PIPING - GENERALSupport both suction and discharge piping independently at apoint near the pump to avoid putting a strain on the pumphousing. Start all piping AT THE PUMP.Increase pipe diameter at both the suction and discharge byone (1) standard pipe size (minimum) to obtain desired per-formance and flow rate. Refer to Table I when sizing pipe foryour pumping system.NOTICE: Do not use pipe with smaller diameter on the suc-tion side of pump.

SUCTION PIPEIncrease pipe size from pump suction port as shown in Table I.Figure 1 (Page 2) depicts a recommended run of pipe and fit-tings for the suction side of a centrifugal pump. Please referto this illustration when choosing pipe and fittings for yoursuction connection.IMPORTANT: All connections must be air tight!Figure 2 (Page 2) depicts conditions that are NOT DESIR-ABLE on the suction side of a centrifugal pump and maycause problems in flow rate and priming. Please look thisillustration over carefully before choosing pipe and fittings foryour suction connection.

DISCHARGE PIPINGIncrease pipe size from pump discharge port as shown inTable I. Figure 1 (Page 2) depicts a recommended run of pipeand fittings for the discharge. Install tee with priming plug asclose to pump as possible. Figure 2 (Page 2) notes conditionsthat should be avoided. Please read over carefully beforemaking discharge connection.

PRIMING THE PUMPA pump is primed when all air in the suction line and pumpvolute has been evacuated and replaced with water.To Prime:1. Close valve in discharge line.2. Remove priming plug from tee and fill pump and suction

line with water until water is flowing back out of tee.3. Replace priming plug.4. Start pump and slowly open valve until desired water flow

is achieved.NOTICE: If water is not being pumped, turn off pump,close valve, and repeat steps 1 thru 4.

If pump volute is rotated as shown in Figure 1 (Page 2),loosen vent plug when priming to evacuate air trapped insidevolute. Tighten when volute is completely filled with water.NOTICE: Do not run the pump dry. This will damage mechan-ical seal and void warranty.

Burn hazard. Motor normally operates at hightemperature and will be too hot to touch. It is protected fromheat damage during operation by an automatic internal cutoffswitch. Before handling pump or motor, stop motor and allowit to cool for 20 minutes.

Connection diagram for dual voltage, single-phase motors.Your dual-voltage motor’s terminal board (under the motorend cover) will match one of the diagrams below. Follow thatdiagram if necessary to convert motor to 115 Volt power. Connect power supply wires to L1 and L2. For 3-phasemotors, or if motor does not match these pictures, follow theconnection diagram on the motor nameplate.

THE MOTOR IS SET FOR 230 VOLTS WHEN SHIPPED.To change the motor to use 115 volts:1. Turn off power2. Remove the back motor cover.3. Use a screwdriver or 1/2” wrench and turn the voltageselector dial counterclockwise until 115 shows in the dialopening.4. Reinstall the motor cover.

Hazardous voltage. Can shock, burn, or cause death. Disconnect power to motor before working onpump or motor. Ground motor before connecting to powersupply.

WIRINGGround motor before connecting to electricalpower 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, turnOFF power to motor before working on electrical

connections.Supply voltage must be within ±10% of nameplatevoltage. Incorrect voltage can cause fire or damage

motor and voids warranty. If in doubt consult a licensedelectrician.

Use wire size specified in Wiring Chart (Page 3). Ifpossible, 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.1. Install, ground, wire and maintain your pump in compli-

ance with the National Electrical Code (NEC) in the U.S.,or the Canadian Electrical Code (CEC), as applicable, andwith all local codes and ordinances that apply. Consultyour local building inspector for code information.

2. Provide a correctly fused disconnect switch for protectionwhile working on motor. For switch requirements, consultyour local building inspector for information about codes.

3. Disconnect power before servicing motor or pump. If thedisconnect switch is out of sight of pump, lock it open andtag it to prevent unexpected power application.

4. Ground the pump permanently using a wire of the samesize as that specified in wiring chart (Page 3). Makeground connection to green grounding terminal undermotor canopy marked GRD. or .

5. Connect ground wire to a grounded lead in the servicepanel or to a metal underground water pipe or well casingat least 10 feet long. Do not connect to plastic pipe or insu-lated fittings.

6. Protect current carrying and grounding conductors fromcuts, grease, heat, oil, and chemicals.

7. Connect current carrying conductors to terminals L1 andL2 under motor canopy. When replacing motor, checkwiring diagram on motor nameplate against Figure 3. If themotor wiring diagram does not match either diagram inFigure 3, follow the diagram on the motor.

IMPORTANT: 115/230 Volt single phase models are shippedfrom factory with motor wired for 230 volts. If power supply is115 volts, remove motor canopy and reconnect motor asshown in Figure 4. Do not try to run motor as received on 115volt current.8. Motor has automatic internal thermal overload protection.

If motor has stopped for unknown reasons, thermal over-load may restart it unexpectedly, which could cause injuryor property damage. Disconnect power before servicingmotor.

9. If this procedure or the wiring diagrams are confusing,consult a licensed electrician.

PUMP SERVICEThis centrifugal pump requires little or no service other thanreasonable care and periodic cleaning. Occasionally, howev-er, a shaft seal (Key No. 4, Page 6) may become damagedand must be replaced. The procedure as outlined below willenable you to replace the seal.NOTICE: These mechanical seals are supplied with either arubber seat ring or a sealing O-Ring. They are completelyinterchangeable.NOTICE: The highly polished and lapped faces of this sealare easily damaged. Read instructions and handle the sealwith care.Some models are equipped with an impeller screw, which hasa left hand thread. Before unscrewing the impeller, removethe impeller screw.

REMOVAL OF OLD SEAL1. After unscrewing impeller (Key No. 5, Page 6), carefully

remove rotating part of seal by prying up on sealing wash-er, using two screwdrivers (see Figure 5A). Use care notto scratch motor shaft.

2. Remove seal plate (Key No. 3) from motor and place onflat surface, face down. Use a screwdriver to push ceram-ic seat out from seal cavity (see Figure 5B).

INSTALLATION OF FLOATING SEAT(Figure 5C)

1. Clean polished surface of floating (ceramic) seat withclean cloth.

2. Turn seal plate over so seal cavity is up; clean cavity thor-oughly.

3. Lubricate outside rubber surface or O-Ring of ceramicseat with soapy water and press firmly into seal cavity withfinger pressure. If seat will not locate properly in this man-ner, place cardboard washer over polished face of seatand press into seal cavity using a 3/4” socket or 3/4” pieceof standard pipe.

4. DISPOSE OF CARDBOARD WASHER. Be sure polishedsurface of seat is free of dirt and has not been damagedby insertion. Remove excess soapy water.

INSTALLATION OF ROTATING PART OFSEAL UNIT (Figure 5D)

1. Reinstall seal plate using extreme caution not to hit ceram-ic portion of seal on motor shaft.

2. Inspect shaft to make sure that it is clean.3. Clean face of sealing washer with clean cloth.4. Lubricate inside diameter and outer face of rubber drive

ring (see Figure 5D) with soapy water and slide assemblyon motor shaft (sealing face first) until rubber drive ring hitsshaft shoulder.

5. Screw impeller on shaft until impeller hub hits shaft shoul-der. This will automatically locate seal in place and movethe sealing washer face up against the facing seat.Reinstall impeller screw (if used).
