Default HF: Auto drain

hey Guys, I'm finally getting around to installing my HF auto drain gizmo. And despite reading the directions 5-6 times I still can't figure out exactly how to plumb it up. Perhaps it's the expertly translated Chinese to Engrish that's throwing me of ... I dunno. But it talks about getting the air to power the gizmo from the unloader. I've studied my compressor throughly and have come to conclude I don't know what the heck they're talking about in relation to my compressor.

My pressure switch has a built in unloader and this fancy little fitting that accepts the hose that unloads the air and also has some holes that I think vent the air at unload time. I had already let all the air out of the tank and removed several fittings by the time I figured out I didn't know how the unloader worked ....

somebody please tell me I'm making this more complicated than it obviously is ...

Hope this helps. On the bottom of my tank the unloader stuck out far enough that I had to add extentions onto the legs of my tank so that the unloader was not right on the floor. I think the extention made it so that the leg of the tank was about 1 1/2 inch longer.

Here is the popoff located at the bottom of the tank.

Jack,

Hope this will help. The pic is of the unloader line and switch on my IR 60 gal. As you can see the 1/4 inch sweat tee hooks to the unloader/pressure switch, the one heading downward goes to the HF Drain valve and the one going through the hole goes to the big brass fitting on the top of the tank - it's the Inlet Check Valve and has fittings for the Hi Pressure Safety Valve and the unloader line.

As you probably remember from previous threads, most of us preferred copper to the plastic that came with the drain valve. Mine blew out and I put in the trash and ran the copper.

Jack, it appears the popoff unit, cheap hunk of brass immitation pneumaticly operated valve, that actually drains the water is operated by the compressed air wasted off when the machine starts & stops.
You can determine this by inserting the popoff into the tank, and blowing into it with an air hose, when the valve gets pressure it should open and drain the tank.
If that's the case, run some tubing from the drain valve to the releif coming from the side of your pressure switch, and you have the thing plumbed.

That might be a little deceiving if Jack hasn't seen or heard one of these work before. The popoff only opens for a very short time as the unloader line is gaining or losing pressure.
