1. Install the control valve, pressure gauge, and deep well plug in the
pump body. See Figure 2. Purchase Model MDWC Deep Well
Well Head
Conversion Kit to obtain these parts.
2. Mount the pump as close to the well as possible.
3. Install a flexible pipe between the well head and the pump so the con-
nection will be correct. Connect small port to small port and large port
to large port.
NOTICE: Simer jet pumps have the suction port (the larger port) below
the drive port. See Figure 3.
4. Run the drive pipe and the suction pipe from the well to the pump.
Support the pipe so that there are no dips or sags in the pipe, so it does-
n't strain the pump body, and so that it slopes slightly upward from the
well to the pump (high spots can cause air pockets which can air lock

the pump). Seal the suction pipe joints with Teflon tape
air- and water-tight. If the suction pipe can suck air, the pump cannot
pull water from the well.

PRE-CHARGE TANK CONNECTION (Figure 9)
If your system uses a pre-charged tank, it should be connected to the pump
as shown in Figure 9. The relief valve must be capable of passing the entire
pump capacity at 100 PSI pressure.
Drive Pipe
Check the pre-charge of the air in the tank with an ordinary tire gauge. The
To the Well
pre-charge is measured when there is no water pressure in the tank.
Disconnect the power to the pump and drain the tank before checking the
pre-charge. Your pump has a 20/40 PSI switch (Models 2805/6/10E) or a
30/50 PSI switch (Model 2815E), so the tank pre-charge pressure should be
18 PSI (Models 2805/6/10E) or 28 PSI (Model 2815E). That is, it should be 2
To
PSI lower than the cut-in pressure of the pressure switch.
Waste
NO AVC is required for a pre-charged tank; the 1/4" NPT AVC port on the
pump body should be plugged.

STANDARD TANK CONNECTION (Figure 10)
If your system uses a standard tank, connect it to the pump as shown in
Figure 10. 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 1/4" 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 the tank and the
AVC for details.
Use only Teflon tape 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
2
able to pull water from the well.
