Maintenance
The Alnor CF920/AIRFLOW IAQ920 requires very little maintenance to keep
it performing well.

recommend that you return your Alnor CF920/A
IRFLOW IAQ920 to TSI for
annual recalibration. Please contact one of TSI’s offices or your local
distributor to make service arrangements and to receive a Return Material

The Alnor CF920/A
IRFLOW IAQ920 can also be recalibrated in the field
using the CALIBRATION menu. These field adjustments are intended to
make minor changes in calibration to match a user's calibration standards.
The field adjustment is NOT intended as a complete calibration capability.
For complete, multiple-point calibration and certification, the instrument
must be returned to the factory.
Cases
If the instrument case or storage case needs cleaning, wipe it off with a soft
cloth and isopropyl alcohol or a mild detergent. Never immerse the Alnor
CF920/A
IRFLOW IAQ920. If the enclosure of the Alnor CF920/AIRFLOW
IAQ920 or the AC adapter becomes broken, it must be replaced immediately
to prevent access to hazardous voltage.
Storage
Remove the batteries when storing the unit for more than one month to
prevent damage due to battery leakage.
