SAVE THESE INSTRUCTIONS - This manual contains
important instructions that should be followed during
installation, operation, and maintenance of the product.
Save this manual for future reference.
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 personal injury!
indicates a hazard which, if not avoided, will
result in death or serious injury.
indicates a hazard which, if not avoided, could
result in death or serious injury.
indicates a hazard which, if not avoided, could
result in minor or moderate injury.
NOTICE addresses practices not related to personal injury.
Carefully read and follow all safety instructions in this
manual and on pump.
Keep safety labels in good condition.
Replace missing or damaged safety labels.
Electrical Safety
Hazardous voltage. Follow these rules to avoid
potential harm:
• Wiremotorforcorrectvoltage.See“Electrical”
section of this manual and motor nameplate.
• Groundmotorbeforeconnectingtopowersupply.
• MeetNationalElectricalCode,CanadianElectrical
Code, and local codes for all wiring.
• Followwiringinstructionsinthismanualwhen
connecting motor to power lines.
• Makeworkshopschildproof;usepadlocksand
masterswitches;removestarterkeys.
Risk of burns. Do not touch an operating
motor.Motorscanoperateathightemperatures.To
avoid burns when servicing pump, allow it to cool for
20minutes after shut-down before handling.
California Proposition 65 Warning
This product and related accessories contain
chemicals known to the State of California to cause
cancer, birth defects or other reproductive harm.
General Safety
To avoid heat built-up in pump, over pressure hazard
and possible injury, do not use in a pressure tank
(domesticwater)system.Donotuseasaboosterpump;
pressurized suction may cause pump body to explode.
Do not allow pump or piping system to freeze. Freezing
can damage pump and pipe, may lead to injury from
equipment failure and 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.

Installation 4
Before you install your pump
NOTICE:Wellmustnotbemorethan20’depthtowater.
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possible.
2. Be sure well 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 locally 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PTFEpipethreadsealanttapetoseal

(pumpingwaterlevel).Yourwelldrillercanfurnishthisinformation.
3. To prevent sand and sediment from entering the pumping 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 5
are recommended.
Dug Well Installation
Same as cased well installation.
Driven Point Installation
1. Connect the suction pipe to the drive point as illustrated in Figure6.
Keephorizontalpiperunasshortaspossible.UsePTFEpipethread

Priming The Pump
NOTICE:Theterm‘priming’referstotheprocessofpumpingalltheair
out of the system, filling the pump and suction piping with water, and
beginning to move water through the pump and out into the system. A ‘self-
priming’pumpgenerallywillrepeatthisprocesswithoutattentiononce
thepumpandsystemarefullofwater.Ifthewaterdrainsoutofthepump
(back into the well, for example), then the whole priming process must be
repeated before operating the pump again.
Tomakesurethatthepumpwill‘retainitsprime’(thatis,thatthepump
anditspipingwillstayfullofwater),BESUREtoinstallacheckvalveinthe
pump inlet port with the flow arrow pointing towards the pump. The check
valve will prevent water from siphoning out of the pump body and back
down into the well, which will keep the pump full and allow it to restart on
its own.
DO NOT remove the recirculation valve cover (there are spring-loaded
parts inside the recirculation valve – see Figure 16) when priming or
draining the pump. The drain is a hex-head pipe plug underneath the pump
body.Todrainthepump,removethehexplug(Ref.No.17,Repair Parts
diagram). Do not disturb the recirculation valve (Ref.No.19).
• Ifthepumporthesuctionpipehavebeendrainedforanyreason,
BESUREtoreprimethepumpbeforestartingit.
NOTICE:NEVERrunthepumpdry.Runningthepumpwithoutwaterinit
will damage the seals, can melt the impellers and diffusers, and voids the
warranty. To prevent damage, fill the pump with water before starting.
1. Remove priming plug (Figure 13).
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.
4. Replaceprimingplug,usingPTFE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PTFEtapetheplug.)
5. Start pump: water should be produced in 5 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).
 Ifnowaterisproducedwithin5minutes,stoppump,releaseall
pressure, remove priming plug, refill and try again.
Hazardous pressure and risk of explosion and scalding.Ifpump
is run continuously at no flow (that is, with discharge shut off or without
priming),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.
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temperature.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.

clean cardboard washer over the polished seal face and carefully press
itintoplaceusingapieceofstandard3/4”pipeasapress.
NOTICE: Be sure you do not scratch the seal face.
6. Dispose of the cardboard washer and recheck the seal face to be sure it
is free of dirt, foreign particles, scratches and grease.

Pump Reassembly
1. Bolt the bracket down to the foundation (see Figure 23).
2. Slide the motor shaft through the seal and bolt up the motor (see
Figure23).Makesurethattheslingerisontheshaftbetweenthe
bracketandthemotorflange.Makesurethatyoudon’tchiptheseal
face with the shaft shoulders and that the shaft does not take the weight
of the motor at any time.
2. CAREFULLYslidetherotatingsealhalfontotheshaft,sealfacefirst.

4. Slide a diffuser onto the shaft (open face out) until it seats on the
bracket (see Figure 24). Follow the diffuser with an impeller on a four-
stage pump or with the stainless steel spacer if a three-stage pump.
Engagethemoldedimpellerkeyintheslotintheshaft.Don’tforceit!
Be sure that the impeller eye, with metal ring, faces out (forward - see
Figure 25).
5. Repeat step 4 with the remaining impellers and diffusers.
6. Reinstall the toothed washer, the flat washer, and the impeller nut (in
thatorder–Ref.Nos.12,13,14)ontothemotorshaft(seeFigure26).
Hold the shaft and tighten the impeller nut to 10 ft.-lbs. torque.
