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 unit operates in 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.
