4.
Install the smaller diffuser and drop pipe assembly
into first aeration chamber by bending the flexible
tubing.
Lower assembly into the tank until the
diffuser bar contacts both the floor and side wall of
the tank as shown in Figure 4.
5.
Install the longer diffuser and drop pipe assembly
into second aeration chamber by bending the
flexible tubing. Lower assembly into the tank until
the diffuser bar contacts both the floor and side wall
of the tank as shown in Figure 4.
6.
Remove the air pumps and components from their
cartons. If the air pumps will be installed in the
aeration chamber risers, install concrete support
bases for the air pumps.
7.
Install each air pump in the aeration chamber
risers on the support bases (or in a clean, dry,
well-ventilated area protected from the elements
no more than 75' from the tank). Attach each
subassembly A4 to each subassembly A5 at union
as shown in Figure 4. Securely tighten union by
hand.

To wire the air pump female electrical connectors,
unscrew the three captive stainless steel screws
from the face of the female connector.

the rigid internal receptacle body. Unscrew the
compression nut on the strain relief connector.
Insert the electrical service cable through the
compression nut, compression ring and neoprene
grommet. Strip the outer insulation back 1¼" on the
underground electrical service cable and expose
the three individual leads. Use extreme care to be
sure the insulation jackets on the individual black
and white leads are not scarred or damaged while stripping the outer jacket.
9.
Strip off the insulation jackets
hole adjacent to the brass-colored screw and tighten the screw securely. Insert the white lead into the hole adjacent
to the silver-colored screw and tighten the screw securely. Insert the bare copper ground lead into the hole that is
adjacent to the green-colored screw and tighten the screw securely. Align the insert key on the receptacle body with
the keyway molded into the rubber sleeve. Press the receptacle body into the sleeve and tighten the three stainless
steel screws on the face of the connector. Press the grommet into the electrical connector and tighten the compression
nut.
10. Plug the male connector on each air pump power cord into
the appropriate female connector.
Recirculation Pump and Piping Installation
In the clarification chamber:
1.
Thread subassembly S5 into the pump discharge as shown
in Figure 7.
2.
Solvent weld the coupling on subassembly S5 to
subassembly S6. See Figure 7.
3.
Attach pump cord to pump discharge assembly (S5-S6)
using cable ties provided.
4.
Use the discharge plumbing assembly to lower the
recirculation pump into the clarification chamber until the
