Section 4. Maintenance
4.1. Replacing the Filter
To protect the pump from damage due to
foreign particles and moisture, replace
the filter as it becomes dirty. With
moderate use (15 to 30 minutes a day), it
is recommended that the filter be
replaced once per month. In dirty
environments or with heavy use, replace
the filter more frequently. Always
replace the filter when it is visibly dirty or
wet. To replace the filter, follow the
steps below.
1.
Remove the black rubber probe tip.
2.
Pick out the filter with a pin or
tweezers. A fine screen will remain in
the tip of the probe nozzle (behind
where the filter sits).
3.
Insert the new filter in the probe tip.
Make sure that the filter is firmly
seated against the screen.
4.
Replace the rubber probe tip.
4.2. Replacing the Airflow Indicator
1.
Remove the clear plastic section of the
probe tip by gently pulling and
twisting.
2.
Turn the probe tip upside-down and
tap on it to remove the old airflow
indicator ball.
