SAFETY RULES AND RECOMMENDATIONS FOR USE
PROHIBITION

Never switch on or off the circuit breaker or touch the buttons with wet hands. You may be shocked.

Do not insert your fingers or other objects into the air inlet / outlet grilles.

Do not insert any object or liquid (metal object, piece of paper, water, etc.) into the air inlet or outlet grille. The internal
blower (which can rotate at high speed) or the high voltage sections can cause injury or electric shock.

Do not clean the inside of the air conditioner yourself. Ask your dealer to clean the air conditioner internally. Improper
cleaning can result in breakage of resin parts or deterioration of the insulation of electrical components, which may
result in water leakage, electric shock or fire.

Do not place heavy objects on the power cable, expose it to heat, or pull on it. Otherwise, there is a risk of electric shock
or fire.

Do not use any other refrigerant than the one specified. Otherwise, abnormally high pressure may occur in the
refrigeration cycle, which can lead to product malfunction, explosion or even personal injury.

Do not bend, pull or crush the power cord as this may damage it.

Electric shocks and fires are usually caused by a damaged power cord. Only a qualified technician should replace a
damaged power cord.

Do not use an extension cord or multiple plug.

Do not touch the device if parts of your body are humid or wet.

Do not obstruct the air inlet or outlet of the wall unit or outdoor unit.

Clogging of these openings could cause a decrease in the efficiency of the air conditioner with the possibility of
subsequent failures.

Do not alter the characteristics of the device in any way.

Do not install the unit in an environment that may contain gasoline, oil, or sulfur or near a heat source.

Do not climb, do not place heavy or hot objects on the top of the unit.

Do not leave doors or windows open for extended periods while the air conditioner is running.

Do not direct the air flow onto plants or animals.

Prolonged direct exposure to the cold air conditioner could have a negative effect on plants or animals.

Do not put the air conditioner in contact with water. Electrical insulation could be damaged and cause a risk of electric
shock.

Do not climb or place objects on the outdoor unit.

Never insert a stick or similar object into the outdoor unit. You could be seriously injured.
WARNING

The manufacturer declines all responsibility for damage caused by non-observance of the safety instructions in this user
manual.

Be careful not to install, repair, open or remove the cabinet. You may be exposed to dangerous voltages. Ask the dealer
or a professional to do so.

Always use the air conditioner with the air filter in place. Use without the air filter could cause excessive accumulation
of dust and other residues on the internal components resulting in subsequent failures.

The fins should be down in heating mode and up in cooling mode.

Selecting the most appropriate temperature may prevent damage to the unit.

Do not expose your body directly to cold or hot air for a long time.

In the event of a malfunction (burning smell, etc.), switch off the air conditioner and switch off the circuit breaker.

Be careful not to disassemble, modify or move the device yourself. You may cause a fire, electric shock, or water leak.
If the cables are damaged, there is a risk of electric shock or fire. Always contact your dealer to repair or move the unit,

If a malfunction occurs (especially if there is a burning smell from the unit or the unit is no longer cooling), immediately
stop using the unit and turn off the circuit breaker. If you continue to use the product under these conditions, you may
be subjected to electric shock or fire. Always contact your dealer to repair or have the device inspected,

Do not connect the ground wire to a gas pipe, water pipe, lightning rod or to the telephone earth line.

If the drain hose of the indoor unit is exposed due to moving the unit, close the opening.

Do not touch the internal electrical components as this may result in electric shock or injury.

If the air conditioner does not cool or heat up, it is possible that refrigerant leakage has occurred. Contact your dealer.
The refrigerant used in the air conditioner is well protected. It will not leak under normal conditions of use. Nevertheless,
if a leak occurs and the fluid comes into contact with a heat source, especially with a radiator or a range, a harmful
reaction can take place.
