MN179-1 _ 02/14 AirSep Corp. - FreeStyle 5 Service Manual Rev B
4.0 Equipment Provider Maintenance
4.1 No Scheduled Maintenance
FreeStyle model units are maintenance-free due to their technologically advanced
design. AirSep does not require preventative maintenance or service on these
concentrators as long as the concentrator remains within specifications. To ensure
that the unit’s output of oxygen is within specification, you must establish and
implement a protocol to check oxygen concentration upon delivery to a patient and
at periodic intervals (Refer to Section 2.4 of this manual).
4.1.1 Air Intake / Gross Particle Filter
The external air intake gross particle filter is located in the air
intake/filter cover. You can easily remove it by hand. Instruct the
patient to clean this filter weekly. (Refer to Section 3.2.1, “Cleaning the
Air Intake / Gross Particle Filter,” of this manual.)
The filter may require more frequent cleaning if the FreeStyle 5 unit operates in
a harsh environment — a house heated by wood, kerosene, or oil, or one with
excessive cooking or cigarette smoke.
4.1.2 Product Filter Replacement
The product filter must be replaced after every 10,000 hours of use.
Product Filter/Volume Tank Replacement
1. Turn unit off and disconnect the power cord.
2. Remove the back housing, and locate the product filter/volume tank.

3. Disconnect tubing from the inlet of the product filter/volume tank.
4. Unscrew the product filter/volume tank from the product manifold.
5. Place the o-ring into the o-ring groove located on top of the volume tank.
