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 (See Figure 1).

Installation

There are two methods of installing effluent pumps:

1. In a Flex-Hose system, most commonly used in interceptor tanks, and
2. A slide rail in a package system or concrete wet well, which allows the pump(s) to be installed or removed without requiring personnel to enter the wet well.

The sump, basin or lift station shall be sealed and vented in accordance with local plumbing codes. This pump is designed to pump sewage, effluent or wastewater, non-explosive and non-corrosive 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 is designed to pump sewage, effluent or wastewater, non-explosive and non- corrosive 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. Both a check valve and a shut-off valve are recommended for each pump. The check valve is used to prevent backflow into the sump. The shut-off valve is used to manually stop system low during pump servicing.

Liquid Level Controls
Typical Discharge Pipe Mounted: Refer to Figure 2 below which shows a typical installation of a 1 phase 120 or 240 volt pump using a level control mounted to the discharge piping with a piggy-back 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 Installation with Wide Angle Level Control

Level Control Basic Instructions: Plug the level control plug into the GFI receptacle, then plug the pump into the piggy-back plug (See 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 inches above the basin floor.

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 THHE 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. Check rotation on three phase units by momentarily applying power and observe the “kickback”.
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 (20), from housing (10).
• Check oil for contamination using an oil tester with a range to 30 kV 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 be carefully pump inspected for leaks at the shaft seal, conduit box, o-rings, pipe plug and pressure valve, before refilling with oil. To locate the leak, perform a pressure test.
• After leak is repaired, dispose of old oil properly, and re ill 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”.

If, after five 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 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 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 then assemble to housing.

• 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

Disconnect power. Remove cap screws and lock washers vertically lift motor, housing and seal plate assembly from volute. Clean out volute if necessary. Inspect gasket and replace if cut or damaged. Check U-cup for damage. If replacement is needed, cut the U-cup from the volute and clean surface of bore. Clean and examine impeller, for cracks or breakage and replace if required. To remove impeller, place a flat screwdriver in the slot of the end of the shaft to hold the shaft stationary while unscrewing the impeller.
To reassemble, clean the threads with thread locking compound cleaner. Apply removable Loctite® 242 or equivalent to shaft threads. Screw impeller onto the shaft hand tight while using a screwdriver in the slot at the end of the shaft to hold it stationary. Rotate impeller to check for binding. Install U-cup by applying adhesive to bore of volute. Be sure not to get adhesive on inside diameter of U-cup.
Position gasket on volute flange and position impeller and motor housing assembly on volute.
CAUTION Be sure the inside lip of the U-cup is not pushed out of place when assembling volute to rest of the pump.

Shaft Seal:
To examine or replace shaft seal, disassemble volute and impeller as stated. Remove retaining ring, spring and rotating member from shaft.
Inspect seal for signs of uneven wear pattern on stationary members, chips and scratches on either seal face. DO NOT interchange seal components, replace the entire shaft seal. If replacing seal, remove stationary by prying out with flat screwdriver.

Note: Handle seal parts with extreme care. Do NOT damage lapped surfaces.
To reassemble, clean seal cavity in seal plate and oil. Press seals stationary member firmly into seal plate, use a seal tool or pipe.
Nothing should come in contact with the seal face except the seal tool. Be sure the stationary is in straight. Lightly oil (Do not use grease) shaft and inner surface of bellows. Slide rotating member onto stationary using a seal tool. Place spring and retaining ring onto rotating member. Assemble impeller and volute as described.
Motor, Capacitor and Bearings: Remove volute and impeller as previously stated and drain oil from housing. Remove shaft seal. Position unit upright, using blocks to avoid resting unit on shaft. Unscrew cable cap screws and remove compression flange and power cord. Remove snap ring with a flat head screwdriver. Pull the terminal block out of the housing using a T-bolt or a pair of pliers and a .25-20 screw in the threads of the terminal block. Leave slack on the motor leads connected underneath. Use needle nose pliers to pull each female connector off of the pins on the underside of the terminal block. The voltage should be noted.

• Remove cap screws from seal plate and lift housing from seal plate.

• Remove square ring, replace if cut or damaged. Disconnect capacitor leads from capacitor. Remove motor bolts, lift cover, body and stator assembly from seal plate. Remove snap ring to
  remove rotor assembly. Remove bearings and with a wheel pulle.

• Check motor capacitor with an Ohm meter by first grounding the capacitor by placing a screwdriver across both terminals and then removing screwdriver. Connect Ohm meter (set on high scale) to terminals.

• If needle moves to infinity (oo) then drifts back, the capacitor is good.

• If needle does not move or moves to infinity (∞) and does not drift back, replace capacitor. Inspect motor winding for shorts and check resistance values. Check rotor for wear. If rotor or the stator windings are defective, the complete motor must be replaced.

• Slide rotor/shaft with bearings and into seal plate until bearing seats into seal plate. Install snap ring into seal plate.

• Place stator over rotor, lining up motor bolts with holes in seal plate.

• Place spring washer on bearing and cover onto rotor/stator assembly.

• Position capacitor so that it will lay on the opposite side of the cable entry boss of the housing. Install bracket and reconnect capacitor leads.

• Torque motor bolts to in/lbs. Set square ring in grove on seal plate.

• Lower housing down onto seal plate while aligning holes and stringing motor leads through the cord entry bore. Place cap screws through seal plate into housing and torque to 60 in/lbs. Reconnect motor leads to the underside of the terminal block.

• Place o-ring into groove in terminal block and lubricate with dielectric oil.

• Press the terminal block into the housing so it seats completely below the snap ring groove. Place snap ring into groove in cord entry bore of housing.

Power Cable Connection: Check power cord for cracks or damage and replace if required. Refill the cooling oil. Insert female end of cord plug into housing bore aligning
