SPECIAL PRECAUTIONS
• During installation, connect before the refrigerant system and
then the wiring one; proceed in the reverse orden when removing
the units.
When wiring
ELECTRICAL SHOCK CAN CAUSE SEVERE
PERSONAL INJURY OR DEATH. ONLY 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, compressor,
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...
• 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
CAUTION
WARNING
… In a ceiling
Make sure the ceiling is 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.
... In moist or uneven locations
Use a raised concrete base to provide a solid level foundation
for the outdoor unit. This prevents damage and abnormal
vibrations.
... In area with strong winds
Securely anchor the outdoor unit down with bolts and a metal
frame. Provide a suitable air baffle.
... In a snowy area (for heat pump-type systems)
Install the outdoor unit on a raised platform that is higher then
drifting snow. Provide snow vents.

6. FUNCTIONS
6-1 Cool Mode Operation
In Cooling Mode, the operation of the compressor (CM), Outdoor Fan (FMO) and Indoor Fan (FMI) are
determined by the difference between the room air temperature (RAT) and the set point temperature (SPT)
as shown in the graph.
NOTES
1. In this graph, the FMI is operating with the “Auto Fan Speed” setting. If the user has selected the Low,
Medium or High fan speed, the FMI will run constantly at that speed only.
2. In addition to the temperature difference of above, the operations of the main components (CM, FMO,
FMI) is also controlled by protection delays. That is: - the minimum off time of compressor is 3 minutes. -
- the minimum off time of compressor is 3 minutes. -
- the indoor fan can change speed only after it has operated at the same speed for 30 sec if in AUTO
and 1 sec for the other settings (High, Med, Low).
11

6-2 Dry Mode Operation
Dry operation remove moisture from indoor air running, in cooling mode, at a low level without reducing the
ambient temperature. This is done cycling ON and OFF indoor and outdoor units according to below.
SPT = Set Point Temperature
6-3 Fan Mode Operation
With this mode, the indoor fan is turned ON while CM and FMO stay OFF all the time. The user can select
between 4 speeds: HIGH, MEDIUM and LOW.
6-4 Auto Fan Speed
With this option selected, the indoor fan speed changes automatically according to the difference between
the detected air temperature (RAT sensor) and the set point (SPT):
COOLING MODE
2 ≤(RAT – SPT): HIGH speed
1 ≤(RAT – SPT) <2: MEDIUM speed
(RAT – SPT) <1: LOW speed

6-5 Forced Mode
In this mode the system operates (COOLING or HEATING mode – fixed settings) or is switched off by
means of the MODE button of the indoor unit control board. The operation modes can be selected
pressing the button in a cyclic way (OFF COOL HEAT OFF…). The settings are:
COOLING mode
SET POINT temperature = 25°C
FAN SPEED = HIGH
6-6 Protection Operations in Cool and Dry Mode
Freeze-up
This protection prevents ice formation on the indoor coil heat exchanger.
The protection is activated by the indoor coil temperature (ICT sensor) and only after 6 minutes
of compressor operation.
This protection acts in 2 levels:
LEVEL 1
INDOOR FAN SPEED: ANY (as selected from remote controller)
COMPRESSOR: ON
OUTDOOR FAN: cycling (30 seconds ON B30 seconds OFF).
DRAIN PUMP: operates according to paragraph 9.2
LEVEL 2
INDOOR FAN SPEED: ANY (as selected from remote controller)
COMPRESSOR: OFF for at least 6 minutes and until ICT 8°C
OUTDOOR FAN: OFF for at least 6 minutes and until ICT 8°C
DRAIN PUMP: always ON ( stops when exiting the protection)
The system exit this protection routine when ICT temperature rises above 8°C.
13

6-7 I FEEL Function
As standard configuration the air conditioner operates detecting the room temperature through the sensor
equipped in the wireless remote controller (icon I FEEL shown on the display). This feature provides a
personalised environment since the temperature can be detected where the remote controller is located.
It is possible to de-activate this option pressing the I FEEL button on the remote controller.
In this case the I FEEL icon is no longer displayed and room temperature is detected through the sensor
included in the indoor unit.
6-8 NIGHT Function
When this function is active, room temperature changes automatically to compensate for body temperature
variations while sleeping. After 10 hours of operation system switches automatically to OFF state.
This mode of operation is available both in COOLING and HEATING mode.
When running in this mode indoor fan is automatically switched to LOW speed.
6-9 DRAIN PUMP
Pump operates when the unit is running in COOLING and DRY modes.
The level detection is done through a float switch connected at the input FS (closed under normal condition,
and opened when water overflow). System operation is according to the following chart:

7. DIAGNOSTIC
With this feature is possible to have a visual signal that a trouble is occurring.
This mode is always active and the signalling is made through the display board LEDS .
In case of no troubles the LEDS status follows its normal function.
NOTES
 The troubles are showed according a priority list that is in case of more than one
trouble present, is always showed, at first, the one with the highest priority (1 23 etc).
 Sensor damaged means a situation where sensor is short-circuited or opened.
 In case of damaged sensors, the system (CM, FMO, FMI etc), if in OFF state, does not start.
 WRONG MODE SELECTED means a situation where the operating mode chosen with remote controller
does not comply with the one allowed by jumpers settings.
