The video link given above was the same one that convinced me to buy the Omega Air Charger. One thing that I have, though, that the video doesn't (maybe he just hadn't installed it yet) is a black plastic cylinder that screws into the top of the big cylinder in the rear (you have to remove a large bolt that is placed there for shipping the Air Charger). It's how you grease the piston. If I remember correctly, about every 15 minutes of run-time you're supposed the turn the green knob one click. (I went outside to take some pics for you, but it's night-time here and I need more light, so I'll take some tomorrow after the sun comes up.)
I've only filled my 66 cu.ft. carbon fiber tank once, but it went off without a hitch. Let's see if I can remember the steps I used.
You asked where the manual moisture bleed and air pressure release valves are? - it is all the same thing - as you face the compressor, find the "cut-off" gauge at the top of a squarish looking aluminum box - well, down at the bottom of it, you'll find the moisture / pressure bleed valve. It's on the left side of the Air Charger - down at the bottom. It should be closed as you fill your tank, but as you till the tank, about every 15 minutes, crack it open and allow moisture to escape - it just takes a "second".
When I filled my 66 cu ft. carbon fiber tank where's what I did.
1. I connected my carbon fiber tank to the Air Charger using the tube (it has a female foster fitting on it and connected right up to my tank) - the tube was supplied with the Air Charger.
next step:
2. I SLOWLY opened the valve on the top of the carbon fiber tank so that air will be able to flow into it. When I opened the valve, there was no leakage of air out of my tank.
next step:
3. I plugged in the power card and ascertained that the water pump (I could see water moving through the water lines) and fan were working.
next step:
4. I pressed the green button and the compressor started (it runs REAL quietly). If you press the red button, the compressor will stop, but the water pump and fan will continue to run. About every 15 minutes, I spin the green grease knob one click.
next step:
5. I set the "cut-off" value to turn the Air Charger off at around 4400 psi (not the easiest thing to see to do). Even then, I don't leave it unattended.
next step:
6. After my carbon fiber tank was filled, I turned off the Air Charger (not the water pump and fan, though) and closed the valve on my carbon fiber tank (so the air couldn't escape). Next, I opened the bleeder valve on the left side of the Air Charger so that I can disconnect the hose feeding air into my carbon fiber tank.
final step:
7. I went ahead and disconnected my tank from the Air Charger and I let the water pump and fan continue to run for 20-30 minutes, to cool it off.
That's all I can remember. I'm still using the 66 cu.ft. carbon fiber tank to air up my three PCP guns, and probably won't be needing to re-fill it for a little while.
But, when I do need to re-fill it, I don't anticipate any problems.
I hope this helps. If any of you other Air Charger owners, find any errors in my little guide, I sure hope you sound off.
All the Best,
Bobby
