efficient pump operation.
Use the Friction Loss
Tables to calculate total
dynamic head using different pipe
sizes. As a rule of thumb, use 1" for
up to 10 gpm, 1¼" for up to 30 gpm,
1½" for up to 45 gpm, and 2" for up
to 80 gpm. In the case of long pipe
runs it is best to increase pipe size.
Some pumps are capable of very high
discharge pressures, please select pipe
accordingly. Consult with your pipe
supplier to determine the best type of
pipe for each installation.
2.2 Pressure Tank,
Pressure Switch
and Pressure Relief Valve
Do not install tank where
it will be subjected to
spray from irrigation
systems. Exposure to such
spray could result in
corrosion of the tank,
eventually leading to an
explosion which can cause
property damage, serious
personal injury or death.
and pressure relief valve. The tank
should be located in an area where a
leak will not damage property.
The pressure switch should be
located at the tank cross tee and
never more than 4' from the tank.
Locating the switch more than
4' from the tank will cause
switch chatter.
Do not install valves, filters, or high
loss fittings between the switch and
the tank(s) as switch chatter may
result. As an example, a 1¼" spring
check valve has friction loss equal to
12' of pipe, placing the valve between
Select a dry location in
which the ambient temperature is always above 34º
F (1º C) in which to install
the tank, pressure switch,
the pressure switch and the pressure
tank is the same as moving the pressure switch 12' away from the tank. It
will create switch chatter.
On multiple tank installations the
switch should be as close to the center of the tanks as possible. Multiple
tank installations should have a manifold pipe at least 1½ times the size of
the supply pipe from the pump. This
will reduce the Friction Head in the
manifold and reduce the possibility
of switch chatter.
Pressure relief valves are required on
any system that is capable of
producing 100 psi or 230' TDH. If
blow-off may damage property,
connect a drain line to the pressure
relief valve and run it to a suitable
drain.
2.3 Adjusting Tank
Pre-Charge
Insure that the tank is empty of
water. Use a high quality pressure
gauge to check the tank pre-charge
pressure. The pressure should be 2 psi
below the pump cut-in pressure. As
an example, a 30-50 psi system would
use a tank pre-charge of 28 psi.
2.4 Discharge Pipe
Note: Most discharge heads are
threaded into the casing with lefthand threads. Hold the pump only
at the discharge head when installing
fittings. Failure to hold the discharge
head will loosen it and pump damage
will result on start-up.
If your pipe requires an adapter we
strongly recommend using stainless steel. Galvanized fittings or pipe
should never be connected directly to
a stainless steel discharge head as
galvanic corrosion may occur. Plastic
or brass pumps can use any
material for this connection. Barb
type connectors should always be
double clamped.
7
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 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
attach to the drop pipe.
2.6 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 distance between the AV11
and check valve with snifter valve
determines the amount of air introduced on each cycle. See the table for
recommended 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
dangerous 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.
2.7 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
hammer and upthrust damage:
• Built-in stainless steel valves have a
flat which is easily drilled through
using an electric drill and a ¼" or
3
⁄8" drill bit to disable the valve.
• Poppet style check valves which
are threaded in from the top of
the discharge head can be easily
removed using a ½" nut driver or
deep socket. The hex hub is visible
and accessible from the top.
• Internal Flomatic™ design plastic
poppet style valves must be
removed from inside which
requires pump disassembly.
• Built-in plastic poppet style valves
with a stem through the top may
be removed from discharge head
by pulling on the stem with pliers.

3.1 Splicing Wire to
Motor Leads
When the drop cable must be spliced
or connected to the motor lead, it is
necessary that the splice be watertight. The splice can be done with
heat shrink kits or waterproof tape.
A. Heat Shrink Splice Instructions
To use a typical heat shrink kit: strip
½" from the motor wires and drop
cable wires; it is best to stagger the
splices. Place the heat shrink tubes
on the wires. Place the crimps on the
wires and crimp the ends. Slide the
heat shrink tubes over the crimps and
heat from the center outward. The
sealant and adhesive will ooze out
the ends when the tube shrinks. The
tube, crimps, sealant, and adhesive
create a very strong, watertight seal.
B. Taped Splice Instructions
A) Strip individual conductor of
insulation only as far as
necessary to provide room for a
stake type connector. Tubular
connectors of the staked type are
preferred. If connector O.D. is
not as large as cable insulation,
build-up with rubber electrical
tape.
B) Tape individual joints with
rubber electrical tape, using two
layers; the first extending two
inches beyond each end of the
conductor insulation end, the
second layer two inches beyond
the ends of the first layer. Wrap
tightly, eliminating air spaces as
much as possible.
C) Tape over the rubber electrical
tape with #33 Scotch electrical
tape, or equivalent, using two
layers as in step "B" and making
each layer overlap the end of the
preceding layer by at least two
inches.
In the case of a cable with three
conductors encased in a single outer
sheath, tape individual conductors as
described, staggering joints.
Total thickness of tape should be no
less than the thickness of the conductor insulation.

Three phase - make the connections
between L1, L2, L3, and ground on

and then to the circuit breaker panel.
Three phase installations must be
checked for motor rotation and
phase unbalance. To reverse motor
rotation, switch (reverse) any two
leads. See the instructions for checking three phase unbalance in section
4.6. Failure to check phase unbalance
can cause premature motor failure
and nuisance overload tripping. If
using a generator, see Technical Data
for generators.
Complete the wiring by
making the connection
from the single phase pressure switch Line terminals
to the circuit breaker panel
or disconnect where used.
4.5 Three Phase Overload
Protection
Use only Class 10, quick-trip overload protection on three-phase
submersible motors. See Definite
Purpose Starters in this manual.
Call the pump manufacturer’s
Customer Service group for selection
assistance.
10
4.6 Three Phase Power Unbalance
A full three phase supply consisting of three individual transformers
or one three phase transformer is
recommended. “Open” delta or wye
connections using only two transformers can be used, but are more
likely to cause poor performance,
overload tripping or early motor
failure due to current unbalance.
Check the current in each of the three
motor leads and calculate the current
unbalance as explained below.
If the current unbalance is 2% or
less, leave the leads as connected.
If the current unbalance is more
than 2%, current readings should
be checked on each leg using each
of the three possible hook-ups. Roll
the motor leads across the starter in
the same direction to prevent motor
reversal.
To calculate percent of current
unbalance:
A. Add the three line amp values
together.
B. Divide the sum by three, yield-
ing average current.
C. Pick the amp value which is
furthest from the average current
(either high or low).
D. Determine the difference
between this amp value (furthest
from average) and the average.
E. Divide the difference by the
average.
Multiply the result by 100 to
determine percent of
unbalance.
Current unbalance should not exceed
5%. If the unbalance cannot be corrected by rolling leads, the source of
the unbalance must be located and
corrected. If, on the three possible
hookups, the leg farthest from the
average stays on the same power
lead, most of the unbalance is coming
from the power source.
Contact your local power company
to resolve the imbalance.

flow must be restricted to be within
the pumps recommended operating
range. If you use a ball valve, set it,
remove the handle, tape the handle
to the pipe, and tag the valve with a
note saying, “Do not open this valve
or pump may be damaged”. The
easiest way to “set” the flow is to fill
a 5 gallon bucket and time how long
it takes to produce 5 gallons. Calculate the flow in gpm based on this
value. As the water level drops in the
well the flow will be reduced due to
increased head and the valve will not
interfere with performance.
