They run on R290 which is propane based, not a greenhouse gas.

The aircon is installed and running.
I shortened the outside copper pipes and flared the ends with a £15 brake pipe flaring kit.
Used Nylog on the flares.
As someone predicted earlier, the compression joints were four different spanner sizes from 15mm up to 20mm.
That's on two 1/4" pipe joins and two 3/8" pipe joins.
No torque wrench, just spanners.
Standard wiring would be an unsightly 13A plug and cable from the indoor unit down the inside wall to a 13A socket outlet.
Instead I extended the mains cable and bundled it with the pipework to a IP rated switch adjacent to the external unit.
All the external pipework in white 110mm x 75mm duct.

Forgot to mention.
The aircon can only be operated with the remote control.
The buttons on the supplied remote were different to the image in the User Manual.
I sent images of both to the Help Line.
They sent four different PDF manuals, none of which matched my remote - useless.
Finally admitted they were working on a new manual for the latest remote that I have.
No time frame offered.

4 months on I can report that the unit has lost it's refrigerant !
Probably a connection not torqued correctly.......... ?? !!
I decided to get it pressure tested , fixed, and refilled, but have been given the runaround by local aircon engineers.
So I will fill it with nitrogen, test for leaks, and refill with 400g of R290 myself, and hope for the best.
My question is:

Does the aircon compressor have it's own oil supply, does the Refill have oil in it, or do I have to add an unknown quantity of mineral oil myself ?

Evacuated with the pump and left it with the pump off.
Nothing lost after an hour, but pressure was halfway back to ambient the next morning.
A visual inspection of all the connections showed no signs of lost refrigerant - would there be any signs ?
Awaiting the arrival of the consumables.
