TANK PUMPING PROCEDURE
Only qualified service personnel should open access ports/covers. If any contact is made with
wastewater, immediately wash and disinfect all exposed areas and contact personal physician. Failure
to do so could result in severe sickness or death.
Avoid pumping down after periods of heavy rain or when the ground water is likely to be above the
bottom of the concrete tank. Emptying the tank under these conditions could cause the tank to float
up and become dislodged if it is not sufficiently anchored to prevent flotation.
1.
Open the access ports/cover(s) and insert the hose.
Note:
We recommend that you pump out both chambers of the tank, even if only one side requires it.
2.
Pump out the tank as much as possible, maneuvering the hose if possible to multiple areas of the tank.
3.
Thicker settled solids and floating scum will likely be remaining when the majority of the water is pumped out. A
back-flushing procedure may be necessary to mix and break up remaining solids so they can be effectively pumped
out of the tank.
4.
Once the unit has been pumped out, immediately refill the tank with clean water to reduce the risk of the tank
floating and to minimize the impact on treatment. Close the access ports/cover(s) making sure it is air-/watertight.
5.
Properly dispose of the solids removed in compliance with local and state regulations.
If any stricter state, local or municipal regulations apply to you, those regulations supersede the
operational directions given here.
SEASONAL/INTERMITTENT USE
The FAST
®
System will function normally even if there is no wastewater flowing during short periods of vacancy. Examples
of seasonal/intermittent use and suggested operational procedures:
•
Summer use property
(i.e., shut down all winter): Blower should be turned off at end of summer and restarted
at least a week before returning. Please contact your local service provider to restart the system and check
with local regulations.
•
Weekend property
(i.e., used at least one weekend out of three): Maintain normal operation or use FAST®’s
SFR® blower timer feature on the control panel.
Note:
Consult your service provider and local regulations for guidance on seasonal use.
