SAFETY STANDARDS AND WARNINGS

U I A

Use the power supply voltage shown on the rating plate. Keep the power switch or plug clean. Connect the power cable correctly and securely to the outlet, avoiding the risk of electric shock or fire due to insufficient contact.

Check that the outlet is suitable for the plug, otherwise have the outlet replaced. Do not use the power switch or pull out the plug to switch the appliance off when operating. This may cause fires due to sparks, etc.

The user must contact qualified personnel to earth the appliance, in compliance with the legislation in force, and to install a thermal-magnetic circuit breaker.

Do not bend, pull or press the power cable, as it may break. Electric shock or fire are usually caused by damaged power cables.

The power cable must only be replaced by specialist technicians.

Do not use power supply cables that are too long, or multiple adapters.

Do not operate the air-conditioner with wet hands; this may cause electric shock.

Do not block the air inlet or outlet of either the indoor or outdoor unit.

Extended exposure to cold air is a health risk.

If smoke or a smell of burning is detected, immediately disconnect power and contact the Service

Centre.

Do not modify or alter the characteristics of the appliance in any way.

Contact the Service Centres authorised by the

Manufacturer for all repairs. Incorrect repair may cause electric shock, etc.

Make sure the appliance is disconnected from the power supply when not used for extended periods, and before performing any cleaning or maintenance operations.

Do not install the appliance in environments where the air may contain gases, oil or sulphur, or near sources of heat.

Check that the base of the outdoor unit is installed securely.

This appliance must only be used by adults; do not allow children to play with the appliance.

Do not climb onto or rest objects on the outdoor unit.

Never insert sticks or tools into the appliance.

This may cause injuries.

2 English 11/2002 SINGLE SPLIT

Lowers the inside temperature by 5°C from the outside temperature

Keep the appliance at least 50cm from flammable substances (alcohol, etc.) or from pressurised containers (e.g. spray cans).

Selecting the most suitable temperature will avoid damaging the appliance.

The direction of air flow must be adjusted correctly. The louvers must be adjusted downwards in heating mode, and upwards in cooling mode.

Do not leave doors and windows open when the air-conditioner is operating for long periods.

Do not aim the air stream directly at plants or animals.

Do not spray water onto the air-conditioner.

This appliance has been designed to air-condition the home and must not be used for other purposes, such as drying clothes, cooling food, etc.

If the appliance is used in areas without the renewal of fresh air, precautions must be taken to prevent any leaks of refrigerant gas from stagnating in the environment and creating the risk of fire.

Do not rest heavy or hot objects on the appliance.

The packing materials are recyclable. It is therefore recommended to place them in suitable containers for separate waste disposal.

At the end of its working life, take the air-conditioner to a special waste disposal centre.

Only use the air-conditioner as shown in this booklet. These instructions are not intended to cover every possible situation that may arise.

Common sense and prudence must be applied in the installation, operation and conservation of all household appliances.

TROUBLESHOOTING

FAULT

The appliance doesn't work

Wait

U I A

POSSIBLE CAUSE

• Once switched off the air-conditioner cannot be started for around 3 minutes

Strange smell

• This smell may come from other sources, such as furniture or the like.

Sound of running water

• This derives from the flow of refrigerant in the air-conditioner, and is not a fault.

The appliance doesn't work

Insufficient cold or hot air produced

The appliance does not respond to the remote control

Immediately switch off the air-conditioner and disconnect the power supply in the event of:

12 English 11/2002

OFF

• This occurs when the air in the room cools down very quickly, for example in “COOLING” or “DEHUMIDIFI-

CATION” mode.

1. INSTALLATION OF THE FASTENING PLATE

Select the position for installing the fastening plate, according to of the location of the indoor unit and the layout of the pipes.

Adjust the level of the fastening plate, using a straightedge or a plumb line.

Make 32mm deep holes in the wall to mount the plate.

Insert the plastic plugs in the holes, then secure the fastening plate using the self-threading screws supplied with the unit.

Check that the fastening plate is securely fitted so as to support a 60kg adult.

Your fastening plate may differ from the one described above, yet the installation procedure is the same.

2. MAKE A HOLE FOR THE PIPES

Choose the location of the hole for the pipes, according to the position of the fastening plate.

Make a hole in the wall. The hole must slope downwards towards the outside.

Place a sleeve through the hole in the wall to protect the wall and keep it clean.

3. INSTALLATION OF THE PIPES ON THE

INDOOR UNIT

Place the pipes (for liquid and gas) through the hole in the wall from the outside, or alternatively from the inside after having completed the installation of the pipes and the connection of the cables on the indoor unit, for connection to the outdoor unit.

Decide whether to remove the plastic segment, according to the direction of the pipes.

When the pipe is fastened along the direction 1, 2 or 4, remove the corresponding plastic segment from the base of the indoor unit.

After having connected the pipes according to the instructions, install the drain hose.Then install the power supply cables. After having completed the connections, wrap the pipes, cables and drain hose in a layer of thermal insulation.

Line the joints of the pipe with thermal insulation and cover them with vinyl tape.

• Position the drain hose under the pipes.

• Insulation material: polythene foam, thickness greater than 6mm.

The drain hose must be supplied by the user.

• The drain hose must run downwards, to assist drainage.

• Do not bend the drain hose, allow it to protrude, twist it or immerse the end in water. If the drain hose is connected to an extension, check that this is thermally insulated when running in the indoor unit.

• If the pipes run to the right, the pipes, the power cable and the drain hose must be thermally insulated and fastened to the rear of the unit by a pipe coupling.

1. Insert the pipe coupling in the opening.

2. Press the pipe coupling to secure it to the base.

Indoor unit

Connect the power cable to the indoor unit by connecting the wires to the terminals on the control panel individually, according to the connection to the outdoor unit.

To make the connection to the indoor unit terminal, remove the console.

Outdoor unit

Remove the access door from the unit by loosening the screw. Connect the wires to the terminal on the control panel with a terminal screw.

Place the access door back in position and tighten the screw.

Use an approved switch between the power supply source and the unit. An isolating device must be fitted to correctly disconnect all the power supply lines.

Use a separate power supply circuit specifically for the air-conditioner. For details on the wiring method, refer to the circuit diagram inside the access door.

Check that the thickness of the cable complies with the specifications of the power supply.

Check the wires and make sure that they are all securely fastened following the connection of the cable.

Make sure an ear th leakage switch is installed in wet or damp areas.

The connection cable between the outdoor and indoor unit must be suitable for outdoor use.

The plug must remain accessible following the installation of the appliance, so that the appliance can be unplugged if required.

1. Install the drain fitting and the drain hose (heat pump model only)

The condensate is drained from the outdoor unit when the appliance operates in heating mode. To avoid disturbing neighbours and to respect the environment, install a drain fitting and a drain hose to convey the condensate. Simply install the drain fitting and the rubber washer on the chassis of the outdoor unit, then connect a drain hose as shown in the figure.

2. Installation and fastening of the outdoor unit

Bolt the unit securely to a level and sturdy floor. If the unit is to be installed on a wall or on the roof, make sure the support is fastened securely to prevent it from moving following intense vibrations or strong winds.

3. Connecting the pipe to the outdoor unit

Remove the cap from the 2- and 3-way valves. Connect the pipes to the 2- and 3-way valves separately, tightening to the torque specified.
