10-4 Maintenance and Service
Changing an Air Filter Without a Cover
1. Turn the analyzer off by pressing and holding the Power button.
2. Remove the power cord from the back of the analyzer.
3. Remove the black mesh filter from the circular fan
vent.
4. Wash the filter with warm soapy water to remove dust,
animal hair, and any other debris.
5. Dry the filter completely.
6. Make sure the filter is not damaged. If it is, discard and
use the backup filter included with the VS2.
CAUTION: Make sure the filter is completely dry before
replacing it.
7. Place a clean filter flat in the fan vent. Tuck the sides of the filter underneath the vent’s
edges.
8. Plug the power cord into the back of the analyzer.
9. Press the Power button. The analyzer then performs a diagnostic self test, and may take a
few minutes to bring the rotor chamber to operating temperature.
Note: Refer to Section 8, “Troubleshooting” if the analyzer does not success-
fully pass the self test after cleaning the air filter. See Section 4.4 for
instructions on running samples.
