Operating the STAP
• The STAP will not begin sampling automatically after a filter change. The unit
must be warmed up for 10 minutes and the filter initialization test (white filter
check) completed before sampling may begin.
• Once the STAP begins sampling after the filter change, compare the flow rate
with the value before the filter change. If the flow rate is significantly differ-
ent, the filters may not be fully seated, or you may have accidentally inserted
multiple filters.
