INTRODUCTION
RULES FOR SAFE INSTALLATION AND OPERATION!
Carefully read and follow aU safety instructions in this
manual or on pump.
A This is the safety alert symbol. When you see this
symbol on your pump or in this manual, look for one of the
following signal words and be alert to the potential for per
sonal injury!
A DANGER
serious personal injury, death or major property damage if
ignored.
AWARNING ItyARNTNG warns about hazards that can
cause serious personal injury, death or major property dam
age if ignored.
[A^AUTIO^ CAUTION warns about hazards Chat will or
can cause minor personal injury or property damage if ig
nored.
The word NOTICE indicates special instructions which are
important but not related to hazards
l.To avoid risk of serious bodily injury and property dam
age, read safety instructions carefully before installing
pump.
I DANGER wam,s about Itazards that will cause
2. Follow local and/or national plumbing and electrical
codes when installing pump,
3. Keep the well covered while installing pump to prevent
leaves and other debris from falling into well, contami
nating well and possibly damaging pump.
4. Protect pump and piping system from freezing. Allowing
pump or water system to freeze could severely damage
pump and voids warranty.
AWARNING ¡Hazardous Voltage. Can shock, burn.
cause death, or start fires.
5. Disconnect electrical power source before installing or
working on pump,
6. Ground pump with a ground wire run from grounding lug
on motor to a grounded lead in the service panel.
7. Line voltage and frequency of electrical power supply
must agree with motor nameplate.
8. Lise of fuses or wire smaller than size recommended in
owner's manual can cause overheating, pos.siblc fires, and
will void warranty.
9. Ihtmp water only with this pump,
10. Do not run pump dry. To do so will damage seals and can
cause leaking and property damage.

BASIC TOOLS AND MATERIALS NEEDED
Pipe Wrenches
Hacksaw
Adjustable Wrench
Screwdriver
Check Valve
Teflon Tape
Knife
NOTICE: Depth to water must not be more than 20’.
1. Long runs and many fittings increase friction and reduce
flow. Locate pump as close to water source as possible:
use as few elbows and fittings as possible.
2. Be sure water is clear of sand. Sand 'will plug the pump
and void the warranty.
3. Protect pump and all piping Irom freezing. Freezing will
split pipe, damage purhp and void the warranty. Check
locally for frost protection requirements (usually pipe
must be 12” below frost line and pump must be insu
lated).
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 Teflon tape or Plasto-Joint
Stik' to seal pipe joints.
7. Unions installed near pump and water source will aid in
servicing. Leave room to use wrenches.
A WARNING
8.
Pump body may explode if used as a
booster pump. DO NOT use in a booster application.

your well type.

Figure I - Cased/Dug Well Installation
DRIVEN POINT INSTALLATION
1.
Connect the suction pipe to the drive point as illustrated in
____
2590 0996
Figure 2. Keep horizontal pipe run as short as possible. Use
Teflon tape on male pipe threads. Multiple well points may
be necessary to provide sufficient water to pump.
2.
Install a check valve in piping as shown in Figure 2. Flow
arrow on check valve must point toward pump.
Suction Pipe
to Pump
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 suc
tion pipe and lower pipe into well. Add sections of pipe
as needed, using Teflon 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 low
est level to which water will drop while pump is operat
ing (pumping water level). Your well driller can furnish
this information.
3. To prevent sand and sediment from entering the pumjv
ing 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 weU
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.

HORIZONTAL PIPING FROM WELL TO
PUMP
1. Never install a suction pipe that is smaller than the suc
tion tapping of the pump.
INSTALLATION (Continued)
2, To aid priming on driven 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 tapping. 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.
• Up to 100’ run: Same size as pump discharge tapping.
• 100’ to 300’ run: Increase one pipe size.
• 300' to 600’ run: Increase two pipe sizes.
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

Do not use in a pressure tank or booster pump
application.
Pump/Piping Installation
PUMP INSTALLATION
NOTICE: Use Teflon tape supplied with the pump for mak
ing all threaded connections to the pump itself. Do not use
pipe joint compounds on the pump: they can react with
the plastic in the pump components.
1. Bolt pump to solid, level foundation.
2. Support all piping cormected to the pump.
3. Wrap 1-1/2 to two layers of Teflon 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 over
tighten.
NOTICE: Install pump as close to water source as possible.
Long piping runs and many fittings create friction and re
duce flow.
Use schedule 80 or iron pipe. See “Well Pipe InstaUation” for
more information.
