The pump discharge head has a loop
for attaching a safety cable. The use of
a safety cable is recommended when
using poly pipe as the pipe stretches
when under pressure and filled with
water.
2.5 Assemble Pump End to
Motor
Remove the cable guard from the
pump (water end). Attach the water
end to the motor aligning the cou-
pling grooves to the grooves on the
motor shaft. Important: the coupling
should be completely lowered onto
the motor shaft, spin the motor shaft
to check for free rotation. Secure
the four motor nuts in an alternating
pattern at 13 ft-lbs. Reattach the cable
guard to the water end making sure
not to pinch the motor wires.
2.6 Installing Pump in Well
If using a torque arrestor, install it
per the manufacturer's installation
instructions. Consult the seller for
information on torque arrestors and
for installation instructions.
Connect the discharge pipe to the
discharge head or adapter. Barb
style connectors should be double
clamped. Install the pump into the
well using a pitless adapter or similar
device at the wellhead. Consult the
fitting manufacturer or pitless
supplier for specific installation
instructions.
Using waterproof electrical tape,
fasten the wires to the drop pipe at
10' intervals. Pump suppliers also sell
clip-on style wire connectors that at-
tach to the drop pipe.

2.7 Special Piping For
Galvanized Tank
Systems
When using a galvanized tank install
an AV11 Drain & Y fitting in the well
and a check valve with snifter valve at
the tank. This will add air to the tank
and prevent water logging the tank.
Use an AA4 Air Escape on the tank
to allow excess air to escape. The dis-
tance between the AV11 and check
valve with snifter valve determines
the amount of air introduced on each
cycle. See the table for recommend-
ed settings. See Figure 2 in Sec 1.0.
Gaseous wells should use galvanized
or glass lined steel tanks with AA4
air escapes to vent off excess air and
prevent "spurting" at the faucets.
Methane and other explosive or dan-
gerous gases require special water
treatment for safe removal. Consult a
water treatment specialist to address
these issues.
Installations with top feeding wells
should use flow sleeves on the pump.
2.8 Check Valves
Our pumps use four different styles of
check valves. We recommend check
valves as they prevent back-spinning
the pump and motor which will cause
premature bearing wear. Check
valves also prevent water hammer
and upthrust damage. Check valves
should be installed every 200' in the
vertical discharge pipe. See notes 1
& 2 on Figure 1 for other check valve
placement recommendations.
If you wish to disable a check valve for
a drain back system, you should use
other means to prevent water ham-
mer and upthrust damage:
• Built-in stainless steel valves have
a flat which is easily drilled through
using an electric drill and a ¼" or
drill bit to disable the valve.
