Hi,
I finally found a 20 gallon horizontal tank for this compressor head for $50. Between that and the fittings, it cost around $100 bux to get this thing running again. So I “broke even” so far.
Only thing is, it won’t shut off at 100 psi. I forget how to adjust the mechanical relay to get it to shut-off when I want.
Also, the original relay pedestal was mounted directly to the tank with a 1 1/2″ pipe thread opening.
But this one I connected to a reducer street elbow and then 1/2″ copper tubing going into the side of the new tank where the connection is.
So I wonder if that reduction is causing the relay to not shut-off at 100 psi. I don’t ever run my compressors over 100 psi, and usually run them at 90 psi.
Anybody have a User Manual for this DeVilbiss compression head? The Relay is Square-D.
Thanx … Chris

Hi,
I found how to set the relay here:
It’s pretty simple.
But I still want to get a User Manual if one exists. Anyone?
Thanx … Chris
