PRESSURE TANK INSTALLATION – DEEP WELL
The Pressure Tank provides a reservoir of water under pressure and main-
tains cushion of air pressure to prevent pipe hammering and possible dam-
age to plumbing components. When water is drawn off through house fix-
tures, the pressure in the tank is lowered and the pressure switch starts the
pump.

STANDARD TANK CONNECTION
When a standard tank is used, an air volume control (AVC) adds air to the
tank when it is needed. See Figure 10 for typical standard tank installation.
To connect AVC to pump, thread a 1/4" compression fitting into tapped

hole on the front of the pump. Cut tubing to length to reach AVC; assemble
to fitting on pump and to AVC on tank. See installation instructions provid-
ed with tank and AVC for details.

PRECHARGED TANK CONNECTION
When a precharged tank is used, no AVC is necessary. See Figure 10 for
typical precharged tank installation. A precharged tank contains a factory
provided air charge.
IMPORTANT: your pump pressure switch is set for a 30-50 PSI range and
requires a tank pre-charge of 28 PSI for proper operation (see Figure 11). See
tank owner's air charge. An annual check on tank charge is recommended.
