I replaced a Sanden SD508 compressor with a Sanden SD7H15.
According to Sanden's specs the SD508 can rotate both ways, clockwise as well as counter clockwise.
The SD7H15 however can only run clockwise.
Which way do I look at it to determine which way it rotates? Thank you.

It's looking at the front of the pulley-- belt is close to you and the main body of the compressor is behind it.
