Q: Hi Steve,

I just had Atlas Copco come and change out a failed drain valve. They installed the Atlas Copco EWD - 50. I think it is working but here is my question. The light is always green......I pushed the test button a few times to test it does nothing. What is the test button to do? How does the test button work?


by Gerald from California on July 11, 2016

A: Gerald

I'm looking through the manual and it's not addressing the test button so I need to refer you to Atlas. Here's the national number. If you can supply our order number we can get our local sales rep with Atlas to contact your directly.

The problem might be in your Air... more

The Factory Warranty on all of the air compressors we sell is taken care of by the manufacturer. That being said, the folks at Atlas Copco should be taking care of any defects in material or workmanship that arise in the first year.

If you would please send the details of your situation to us at '' we will be happy to work with our Atlas Copco representative to get it resolved.
