You require professional tools to fit this split air conditioner, mainly a vacuum pump, and a split valve, these two alone will set you back over £300 and you will need some gas to purge the system, a pro will charge around £100 to commission the air con unit. I required the 10m kit, which does indeed have 10m copper pipes, but only a 5m drain pipe, so you'll have to go out and buy a 10m version of this if you need longer than 5m. Overall I would never have bought this item if I knew the additional cost of installing the item.
Could not review the function of the item, as I had to sell the item on before I could fit it, this is because I had such a small time frame to fit the item within the build of the house, I was unable to get someone to fit it for me. I wish people who sell these would make it clear how much work is involved in fitting them.
