In the event that the filter does become occluded, the primary indication for
this would be a Low Pressure Alarm indication with the message “
CHECK
PROX LINE.
” Should this happen, replace the filter.
FLIGHT MEDICAL strongly recommends that extra Prox Inline
Filters be available at all times when using the FLIGHT 50
Ventilator.
Do not wash or sterilize the Prox Inline Filter.

Maintenance
6.2.1 Preventive Maintenance
It is recommended to take the following measures to maintain the FLIGHT 50
Ventilator:
Check the Air Inlet Filter (located behind the Filter Cover) weekly.
Replace it when the majority of the filter surface area has changed
from a clean white to dirty brown color. Air Inlet Filters are not
reusable.
HOME CAREGIVERS: When the FLIGHT 50 Ventilator is used in
homecare environments, the filter may become dirty more
frequently and therefore, it must be inspected and/or changed
more often.
NEVER reverse the inlet particle filter when it is dirty.
Inspect the FLIGHT 50 Ventilator power cord on a regular basis, for
signs of a broken or frayed power cord.
Inspect the exhalation valve and flow orifice to verify that there are
no cracks or damaged surfaces.
Wipe down the surface of the ventilator housing regularly to remove
any dust that might accumulate.
If service is required, contact your provider.
6.2.2 Dual Internal Battery Maintenance
The primary internal battery should be replaced every 12 months or sooner if
the use time no longer meets the needs of the user. This will depend on a
number of factors including settings and usage patterns. The secondary
internal battery should be replaced every 24 months.
