Condensor air flow direction...up or down?

[TCHANNEL]

Hi everyone...quick question. I wired up my Armstong TAC-110 today with the suggested components I found on this site (fan motor, fan, relay, caps, etc), but when I fired it up, airflow throught the outside unit flowed downward through the top of the shroud, through the condensor coils, and then outside through the shroud louvers. This is totally opposite how my home unit flows. Is this right? What direction is typical for this unit? Does it matter?

That is a DC fan and just switching the wires will change the direction of the fan motor.

The fan wants to aid the natural convection, upwards.

It is supposed to go in, up, and out the top. It's been a while since I tried reversing an a.c. motor, but I seem to remember changing the wires so the motor will turn the other direction.
