About the system
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.
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 eaters, gas cookers, etc. is present. Always have qualified service personnel confirm that the point of leakage has been repaired or corrected before resuming operation.

Operation range
Use the system in the following temperature and humidity ranges for safe and effective operation.
| Operation mode | Operation range |
|---|---|
| Cooling(a)(b) |
- Outdoor temperature: –10~48°C DB
- Indoor temperature: 18~32°C DB
- Indoor humidity: ≤80%
Heating(a)|
- Outdoor temperature: –15~24°C DB
- Indoor temperature: 10~30°C DB
Drying(a)|
- Outdoor temperature: –10~48°C DB

(a) A safety device might stop the operation of the system if the unit
runs outside its operation range.
(b) Condensation and water dripping might occur if the unit runs outside
its operation range.
Operation mode and temperature set point
When. Adjust the system operation mode and set the temperature when you want to:
- Heat up or cool down a room
- Blow air in a room without heating or cooling
- Decrease the humidity in a room
What. The system operates differently, depending on the user selection.
Additional info:
- Outside temperature. The system’s cooling or heating effect decreases when the outside temperature is too high or too low.
▪ Defrost operation. During heating operation, frost might occur on the outdoor unit and decrease the heating capacity. In that case, the system automatically switches to defrosting operation to remove the frost. During defrosting operation, hot air is NOT blown from the indoor unit.

#### Energy saving and optimum operation
##### Econo operation
This is a function which enables efficient operation by limiting the maximum
power consumption value. This function is useful for cases in which attention
should be paid to ensure a circuit breaker will not trip when the product runs
alongside other appliances.
**INFORMATION**
* Powerful and Econo operation CANNOT be used at the same time. The last selected function takes priority.
* Econo operation reduces power consumption of the outdoor unit by limiting the rotation speed of the compressor. If power consumption is already low, Econo operation will NOT further reduce power consumption.

#### Maintenance and service
##### Overview: Maintenance and service
The installer has to perform a yearly maintenance.
**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.
Please contact your installer for more information.
**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 in a room without continuously operating ignition sources (example: open flames, an operating gas appliance or an operating electric
heater).
**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.
**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.
**NOTICE**
* Do NOT use gasoline, benzene, thinner, polishing powder or liquid insecticide. **Possible consequence** : Discoloration and deformation.
* Do NOT use water or air of 40°C or higher. **Possible consequence** : Discoloration and deformation.
* Do NOT use polishing compounds.
* Do NOT use a scrubbing brush. **Possible consequence** : The surface finishing peels off.
