When you say flare pipes paul - is that a case of cutting them to length and soldering the fittings on them to bolt to the compressor ?Nope - Never done one before, however consider myself rather handy. You will need a flaring tool (Less than £20 on Amazon), however It's a few hours work if you are handy..
Think it's a 3 year warranty on most of these - however that means you have to get the local company in once a year to service it for the warranty to be valid - probably cheaper to just buy another unit if it fails...
- Drill hole in wall
- Mount indoor unit on wall
- Feed pipes out of wall
- Gently bend pipes to is parallel with the wall
- Run pipes down wall
- Flare pipes at the right length to reach the Outdoor unit on the ends
- Connect pipes
- Tighten reasonably tight (not too tight!)
- Follow instructions for charging pipe (makes a difference between units as to what order it's done - read instructions VERY carefully)
- Double check all fixings again
- Open valves
- Power up
- Set Temp
- Relax in the coolness
I think in the winter, set at 15C over the winter, it was costing around 1kw per day... so about 15-20p ( I had a power monitor on it to monitor). warming is actually cheaper than cooling!!
Check the install manual for one here : https://www.manualslib.com/manual/977038/Hitachi-Rak-18peb.html
Noo... no soldering involved... Just like brake pipes on a car the end of the ppe needs to be "flared" to match the fitting...When you say flare pipes paul - is that a case of cutting them to length and soldering the fittings on them to bolt to the compressor ?
Quite interested in getting one of these myself
Cheers

How easy is it to install one of these things?
Had this one installed in the server room at work recently, a local company supplied and fitted it and the bill came to nearly 3 times the cost of the unit (using that link). We needed the warranty they provided and it wasn't something I was prepared to take on and be held accountable for it working.
Having experienced it and been amazed at how little energy it uses (it runs off a regular plug socket - the knackered system it replaced was 3 phase) I'm keen to get another one for the home office, but would want to install it myself to save money.
Have you installed aircons in the past?
ah ok never done that before but clearly you need specilist tooling to do the job ? is that expensive stuff ?Noo... no soldering involved... Just like brake pipes on a car the end of the ppe needs to be "flared" to match the fitting...
Especially important it's correct, since on the newer refrigerants the pressure in the pipe can reach up to 500psi!
Well, it wasn't my money. I had a couple of quotes that were in the same sort of ball park.You were done.

How much should I expect to pay a one man band to install that unit if I were to buy it myself?
yeah that was the whole house. I think mine is something similar normally - what capacity is yours?
