GENERAL INFORMATION

SAFETY RULES AND RECOMMENDATIONS FOR THE USER

GENERAL INFORMATION

Read this guide before installing and using the

appliance.

Check that air cannot enter the refrigerant system

and check for refrigerant leaks when moving the air
conditioner.

Carry out a test cycle after installing the air conditio-

ner and record the operating data.

The ratings of the fuse installed in the built-in control

unit are 2.5 A, E, 250V.

The user must ensure that the whole unit is protec-

ted 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 there-

fore 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 Servi-

ce 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 there-

fore 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.

Cleaning and maintenance must be carried out by

specialised technical personnel. In any case discon­nect the appliance from the mains electricity supply
before carrying out any cleaning or maintenance.
