Mounting compressor upside down

[KennyLives]

I have heard that the Viair compressors use gravity-based seals. It's possible that's why you're having those issues. I would also recommend testing your pressure switch, as they come in a number of varieties and aren't very noticeably different from each other. If all else fails, you might want to see if the old Thomas compressors will work for you.

I just found this in the user manual

1. Select a FLAT, UPRIGHT AND SECURE location where the compressor can be mounted.

It looks like it needs to be mounted upright

That is very curious, I work with quite a few compressors with similar build/technology and have seen them mounted in every way possible.

The orientation should not effect the performance of the compressor.

Make sure the regulator is not put in backwards.

That's what I thought too. But now I am not very sure.

Also, check your dials. When we had this problem last year, it turned out we were at pressure, but our dial said we were at like 80. That happened again this preseason.
