Pre-Charge Tank Connection (Figure 6)
To Household
If your system uses a Con-Aire (pre-charged) tank, it should be connected to
Water System
the pump as shown in Figure 6. The relief valve must be capable of passing
the entire pump capacity at 100 PSI pressure.
Relief
Valve Check the pre-charge of air in the tank with an ordinary tire gauge. the pre-
charge is measured when there is no water pressure in the tank. Disconnect
power to the pump and drain the tank before checking the pre-charge.
Your pump has a 30/50 PSI switch, so the tank pre-charge pressure should

Well
be 28 PSI (that is, it should be 2 PSI lower than the cut-in pressure of the
pressure switch.
No AVC is required for a pre-charged tank; the 1/8" NPT AVC port on the
pump body should be plugged.
Standard Tank Connection (Figure 7)
If your system uses a standard tank, connect it to the pump as shown in
Figure 7. The relief valve used with a standard tank must be capable of
passing the entire pump capacity at 75 PSI pressure.
Connect the Air Volume Control (AVC) tube to the 1/8" NPT AVC port
on the pump body. Run the tubing from the pump's AVC port to the AVC
mounted on the tank. See the instructions provided with tank and AVC
for details.
Use only
all threaded connections to the pump itself. Do not use pipe joint
compounds on plastic pumps: they can react with the plastic in pump
components. Make sure that all pipe joints in the suction pipe are air
tight as well as water tight. If the suction pipe can suck air, the pump
will not be able to pull water from the well.
