Before You Install Your Pump
Pump clean water only with this pump.
NOTICE: This unit is not designed for applications involving salt water or brine! Use with salt water or brine will void warranty.
To avoid clogging the pump and damaging the shaft seal, do not pump water containing solids, foreign material, sand, silt, or abrasives. Always have the suction strainer installed when the pump is operating. Failure to use a strainer may cause the pump to fail and void the warranty.
Clean the strainer and flush out the pump after each use. Make sure all of the hose and pipe connections in the suction line are tight. An air leak in the suction line will prevent the pump from priming and reduce pump performance.
Tighten all of the piping joints to the pump hand tight +1-1/2 turns only. Overtightening may break the pump and will void the warranty.
Do not allow the pump or any system component to freeze. Freezing will void the warranty.
Periodically inspect the pump and the system components.
Priming The Pump
All suction connections must be airtight. Make sure the suction lift is not more than 25 feet (7.6M).
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).
Burn Hazard. NEVER run the pump dry. Running the pump without water may cause pump to overheat, damaging seal and possibly causing burns to persons handling the pump. Running pump without water can damage the impeller and may damage the seal, causing leaking or flooding, and will void the warranty. Fill the pump with water before starting it.
Follow the steps below.
1. Remove the priming plug.
2. Make sure the suction and the discharge valves and any hoses on the discharge side of the pump are open.
3. Fill the pump and suction pipe with water
4. Replace the priming plug, using pipe thread sealant tape on the thread; tighten the plug.
NOTICE: If a priming tee and plug have been provided for a long horizontal run, be sure to fill the suction pipe through this tee and replace the plug.
5. Start the pump; water should be produced in 10 minutes or less. The time will depend on the depth to water. If no water is produced within 10 minutes, stop the pump, release all the pressure, remove the priming plug, refill the pump and pipe and try again.
Pumping From Lakes, Streams, and Ponds (See Figure 1)
Surface Water Source
Figure 1
NOTICE: Check valve or foot valve required to maintain pump prime.
Locate the pump as near as possible (vertically) to the water source, to keep the suction lift (distance from the water to the pump) as low as possible. Place the pump on level support. Protect against excess moisture and flooding.
Long pipe runs and many fittings increase friction and reduce flow. Use the smallest possible number of fittings and the shortest possible run for piping.
Support the weight of the pipe.
Be sure the water is clear of debris which can clog the pump, such as sand, dirt, or scale. Be sure the foot valve and the pipe are clean and in good condition; scale or dirt in the foot valve can cause the valve to leak. Valve leakage may cause the pump to lose its prime, which can result in pump failure.

Piping
Both the suction and discharge are tapped for 1-1/4" pipe. If you are using hose or plastic pipe for the suction and discharge, install 1-1/4" MNPT x Hose Barb or 1-1/4" MNPT x 1-1/4" Slip adapter(s) in the pump port(s).
When hose is used for suction, be sure it is reinforced hose designed for this purpose.
A strainer and foot valve should be used on the end of suction pipe, or hose, to prevent loss of prime. It will also prevent foreign material from entering the pump which may damage the impeller and plug the pump. Performance ratings are for 1" pipe. Capacity will be reduced when garden type hose or smaller piping is used. Inspect the strainer frequently and clean when necessary.
NOTICE: This unit is not designed for applications involving salt water or brine! Use with salt water or brine will void warranty.
Pump water only with this pump.
Plastic Pipe
Plastic pipe may be used for any installation of this pump. No special tools are required to use this pipe. Installation can be made quickly and easily. Plastic pipe may be used for either suction or discharge hose.
Burn Hazard. NEVER run pump dry. Running pump without water may cause pump to overheat,
damaging seal and possibly causing burns to persons handling pump. Fill pump with water before starting.
Burn Hazard. 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.
Electrical
Hazardous voltage. Can shock, burn or kill. Ground pump before connecting to power supply. Disconnect power before working on pump, motor or tank.
This pump is supplied with a dual voltage 60 Hz. motor, factory set to 115 Volts. The pump should be plugged into a properly grounded GFCI outlet.
Do not cut the round grounding prong off the plug.
Extension Cords
If using an extension cord, the wire gauge (wire size) used in the extension cord must be of sufficient size to carry the current load. This chart shows the proper cord size for the extension cord length:
Distance Up to 100' 100' to 200' 200' to 300'
Cord Wire Size (AWG) 14 12 10

Draining
The pump and piping should always be protected against freezing temperatures. If there is any danger of freezing, drain the pump and piping. To drain pump, remove the drain plug at the bottom of the pump body and remove priming plug. Drain all piping.
Lubrication
It is never necessary to add oil lubrication to this centrifugal pump or its motor. The motor is of the sealed ball bearing type, grease packed for life.
Replacing Mechanical Seal
This pump is furnished with a mechanical seal. It is properly installed at the factory to prevent leakage, and requires no further attention. It cannot be adjusted and no attempt should be made to adjust it. However, it is sometimes necessary to replace this seal. If so, please follow the instructions carefully.
The Shaft Seal
The shaft seal consists primarily of two parts, a rotating member and a ceramic seat.
NOTICE: The highly polished and lapped faces of the seal are easily damaged. Read instructions and handle the seal with care.
Removal Of Old Seal
1. Remove motor from pump body.
2. After unscrewing the impeller, carefully remove the rotating part of the seal by prying up on the sealing washer, using two screwdrivers (Figure 4A).
3. Tap out the ceramic seat with a screwdriver (see Figure 4B). Clean cavity from which seal was removed and clean motor shaft.
Installation Of New Seal
1. Clean polished surface of ceramic seat with a clean cloth.
2. Wet the O-Ring in the ceramic seat with soap solution.
3. Press seat into cavity firmly and squarely with finger pressure. If seat will not locate properly in this manner, place cardboard washer over polished face of seat and use piece of 3/4" standard pipe for pressing purposes. Figure 4C.
4. Dispose of cardboard washer and again be sure that polished surface of seat is free of dirt or foreign particles, and has not been scratched or damaged by the insertion.
5. Inspect shaft to make sure that it is clean.
6. Clean face of sealing washer with clean cloth.
7. Apply soap solution to inside diameter and outer face of rubber drive ring.
8. Slide seal assembly onto shaft (sealing face first) until rubber drive ring slides over shaft shoulder.
9. Screw impeller onto shaft until impeller hub hits shaft shoulder. This will automatically locate seal in place and move the sealing washer face up against floating seal face. Figure 4D.
10. Reassemble pump in reverse order of disassembly.

Symptom
Probable Cause(s) Pump not properly primed.
Speed too low.
Failure to pump.
Total head too high. Suction lift too great.
Excessive air leak in suction line. Water level drops while pumping, uncovering suction inlet. Air pocket or leaks in suction line. Clogged impeller. Foot valve strainer too small, or clogged.
Reduced capacity and/or head (pressure).
Insufficient submergence of suction pipe. Excessive dynamic suction lift (over 20 ft.).
Total head (pressure) more than that for which pump was intended.
Excessively worn impeller.
Mechanical troubles and noise.
Suction and/or discharge piping not properly supported and anchored.
Motor runs hot and overload kicks off.
Corrective Action
Make sure pump body is full of water. See priming instructions.
Check voltage at motor terminals and at meter when pump is operating. If low, refer to wiring instructions, or check with your Power Company. Check for loose connections.
A pump designed for high head service is needed.
Locate pump closer to source of water. Make sure suction piping is large enough.
Check and repair suction line.
Check water supply. Add pipe to suction to keep it submerged.
Check suction piping.
Remove and clean.
Use larger foot valve, clean.
Add lengths of suction pipe to keep it well below the water surface.
If caused by suction pipe friction, enlarge piping and foot valve. Otherwise move pump closer to water level.
A larger pump is needed.
Order replacement parts, using repair parts list in this manual.
See that all piping is supported to relieve strain on pump assembly.
Check the voltage dial on the motor to set it to the correct input voltage.
