The split air conditioner Quick Connect creates a comfortable room temperature, even on hot summer days. With the help of the built-in inverter heat pump, the air conditioner can both cool your room in summer and heat it on colder days.

thanks to the powerful 18,000 BTU and the pre-filled R32 coolant, every room can be cooled down to your desired temperature within a very short time. The air conditioning remains very quiet . With the sleep function, it also runs particularly quietly at night. With a volume of only 19 dB, the indoor unit is then hardly perceptible and you can enjoy a peaceful and restful sleep.

Our air conditioners are equipped with high-quality filters, what a pleasant room climate cares. Activated carbon filters are essential for eliminating unpleasant odours, gases and nicotine smoke. It also collects smaller dust particles and prevents allergies and the spread of pollen. In the further filtering process, bacteria, fungi and microbes are destroyed.

The indoor unit has a automatic self-cleaning and protects itself from viruses, bacteria & mold with the help of this process. This prevents unpleasant odors. The heat exchanger is by high quality and durable TitanGold® particularly corrosion-resistant. This protects the air conditioner from rusting and provides optimal performance. This increases the longevity of your air conditioning system and improves the indoor climate.

With the pre-installed WIFI module , you can connect the air conditioner to the smart home so that you can conveniently and flexibly control the temperature from anywhere using Alexa, Google Home or our app. Since the same smart chip is installed in our products, several air conditioners can also be used in one app or via the smart home being controlled.

Setup and commissioning are particularly easy. Thanks to the included Quick Connector CU pipe & the power connection will no vacuum pump required for the installation of the system. This saves a technician a lot of work and he can therefore install and commission the air conditioning system in a short time.

Super schnell und super ware alles bestens
Immer wieder.

Rundum Sorglos Paket

Die Klimaanlage lässt sich problemlos von einem halbwegs technisch versierten Menschen installieren. Toll ist, das man keine Vakuum Anlage benötigt. Die Beschreibung könnte etwas ausführlicher bezüglich Installation sein. Durch die Vorevakuirten Leitungen wäre es schön wenn die Anlage mit verschiedenen Längen bestellt werden könnte (Leitungen können nicht gekürzt werden).
Ansonsten alles super und sehr leise 👍👍

Josef Oswald

Die Klimaanlage ist relativ einfach zu installieren und funktioniert ausgezeichnet.
Schade ist, dass die Installationsanweisung anscheinend veraltet ist und nicht zu der gelieferten Anlage passt. Dort werden Schritte beschreiben, die gar nicht notwendig sind, da alles (z. B. Elektro) sehr gut vorinstalliert ist. Ein Nachteil sind auch die langen Verbindungsrohre zwischen Innen- und Außengeräte (5m). Wenn man kurze Entfernungen zwischen beiden Geräten hat tut man sich schwer die langen Leitungen unterzubringen. Hier wäre ein Angebot mit verschiedenen Längen vorteilhaft und würde vermutlich auch Material sparen.
Alles in allem bin ich sehr zufrieden und würde mich wieder für den Kauf entscheiden.

Excellent produit

Produit de très bonne qualité et facile à installer. Merci beaucoup
