PRE-CHARGE TANK CONNECTION
1.
Install a close nipple and a tee in the pump discharge port.
The pipe size must be at least as large as the discharge port.
Run a pipe or reinforced hose from one arm of the tee to the
port on the pre-charged tank.
2.
Install a second close nipple and tee with a relief valve in the
tee.
3.
Connect the other end of the second discharge tee to your
plumbing system.
4.
Check the pre-charge of air in the tank with an ordinary tire
gauge. The pre-charge should be 2 PSI less than the cut-in
setting of the pump's pressure switch. The pre-charge is
measured when there is no water pressure in the tank. Your
new pump has a 30/50 PSI switch, so adjust the tank
pre-charge pressure to 28 PSI.
You have just completed the tank connection for your jet pump.
Please go to Pages 9 and 10 for electrical hookup.
STANDARD TANK CONNECTION
1.
Install a close nipple and a tee in the pump discharge port.
Mount a relief valve in one arm of the tee.
2.
Install a second close nipple and tee in the open arm of the
first tee. Put a priming plug in one arm of the second tee.
3.
Run a pipe from the open arm of the second tee to the inlet
port of your tank. The pipe size must be at least as large as
the pump discharge port.
4.
Remove the 1/8" NPT pipe plug from the pump Air Volume
Control (AVC) port. Run tubing from the pump's AVC port to
the port on the AVC mounted on the tank. See instructions
provided with tank and AVC for details.
You have just completed the tank connection for your jet pump.
Please go to Pages 9 and 10 for electrical hookup.
SEALING PIPE JOINTS
Use only PTFE pipe thread sealant tape or PTFE-based joint
compounds for making 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.
