CHECKING AND REPLACING THE AIR INLET FILTER
The air inlet filter is used to filter ambient air entering through the back of the compressor.
The compressor air inlet filter needs to be changed every three to six months, or as needed.
NOTE:
The compressor is shipped with an air inlet filter already installed.
Place the patient on an alternate means of ventilation.
If operating in Stationary or Extended Range Configuration, power off the ventilator.
Power off the compressor.
To inspect the filter, locate the filter on the back of the unit.
Remove the used filter and inspect the filter.
Replace the filter if it is blocked by dirt or dust or is otherwise
contaminated. If replacing the filter, obtain an approved replacement
filter. For more information about purchasing replacement filters, refer to
"Accessories and Replacement Parts" on page 147.
If the filter is clean, return it to the back of the compressor.
NOTES:
• Reusing contaminated filters is not recommended.
• Dispose of used filters in accordance with your facility's guidelines or local regulations.
• The filter might need to be changed more frequently in particulate-filled environments.
WARNING:
• Do not power on or use the compressor without the filters and condensation tray properly installed.
• Do not insert foreign objects into any part of the ventilation system.
CAUTION:
Use only an approved filter with the compressor.
