Connecting Discharge Piping - aermotor FH50 Installation And Operation Manual

Discharge Pipe and Pressure Tank Connections
PRE-CHARGE TANK
CONNECTION (FIGURE 4)
Step 1. Install two tees in the pump discharge port (see
Figure 4). The pipe size must be at least as large
as the discharge port.
Step 2. Run a pipe or reinforced hose from one arm of
the first tee to the port on the pre-charged tank.
Step 3. Connect the other end of the discharge tee to
your plumbing system.
Step 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 pres-
sure 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.
Congratulations! You have just completed the
tank connection for your jet pump.

CONNECTION (FIGURE 5)
Step 1. Install one tee in the pump discharge port (see
Figure 5).
Step 2. Run a pipe from the pump discharge port to the
inlet port of your tank. The pipe size must be at
least as large as the discharge port.
Step 3. Remove the 1/8" NPT pipe plug from the pump Air
Volume Control (AVC) port (see Figure 5). Run tub-
ing from the pump's AVC port (see Figure 5) to the
port on the AVC mounted on the tank. See instruc-
tions provided with tank and AVC for details. AVC
port location will vary, depending on your pump
model (see exploded views, Page 9).

Sealing Pipe Joints
Use only Teflon tape or Teflon based joint com-
pounds 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.
