1.0. SAFETY INSTRUCTIONS
Read the following safety instructions before installing the unit or doing service work.
NOTE This is used to communicate installation, operation, maintenance
or servicing information that is important but not hazard related.
This symbol indicates a potentially hazardous situation that, if
not avoided, will or can cause minor personal injury or property
damage.
CAUTION
▪ Read this guide before installing and using the
appliance.
▪ During the installation of the indoor and outdoor
units the access to the working area should
be forbidden to children. Unforeseeable acci-
dents could happen.
▪ Make sure that the base of the outdoor unit is
rmly xed.
▪ 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
conditioner and record the operating data.
▪ The ratings of the fuse installed in the built-in
control unit are T 5 A / 250 V.
▪ The user must protect the indoor unit with a
fuse of suitable capacity for the maximum in-
put current or with another overload protection
device.
▪ Check that the socket is suitable for the plug,
otherwise have the socket changed.
▪ The appliance must be tted with means for
disconnection from the supply mains having a
contact separation in all poles that provide full
disconnection under overvoltage category III
conditions, and these means must be incor-
porated in the xed wiring in accordance with
the wiring rules.
▪ The air conditioner must be installed by pro-
fessional or qualied persons.
▪ Do not try to install the air conditioner
alone. Always contact specialized technical
personnel.
▪ Cleaning and maintenance must be carried
out by specialized technical personnel. In
any case disconnect the appliance from the
mains electricity supply before carrying out
any cleaning or maintenance.
▪ Ensure that the mains voltage corresponds
to that stamped on the rating plate. Keep the
switch and power plug clean. Insert the power
plug correctly and rmly into the socket,
thereby avoiding the risk of electric shock or
re due to insufcient contact.
▪ Do not pull out the plug to switch off the appli-
ance when it is in operation, since this could
create a spark and cause a re, etc.
▪ This appliance has been made for air condi-
tioning domestic environments and must not
be used for any other purpose, such as for
drying clothes, cooling food, etc.
This symbol indicates a potentially hazardous situation that, if not
avoided, can cause severe personal injury, death, or substantial
property damage.
WARNING
This symbol indicates an imminently hazardous situation that, if
not avoided, will cause severe personal injury, death, or substan-
tial property damage.

1.0. SAFETY INSTRUCTIONS
▪ The packaging materials are recyclable and
should be disposed of in separate waste bins.
Take the air conditioner at the end of its life
to an authorized waste collection center for
disposal.
▪ Always use the appliance with the air lter
mounted. The use of the air conditioner with-
out air lter could cause an excessive accu-
mulation of dust or waste on the inner parts of
the device with possible subsequent failures.
▪ The user is responsible for having the appli-
ance installed by a qualied technician, who
must check that it is earthed in accordance
with current legislation and insert a thermo-
magnetic circuit breaker.
▪ Do not install the appliance at a distance of
less than 50 cm (20 in) from inammable sub-
stances (alcohol, etc.) or from pressurized
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 creat-
ing a danger of re
▪ 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.
▪ Installation must be preformed in accordance
with the requirements of NEC and CEC by au-
thorized personnel only.
▪ This appliance can be used by children aged
from 8 years and above and persons with re-
duced physical, sensory or mental capabilities
or lack of experience and knowledge if they
have been given supervision or instruction
concerning use of the appliance in a safe
way and understand thehazards involved.
Children shall not play with the appliance.
Cleaning and user maintenance shall not be
made by children without supervision.
▪ The batteries in the remote control must be
recycled or disposed of properly. Please dis-
pose of batteries at a municipal collection
point for special waste.
▪ Never remain directly exposed to the ow of
cold air for a long time. The direct and pro-
longed exposition to cold air could be danger-
ous for your health. Particular care should be
taken in the rooms where there are children,
old or sick people.
▪ If the appliance gives off smoke or there is a
smell of burning, immediately cut off the power
supply and contact an authorized service cen-
ter. The prolonged use of the device in such
conditions could cause re or electrocution.
▪ Have repairs carried out only by an authorized
Service Center. Incorrect repair could expose
the user to the risk of electric shock, etc.
▪ Unhook the automatic switch if you foresee
not using the device for a long time.
▪ The airow direction must be properly ad-
justed. The aps must be directed downwards
in the heating mode and upwards in the cool-
ing mode.
▪ Only use the air conditioner as instructed in
this booklet. These instructions are not in-
tended to cover every possible condition and
situation. As with any electrical household
appliance, common sense and caution are
therefore always recommended for installa-
tion, operation and maintenance.
▪ Ensure that the appliance is disconnected
from the power supply when it is not used for
a long period of time and before carrying out
any cleaning or maintenance.
▪ Selecting the most suitable temperature can
prevent damage to the appliance.
CAUTION

1.0. SAFETY INSTRUCTIONS
▪ Do not bend, tug or compress the power cord
as this could damage it. Electrical shocks can
be caused by a damaged power cord. A dam-
aged power cord must only be replaced by
qualied technical personnel.
▪ Do not use extension cords, power strips or
wall adapters.
▪ Do not touch the appliance when barefoot or
parts of the body are wet or damp.
▪ Do not obstruct the air inlet or outlet of the
indoor or the outdoor unit. The obstruction of
these openings can cause a reduction in the
operative efciency of the air conditioner with
possible consequent failures or damages.
▪ The characteristics of the appliance must not
be changed under any circumstances.
▪ Do not install the appliance in environments
where the air could contain gas, oil or sulphur
or near sources of heat.
▪ This appliance is not intended for use by per-
sons (including children) with reduced phys-
ical, sensory or mental capabilities, or lack
of experience and knowledge, unless they
have been given supervision or instruction
concerning use of the appliance by a person
responsible for their safety.
▪ Do not climb onto or place any heavy or hot
objects on top of the appliance.
▪ Do not leave windows or doors open when the
air conditioner is operating.
▪ Do not direct the air onto plants or animals.
A long direct exposition to cold air of the con-
ditioner could have negative effects on them.
▪ Do not put the air conditioner in contact with
water. The electrical insulation could be dam-
aged and thus causing electrocution.
▪ Do not climb onto or place any objects on the
outdoor unit
▪ Never insert your nger, a stick, etc. into the
air inlet/outlet. Doing so could cause injury.
▪ Children should be supervised to ensure that
they do not play with the appliance.
▪ If the power cord is damaged, it must be re-
placed by the manufacturer, its service agent
or similarly qualied persons in order to avoid
a hazard.
