  If the red light is on, first ensure the iFill oxygen cylinder is connected correctly. Then, press the start/stop switch. If the red light remains on, contact your DeVilbiss provider for service. If the red light turns on during the filling process, check that the cylinder is connected properly, remove the cylinder and reinstall it. Ensure the cylinder rotary selector is in the OFF position. Press the start/stop switch to turn off the red light and then again to restart the cylinder filling process. If the red light turns on again during filling, contact your DeVilbiss provider for service.

Why does my DeVilbiss iFill 535D Health Care Products unit shut off and alarm after 11 minutes?
- M
  Monica GarciaAug 25, 2025
  If your DeVilbiss Health Care Products unit runs for 11 minutes then shuts off and alarms, it could be due to several reasons. There might be a system air leak in components like the compressor tubing, sieve beds, accumulator tank, or bacteria filter, requiring repair or replacement. Alternatively, the OSD on the main PC board, the sieve beds, the rotary valve, or the compressor itself might be faulty, each necessitating replacement.

  If your DeVilbiss Health Care Products unit shuts off and alarms before filling a cylinder to 2,000 PSIG, it could be due to a system air leak, particularly in the compressor or four-way valve tubing connections, which would need repair or replacement. Another cause might be a faulty four-way valve with internal leakage, a faulty compressor, or a faulty intensifier, all of which would require replacement.

  If, when pressing the start button on your DeVilbiss Health Care Products unit, the standby light goes off, the filling light comes on, the fan runs, the rotary and four-way valves cycle, but the unit alarms after about 4 seconds, the issue might stem from a DC wire harness not connected to the rotary valve hall effect board. Ensure the DC wire harness is connected. Alternatively, the main PC board, rotary valve, or DC wire harness itself could be faulty, requiring replacement.

  If, when pressing the start button on your DeVilbiss Health Care Products unit, the standby light goes off, the filling light comes on, the fan runs, the rotary valve is cycling, the four-way is, and the unit alarms after approximately 4 seconds, check the DC wire harness connection to the rotary valve motor and connect it if it is disconnected.

Why does my DeVilbiss iFill 535D alarm after the compressor fails to start?

  Mike GreenSep 1, 2025
  If, when pressing the start button, the standby light goes off, the filling light comes on, the fan runs, the rotary and four-way valves cycle, but the compressor doesn't run after 10 seconds, and the unit stops and alarms after 20 seconds, it could be due to the compressor not being connected to the AC wire harness, or the capacitor wire not being connected, so ensure that AC wire harness is connected. Other potential causes include a faulty capacitor, main PC board, compressor, or AC wire harness, all requiring replacement.

  If, when pressing the start button on your DeVilbiss Health Care Products unit, the standby light goes off and the filling light comes on, but the fan does not run, the issue might be due to the fan wires not being connected to the main PC board, ensure the fan wires are connected. It could also be due to faulty fan wires or connector, which would need repair or replacement, a faulty fan, or a faulty main PC board, both requiring replacement.

  If, when pressing the start button on your DeVilbiss Health Care Products unit, the standby light stays on and nothing happens, ensure the cylinder is fully snapped onto the coupler. If the issue persists, the coupler switch might not be connected to the main PC board, requiring connection. Alternatively, the light panel start switch, main PC board, or intensifier coupler switch could be defective, necessitating replacement.

  If, when pressing the start button on your DeVilbiss Health Care Products unit, the standby light goes off and the filling light comes on instantly but nothing happens, it could be due to the DC wire harness being disconnected at the main PC board, so ensure that you reconnect the DC wire harness at main PC board.
