Installation
Hazardous voltage and hazardous
pressure. Disconnect all power to pump and bleed
all pressure from system before working on pump,
tank, or piping.
For jet pump installation, remove AVC tube from
port in pump body or jet body and plug port (see
Figure 3). New pumps come with plug installed.
Figure 3: Plug AVC Port when installing
pre-charged tank on existing pumps. New
pumps come with plug Installed.
NOTICE: When working on submersible pumps in
wells be sure safety rope is solidly connected to
pump and to secure anchor at the well head at all
times. Do not drop the pump down the well!
Bleeder Orifices (Figure 4)
NOTICE: For submersible pump installations, there
may be bleeder orifices in the vertical discharge
pipe. They must be removed and the tees plugged
when a pre-charged tank is installed in the system.
To do this, raise the pump and discharge piping
enough to bring the bleeder orifices clear of the
well. Remove the bleeder orifices from tees and
replace with plugs (see Figure 4). Bleeder orifices
may be any of several sizes. Have a pair each of
1/2", 3/4", and 1" plugs available. Replace pump
and reconnect the discharge pipe.
Adjusting Tank Pre-charge
In areas where temperature is high for long periods
of time, tank pre-charge pressure may increase.
This may reduce tank drawdown (amount of water
available per cycle). If this occurs, adjust pre-
charge pressure according to Chart 1, page 3.
Flush all air out of piping system and water reser-
voir portion of pre-charged tank. Required on: new
installations, pumps requiring repriming, and
pumps disassembled for service. Do as follows:
Step 1. Open faucets furthest from tank and run
pump.
Step 2. Run pump until sputtering stops and steady
stream of water flows.
