INTRODUCTION
Please take a few minutes to read our instructions before you
install and use your pump. This will help you obtain the full
benefits from this pump. It will also help you avoid any need-
less service costs that result from causes we cannot control
and cannot cover in our warranty.
RULES FOR SAFE INSTALLATION AND OPERATION!
Carefully read and follow all safety instructions in this
manual or on pump.
_k 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!
_ DANGER warns about hazards that will cause
serious personal injury, death or major property damage if
ignored.
[&WARNING_wPdRNI_IG warns about hazards that can
cause serious personal injury, death or major property dam-
age if ignored.
[A CAUTION ]CAUTION warns about hazards that will or can
cause minor personal injury or property damage if ignored.
The word NOTICE indicates special instructions which are
important but not related to hazards.
1. To avoid risk of serious bodily injury and property dam-
age, read safety instructions carefully before installing
pump.
2. Follow local and/or national plumbing and electrical
codes when installing pump.
3. Keep the well covered while instalfing 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.
]_kWARNING]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.Use of fuses or wire smaller than size recommended in
owner's manual can cause overheating, possible fires, and
v_tll void warranty.
9. Pump water only with this pump.
10. Do not run pump dry. To do so will damage seals and can
cause leaking and property damage.
PREPARATION INSTALLATION (Continued)
BASIC TOOLS AND MATERIALS NEEDED
Pipe Wrenches Screwdriver
Hacksaw Check Valve
Adjustable Wrench 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 from freezing. Freezing will
split pipe, damage pump and void the warranty. Check le-
eally 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 Teflon tape or Plasto-Joint
Stik Ito seal pipe joints.
7. Unions installed near pump and water source will aid in
servicing. Leave room to use wrenches.
8. [AWARNINGIPump body may explode ffused as a
booster pump. DO NOT use in a booster application_

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 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 pttmp v¢tlllose prime and
failto 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 pump-
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 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.

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
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.

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 increagmg 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

sprinkler systems. A suggested mtdtiple discharge to service
is shown in Figure 3.
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 connected 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 Installation" for
more information.
