Just got this compressor, now what?

[Jimmer]

Can anyone think of anything else that we might need?

Yes, you need to send it to my house when it's done

I can re-wire the unit to a 4 wire but I do not understand why it needs it if there is no GFI on that circuit but I trust you know more than I do about that so we will do it. I think there may be a transformer on the large switch in the control box.

If the solenoids (and or the contactor) uses 115 vac, and you have only two hots and a ground, and no control transformer, you are using the ground as the neutral for the 115, or you have a neutral and no ground.

The motor only needs the two "hots" to run.

With a 220-115 control transformer you no longer need to use the ground as the neutral.

This also eliminates the possibility that you could interrupt one of the two hot leads (which will stop the motor) and still have "live" 115 in the control box. This can be a failed circuit breaker, bad connection etc.

Fortunatly Brian is the smart one in this group and he understands what your saying, hehe I am just the dumb mussle, you know good for moving heavy stuff around busting rusted bolts loose...."Mongo like beans":smash:

I just noticed you guys are in SD. Not too far away.

Let me know if you need some help unscrambling the controls.

Cool thaks for the offer.

You know, Every one is giving you advice, maybe I should just bug out and leave you to your own divices. I'm tired of the interjection from people that have no clue about these units. Let them figure it out for you. I know how these units were built, but popular opinion seems to be the rule of the day. Good Luck and I hope you figure it out.

LOL ... welcome to Scubaboard Craig. It's always been like this and always will.

OK, We're pumping air. So how can we be sure the back pressure valve is working? How do we adjust it? Do we need to put a gauge in the system before the valve?

To set a Priority valve you need a gauge ahead of the valve.

The pressure should rise without flow through the valve until the set pressure is reached, then flow will commence.

Priority Valves have a spring with adjustable preload, depending on the exact valve there will be some means of increasing or decreasing the preload on this spring.

The priority valve is attached to the Triplex filter. Where can we put the gauge? What should the pressure be set to.
