Using the HARRIS 25GX Oxygen Regulator is easy. First, connect it to your oxygen source using the CGA 540 inlet connection. Then, adjust the pressure using the ergonomic ABS plastic knob until you reach the desired delivery pressure within the 0 - 145 PSIG range. You can check the pressure on the easy - to - read 2.5' steel dual - scale gauges. When it comes to safety, make sure the regulator is UL listed and installed properly. Keep the area around the regulator clean to prevent contaminants from entering. For maintenance, inspect the brass body and chrome - plated zinc bonnet regularly for any signs of wear. The neoprene diaphragm and PTFE Teflon® seat are designed for long - term use, but if you notice any issues with pressure control, it might be time to check them. Also, consider using the recommended steel gauge guards for added protection. With a 7 - year warranty, you can use this regulator with confidence for your medium - to - heavy - duty oxygen needs.
