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.

and Plug

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 abooster 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. Installfoot 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.

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

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.

OPERATION

PRIMING THE PUMP

NOTICE: 'Priming' refers to the pump expelling all air in the

system and beginning 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 dif-

fuser. To prevent damage, fall pump with water before

starting.

1. Remove priming plug (Figure 7).

Figure 7 - Remove Priming Plug

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.

Figure 9 - Run Ten Minutes Or Less

If no water is produced within 10 minutes, stop pump,

release all pressure, remove priming plug, refill and try

again.

[AWARNING_Hazardous pressure and risk of explo-

sion and scalding. If pump is run continuously at no

flow (that is, with discharge shut offor without prim-

ing), 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,

Figure 8 - Fill Pump Before Starting

4. Replace priming plug, using Teflon 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 Teflon

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).

Figure I0 - Do Not Run Pump With Discharge

Shut Off

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.

MAINTENANCE

Pump and piping need not be disconnected to repair or re-

place motor or seal (see Figure 12). If motor is replaced, re-

place the shaft seal (Key No. 6, Page 11). 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 sell-adjnsting.

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.
