDBY
RED
From this moment until the end of the procedure the indoor units will not receive
anymore the signals from the remote controllers (infrared receiver is disabled).
Execution of automatic addressing procedure
Once the procedure has been activated, the system will run automatically to set
the address of every indoor unit. In this period, compressor and fan motor will be
activated.
Once activated, the procedure takes about 4-5 minutes per outdoor unit circuit to
be completed. This time doesn’t depend on the number of indoor units actually
connected to the outdoor unit, but on the number of refrigerant circuits of the outdoor
unit.
End of automatic addressing procedure
When all the circuits have been tested and the address of every indoor unit has been set, the outdoor unit will stop and
every indoor unit will switch off (standby mode).
In any case (procedure successful or failed) the infrared receiver of every indoor unit will be re-activated.
If there is no error on the indoor units, the system is ready to be used.
If there is the error “E0” (Address not set - see Auto-diagnosis table) on any indoor unit, re-run the automatic addressing
procedure or manually set the address on that indoor unit with the dip-switch or with the remote controller.
(2) ADDRESS SETTING THROUGH REMOTE CONTROLLER WITH PARAMETER P08 (UP TO 8 INDOOR UNITS)
•Press the button for a few seconds.
•Press the arrow until you visualize 08.
•Press the button again for a few seconds: the number
0 (factory setting) at the bottom starts flashing.
•Press the arrow to set the unit’s number.
•Confirm with the button .
• Press to exit the menu.
1 UNIT A 5 UNIT E
2 UNIT B 6 UNIT F
3 UNIT C 7 UNIT G
4 UNIT D 8 UNIT H
If the signal is received, the indoor unit will emit 5 consecutive beeps. Make sure that the signal is received only by the
indoor unit you want to set
• Address setting via remote control cancels and replaces any addresses set with the indoor unit microswitches.
• If you set P08=0, the addresses set with the microswitches of the indoor unit are valid again.
• For electrical connections, refrigerant circuit connection and check, consult the Installation Instruction of outdoor unit.
