Installation 4
BEFORE YOU INSTALL YOUR PUMP
NOTICE: Well must not be more than 20’ depth to water.
1. Long runs and many fittings increase friction and reduce flow. Locate
pump as close to well as possible: use as few elbows and fittings as
possible.
2. Be sure well is clear of sand. Sand will plug the pump and void the
warranty.
3. Protect pump and all piping from freezing. Freezing will split pipe,
damage pump and void the warranty. Check locally for frost protection
requirements (usually pipe must be 12” below frost line and pump must
be insulated).
4. Be sure all pipes and foot valve are clean and in good shape.
5. No air pockets in suction pipe.
6. No leaks in suction pipe. Use PTFE pipe thread sealant tape to seal pipe
joints.
7. Unions installed near pump and well will aid in servicing. Leave room
use wrenches.
8. Pump body may explode if used as a booster pump.
DO NOT use in a booster application.
WELL PIPE INSTALLATION
NOTICE: Use the installation method below which matches your well type.
CASED WELL INSTALLATION
1. Inspect foot valve to be sure it works freely. Inspect strainer to be sure it
is clean.
2. Connect foot valve and strainer to the first length of suction pipe and
lower pipe into well. Add sections of pipe as needed, using PTFE pipe
thread sealant tape on male threads. Be sure that all suction pipe is
leakproof or pump will lose prime and fail to pump. Install foot valve
10 to 20 feet below the lowest level to which water will drop while
pump is operating (pumping water level). Your well driller can furnish
this information.
3. To prevent sand and sediment from entering the pumping system, the
foot valve/strainer should be at least 5 feet above the bottom of the
well.
4. When the proper depth is reached, install a sanitary well seal over the
pipe and in the well casing. Tighten the bolts to seal the casing.
5. When using a foot valve, a priming tee and plug as shown in Figure 1
are recommended.
DUG WELL INSTALLATION
Same as cased well installation.
DRIVEN POINT INSTALLATION
1. Connect the suction pipe to the drive point as illustrated in Figure 2.
Keep horizontal pipe run as short as possible. Use PTFE pip thread
sealant tape on male pipe threads. Multiple well points may be
necessary to provide sufficient water to pump.
2. Install a check valve in horizontal pipe. Flow arrow on check valve
must point toward pump.

HORIZONTAL PIPING FROM WELL TO PUMP
1. Never install a suction pipe that is smaller than the suction port of the
pump.
2. To aid priming on well point installations, install a line check valve
as shown in Figure 2. Be sure check valve flow arrow points toward
pump.
DISCHARGE PIPE SIZES
1. If increasing discharge pipe size, install reducer in pump discharge
port. Do not increase pipe size by stages.
2. When the pump is set away from the points of water use, the discharge
pipe size should be increased to reduce pressure losses caused by
friction.

LAWN SPRINKLING APPLICATION
This pump is designed for lawn sprinkling. It is designed to deliver plenty
of water at full sprinkler pressure. It can pump from a pond, cistern or well
points.
Pump discharge can be divided to supply two (2) or more sprinkler
systems. A suggested multiple discharge to service is shown in Figure 3.
Do not use in a pressure tank or booster pump application.
PUMP INSTALLATION
NOTICE: Use only PTFE pipe thread sealant 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 the 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.
1. Bolt pump to solid, level foundation.
2. Support all piping connected to the pump.
3. Wrap 1-1/2 to two layers of PTFE pipe thread sealant tape clockwise
(as you face end of pipe) on all male threads being attached to pump.
4. Tighten joints hand tight plus 1-1/2 turns. Do not overtighten.
NOTICE: Install pump as close to well head as possible. Long piping runs
and many fittings create friction and reduce flow.
NOTICE: For long horizontal pipe runs, install a priming tee between
check valve and well head as shown in Figure 1. For driven point
installations, install a check valve as shown in Figure 2. Be sure check
valve flow arrow points toward pump.
Use schedule 80 or iron pipe. See “Well Pipe Installation” for more
information.

2. Provide a correctly fused disconnect switch for protection while work-
ing on motor. Consult local or national electrical codes for switch
requirements.
3. Disconnect power before servicing motor or pump. If the disconnect
switch is out of sight of pump, lock it open and tag it to prevent unex-
pected power application.
4. Ground the pump permanently using a wire of the same size as that
specified in wiring chart, below. Make ground connection to green
grounding terminal under motor canopy marked GRD. or .
5. Connect ground wire to a grounded lead in the service panel or to a
metal underground water pipe or well casing at least 10 feet long. Do
not connect to plastic pipe or insulated fittings.
6. Protect current carrying and grounding conductors from cuts, grease,
heat, oil, and chemicals.
7. Connect current carrying conductors to terminals L1and L2under
motor canopy. When replacing motor, check wiring diagram on motor
nameplate against Figure 6. If the motor wiring diagram does not match
either diagram in Figure 6, follow the diagram on the motor.
IMPORTANT: 115/230 Volt single phase models are shipped from factory
with motor wired for 230 volts. If power supply is 115 volts, remove motor
canopy and reconnect motor as shown in Figure 6. Do not try to run motor
as received on 115 volt current.
8. Motor has automatic internal thermal overload protection. If motor has
stopped for unknown reasons, thermal overload may restart it unexpect-
edly, which could cause injury or property damage. Disconnect power
before servicing motor.
9. If this procedure or the wiring diagrams are confusing, consult a
licensed electrician.
PRIMING THE PUMP
NOTICE: ‘Priming’ refers to the pump expelling all air in the system and begin-
ning to move water from its source out into the system. It does not refer only to
pouring water into the pump (although pouring water in is usually the first step).
NOTICE: NEVER run pump dry. Running pump without water in it will
damage seals and can melt impeller and diffuser. To prevent damage, fill
pump with water before starting.
1. Remove priming plug (Figure 9).
2. Make sure suction and discharge valves and any hoses on discharge
side of pump are open.

3. Fill pump and suction pipe with water.
4. Replace priming plug, using PTFE pipe thread sealant tape on thread;
tighten plug.
NOTICE: If a priming tee and plug have been provided for a long
horizontal run, be sure to fill suction pipe through this tee and replace
plug. (Don’t forget to PTFE pipe thread sealant tape the plug.)
5. Start pump: water should be produced in 10 minutes or less, the
time depending on depth to water (not more than 20’) and length of
horizontal run (10’ of horizontal suction pipe = 1’ of vertical lift due to
friction losses in the pipe).
If no water is produced within 10 minutes, stop pump, release all
pressure, remove priming plug, refill and try again.
Hazardous pressure and risk of explosion and scalding. If
pump is run continuously at no flow (that is, with discharge shut off or
without priming), water may boil in pump and piping system. Under
steam pressure, pipes may rupture, blow off of fittings or blow out of
pump ports and scald anyone near.
To prevent explosion, do the following:
A. Be sure discharge (valve, pistol grip hose nozzle, etc.) is open
whenever pump is running.
B. If pump fails to produce water when attempting to prime, release
all pressure, drain pump and refill with cold water after every two
attempts.
C. When priming, monitor pump and piping temperature. If pump or
piping begin to feel warm to the touch, shut off pump and allow
system to cool off. Release all pressure in system and refill pump and
piping with cold water.
Pump and piping need not be disconnected to repair or replace motor or
seal (see Figure 13). If motor is replaced, replace the shaft seal (Key No. 5,
Page 12). Keep one on hand for future use.
Be sure to prime pump before starting.
NOTICE: Check motor label for lubrication instructions. The mechanical
shaft seal in the pump is water lubricated and self-adjusting.
NOTICE: Drain pump when disconnecting from service or when it might
freeze.
PUMP DISASSEMBLY
1. Disconnect power to motor.
NOTICE: Mark wires for correct assembly.
2. Remove capscrews holding seal plate to pump body. Motor assembly
