Thx Chilling.

Yes , its something to work on.
Its a twin fan unit, both condenser fans are three phase.
Im installing this unit , was supplied with wires all ripped out from electrical box.
Im trying to figure out where all the wires go to, ie: through the relay/overload device ( is that what its called)
I think its a 5 hp unit, semi hemetique and oldish.........ran on R22
Ive done all the electrics, going to site tomorrow, want to wire up the compressor now so I can start the bleeder!!
