Periodic Maintenance
4.2 Air Inlet Filter
Element
A dirty filter element can cause high operating temperatures and affect
ventilator performance. Examine the filter element (Figure 4-1) and if
necessary see Chapter 5 for component removal/installation instructions.
•
Inspect the foam lining of the filter cover, and use a vacuum to
thoroughly clean any visible lint or dust. Replace the cover if hinge
damage prevents the cover from closing properly.
•
Remove the old air inlet filter element from the filter housing and
discard.
•
With the air filter element removed, inspect the filter housing nylon
mesh filter for lint, dust, or damage. Use a vacuum (
not
a compressed
air source) to remove lint or dust.
•
Install a new air inlet filter element (white side facing out) into the
filter housing, then reinstall the air inlet filter cover.
•
The air inlet filter element is a single-use part. Do not attempt to clean
or reuse. Use only Respironics-approved parts.
