Receiving & Installation

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. Do not pump out of liquid.

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).

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 (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.

Installation
These pumps are recommended for use in a sump or basin. The sump or basin shall be sealed and vented in 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 backflow 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 flow during pump servicing.

Electrical Connections Power cable
The power cable mounted to the pump must not be modified in any way. This pump is provided with a 3 wire cord and 3 prong grounded plug that must be connected into a 3 wire grounded Ground Fault receptacle. Do not bypass grounding wires or remove ground prongs from plug. This pump requires separate, properly fused and grounded branch circuit. Use of a ground fault circuit interrupter (GFCI) is strongly

IF USED with Control Panel – 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. If current through the temperature sensor exceeds the values listed, an

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

Maintenance

No lubrication or maintenance is required. Perform the following checks when pump is removed from 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
• After leak is repaired, dispose of old oil properly, and refill with new oil.
• 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.

Power Cord and Motor

1. emove pipe plug and drain oil from housing.
2. Remove gland nut, washer and nylon housing from motor housing. Pull cord through and disconnect the wires from the terminals on power cord.
3. Remove snap ring from seal plate. Remove shaft and motor rotor from seal plate.
4. Remove seal’s rotating member, spring and retaining ring from seal plate. Examine all seal parts, if seal faces show signs of wear, uneven wear pattern, chips or scratches replace entire seal. DO NOT interchange seal components, replace the entire shaft seal. If replacing seal, remove stationary by prying out with flat screw drive.

Bearings
Examine lower bearing, and upper bearing, if replacement is required, remove by using a wheel puller.

IMPORTANT! – All parts must be clean before reassembly. Handle seal parts with extreme care. DO NOT damage lapped surfaces.

Bearings

1. Press bearings and onto shaft. Shaft Seal:

2. Clean seal cavity in seal plate and oil. Press seal’s 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.

3. lace seal’s retaining ring, spring being carefull not to damage seal face. Make sure spring is seated in retaining ring and spring is lined up on rotating member and not cocked or resting on bellows tail.
   Motor:

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

5. Lower housing while stringing motor leads through the cord entry bore, with motor stator onto seal plate.

6. Place screws with washers through housing into seal plate and torque to 60 in/lbs.

7. Check power cord for cracks or damage and replace if required. Reconnect motor leads.

8. Place power cord with nylon housing, ring, washer and gland nut into housing and tighten gland nut to 17.5 ft/lbs.

9. Position v-ring into seal plate until seated.

10. lean 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
