TANKS INSTALLATION
SEE DIAGRAM ON PAGE 10
Packaged systems have the pump mounted directly to the tank. The pump to tank plumbing
fittings are pre-assembled in factory. You only have to connect the discharge line of your
system to your home’s plumbing distribution line. When using a separate tank from your
pump, we recommend to install a captive air tank as shown in our typical installation diagram,
that is air injected into the tank at the factory. This air, which is in addition to atmospheric
pressure, increase the ability of the tank to deliver more water between on/off cycles, thus
increasing the efficiency of your water system. Connect the pump discharge to the tank T,
using adaptors and braided hose, then, connect the other side of tank T to your home’s
plumbing distribution line.
Make sure that the precharged air pressure (before connecting the tank) is 2
PSI less than the starting pressure setted on the pressure switch of your pump.
If you adjust the air pressure after the installation, follow these steps:
- Check the starting pressure of the pump on the pressure gauge;
- Disconnect the power to the pump;
- Open nearest fawcet to the tank and relieve all pressure in tank, then close
the fawcet;
- Adjust the air pressure of the tank (by pumping or removing air at the snifter valve)
2 PSI below pressure switch “ON” setting;
- Turn power back on to pump.
Your tank is now well precharged. Run the pump through a few cycles to verify that it works
properly.
Other types of tanks may be used, as galvanized standard tanks, epoxy or glass lined tanks.
These products do not achieve the benefits of the captive air tanks.
Epoxy or glass lined tanks with float have to be precharged by the installer. Assuming tank is
plumbed to pump and all connections are checked for leaks, follow these steps:
- Run pump thru one complete cycle, until pump shuts off;
- Disconnect the power to the pump;
- Open nearest fawcet to the tank and relieve all pressure in tank, then close
the fawcet;
- Close service line gate valve;
- With a car tire pump, inject air into the snifter valve located in tank. Watch pump
pressure gauge and stop pumping air when pressure reachs 2 PSI below pressure
switch “ON” setting;
- Return power back on to pump;
- Run pump through one complete cycle;
- Open service line gate valve.
Your tank is now well precharged. Run the pump through a few cycles to verify that it works
properly.
Galvanized standard tanks require an air volume control to be used with jet pump. We do not
recommend the installation of this type of tank with your jet pump. This type of galvanized
tank is recommended with piston pumps.
