2. Safety Instructions for the User

Always follow the instructions and safety regulations below.

2.1 General

WARNING:

If you are unsure how to operate the unit, contact your installer.

WARNING:

This appliance can be used by children aged 8 years and above and persons with reduced 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 the hazards involved. Children shall not play with the appliance. Cleaning and user maintenance shall not be made by children without supervision.

WARNING:

To prevent electric shock or fire:

• Do NOT wash the unit with water.
• Do NOT service the unit with wet hands.
• Do NOT place any objects containing water on the unit.

CAUTION:

• Do NOT place any objects or equipment on the unit.
• Do NOT sit, climb, or stand on the unit.

Electrical/Electronic Products: These products must not be mixed with unsorted household waste. Do not attempt to dismantle the system yourself: dismantling, refrigerant/oil/parts disposal/recycling MUST be performed by an authorized installer and comply with applicable legislation.

Batteries: Batteries are marked with the following symbol [battery symbol]. This means batteries must not be mixed with unsorted household waste. If a chemical symbol is printed below the symbol, it means the battery contains a heavy metal above a certain concentration (e.g., Pb: lead (>0.004%)). Used batteries MUST be recycled at a specialized recycling facility.

2.2 Recommendations for Safe Operation

WARNING: A2L REFRIGERANT: MODERATELY FLAMMABLE SUBSTANCE

The refrigerant in this unit is moderately flammable.

CAUTION:

The indoor unit contains radio equipment. The minimum distance between the radiating part of the equipment and the user is 10 cm.

CAUTION:

Do NOT insert fingers, rods, or other objects into the air inlet and outlet openings. When the fan rotates at high speed, it can cause injury.

WARNING:

Do NOT modify, disassemble, move, reinstall, or repair the unit yourself, as incorrect dismantling or installation may cause electric shock or fire. Contact your supplier.

In case of accidental refrigerant leakage, ensure there are no open flames nearby. The refrigerant itself is harmless, non-toxic, and moderately flammable, but it will generate toxic gas if it leaks into a room where flammable air from fan heaters, gas boilers, etc., is present. Always ask a qualified technician to confirm that the leak area has been repaired before resuming operation.

CAUTION:

ALWAYS use the wireless remote control or other user interface (if applicable) to adjust the position of the flaps and louvers. If the flaps and louvers rotate and you move them by force by hand, the mechanism will break.

CAUTION:

NEVER expose small children, plants, or animals to the direct airflow of the air conditioner.

WARNING:

Do NOT place a spray can containing flammable substances near the air conditioner and do NOT use sprays around the unit. This could lead to fire.

CAUTION:

Do NOT operate the system when using a fumigating insecticide in the room. This may cause chemicals to deposit in the unit, which could be hazardous to the health of people who are sensitive to chemicals.

WARNING:

• The refrigerant in the system is safe and normally does NOT leak. If refrigerant leaks into the room and comes into contact with fire from a burner, radiator, or heater, it may cause fire or harmful gas.
• Turn off all flammable heating appliances, ventilate the room, and contact the dealer from whom you purchased the unit.
• Do NOT use the unit until a service technician confirms that the leak area has been repaired.

WARNING:

• Do NOT puncture or incinerate parts of the refrigerant circuit.
• Do NOT use cleaning materials or defrosting accelerators other than those recommended by the manufacturer.
• Note that the refrigerant inside the system is odorless.

WARNING:

The unit must be stored so that it is protected from mechanical damage and in a well-ventilated space free from continuously operating ignition sources (e.g., open flames, gas appliances, electric heaters). The room size must correspond to that specified in the "General Safety Measures".

DANGER: RISK OF ELECTRIC SHOCK

Before cleaning the air conditioner or air filter, stop its operation and TURN OFF the power supply. Otherwise, electric shock and injury may occur.

CAUTION:

After prolonged use, check the unit's mounting for any damage. Such damage may lead to the unit falling and causing injury.

CAUTION:

Do NOT touch the heat exchanger fins. These fins are sharp and may cause injury.

WARNING:

Be careful with ladders when working at height.

WARNING:

Incorrect cleaning agents or procedures may cause damage to plastic components or water leakage. Spraying cleaning agents onto electrical components, such as motors, may cause damage, smoke, or fire.

DANGER: RISK OF ELECTRIC SHOCK

Before cleaning, ensure that the unit is turned OFF and the power cord plug is removed from the outlet. Otherwise, electric shock and injury may occur.

WARNING:

Stop the unit and TURN OFF the power supply if anything unusual occurs (e.g., burning smell). Leaving the unit in such circumstances may cause damage, electric shock, or fire. Contact your supplier.

WARNING:

If the power cord is damaged, it MUST be replaced by the manufacturer, its service agent, or similarly qualified persons to avoid hazards.

WARNING: A2L REFRIGERANT: MODERATELY FLAMMABLE SUBSTANCE

The refrigerant in this unit is moderately flammable.

CAUTION:

7. Maintenance and Service

7.1 Overview: Maintenance and Servicing

The installer must perform annual maintenance.

Refrigerant: This product contains fluorinated greenhouse gases that contribute to global warming. Do NOT release gases into the atmosphere. Refrigerant Type: R32. Global Warming Potential (GWP): 675.

CAUTION: Applicable legislation regarding fluorinated greenhouse gases requires refrigerant charging to be indicated both by weight and by CO2 equivalent. Formula for calculating greenhouse gas emissions, expressed in tonnes of CO2 equivalent: GWP of refrigerant × Total amount of refrigerant charged [in kg]/1000.

For more information, contact your installer.

CAUTION:

Maintenance MUST be performed by an authorized installer or service representative. Annual maintenance is recommended. However, applicable legislation may require shorter maintenance intervals.

WARNING:

Do NOT puncture or incinerate parts of the refrigerant circuit. Do NOT use cleaning materials or defrosting accelerators other than those recommended by the manufacturer. Note that the refrigerant inside the system is odorless.

WARNING:

The unit must be stored so that it is protected from mechanical damage and in a well-ventilated space free from continuously operating ignition sources (e.g., open flames, gas appliances, electric heaters). The room size must correspond to that specified in the "General Safety Measures".

DANGER: RISK OF ELECTRIC SHOCK

Before cleaning the air conditioner or air filter, stop its operation and TURN OFF the power supply. Otherwise, electric shock and injury may occur.
