2 User safety instructions
Always observe the following safety instructions and regulations.
2.1 Instructions for safe operation WARNING: MILDLY FLAMMABLE MATERIAL The refrigerant inside this unit is mildly flammable.

Operation manual

FTXJ-A(W)(S)(B)9 Daikin room air conditioner 3P728539-11M ­ 2024.07

CAUTION
The indoor unit contains radio equipment, minimum separation 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 or outlet. When the fan is rotating at high speed, it will cause injury.
WARNING
 Do NOT modify, disassemble, remove, reinstall or repair the unit yourself as incorrect dismantling or installation may cause an electrical shock or fire. Contact your dealer.
 In case of accidental refrigerant leaks, make sure there are no naked flames. The refrigerant itself is entirely safe, non-toxic and mildly flammable, but it will generate toxic gas when it accidentally leaks into a room where combustible air from fan heaters, gas cookers, etc. is present. Always have qualified service personnel confirm that the point of leakage has been repaired or corrected 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. When the flaps and louvers are swinging and you move them forcibly by hand, the mechanism will break.
CAUTION
NEVER expose little children, plants or animals directly to the airflow.
WARNING
Do NOT place a flammable spray bottle near the air conditioner and do NOT use sprays near the unit. Doing so may result in a fire.
FTXJ-A(W)(S)(B)9 Daikin room air conditioner 3P728539-11M ­ 2024.07

2 User safety instructions
CAUTION Do NOT operate the system when using a room fumigation-type insecticide. Chemicals could collect in the unit, and endanger the health of people who are hypersensitive to chemicals.
WARNING  The refrigerant inside the unit is
mildly flammable, but normally does NOT leak. If the refrigerant leaks in the room and comes in contact with fire from a burner, a heater, or a cooker, this may result in fire, or the formation of a harmful gas.  Turn OFF any combustible heating devices, ventilate the room, and contact the dealer where you purchased the unit.  Do NOT use the unit until a service person confirms that the part from which the refrigerant leaked has been repaired.
WARNING  Do NOT pierce or burn refrigerant
cycle parts.  Do NOT use cleaning materials or
means to accelerate the defrosting process other than those recommended by the manufacturer.  Be aware that the refrigerant inside the system is odourless.
WARNING The appliance shall be stored so as to prevent mechanical damage and in a well-ventilated room without continuously operating ignition sources (e.g. open flames, an operating gas appliance, or an operating electric heater). The room size shall be as specified in the General safety precaution.

3 About the system
DANGER: RISK OF ELECTROCUTION To clean the air conditioner or air filter, be sure to stop operation and turn all power supplies OFF. Otherwise, an electrical shock and injury may result.
CAUTION After a long use, check the unit stand and fitting for damage. If damaged, the unit may fall and result in injury.
CAUTION Do NOT touch the heat exchanger fins. These fins are sharp and could result in cutting injuries.
WARNING Be careful with ladders when working in high places.
WARNING Improper detergents or cleaning procedure may cause damage on plastic components or water leakage. Splashed detergent on electric components, such as motors, may cause failure, smoke or ignition.
DANGER: RISK OF ELECTROCUTION Before cleaning, be sure to stop the operation, turn the breaker OFF or pull out the supply cord. Otherwise, an electrical shock and injury may result.
WARNING Stop operation and shut OFF the power if anything unusual occurs (burning smells etc.). Leaving the unit running under such circumstances may cause breakage, electrical shock or fire. Contact your dealer.

CAUTION The indoor unit contains radio equipment, minimum separation distance between the radiating part of the equipment and the user is 10 cm.
NOTICE Do NOT use the system for other purposes. In order to avoid any quality deterioration, do NOT use the unit for cooling precision instruments, food, plants, animals, or works of art.
3.1 Indoor unit
CAUTION Do NOT insert fingers, rods or other objects into the air inlet or outlet. When the fan is rotating at high speed, it will cause injury.
INFORMATION The sound pressure level is less than 70 dBA.
WARNING  Do NOT modify, disassemble, remove, reinstall or repair the unit yourself as incorrect dismantling or installation may cause an electrical shock or fire. Contact your dealer.
 In case of accidental refrigerant leaks, make sure there are no naked flames. The refrigerant itself is entirely safe, non-toxic and mildly flammable, but it will generate toxic gas when it accidentally leaks into a room where combustible air from fan heaters, gas cookers, etc. is present. Always have qualified service personnel confirm that the point of leakage has been repaired or corrected before resuming operation.

7 Maintenance and service
7.1 Overview: Maintenance and service
The installer has to perform a yearly maintenance. Periodical inspections for refrigerant leaks may be required depending on the applicable legislation. Contact your installer for more information.
About the refrigerant This product contains fluorinated greenhouse gases. Do NOT vent gases into the atmosphere. Refrigerant type: R32 Global warming potential (GWP) value: 675
NOTICE Applicable legislation on fluorinated greenhouse gases requires that the refrigerant charge of the unit is indicated both in weight and CO2 equivalent. Formula to calculate the quantity in CO2 equivalent tonnes: GWP value of the refrigerant × total refrigerant charge [in kg]/1000 Contact your installer for more information.
NOTICE Maintenance MUST be done by an authorised installer or service agent. We recommend performing maintenance at least once a year. However, applicable legislation might require shorter maintenance intervals.

WARNING  The refrigerant inside the unit is mildly flammable, but normally does NOT leak. If the refrigerant leaks in the room and comes in contact with fire from a burner, a heater, or a cooker, this may result in fire, or the formation of a harmful gas.
 Turn OFF any combustible heating devices, ventilate the room, and contact the dealer where you purchased the unit.
 Do NOT use the unit until a service person confirms that the part from which the refrigerant leaked has been repaired.
WARNING  Do NOT pierce or burn refrigerant cycle parts.
 Do NOT use cleaning materials or means to accelerate the defrosting process other than those recommended by the manufacturer.
 Be aware that the refrigerant inside the system is odourless.
WARNING The appliance shall be stored so as to prevent mechanical damage and in a well-ventilated room without continuously operating ignition sources (e.g. open flames, an operating gas appliance, or an operating electric heater). The room size shall be as specified in the General safety precaution.
DANGER: RISK OF ELECTROCUTION To clean the air conditioner or air filter, be sure to stop operation and turn all power supplies OFF. Otherwise, an electrical shock and injury may result.
WARNING To prevent electrical shocks or fire:
 Do NOT rinse the unit.
 Do NOT operate the unit with wet hands.
 Do NOT place any objects containing water on the unit.
CAUTION After a long use, check the unit stand and fitting for damage. If damaged, the unit may fall and result in injury.
CAUTION Do NOT touch the heat exchanger fins. These fins are sharp and could result in cutting injuries.
WARNING Be careful with ladders when working in high places.
7.2 To clean the indoor unit and wireless remote control
WARNING Improper detergents or cleaning procedure may cause damage on plastic components or water leakage. Splashed detergent on electric components, such as motors, may cause failure, smoke or ignition.
DANGER: RISK OF ELECTROCUTION Before cleaning, be sure to stop the operation, turn the breaker OFF or pull out the supply cord. Otherwise, an electrical shock and injury may result.
