The noise also covers the sound of the gas hissing out of the torch tip, which I use on my electrolyzer to know if I've got a "just right" torch adjustment to prevent backfire during lighting the flame (my electrolyzer operates nearly silently). With the BN 1000E, lighting the torch is a guessing game, though I will admit I never had a backfire lighting the torch. Which was surprising, because the gas pressure was so low (due to the electronics problem), the torch must have been on the verge of backfiring at any time.

To check the main water level, you start the BN 1000E by pushing the green button (make sure that you're on at least a 30 amp breaker). You can have the power turned on to the electronics and NOT have the power turned on to the electrolyzer. The power to the electrolyzer is only turned on when you push the "start" button on the control panel. While the BN 1000E is in this "stand-by" mode, you can release any residual gas pressure by opening your torch valve; and check your liquid level.

If all the LED's are lit up, you may have too much water in the electrolyzer, if you drain some out (save it to put back in when you've used up some water) and be careful, the solution you drain out is caustic, it will burn your skin and eyes if you spill it on you (use safety equipment to protect skin, eyes and clothes). Have vinegar and fresh water available to clean up spills. By the way, we find the water (electrolyte solution) drain (in fact all the drains) to be inconvenient, as they are just plugs on the ends of pipes; this is messy and causes solution to get on your hands.

Note: If you look down the water-fill tube in the "back-arresting" tower, you'll see liquid at the bottom. If you fill till the water you are pouring in just touches the end of the water fill tube, you'll not have too much water in the main electrolyzer; you'll have too much according to the electronics, but I've found no problem with an even higher liquid level.

Note: The water in the back-fire arrester is filled SEPARATELY from the main electrolyzer. You can also use the "modifier" tank as a second backfire arrester, just by putting water in it instead of some other fluid.

After you have a proper level of liquid in all three places (back fire arrester, modifier (if used) and main electrolyzer) You shut off your torch valve, so you'd have no gas leaks and you set your control panel. The control panel will automatically choose it's maximum settings if you don't set anything and just press "start" to start the gas production. I personally can see no reason why anyone would want to set the machine to less than it's maximums, since it automatically regulates itself to the actual gas volume you're using anyway.

If you want some other setting than the electrolyzer maximums, the control panel has to be set every time you turn the machine on, the electronics have no memory. This is a bit of inconvenience because you tend to shut the machine off instead of letting it set in "stand-by" mode because the fan is so loud. Besides, it is just good practice to shut off electrolyzers when they are not in use.

Note: My electrolyzer design can be used at any volume or pressure as well, much easier than setting electronics each time.

There are two parameters to set on the control panel; the maximum desired operating pressure and gas production. If you just push "start", the computer will assume you want the maximum values of 1,000 liters per hour and 0.5 Mp.

You push "P" to tell the computer that you're wanting to set the maximum operating pressure. The computer will ignore any setting above it's maximum of 0.6 Mp (which is about 90 psi). So to set 0.5 Mp (about 75 psi) you'll push "P", then "0" and "5", then "enter". (Actual maximum at this time is 0.06 Mp)

You push "GP" to tell the computer that you're wanting to set the maximum operating Gas Production. The computer will ignore any setting above it's maximum of 1,000 L/h (liters per hour). So to set 1,000 L/h you'll push "GP" then "1", "0", "0", "0", then "enter".

Then press "start" to actually start the gas production. Watch the pressure rise, if the pressure doesn't rise quickly, within a few seconds, then shut off the machine and check all your hose connections for a leak (I had a leak when I switched to my torch from the China torch; I forgot to tighten one of my hose connections).

As the pressure is rising, you'll see the voltage and amperage readouts fluctuating as the computer keeps the gas production within the parameters you've set. I think the gas production is "inferred" from the amperage and voltage (I see no gas metering device), so it's possible that the actual gas production could be different than the readout says. When the electrolyzer operating pressure is reached, you'll note the amperage drop off quickly and the voltage to drop off more slowly. This is the electronics cutting off the power to the main transformer, using the SCR as a switch.

Light the torch as you would a normal oxy./acet. torch; except that you hold the striker very close to the torch tip or the gas won't want to light. If you have too much gas volume, it also won't want to light. If you have too little gas volume, it will backfire.
