IMPORTANT! Please read before installation
This air conditioning system meets strict safety and operating standards. For the installer or service person, it is important to install or service the system so that it operates safely and efficiently.
For safe installation and trouble-free operation, you must:
• Carefully read this instruction booklet before beginning.
• Follow each installation or repair step exactly as shown.
• Observe all local, state and national electrical codes.
• Pay close attention to all warning and caution notices given in this manual.
•The unit must be supplied with a dedicated electrical line.
This symbol refers to a hazard or unsafe practice which can result in severe personal injury or death.
This symbol refers to a hazard or unsafe practice which can result in personal injury or product or property damage.
If necessary, get help
These instructions are all you need for most installation sites and maintenance conditions. If you require help for a special problem, contact our sale/service outlet or your certified dealer for additional instructions.
In case of improper installation
The manufacturer shall in no way be responsible for improper installation or maintenance service, including failure to follow the instructions in this document.
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 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, 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... ... In a ceiling or wall
Make sure the ceiling/wall 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 than drifting snow. Provide snow vents.
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 testng 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.

6.FUNCTION
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 Heat Mode Operation
The Heating mode operation is similar to the Cooling mode operation. The CM, FMO and FMI are mainly controlled by the value of (RAT – SPT). In the graph above, the FMI is operating in AUTO speed mode. Therefore, the FMI speed changes automatically according to the (RT - SPT).
NOTES
1. After the CM has stopped, the FMI runs for 30s in order to purge heat from the indoor coil.
2. The FMI will not be turned on until the indoor coil temperature is warm enough to prevent the supply of
cool air (see COLD DRAFT PREVENTION feature for details). 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).
HEAT PUMP MODELS
12
6-3 Auto (cool/heat) Mode Operation
In Auto Mode, the unit switches automatically between the Auto Cooling and Auto Heating in order to maintain the room temperature (RAT) at the prescribed set point (SPT). The switching between the two modes is according to the above graph. Refer to the sections 5.1 COOLING MODE and 5.2 HEATING MODE for system operation details.
HEAT PUMP MODELS
13
6-4 Dry Mode Operation

6-5 Fan Mode Operation
With this mode, the indoor fan is turned on while CM, FMO and RV stay off all the time. The user can select between 3 speeds: HIGH, MEDIUM and LOW.
6-6 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
HEATING MODE
2 (SPT - RAT):
HIGH speed
(SPT - RAT) < 2: MEDIUM speed
NOTE
SPT = Set Point Temperature
14
6-7 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
HEATING mod
e
SET POINT temperature = 21°C FAN SPEED = HIGH
6-8 Protection operations in Cool and Dry Mode
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 B 30 seconds OFF).
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
The system exit this protection routine when ICT temperature rises above 8°C.
15
6-9 Protection operations in Heat Mode
5-9.1 Cold draft
This feature prevents the supply of cold air forcing the indoor fan to a speed which cannot be changed by the user. As soon as the protection mode is exited speed can be changed manually through the remote controller. The protection acts in the following
6-9.2 Defrost
The defrost process is controlled by a detection algorithm designed in order to mantain optimal utilization of the heat pump capacity especially during negative outdoor temperature conditions. During DEFROST OPERATION the main components operates according to the following chart:

6-10 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.
6-11 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.
6-12 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

11 CHECKING ELETRICAL COMPONENTS
11-1 Measurement of Insulation Resistance
The insulation is in good condition if the resistance exceeds 1 MOhm
a) Power Supply Wires
Clamp the earthed wire of the power supply wires with the lead clip of the insulation resistance tester and measure the resistance by placing a probe on either of the power wires (fig.1). Then measure the resistance between the earthed wire and the other power wires (fig.1).
b) Unit
Clamp an alluminium plate fin or copper tube with the lead clip of the insulation resistance tester and measure the resistance by placing a probe on N terminal, and then on Lterminal the terminal plate (fig.2)
c) Measurement of Insulation Resistance
for Electrical Parts
Disconnect the lead wires of the disired electric part from terminal plate, PCB assy, capacitor, etc. Similary disconnect the connector. Then measure the insulation resistance (fig.1 to 4). Refer to electric wiring diagram.
NOTE
If the probe cannot enter the poles because the hole is too narrow then use a probe with a thinner pin.
30
11-2 Checking Continuity of fuse on PCB assy
Remove PCB assy from electrical component box (fig.5)
Then pull out the fuse from PCB assy
Check continuity of fuse by the multimeter (fig.6)
11-3 Checking Motor Capacitor
Remove the lead wires from the capacitor terminals, and then place a probe on the capacitor terminals as shown in fig.7. Observe the deflection of the pointer, setting the resistance measuring range of the multimeter to the maximum value. The capacitor is "good" if the pointer bounces to a great extent and the gradually returns to its original position. The range of deflection and deflection time deffer according to capacity of the capacitor.
