Before You Install Your Pump
NOTICE
1. The pump’s water suction inlet must not be move
than 20’ above the water level.
2. Long runs and many ttings increase friction
and reduce water ow to the pump. Locate pump
as close to water source as possible; use as few
elbows and ttings as possible. Be sure suction
line is straight and angles up toward pump to
avoid air lock.
3. 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.
4. Protect pump and all piping from freezing.
Freezing will split pipe, damage pump and void
warranty. Check locally for frost protection require
ments. Pipe cannot be installed above frost line
and pump must be insulated.
5. Foot or check valves must be installed in suction
pipe to optimize pump suction.
6. Be sure all pipes and valves are clean and in
good shape.
7. No air pockets in suction pipe.
8. No leaks in suction pipe. Use Teon tape or
other approved sealants to seal pipe joints.
9. Unions installed near pump and well will aid in
servicing. Leave room to use wrenches.
Risk of explosion.
Do not ground to a gas supply line.
Pump body may explode if used as a booster pump
or other than a lawn sprinkling application.
Risk of burns.
Motor normally operates at high temperature and will
be too hot to touch. It is protected from heat dam-
age during operation by an automatic internal cuto
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
water source.

INSTALLATION
!
Cased Well/Dug Well Installation- Figure 1
1. Inspect foot or in line check valve to be sure it
works freely. Inspect strainer to be sure it is clean
and secure.
2. If using foot valve, connect foot valve and
strainer to rst length of suction pipe and lower
pipe into well. Add sections of pipe as needed,
using Teon tape on male threads. Note: use
1-1/2” pipe for suction pipe. Be sure all suction
pipe is leak proof 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 (pumping water level).
Your well driller can furnish this information.
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.
4. When proper depth is reached, install sanitary well
seal over pipe and in well casing. Tighten bolts to
seal casing.
5. When using foot valve, a priming tee and plug are
recommended. (Fig. 1).

Keep horizontal pipe run as short as possible.
Use Teon tape on male pipe threads. Multiple
well points may be necessary to provide
sucient water to pump.
2. Install check valve in horizontal pipe. Flow
arrow on check valve must point toward pump.

Lawn Sprinkling Application
This pump is designed for lawn sprinkling. When prop-
erly installed it will deliver adequate water and pressure
from any well source.
Pump/Piping Installation
If turning pump on and o by pressure, a pressure
switch and tank are required. For proper follow tank and
switch instructions or contact a qualied plumber/elec-
trican.
Use rigid pipe. Do not use hose or plastic tubing. See
“Well Pipe Installation” for more information.
NOTICE
Use only PTFE pipe thread sealant tape to joint com-
pounds 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 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 pump.
3. Wrap 1-1/2 to 2 layers of Teon 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.
5. Replace prime plug with pressure gauge. This will aid
in sizing zones, troubleshooting, and following pump
performance chart.
NOTICE
For long horizontal pipe runs, install a priming tee
between check valve and well head (Fig. 1).
Pipe from Well to Pump
1. Pump performance will be decreased if the pipe
diameter is less than the inlet size of the pump. In
proper installation, the pipe size equals the inlet size.
2. To aid priming on well point installations, install line
check valve. Be sure check valve ow arrow points
toward pump.
Pipe from Pump to Sprinkler Heads
Discharge pipe size should be increased to reduce
pressure 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.

Wiring Connections
Risk of electric shock. Electricity
can shock, burn or kill.
1. To avoid dangerous or fatal electrical shock, turn OFF
power to motor before working on electrical
connections.
2. Ground motor before connecting to electrical power
supply. Failure to ground motor can cause severe or
fatal electrical shock hazard.
3. Supply voltage must be within +/- 10% of nameplate
voltage. Incorrect voltage can cause re or damage
motor and voids warranty. If in doubt consult a
licensed electrician.
4. Use wire size specied in Wiring Chart (below). If
possible, connect pump to a separate branch circuit
with no other appliances on it.
5. Do not ground to a gas supply line.
6. Wire motor according to diagram on motor nameplate.
If nameplate diagram diers from diagrams above,
follow nameplate diagram.
7. If this procedure or the wiring diagrams are
confusing, consult a licensed electrician.

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 rst step).
Risk of burns. NEVER run pump dry.
Running pump without water may cause pump to over-
heat, damaging seal and possibly causing burns to per-
sons 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. 4).
Step 4. Replace priming plug, using Teon tape on
thread; tighten plug.
NOTICE If priming tee and plug have been
provided for long horizontal run, be sure to
ll suction pipe through this tee and replace
plug. (Use Teon 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
horizontal run (10’ (3 m)) of horizontal
suction pipe = 1’ ((30.5 m) 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, rell
and try again.
Risk of explosion and scalding.
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. 5). Replace priming plug with pres-
sure gauge to monitor pressure so that is it not allowed to
exceed maximum pumping pressures according to perfor-
mance 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 begins
to feel warm to touch, shut o pump and allow system to
cool. Release all pressure in system and rell pump and
piping with cold water.
