Frequently Asked Questions
How do I choose the right BTU size for my room?
The key figure is the manufacturer’s recommended room size for this unit — you will find it in the product’s technical data. For sun-facing or top-floor rooms, we recommend the next larger capacity class. Our team is happy to advise.
Do I need a certified technician for installation?
Yes — split air conditioners with fluorinated refrigerant must be installed by a certified F-Gas technician (EU Regulation 517/2014). Self-installation is not permitted. Installation is carried out by a certified contractor of your choice.
What warranty is included?
In addition to the statutory legal guarantee, the manufacturer’s warranty applies to the unit in accordance with the manufacturer’s warranty terms, provided installation is carried out by a certified F-Gas technician. Detailed warranty conditions are in the product datasheet.
What do SEER and SCOP mean?
SEER (Seasonal Energy Efficiency Ratio) is the seasonal cooling efficiency — higher is better. SCOP (Seasonal Coefficient of Performance) is the seasonal heating efficiency. SEER ≥ 6.0 and SCOP ≥ 4.0 are considered very good for residential split air conditioners.
