THE GASES ARE TOXIC AND VERY HAZARDOUS.
The steps for replacing the filter are as follows;
1. Close all incoming gas valves.
2. Unscrew the clear bowl from the filter housing.
3. Unscrew the filter holder. The holder is the black plastic knob in the center of the filter.
4. Pull off old filter and replace with new.
5. Screw the filter holder back into the top of the filter housing.
6. Screw the clear bowl back on the housing.
7. Open incoming gas lines
Flow to the sample cell should be a minimum of .5 scfh and a maximum of 2.0. This flow is critical to the
nitriding process. If flow is low replace the filter. If you are unable to maintain flow contact Super
