FINAL INSPECTION AND STARTUP
It is the installer’s responsibility to ensure that the tank will not float due to hydraulic conditions at the site.
Your local FAST® systems distributor may provide installation inspection services. If you have questions, call
BioMicrobics at 800-753-FAST (3278) or (913) 422-0707.
BEFORE THE UNIT IS BACKFILLED:
1. Fill the tank to the normal operating level.
2. Check for leaks in all watertight seals.
3. Turn the blower on and observe the operation of the airlift. A robust splash should be present.
4. Check for excessive back pressure: Seal all access covers, place hand about 8 in [20 cm] from FAST®
vent. If you feel air flow beyond what makes a piece of paper flutter (that is, the “paper test”), then
there is excessive back pressure, and the system’s vent must be upgraded.
5. Check for proper water level over the media. The normal water line should be ~2 in [5 cm] over the
media.
6. Check for proper alarm function. Turn off the blower circuit breaker and wait for the alarm to sound. If
the alarm does not sound after 30 seconds, review the electrical installation procedures.
7. Turn the blower back on.
8. Backfill the excavation.
9. Finally, record the FAST® unit’s serial number and other requested information in this Installation
Manual, in the Service Manual, and in the Owner’s Manual.
