DP Mobile Kit Maintenance
For detailed instrument maintenance see the DP4 or DP-IR instruction manual.
Daily:
• Check the Secondary Pump Assembly filters for water/dirt and the DP filters for dirt. Remove, replace, and
empty as needed.
• Check cone height.
Once a week:
• Use a vacuum gauge to measure the Secondary Pump vacuum pressure. The vacuum pressure should not be
less than 12 in WC.
• Blow out sample lines and cones with compressed air. Disconnect the line from the Secondary Pump inlet
and blow out through the cones.
CAUTION: Do not use high pressure to the instrument, severe damage may occur.
Filters: Dirty filters restrict air flow and if not corrected could lead to possible motor overloading and early pump
failure. Check the filters periodically and clean them when necessary by removing the elements from the filter
and replace.
