Wiring a 230V 3 phase heat pump

yes, this is quite important when it comes time to turn the motor. in 3 phase, motor rotation direction is critical importance. however, it is a simple matter of trial and error if only a fan is involved...not sure of consequences if freon pump is turned backwards...may want to remove pump wiring temporarily...so try "bumping" the fan only...your method for this "fan only" is yours to figure out. try to set to "fan only" somehow then apply power. if fan turns backwards, the take any 2 black wires and reverse connections. fan should now turn in proper direction.
