GENERAL SAFETY
Do not touch an operating motor. Modern
motors may operate at high temperatures. To avoid
burns when servicing pump, allow it to cool for 20 min-
utes after shut-down before handling.
Do not allow pump or any system component to freeze.
To do so will void warranty.
Pump water only with this pump.
Periodically inspect pump and system components.
Wear safety glasses at all times when working on
pumps.
Keep work area clean, uncluttered and properly lighted; store
properly all unused tools and equipment.
Keep visitors at a safe distance from the work areas.
Pump body may explode if used as a
booster pump unless relief valve capable of passing full
pump fl ow at 5 Bars (75 psi) is installed.
SHALLOW WELL JET PUMP
INSTALLATIONS:
• Have a vertical depth between the pump and the
water being pumped of 25' or less.
• Have one pipe from the well to the pump case.
• Can be installed in a bored or drilled well, or in a
driven well.
REPLACING AN OLD PUMP
Hazardous voltage. Disconnect power to
pump before working on the pump or motor.
1. Drain and remove the old pump. Check the old pipe
for scale, lime, rust, etc., and replace it if necessary.
2. Install the pump in the system. 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 cannot lift water from the water source.
3. Adjust the pump mounting height so that the plumb-
ing connections do not put a strain on the pump
body. Support the pipe so that the pump body does
not take the weight of piping or fi ttings.

new shallow well jet pump. Please go to Pages 5 and 6
for discharge pipe and tank connections.
WELL POINT (DRIVEN POINT)
INSTALLATION (FIGURE 1)
1. Drive the well, using drive couplings and a drive cap.
WARNING
Hazardous pressure!
Install pressure relief
valve in discharge pipe.
Release all pressure on
system before working on
any component.
Drive fi ttings are threaded all the way through and
allow the pipe ends to butt against each other so that
the driving force of the maul is carried by the pipe and
not by the threads. The ordinary fi ttings found in hard-
ware stores are not threaded all the way through the
fi tting and can collapse under impact. Drive fi ttings are
also smoother than standard plumbing fi ttings, making
ground penetration easier.
2. Mount the pump as close to the well as possible
3. Use the fewest possible fi ttings (especially elbows)
when connecting the pipe from the well point to the
pump suction port. The suction pipe should be at least
as large as the suction port on the pump (include
a check valve as close to the well as possible - see
Figure 1). Support the pipe so that there are no dips
or sags in the pipe, so it doesn'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
tefl on tape. Joints must be air- and water-tight. If the
suction pipe can suck air; the pump cannot pull
water from the well. If one well point does not sup-
ply enough water, consider con-necting two or three
well points to one suction pipe.
You have just completed the suction piping for your
new shallow well jet pump. Please go to Pages 5
and 6 for discharge pipe and tank connections.
