The worst mistake you can possibly make other than not wearing face and eye protection is to be in a hurry.This shit will eat your lunch.So before you go out and seriously injure yourself,listen up!First of all it takes roughly 5 minutes to fill a converted 5 gallon propane tank[no brass or copper] up to the 80% mark with the nursing tank valve approximately 1/8 a turn open.If you open it any more than that it becomes much to loud not to mention wasteful.Its probably safe to say you don't have the proper hose fittings to adapt to the nursing tank.So you will need to go about it differently.Don't do anything stupid like attach a crude fitting hose and run it into a water cooler..........If you'll notice there are 3 valves coming off the nursing tank[some only have 2].Locate the one that is most forward of the tank.This is the one that supplies the nitrogen applicator as it pulls off the bottom.......If you notice right above the valve there is a 1/4 plug.Back that out and replace with 1/4 nipple followed by a 1/4 by 1/2 bushing with a 1/2 teflon hose conection inserted in it.Finally you will need roughly 10' of 1/2" plastic hose.You will need to back the valve assembly out from the propane tank and apply new teflon.Now attach your 1/2 hose to the teflon hose connection.Be sure it is pushed all the on.No need for a clamp as there will be no pressure.Now,you are probably wondering whats going to stop the nh3 from coming out of the original hose fittings.If you'll notice each valve has a small chain attached to it.That chain is attached to a dust cap.Take the cap and screw it down securely.Now place the other end of your 1/2 hose into the [bottom] of propane tank.Crack the valve open until you see vapor coming out of propane tank.Adjust until you reach the 1/8 a turn open.This way you build no pressure and there are no leaks.Takes about 5 minutes.Once through,be sure to back your connection out and replace the plug back into the tank.Be sure to torgue your valve assembly back to the propane tank.In the interest of safety it would be worth the time to learn some of the basics concerning nh3. http://www.nh3.com/ (http://www.nh3.com/)
