center housing near the handle and the screw in the hole in the
center housing near the muffler.

5.3 Compressor Replacement
The compressor is the “pump” within the oxygen concentrator that pushes room air into
the bottom of the sieve beds. This allows oxygen to flow out the top.
The LifeStyle compressor uses a brush-type DC motor. Over time, the brushes wear,
and the compressor does not operate properly. The expected life of the compressor is
3,000 hours.

To remove the compressor assembly for exchange, follow the steps
listed below:
1. Disconnect the LifeStyle unit from the AC or DC outlet, and remove the

2. Remove the top and bottom housing. (Refer to Section 5.2.)
3. Disconnect the suction tube.
4. Disconnect the orange 2-pin connector with the red and black wires
from the circuit board.
5. Remove the heat exchanger and clamp.
6. Remove the 3 hex nuts and split washers that hold the compressor to its
mounts.
7. Lift the compressor assembly, and stand up in the well of chassis.
8. Carefully disconnect the red compressor wires from the temperature
switch.
9. Remove compressor assembly. Inspect the vibration mounts for damage.
