Receiving & Installation

Receiving Inspection

Upon receiving the pump, it should be inspected for damage or shortages. If damage has occurred, le a claim immediately with the company that delivered the pump. If the manual is removed from the packaging, do not lose or misplace.

Storage

Any product that is stored for a period longer than six (6) months from the date of purchase should be bench tested prior to installation. A bench test consists of, checking the impeller to assure it is free turning and a run test to assure the motor (and switch if provided) operate properly. Do not pump out of liquid.

Controls

Manual models require a separate approved pump control device or panel for automatic operation. Be sure the electrical speci cation of the control selected properly match the electrical speci cations of the pump.

Submergence

The pump should always be operated in the submerged condition. The minimum sump liquid level should never be less than above the pump’s volute (See Figure 1).

Installation

These pumps are recommended for use in a sump, basin or lift station.

The sump, basin or lift station shall be sealed and vented in accordance with local plumbing codes. This pump is

designed to pump sewage, e uent or wastewater, nonexplosive and noncorrosive liquids and shall NOT be installed in locations classi ed as hazardous in accordance with the National Electrical Code (NEC) ANSI/ NFPA 70 or Canadian Electric Code (CEC). The pump should never be

installed in a trench, ditch, or hole with a dirt bottom. The legs will sink into the dirt and the suction will become plugged.

The installation should be at a su cient depth to ensure that all plumbing is below the frost line. If this is not feasible, remove the check valve and size the basin to accommodate the additional back ow volume.

Pumps are most commonly installed in simplex or duplex stations or basins with a slide rail system, which allows the pump(s) to be installed or removed without requiring personnel to enter the station, or resting on the basin  oor.

Liquid Level Controls

The level control(s) should be mounted on the discharge piping, a cable rack or  oat pole. The level control should have adequate clearance so it cannot hang up in it’s swing and that the pump is completely submerged when the level control is in the “O ” mode. By adjusting the cord tether the control level can be changed. One cycle of

operation should be observed, so that any potential problems can be corrected.

It is recommended that the level control  oat should be set to insure that the liquid in the sump never drops below the top of the motor housing or a minimum level of 10 inches above the basin  oor.

Electrical Connections

Power cable:

The power cable mounted to the pump must not be modied in any way except for shortening to a specic application. Any splice between the pump and the control panel must be made in accordance with the electric codes. It is recommended that a junction box, if used, be mounted outside the sump or be of at a minimum Nema 4 construction if located within the wet well. DO NOT USE

THE POWER CABLE TO LIFT PUMP.

Bottom of Feet

Figure 1

Discharge Piping

Discharge piping should be as short as possible and sized no smaller than the pump discharge. Do not reduce

the discharge pipe size below that which is provided on the pump. Both

a check valve and a shut-o valve are recommended for each pump. The check valve is used to prevent backow into the sump. The shut-o valve is used to manually stop system ow during pump servicing.

Power-Flo Pumps & Systems • 877-24PUMPS • www.power opumps.com

Always rely upon a Certi ed Electrician for installation.

Overload Protection: Single Phase - The stator in-winding

overload protector used is referred to as an inherent overheating protector and operates on the combined e ect of temperature and current. This means that the overload protector will trip out and shut the pump o if the windings become too hot, or the load current passing through them becomes too high.

Installation & Service

IMPORTANT ! - The overload will then

automatically reset and start the pump up after the motor cools to a safe temperature. In the event of an overload, the source of this condition should be determined and corrected immediately.

WARNING! - DO NOT LET THE PUMP CYCLE OR RUN IF AN OVERLOAD CONDITION OCCURS !

If current through the temperature sensor exceeds the values listed, an intermediate control circuit relay must be used to reduce the current or the sensor will not work properly.

Pre-Operation

1. Check Voltage and Phase - Compare the voltage and phase information stamped on the pump name plate.

2. Check Pump Rotation - Improper motor rotation can result in poor pump performance and can damage the motor and/or pump. Check rotation on three phase units by momentarily applying power and observe the “kickback”.

Kickback should always be in a counter-clockwise direction as viewed from motor end or opposite to impeller rotation. Incorrect rotation for Single-Phase pumps is unlikely. If the rotation is incorrect contact factory.

3. Name Plate - Record the information from the pump name plate to drawing in front of manual for future reference.

4. Insulation Test - An insulation (megger) test should be performed on the motor. Before the pump is put into service. The resistance values (ohms) as well as the voltage (volts) and current (amps) should be recorded.

5. Pump-Down Test - Be sure pump has been properly wired, lowered into the basin, sump or lift station, check the system by lling with liquid and allowing the pump to operate through its pumping cycle. The time needed to empty the system, or pump-down time along with the volume of water, should be recorded.

Maintenance

No lubrication or maintenance is required. Perform the following checks when pump is removed from operation or when pump performance deteriorates: a). Inspect motor chamber for oil level and contamination. b). Inspect impeller and body for excessive build-up or clogging. c). Inspect motor, bearings and shaft seal for wear or leakage.

Servicing

NOTE: Item numbers in ( ) refer to Figures 6 through 9.

Cooling Oil - Anytime the pump is removed from operation, the cooling oil in the motor housing should be checked visually for oil level and contamination. To check oil, set unit upright. Remove pipe plug (20) from housing (4). With a ashlight, visually inspect the oil in the housing (4) to make sure it is clean and clear, light amber in color and free from suspended particles. Milky white oil indicates the presence of water. Oil level should be just above the motor when pump is in vertical position.

Oil Testing

• Drain oil into a clean, dry container by placing pump on it’s side, remove pipe plug (20), from housing (4).

• Check oil for contamination using an oil tester with a range to 30 Kilovolts breakdown.

• If oil is found to be clean and uncontaminated (measuring above 15 KV. breakdown), rell the housing.

• If oil is found to be dirty or contaminated (or measures below 15 KV. breakdown), the pump must be carefully inspected for leaks at the shaft seal, cable assembly, square ring and pipe plug, before relling with oil. To locate the leak, perform a pressure test.

After leak is repaired, dispose of old oil properly, and rell with new oil.

Pressure Test (If oil has been drained)

Service

If, after ve minutes, the pressure is still holding constant, and no “bubbles” are observed, slowly bleed the pressure and remove the gauge assembly. Replace oil. Leek must be located and repaired if pressure does not hold.

Pressure Test (If oil has NOT been drained) - Oil should be at normal level.

Remove pipe plug (20) from housing (4). Apply pipe sealant to pressure gauge assembly and tighten into hole. Pressurize motor housing to 10 P.S.I. Use soap solution around the sealed areas above the oil level and inspect joints for “air bubbles”. For sealed areas below oil level, leeks will seep oil. If, after ve minutes, the pressure is still holding constant, and no “bubbles” /oil seepage is observed, slowly bleed the pressure and remove the gauge assembly. Replace oil. Leek must be located and repaired if pressure does not hold.

Oil Replacement - Set unit upright and rell with new cooling oil as per table below . Fill to just above motor, but below capacitor as an air space must remain in the top of the housing to compensate for oil expansion. Apply pipe thread compound to threads of pipe plug (20) then assemble to housing (14.

DO NOT overll oil. Overlling of housing with oil can create

excessive and dangerous hydraulic pressure which can destroy the pump and create a hazard.

Overlling oil voids warranty.

Trouble Shooting Chart

Risk of electric shock. Always disconnect the pump from the power source before handling inspections or repairs.

Symptom Possible Cause(s) Corrective Action

1. Poor electrical connection, blown fuse, tripped breaker or other interruption of power; improper power supply

2. Motor or switch inoperative (go to manual

Pump will not run

Pump will not turn o

Pump hums but doesn’t run

Pump delivers insu cient capacity

Pump cycles too frequently or runs periodically when  xtures are not in use

Pump shuts o and turns on independent of switch, (trips thermal overload protector). CAUTION! Pump may start unexpectedly. Disconnect power supply.

Pump operates noisily or vibrates excessively

NOTE: Power-Flo Pumps & Systems assumes no responsibility for damage or injury due to disassembly in the  eld. Disassembly of the pumps or supplied accessories other than at Power-Flo Pumps & Systems or its authorized service centers, automatically voids warranty.

operation) 2a. Float movement restricted 2b. Switch will not activate pump or is defective 2c. Defective motor

3. Insu cient liquid level

2a. Float movement restricted 2b. Switch will not activate pump or is defective

4. Ecessive in ow or pump not properly sized for application

9. Pump may be air locked causing pump not to  ow

14. H-O-A switch on panel is in “HAND” position

1. Incorrect low voltage

8. Impeller jammed or loose on shaft, or inlet plugged

1. Incorrect low voltage

4. Ecessive in ow or pump not properly sized for application

5. Discharge restricted

6. Check valve partially closed or installed backwards

7. Shut-o valve closed

8. Impeller jammed or loose on shaft, or inlet plugged

9. Pump may be air locked causing pump not to  ow

10. Piping  xtures leaking or discharge before the nozzle

6. Check valve partially closed or installed backwards

11. Fixtures are leaking

15. Ground water entering basin

1. Incorrect low voltage

4. Ecessive in ow or pump not properly sized for application

8. Impeller jammed or loose on shaft, or inlet plugged

12. Excessive water temperature (internal protection only)

2c. Worn bearings, motor shaft bent

5. Debris in impeller cavity or broken impeller

10. Pumprunning backwards

13. Piping attachments to building structure too loose or rigid

1. Check all electrical connections for security. Have electrician measure current in motor leads, if current is within ± 20% of locked rotor Amps, impeller is probably locked. If current is 0, overload may be tripped. Remove power, allow pump to cool, then re-check current. 2a. Reposition pump or clean basin as required to provide adaquate clearance for  oat 2b. Disconnect level control. Set ohmmeter for a low rang, such as 100 ohms full scale and connect to level control leads. Actuate level control manually and check to see that ohmmeter shows zero ohms for closed switch and full scale for open switch. (Float Switch) 2c. Check winding insulation (Megger Test) and winding resistance. If check is outside of range, dry and re-check. If still defective, replace per service instructions.

3. Make sure liquid level is above the pump

4. Re-check all sizing calculations to determine proper pump size.

5. Check discharge line for restrictions, including ice if line passes through or into cold areas.

6. Remove and examine check valve for proper installation and freedom of operation

7. Open valve

8. Check impeller for freedom of operation, security and condition. Clean impeller cavity and inlet of any obstruction

9. Loosen union slightly to allow trapped air to escape. Verify that turn-o level of switch is set so that the suction is always  ooded. Clean vent hole

10. Check rotation. If power supply is three phase, reverse any two of three power supply leads to ensure proper impeller rotation

11. Repair  xtures as required to eliminate leakage

12. Check pump temperature limits and  uid temperature

13. Replace portion of discharge pipe with  exible connector or tighten existing piping.

14. Turn to automatic position

15. Check for leaks around basin inlet and outlets
