Phase 3:
Phase Three is the most important phase in meeting specific cleanliness codes. Unlike the pre-filter, the fine filter typically
use absolute rated media. Absolute filters have a very high efficiency and will ensure that fuel leaving the system is clean to
specification and has a low water content. Like previously mentioned, pre-filtering should be performed to remove any large
particulate, water, and sludge. Pre-filtering will extend the life of the fine filters.
1. Connect the Discharge Hose to the Discharge Port 2.
2. Switch the Smart Filtration Controller to “MANUAL” and turn on air supply (not included) to begin pumping.
3. If “High Suction” conditions/alarms halt the operation, it is most likely possible to continue operations at a reduced flow
rate.
4. Monitor process and change bag filters and filter elements as necessary.
5. The Bag Filter Vessel has two vacuum gauges. The upper gauge indicates the vacuum loss in the suction line, and the
bottom gauge indicates the total vacuum at the pump inlet. The difference between the two gauges is the vacuum loss
across the filter bag. Replace the filter bag when the difference between the two gauges exceeds 15” Hg. The Smart
Filtration Controller monitors the vacuum level during operation, and will halt the system and illuminate the Alarm light
when the filter bag needs to be replaced.
6. The Final Filter Vessel has two pressure gauges. The difference between the two gauges is the pressure drop across
the final filter element. Replace the final filter element when the pressure drop reached 20 PSI. The Smart Filtration
Controller monitors return line pressure during operation, and will halt the system and illuminate the alarm light when
the final filter needs to be replaced.
7. Water Alarm: If significant water accumulates in the AXI FP-90 Water Separator, operation will be halted by the Smart
Filtration Controller and the alarm light will illuminate on the Smart Filtration Controller. Using the Water Separator Drain
Valve, drain the water from the Water Separator into an appropriate container, and resume operation.
