KAYSUN Casual Single Room Air Conditioning System for Heating and Cooling - 2.6kW to 7kW
The Casual range has been designed with value for money in mind. It is the entry level system in the Kaysun residential range but don't make the mistake in thinking that the quality has been compromised. There are some features on the Prodigy, Onnix, and Sensation that you won't find on the Casual (mostly install and design related), but if you are looking for a simple to control single room air conditioner that will efficiently heat and cool, the Casual is the perfect unit for you.
Installing your KAYSUN air conditioner
The Aircare team want to make air conditioning as accessible as possible to homeowners and DIYers, with the FGAS regulations in mind. We have made the copper pipe with the electrical cable, and the condensate pipe available as an option to add to your order. Most of our residential customers are looking to save money on sourcing the equipment themselves with intentions to install the hardware, either themselves or by the builder. You will need an FGAS engineer on standby to come and commission the unit once it is in place. Simply:
- Hang the indoor unit in the desired location
- Place the outdoor unit
- Route the pipework and inter-connecting electrical cable from the indoor to the outdoor
- Consider if you need a pump for the condensate or whether you can go straight out through the wall via gravity drain.
- Have an Electrician provide the 240v power to the outdoor unit usually with a switch isolator
- Call your refrigeration Engineer to have them commission the unit for you (done from the outside).

Drop Down Options Explained
We aim to make your project as easy as possible, and cater for every situation. Therefore, there are a number of optional extras available:
- Pipework - We have various pipe kits available. There are two small refrigerant copper pipes connecting the indoor to the outdoor unit, and an electrical communications cable. You will need to know the distance between the indoor and outdoor units to select the correct kit length. Your F-GAS registered engineer should install this pipework and make all final connections.
- Brackets - The brackets are available if you want to mount the outdoor unit on a wall.
- Check box - The check box is simply there to ensure that you are aware that these systems need to be installed by an F-Gas certified engineer.
- Wifi Dongle - Control your unit via the smart app - FRIWF-USB-02 (Optional)
