ANNUAL MAINTENANCE
The expected life of the coalescing filter element is approximately 12 months. Failure
to replace the filter element on schedule results in a void AirSep Product Warranty.
AirSep selects concentrator filters based on their ability to perform
in severe conditions. Use of other than Original Equipment
Manufacturer filters/elements can cause damage not covered
under the AirSep Product Warranty.
Failure to maintain the air intake and compressor intake filters can
allow foreign particles in the air to enter the concentrator and cause
damage not covered under the AirSep Product Warranty.
7.3.1. COALESCING FILTER ELEMENT REPLACEMENT
The coalescing filter is located inside the PSA concentrator module (See Figure
4.4). It removes any foreign particles present in the oxygen supply.
Order the element to be replaced through the AirSep Commercial
Service Department. Specify Part Number FI018-1, cleaned for
oxygen service. Contact AirSep at 1-800-320-0303 or (716) 691-
0202 outside of the USA/Canada.
1. Wash your hands thoroughly, and make sure they are oil-free before
you begin this procedure.
Oxygen can cause spontaneous combustion, and as such, is a
fire hazard. Make sure that no flammable materials are located in
the oxygen concentrator area designated “Oxygen in Use — No
Smoking.”
2. Close the primary oxygen ball valve. See Figure 5.1 for location of this
valve.
3. Observe that the AUTO/MANUAL switch is in the AUTO position, and
wait until the blue light shuts off.
4. Set the ON/OFF switch of the PSA module to the OFF position.
5. Close the oxygen isolation ball valve. See Figure 5.1 for location of this
valve.
6. Unplug the PSA module power cord from the electrical outlet.
