Captive Air® Tanks can be connected together to increase
the supply of usable water (drawdown).
Two tanks of the
same size will double the supply and three tanks will triple
the supply. See Figures 8 and 9 for typical installations.

NOTICE: All Captive Air® Tanks except Model 390.291352
are designed to operate in the vertical position.
When using a submersible pump, the manifold and switch
assembly must be installed in the pipe line as close to the
center of the tanks as possible. See Figures 8 and 9.
The tank is shipped from the factory with a pre-charge of
air. This system DOES NOT require the use of any outside
air charging devices such as air volume controls on jet
pumps, or bleeder orifices on submersible pumps.

OPERATION
BEFORE
YOU

PUHP
Your tank is factory charged with forty (40) pounds of air
pressure. To determine pressure switch setting, see pump
owner's manual. If your pump pressure switch cut-in setting is less than forty (40) pounds, the tank air pressure
MUST be reduced to this cut-in pressure switch setting
(see table). To do this, bleed air from the valve located on
top of the tank. Check pressure frequently with an accurate tire pressure gauge until correct pressure has been
reached.
