2. Pack the FiveStar Alarm in its original shipping container with
suitable padding. If the original container is unavailable, an
equivalent container may be substituted if necessary. In
either case, seal the instrument in a plastic bag to protect it
from moisture. Protect the FiveStar Alarm from the rigors of
handling with sufficient padding. Damage due to improper
packaging or damage in shipment is not covered by the
instrument’s warranty.
Checking the Pump and Aspirator
Inlet Filter
The Pump Module and Aspirator Assembly contains a filtering
system to protect the pump from particles and water in the
sample air. If the filter becomes clogged, the sample flow may be
blocked or an extra load placed on the pump; therefore, check
the filter regularly.
The frequency of the checks should depend on the amount of
pump usage and the concentration of particles allowed to enter
the pump. In dirty applications it is suggested that the dust filter
be replaced every 200 hours. (See Filtering System Replacement
Parts List table at right.)
Replacing the Filters
NOTE: Exercise care when replacing the external dust and
water filters to prevent dust and dirt around the filter
housing from entering the pump housing. Any dirt
sucked into the pump and drive unit may damage
pump operation.
Dust Filter
1. Remove screws from the clear filter housing on top of the
pump.
2. Remove the fibrous dust filter from the recess on the filter
housing.
3. Install the new dust filter into the recess.
4. Replace cover.
