I have acquired a Fujitsu a/c, indoor model number ASY12RGF-W and outdoor model number AOY12RGSF.

However there is no wiring information with it.

What I want to know is how to wire the indoor to the outdoor, and where to wire power to, i.e. which terminals.

Both indoor and outdoor have terminals marked 1,2,3 and 4.

Can anybody help please?
