Recommendations and Warnings

Receiving inspection
Upon receiving the pump, it should be inspected for damage or shortages. If damage has occurred, file 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.

Controls
Manual models require a separate approved pump control device or  panel for automatic operation. Be sure the electrical specification of the control selected properly match the electrical specifications 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 (Figure 1).

Liquid Level Control

Typical Discharge Pipe Mounted:
Refer to Figure 2 below which shows a typical installation of a 1 phase 115 volt pump using a level control mounted to the discharge piping with a piggyback plug. 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 “Off” mode. By adjusting the cord tether the control level can be changed.

Typical Discharge Pipe Mounted Level Control

Level Control Basic instructions:
Plug the level control plug into the GFI receptacle, then plug the pump into the piggy-back plug ( Figure  3).
One cycle of operation should be observed, so that any potential problems can be corrected.

It is recommended that the level control float 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 6 Figure 1 inches above the basin floor.

Installation

These pumps are recommended for use in a sump or basin. The sump or basin shall be sealed and vented in accordance with local plumbing codes. This pump is designed to pump effluent or wastewater, nonexplosive and noncorrosive liquids and shall NOT be installed in locations classified 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 sufficient 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 flow volume.

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.

Installation & Service

Both a check valve and a shut-off valve are recommended for each pump. The check valve is used to prevent back flow into the sump. The shut-off valve is used to manually stop system low during pump servicing.

Electrical Connections

Power cable:
The power cable mounted to the pump must not be modified in any way except for shortening to a specific 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.

Always rely upon a Certified 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 effect of temperature and current.

This means that the overload protector will trip out and shut the pump off if the windings become too hot, or the load current passing through them becomes too high.

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 ALLOW THE PUMP TO 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.

TEMPERATURE SENSOR ELECTRICAL RATINGS

Volts| Continuous Amperes| Inrush Amperes
110-120| 3.00| 30.0
220-240| 1.50| 15.0

Wire Size:
If longer power cable is required consult a qualified electrician for  proper wire size.

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.
   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 filling 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:

• Inspect motor chamber for oil level and contamination.
• Inspect impeller and body for excessive build-up or clogging.
• Inspect motor, bearings and shaft seal for wear or leakage.

**Servicing

**

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 from housing. With a flashlight, visually inspect the oil in the housing 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, from housing.
• 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), refill 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 refilling with oil. To locate the leak, perform a pressure test.

After leak is repaired, dispose of old oil properly, and refill with new oil.

Pressure Test (If oil has been drained) – Remove pipe plug from housing. Apply pipe sealant to pressure gauge assembly and tighten into hole. Pressurize motor housing to 10 PSI. Use soap solution around the sealed areas and inspect joints for “air bubbles.

It after five minutes, the pressures 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 PSI. 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 five 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.

 Pressure builds up extremely fast, increase pressure by “TAPPING” air nozzle. Too much pressure will damage seal. DO NOT exceed 10 PSI.

Oil Replacement – Set unit upright and refill 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 (4).

DO NOT overfill oil.
Overfilling of housing with oil can create excessive and dangerous hydraulic pressure  which can destroy the pump
and create a hazard. Overfilling oil voids warranty.

1.  Poor electrical connection, blown fuse, tripped breaker or other interruption of power; improper power supply
2. Motor or switch inoperative (go to manual operation)
3. Float    movement    restricted 2b. Switch will not activate pump or is defective 2c. Defective motor
4. Insufficient liquid level

|

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.
2. Reposition pump or clean basin as required to provide adaquate clearance for float
3. 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)
4. 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.
5. Make sure liquid level is above the pump
6. Re-check all sizing calculations to determine proper pump size.
7. Check discharge line for restrictions, including ice if line passes through or into cold areas.
8. Remove and examine check valve for proper installation and freedom of operation.
9. Open valve
10. Check impeller for freedom of operation, security and condition. Clean impeller cavity and inlet of any obstruction.
11. Loosen union slightly to allow trapped air to escape. Verify that turn-off level of switch is set so that the suction is always flooded. Clean vent hole
12. Check rotation. If power supply is three phase, reverse any two of three power supply leads to ensure proper impeller rotation
13. Repair fixtures as required to eliminate leakage
14. Check pump temperature limits and fluid temperature
