INTRODUCTION
This pump is suitable for installations where the vertical distance from the pump to the water level does not exceed 25 ft.(7.6m) *, including friction
loss. In o-set installations, friction losses in the suction pipe must be taken into consideration. *Varies with elevation above sea level.
SAFETY GUIDELINES
1. Make certain pump is disconnected from power source before attempting to service or remove any component.
2. Do not use to pump flammable or explosive fluids such as gasoline, fuel oil, kerosene, etc. DO NOT use in explosive atmospheres or hazardous
locations as classified by NEC, ANSI/NFPAT. Pump should be used with liquids compatible with pump component materials.
3. Do not handle the pump with wet hands or when standing on a wet or damp surface or in water.
4. Do not pull the pump out of the water by the power cord when the pump is operating or connected to power source.
5. This pump is supplied with a grounding conductor and/or grounding-type attachment plug. To reduce the risk of electrical shock, be certain that it
is connected to a properly grounded grounding-type receptacle.
6. In any installation where property damage and/or personal injury might result from an inoperative or leaking pump due to power outages,
discharge line blockage or any other reason, a backup system(s) and/or alarm should be used.
7. Support pump and piping when assembling and when installed. Failure to do so may cause piping to break, pump to fail, motor bearing failures, etc.
8. The pump motor is equipped with an automatic resetting thermal protector and may restart unexpectedly. Protector tripping is an indication of
motor overloading as a result of excessively high or low voltage, inadequate wiring, incorrect motor connections or a defective motor or pump.

INSTALLATION
A)PUMP LOCATION: The pump should be installed in a clean, dry and ventilated location which provides adequate drainage and room for servicing
and protection from freezing temperatures. It should be bolted down evenly on a good foundation, preferably concrete, to prevent the
development of unnecessary stress. Locating the pump as close as possible to the source of water supply reduces the friction losses in the suction
pipe and provides for maximum capacities.
B)SUCTION PIPE: It is recommended that only new clean pipe or hose be used and the size be the same as that of the pump suction tapping. If the
pump is installed any appreciable distance away from the source of water supply, the suction pipe should be increased by one size (this would
increase the priming time). The suction pipe must always slope upwards from the water source to the pump to avoid air pockets in the line. In
cases where the pump has to be re-primed often and it is not necessary that a lot of water be delivered, it is advisable to use a 90° or 45° elbow
on the suction line. This enables the pump to prime sooner and prevents kinking of the hose. In cases where a maximum volume of water is
required over a prolonged period, the suction line should be led almost horizontally to the pump. Thread compound should be used on all pipe
joints and connections should be thoroughly tightened. A strainer should be connected to the bottom end of the suction pipe and it should be
well submerged at all times.
C) WIRING: It is recommended that a separate circuit be used from the distribution panel to the pump unit. A properly fused disconnect switch is
to be installed in the line, making sure that the correct gauge of cable is used to carry the load. Very long leads will require a larger cable. An
electrician should be employed to do the wiring.

OPERATION
s
!
WARNINGDO NOT RUN THE PUMP BEFORE PRIMING IT; THE SEAL AND IMPELLER COULD BE PERMANENTLY DAMAGED.
A)PRIMING: Remove the priming plug located on the top of the pump casing and fill the casing with water. Replace the priming plug.
B)PRIMING UNDER PRESSURE (Figure 1): To prime under pressure, place a check valve on the discharge line of the pump and a petcock or a ball-type
air bleeder in place of the priming plug, or an air bleed line with a gate valve connected to the discharge line. The liquid can then remain in the
discharge pipe, allowing the pump to draw the air bleeder, thereby facilitating priming.
C) STARTING THE PUMP: Never operate the pump dry as this may damage the seal. If an exceptionally long suction line is used, the pump casing may
become overheated or vapor-locked. Should this occur, replace the water in the casing with cold water and continue priming.
D)DRAINING: Should the pump be subject to freezing temperatures, it will be necessary to drain the pump completely. To drain, remove the drain
plug (10) located at the bottom of the front face of the pump casing and the priming plug (11) and make sure that the drain hole is not choked.
After all the water has been drained, operate the pump for a few seconds to ensure that the impeller (4) is devoid of water. Make sure that the
suction line is also devoid of water.

TYPICAL INSTALLATION
1) EFFLUENT PUMP APPLICATION
IMPORTANT
A) Always follow local codes and requirements for proper installation in euent applications.
B) As alternates, pressure diaphragm switches or a mechanical float switch may be used. Ensure that the current and voltage specific cations match
those of the pump.
C) Many plumbers prefer not to use a strainer at the suction inlet as the strainer could clog. The pump is designed to handle the euent and though
it is advisable to use a strainer, it is not absolutely necessary.
2) SUMP PUMP APPLICATION
Clamp the switch to the suction pipe as shown in Fig. 1. Attach the float and wire assembly and adjust the position of the floats. As the water reaches
the top float, the pump will turn on; when it drops to the bottom float, the pump will turn o. Wire the pump and switch as shown in Fig. 5. Employ a
licensed electrician to do the wiring.

MAINTENANCE
LUBRICATION
• The pump requires no lubrication.
• For electric motor, refer to instructions provided by the motor manufacturer.
REPLACING MECHANICAL SEAL (Figure 2)
Disassembly:
• Disconnect electric power.
• Drain pump.
• Disconnect piping.
• Remove the 4 bolts (1) and take o the casing (2).
• Remove motor cap (8) and insert a screwdriver. Unscrew the impeller (4) in a counter-clockwise direction.
• Slip the rotating seal (5) from shaft (7) of seal plate/motor assembly.
• Remove seal plate (9) from the motor, being careful not to damage the ceramic seat (6).
• Inspect the ceramic seat (6). If it needs replacing, press it out of the adapter from the motor end.
Reassembly:
• Clean all parts thoroughly before reassembly. Use liquid soap on the rubber cup on the ceramic seat (6) and push it into the seal plate (9). Make sure
that the smooth surface of the ceramic seat faces outward.
• Assemble the seal plate (9) to the electric motor, being careful not to damage the ceramic seat (6).
• Use liquid soap on the rotating seal (5) and slip it on to the shaft (7) with the seal ring towards the ceramic seat (6). Make sure that the seal ring face
on the rotating seal contacts the ceramic seat.
• Screw on the impeller (4). Assemble the casing (2) and use a new gasket (3). Check to ensure that the impeller can rotate freely in the casing.
• Reconnect pump to suction and discharge hoses.
• All models have a flinger (12) on the shaft. This flinger must not be removed.
PRECAUTIONS
A)Whenever the pump is dismantled and then reassembled, always check to see that the impeller rotates freely within the casing.
A)Do not remove the flinger (12) from the shaft.

TROUBLESHOOTING
Pump fails to prime or primes slowly:
• Leaks in the suction line.
• Loose gasket connection due to shrinkage of the gasket.
• Collapsed or clogged suction line.
• Not enough water in the casing for priming.
• Suction lift is too great.
Reduced pressure or capacity:
• Partially collapsed or clogged suction hose.
• Clogged impeller.
• Leaks in the suction line.
• Strainer or end suction hose is not properly submerged.
• Suction line is improperly installed, resulting in air pockets in the suction line.
• Suction lift is too great. (The greater the suction lift, the lower the capacity and pressure.)
• Worn parts, such as the impeller or the pump casing.
Poor or little capacity:
• Improper impeller rotation. Impeller must rotate in a counterclockwise direction as seen facing the pump from the front of the casing.
