Help! I have a hydraulic place diverter on a 12jg pump. Just put a new Bennet hydraulic pump on it. And it will only go up not back down! I think I need to bleed it. Maybe not?

Need a little advice!

It's 2 button up and down. I might have to change the wiring to a different switch now that I took it out today and played with it but what are some other switch setups are there that are different. The old pump had 4 solenoids this one has 2
