ELECTRICAL SAFETY
Capacitor voltage may be hazardous. To
discharge motor capacitor, hold insulated handle screw-
driver BY THE HANDLE and short capacitor terminals
together. Do not touch metal screwdriver blade or
capacitor terminals. If in doubt, consult a qualified
electrician.
GENERAL SAFETY
Do not touch an operating motor. Modern
motors are designed to operate at high temperatures. To
avoid burns when servicing pump, allow it to cool for 20
minutes after shut-down before handling.
Pump is designed as a lawn sprinkler only. To avoid heat
built-up, over pressure hazard and possible injury, do not
use in a domestic water system. Do not use as a booster
pump; pressurized suction may cause pump body to
explode.
Do not allow pump or any system component to freeze.
To do so will void warranty.
Pump water only with this pump.
Periodically inspect pump and system components.
Wear safety glasses at all times when working on pumps.
Keep work area clean, uncluttered and properly lighted;
store properly all unused tools and equipment.
Keep visitors at a safe distance from the work areas.
“Dead Heading” a pump means running the pump
while little or no water is released from the system.
Never run pump above recommended pressure shown
on the performance chart.
WARNING
Hazardous pressure!
Do not run pump against
closed discharge.
Release all pressure on
system before working on
any component.
WARNING
Hazardous voltage.

Installation 4
BEFORE YOU INSTALL YOUR PUMP
NOTICE: Well must not be more than 20' (6.1m) depth
to water.
Step 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 possi-
ble. Be sure suction line is straight and angles
toward pump.
Step 2. Be sure well and pipe are clear of sand, dirt and
scale. Foreign matter will plug pump and void
warranty. Use new pipe for best results.
Step 3. Protect pump and all piping from freezing.
Freezing will split pipe, damage pump and void
warranty. Check locally for frost protection
requirements (usually pipe must be 12" (30.5cm)
below frost line and pump must be insulated).
Step 4. Be sure all pipes and foot valve are clean and in
good shape.
Step 5. No air pockets in suction pipe.
Step 6. No leaks in suction pipe. Use Teflon tape or
Plasto-Joint Stik to seal pipe joints.
Step 7. Unions installed near pump and well will aid in
servicing. Leave room to use wrenches.
Pump body may explode if used as booster
pump. DO NOT use in booster application.
Motor normally operates at high tempera-
ture and will be too hot to touch. It is protected from
heat damage during operation by an automatic internal
cutoff switch. Before handling pump or motor, stop
motor and allow it to cool for 20 minutes.
WELL PIPE INSTALLATION
NOTICE: Use installation method below which matches
your well type.
CASED WELL/DUG WELL INSTALLATION
Step 1. Inspect foot valve to be sure it works freely.
Inspect strainer to be sure it is clean and secure.
Step 2. Connect foot valve and strainer to first length of
suction pipe and lower pipe into well. Add sec-
tions of pipe as needed, using Teflon tape on
male threads (use 1-1/2" pipe for suction pipe).
Be sure all suction pipe is leakproof or pump will
lose prime and fail to pump. Install foot valve 10
to 20 ft. (3 to 6 m) below lowest level to which
water will drop while pump is operating (pump-
ing water level). Your well driller can furnish this
information.
Step 3. To prevent sand and sediment from entering
pumping system, foot valve/strainer should be at
least 5 ft. (1.5 m) above bottom of well.
Step 4. When proper depth is reached, install sanitary
well seal over pipe and in well casing. Tighten
bolts to seal casing.
Step 5. When using foot valve, a priming tee and plug
are recommended. (Fig. 1).

Installation 5
DRIVEN POINT INSTALLATION
Step 1. Connect suction pipe to drive point (Fig. 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.
Step 2. Install check valve in horizontal pipe. Flow
arrow on check valve must point toward pump.
HORIZONTAL PIPING FROM WELL TO PUMP
Step 1. Pump performance will be decreased if less that
1-1/2" pipe is used as suction pipe.
Step 2. To aid priming on well point installations, install
line check valve. Be sure check valve flow arrow
points toward pump.
DISCHARGE PIPE SIZES
Discharge pipe size should be increased to reduce pres-
sure losses caused by friction on long pipe runs.
• Up to 100' (30.5 m) run: Same size as pump dis-
charge port.
• 100' - 300' (30.5 - 91.4 m) run: Increase one pipe
size.
• 300' - 600' (91.4 - 182.9 m) run: Increase two pipe
sizes.
LAWN SPRINKLING APPLICATION
This pump is designed for lawn sprinkling. Delivers plen-
ty of water at full sprinkler pressure. Pumps from pond,
cistern or well points.
Pump discharge can be divided to supply 4 or more
sprinkler systems.
Do not use in booster pump applications.
PUMP/PIPING INSTALLATION
If turning pump on and off by pressure, a pressure switch
and tank are required. For proper installation and opera-
tion instructions call Customer Service.
Use rigid pipe. Do not use hose or plastic tubing. See
“Well Pipe Installation” for more information.
NOTICE: Use only Teflon tape or Teflon based joint
compounds 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 pump compo-
nents. 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.
Step 1. Bolt pump to solid, level foundation.
Step 2. Support all piping connected to pump.
Step 3. Wrap 1-1/2 to 2 layers of Teflon tape clockwise
(as you face end of pipe) on all male threads
being attached to pump.
Step 4. Tighten joints hand tight plus 1-1/2 turns. Do not
overtighten.
Step 5. Replace prime plug with pressure gauge. This
will aid in sizing zones, troubleshooting, and fol-
lowing pump performance chart.
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 (Fig. 1). For dri-
ven point installations, install check valve. Be sure that
check valve flow arrow points toward pump.

WIRING
Ground motor before connecting to electrical
power
supply. Failure to ground motor can cause severe or
fatal electrical shock hazard.
Do not ground to a gas supply line.
To avoid dangerous or fatal electrical shock, turn
OFF power to motor before working on electrical
connections.
Supply voltage must be within ±10% of nameplate
voltage. Incorrect voltage can cause fire or dam-
age motor and voids warranty. If in doubt consult a
licensed electrician.
Use wire size specified in Wiring Chart (below). If
possible, connect pump to a separate branch cir-
cuit with no other appliances on it.
Wire motor according to diagram on motor name-
plate. If nameplate diagram differs from diagrams
above, follow nameplate diagram.
Step 1. Install, ground, wire and maintain this pump in
accordance with electrical code requirements.
Consult your local building inspector for infor-
mation about codes.
Step 2. Provide a correctly fused disconnect switch for
protection while working on motor. Consult
local or national electrical codes for switch
requirements.
Step 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.
Step 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 .
Step 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.
Step 6. Protect current carrying and grounding conduc-
tors from cuts, grease, heat, oil, and chemicals.
Step 7. Connect current carrying conductors to terminals
L1 and L2 under motor canopy. When replacing
motor, check wiring diagram on motor name-
plate against Figure 3. If the motor wiring dia-
gram does not match either diagram in Figure 3,
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 3. Do not try to run
motor as received on 115 volt current.
Step 8. Motor has automatic internal thermal overload
protection. If motor has stopped for unknown
reasons, thermal overload may restart it unex-
pectedly, which could cause injury or property
damage. Disconnect power before servicing
motor.
Step 9. If this procedure or the wiring diagrams are con-
fusing, consult a licensed electrician.

Operation 8
PRIMING THE PUMP
NOTICE: 'Priming' refers to pump expelling all air in the
system and beginning to move water from its source out
into system. It does not refer only to pouring water into
pump (although pouring water in is usually the first step).
NEVER run pump dry. Running pump with-
out water may cause pump to overheat, damaging seal
and possibly causing burns to
persons handling pump. Fill pump with water before
starting.
Step 1. Remove priming plug.
Step 2. Make sure suction and discharge valves and any
hoses on discharge side of pump are open.
Step 3. Fill pump and suction pipe with water (Fig. 6).
Step 4. Replace priming plug, using Teflon tape on
thread; tighten plug.
NOTICE: If priming tee and plug have been pro-
vided for long horizontal run, be sure to fill suc-
tion pipe through this tee and replace plug. (Use
Teflon tape on plug.)
Step 5. Start pump; water should be produced in 10
minutes or less, time depends on depth to water
(not more than 20' (6 m)) and length of horizon-
tal run (10' (3 m) of horizontal suction pipe = 1'
(30.5 cm) of vertical lift due to friction losses in
pipe). If no water is produced within 10 minutes,
stop pump, release all pressure, remove priming
plug, refill and try again.
NEVER run pump against closed discharge.
To do so can boil water inside pump, causing hazardous
pressure in unit, risk of explosion and possibly scalding
persons handling pump (Fig. 7). Replace priming plug
with pressure gauge to monitor pressure so that it is not
allowed to exceed maximum pumping pressures accord-
ing to performance chart.
To prevent explosion be sure discharge (valve, pistol grip
hose nozzle, etc.) is open whenever pump is running.
Monitor pump body and piping temperature. Motor will
warm up; this is normal. If pump body or piping begin to
feel warm to touch, shut off pump and allow system to
cool. Release all pressure in system and refill pump and
piping with cold water.
