The user must ensure that the whole unit is protec­ted by a fuse of adequate capacity in relation to the maximum input current or by another overload pro­tective device.
Ensure that the mains voltage corresponds to that stamped on the rating plate. Keep the switch or power plug clean. Insert the power plug correctly and firmly into the socket, thereby avoiding the risk of electric shock or fire due to insufficient contact.
Check that the socket is suitable for the plug, otherwise have the socket changed.
Make sure that the base of the outdoor unit is firmly fixed.
Do not install the appliance at a distance of less than 50 cm from inflammable substances (alcohol, etc.) or from pressurised containers (e.g. spray cans).
If the appliance is used in areas without the possibility of ventilation, precautions must be taken to prevent any leaks of refrigerant gas from remaining in the environ­ment and creating a danger of fire
The packaging materials are recyclable and should there­fore be disposed of in the relative separate waste bins. Take the air conditioner at the end of its useful life to a special waste collection centre for disposal.
Only use the air conditioner as instructed in this booklet. These instructions are not intended to cover every possible condition and situation. As with any electrical household appliance, common sense and caution are therefore always recommended for installation, operation and maintenance.
The appliance must be installed in accordance with applicable national regulations.
Before accessing the terminals, all the power circuits must be disconnected from the power supply.
Ensure that the mains voltage corresponds to that stamped on the rating plate. Keep the switch or power plug clean. Insert the power plug correctly and firmly into the socket, thereby avoiding the risk of electric shock or fire due to insufficient contact.
Do not pull out the plug to switch off the appliance when it is in operation, since this could create a spark and cause a fire, etc.
The user is responsible for having the appliance installed by a qualified technician, who must check that it is earthed in accordance with current legisla­tion and insert a thermomagnetic circuit breaker.
Prolonged exposure to cold air is harmful to health.
If the appliance gives off smoke or there is a smell of burning, immediately cut off the power supply and contact the Service Centre.
Have repairs carried out only by an authorised Servi­ce Centre of the manufacturer. Incorrect repair could expose the user to the risk of electric shock, etc.
Ensure that the appliance is disconnected from the power supply when it will remain inoperative for a long period and before carrying out any cleaning or maintenance.
This appliance must only be used by adults; do not allow children or persons with reduced psycho­physical-sensorial abilities to use it.
Selecting the most suitable temperature can prevent damage to the appliance.
The airflow direction must be properly adjusted. The flaps must be directed downwards in the heating mode and upwards in the cooling mode.
This appliance has been made for air-conditioning domestic environments and must not be used for any other purpose, such as for drying clothes, cooling food, etc.
The packaging materials are recyclable and should there­fore be disposed of in the relative separate waste bins. Take the air conditioner at the end of its useful life to a special waste collection centre for disposal.
Only use the air conditioner as instructed in this booklet. These instructions are not intended to cover every possible condition and situation. As with any electrical household appliance, common sense and caution are therefore always recommended for installation, operation and maintenance.

Before starting installation, decide on the position of the indoor and outdoor units, taking into account the mini­mum clearance required around the units (see technical data table).
Install the indoor unit in the room to be air conditioned, avoiding installations in corridors or communal areas.
Install the indoor unit at a height of at least
2.5 m from the ground.
To install, proceed as follows:
Installation of the mounting plate
- Drill 32 mm deep holes in the wall for fixing the plate;
- insert the plastic anchors into the hole;
- fix the mounting plate using the self-tapping screws pro­vided;
- check that the mounting plate is correctly fixed;
- using a spirit level, check that it is level.
Drilling a hole in the wall for the piping
- Decide where to drill the hole in the wall for the piping
(if necessary) according to the position of the mounting plate;
- install a flexible flange through the hole in the wall to
keep the latter intact and clean.
The hole must slope downwards towards the exterior.
Installing the refrigerant, electrical and condensate drainage pipes
- Pass the pipe (for liquids and gas) through the hole in
the wall from the exterior or install it from the indo­or side, after having laid the pipes and connected the cables to the indoor unit, ready for connection to the outdoor unit. Decide whether or not to remove the knockout accor­ding to the direction of the piping.
Water connections
Before installing the air conditioner, choose the direc­tion for the pipes to exit; they may be arranged along any one of the 4 directions shown in the figure:

Lagging
Covered by vinyl tape
Lagging the pipes
Place the drain hose (not provided in the kit) below the piping, taking care not to create siphons.
Use polythene foam with thickness exceeding 6 mm to insulate the connections.
The drain hose must slant downwards to aid drainage.
Do not bend the drain hose or leave it protruding or twisted and do not put the end of it in water. If an extension is connected to the drain hose, ensure that it is lagged when it passes into the indoor unit.
If the piping is installed to the right, the pipes, power cable and drain hose must be lagged and secured onto the rear of the unit with a pipe connection.
1. Insert the pipe connection into the relative slot.
2. Press to join the pipe connection to the base.
Connecting the pipes
Use two wrenches to tighten the indoor unit pipe joints.
Pay particular attention to the torque recommended below in order not to risk deforming and damaging flared pipes, connectors and nuts.
Tighten the connections using two wrenches wor­king in opposite directions (see technical data table).
Attach at this point
After having connected the pipe according to the instruc­tions, install the drain hose. Now install the power cables. After connection, lag the pipe, cables and drain hose with the insulating material.
Lag the pipe joints with insulating material, securing it with vinyl tape.
Cover the through holes in the wall with elastic material that is also noise absorbing if possible.
Upon completion of installation, check that the con­densate flows out regularly.

INSTALLING THE OUTDOOR UNIT
Location
Use bolts to secure the unit to a flat, solid floor.
When mounting the unit on a wall or the roof, make sure the support is firmly secured so that it cannot move in the event of intense vibrations or a strong wind.
Do not install the outdoor unit in pits or air vents
Installing the pipes
Use suitable connecting pipes and equipment for the
refrigerant in the appliance (see rating plate).
The refrigerant pipes must not exceed the maximum
lengths given in the technical data table.
Lag all the refrigerant pipes and joints.
Tighten the connections using two wrenches working
in opposite directions.
Install the drain fitting and the drain hose (for
model with heat pump only)
Condensation is produced and flows from the outdoor unit when the appliance is operating in the heating mode. In order not to disturb neighbours and to respect the environment, install a drain fitting and a drain hose to channel the conden­sate water. Install the drain fitting and rubber washer on the outdoor unit chassis and connect a drain hose to it as shown in the figure.
Do not install the outdoor unit where it is exposed
to sunlight.
Ensure that the recommended space is left around
the appliance.

BLEEDING
INSTALLER
Humid air left inside the refrigerant circuit can cause com-
pressor malfunction. After having connected the indoor
and outdoor units, bleed the air and humidity from the
refrigerant circuit using a vacuum pump.
(1) Unscrew and remove the caps from the 2-way and
3-way valves. (2) Unscrew and remove the cap from the service valve. (3) Connect the vacuum pump hose to the service valve. (4) Operate the vacuum pump for 10-15 minutes until an
absolute vacuum of 10 mm Hg has been reached. (5) With the vacuum pump still in operation, close the
low-pressure knob on the vacuum pump coupling. Stop
the vacuum pump. (6) Open the 2-way valve by 1/4 turn and then close it
after 10 seconds. Check all the joints for leaks using
liquid soap or an electronic leak device. (7) Turn the body of the 2-way and 3-way valves. Discon-
nect the vacuum pump hose. (8) Replace and tighten all the caps on the valves.

RECOMMENDATIONS FOR CORRECT DISPO­SAL OF THE PRODUCT PURSUANT TO EURO­PEAN DIRECTIVE 2002/96/EC
At the end of its useful life the product must not be dispo­sed of together with municipal waste. It may be taken to special centres for separately collected fractions set up by municipal authorities or to dealers that provide this service. By disposing of a household electrical appliance separately, it is possible to avoid potential negative consequences for the environment and for health due to unsuitable disposal. It also allows the component materials to be recovered with consequent important saving of energy and resources. To show the obligation to dispose of the household electri­cal appliances separately, the product bears the symbol of the crossed-out wheeled bin.
Pursuant to Regulation (EC) 842/2006 on certain fluorina­ted greenhouse gases, it is compulsory to:
- fill in the label accompanying the unit, inserting the total quantity of refrigerant charged during installation;
- apply the label next to the technical label applied on the unit;
- cover the label with the provided protective adhesive;
Use an indelible pen.
