On another note it has been pointed out to me by my airco guy that the house he was working in had been wired incorrectly.
Into the house the main feeds were the wrong way round (reverse polarity)
1. The airco units cannot be fitted like this as it can damage them so he changed it inside the box
2. more importantly the blue/black wires are correct but it means the blue wire is LIVE not NEUTRAL. You would be in for a shock if you were wiring your internal lights and thought the switch on the wall had killed the power.
One more thing you guys might want to check.....SEE PIC BELOW
This preinstall for the airco is wrong!!! The water from the condensation tray cannot run uphill, therefore this would need chopping out again. This finish on the repair wont match the wall unless the builder does it, and it might show underneath the unit....Just keep this in mind if you are looking yourself.
Hope this info helps and if you want to contact me whilst Im here ill be happy to advise.
