INSTALLATION PROCEDURE
STEP 1
RECOMMENDED INSTALLATION PROCEDURE
1. EXCAVATION
Dig hole from the side for accurate sizing. This reduces the
bridging distance between the tank and undisturbed soil and
provides good support for inlet and outlet pipes. The bottom of
the hole should be undisturbed and level. If leveling is necessary
due to over excavation, use sand for fill.
NOTE: Never place tank directly on rock. Place at least six
inches of sand or gravel bedding between the tank and rock
surface.
2. TANK PLACEMENT:
Use the backhoe to set the tank. Lifting lugs are furnished to lift
the tank.
CAUTION: A small amount of soil or sand should be used
around the bottom of the tank to hold it in place. Sand is best. If
excavated soil is used, tamp it underneath the tank to provide a
good base.
3. FILL TANK WITH WATER:
Place hose in six inch riser. Begin filling tank with water.

4. GFI CONTROLS AND AIR PUMP
Install duplex or quadruple GFI or GFI protected receptacles at
the selected location of the air pump. Mount control panel and
install fittings, tubing and piping to tank location.
CAUTION: Do not plug anything but the air pump into the control
panel.
5. INLET/OUTLET AND AIR CONNECTIONS
Properly make solvent cemented inlet, outlet and air
connections.
6. FILLING THE TANK
Finish filling tank with water until it drains out of outlet. Begin
backfilling with natural soil or a good back fill material.
7. AIR DISTRIBUTION
Turn the air pump on and check all air connections and piping
for air tightness. Observe air/water mixture through 4" riser.
NOTE: If the electrical GFI receptacle has not been installed
prior to checking the air distribution system during installation,
use an extension cord to run the air pump. Remove it after
inspection is completed.
