THE FOREGOING LIMITED WARRANTIES ARE EXCLUSIVE AND IN LIEU OF ALL OTHER EXPRESS AND IMPLIED WARRANTIES, INCLUDING BUT NOT LIMITED TO IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE FOREGOING LIMITED WARRANTIES SHALL NOT EXTEND BEYOND THE DURATION PROVIDED HEREIN.
Some states do not allow the exclusion or limitation of incidental or consequential damages or limitations on the duration of an implied warranty, so the above limitations or exclusions may not apply to You. This warranty gives You specific legal rights and You may also have other rights which vary from state to state.
This Limited Warranty is effective June 1, 2011 and replaces all undated warranties and warranties dated before June 1, 2011.

Installation

Risk of electric shock. Can shock, burn or kill. Do not lift pump by the power cord. See Cord Lift Warning.
NOTICE Install the pump on a hard, level surface (cement, asphalt, etc.). Never place the pump directly on earth, clay or gravel surfaces.
Piping
Piping must not be smaller than pump discharge. When installed in a sewage system, the pipe must be capable of handling semi-solids of at least 2” (51mm) in diameter.
When installed in an effluent system, the pipe must be capable of handling semi-solids of at least 3/4” (19mm) in diameter.
The rate of flow in the discharge pipe must keep any solids present in suspension in the fluid. To meet minimum flow requirements (2 feet per second in the discharge line), size the pipe as follows:

In a sewage system use a 2” (51mm) check valve (not included) in pump discharge to prevent backflow of liquid into sump basin. The check valve should be a free flow valve that will easily pass solids. Be sure check valve installation complies with local codes.
In an effluent system use a 1-1/2” (38mm) check valve (not included) in pump discharge to prevent backflow of liquid into sump basin. The check valve should be a free flow valve that will easily pass solids. Be sure check valve installation complies with local codes.
NOTICE For best performance of check valve when handling solids, do not install it with the discharge more than 45° above the horizontal. Do not install the check valve in a vertical position as solids may settle in the valve and prevent it from opening on startup. Drill a 3/16” (5mm) hole in the discharge pipe about 1–2” (25-51mm) above the pump discharge connection (but below check valve) to prevent relocking the pump.
Electrical
Risk of electric shock. Can shock, burn or kill. When installing, operating, or servicing this pump, follow the safety instructions listed below.

1. DO NOT splice the electrical power cord.
2. DO NOT allow the electrical cord plug to be submerged.
3. DO NOT use extension cords. They are a fire hazard and can reduce voltage sufficiently to prevent pumping and/or damage motor.
4. DO NOT handle or service the pump while it is connected to the power supply.
5. DO NOT remove the grounding prong from the plug or modify the plug. To protect against electrical shock, the power cord is a three-wire conductor and includes a 3-prong grounded plug. Plug the pump into a 3-wire, grounded, grounding-type receptacle. Connect the pump according to the NEC or CEC and local codes.

For automatic operation, plug or wire the pump into an automatic float switch or duplex controller. The pump will run continuously when plugged directly into an electrical outlet.
Connect or wire pump to its own individual branch circuit with no other outlets or equipment in the circuit. Size fuses or circuit breakers according to Motor, Switch and Cord Specifications.
Risk of electric shock. Can shock, burn or kill. Be sure that power supply information (Voltage/ Hertz/Phase) on pump motor nameplate matches incoming power supply exactly. Install pump according to all electrical codes that apply.

Cord Lift Warning

1. Attempting to lift or support pump by power cord can damage cord and cord connections.
2. Cord may pull apart, exposing bare wires with possibility of fire or electrical shock.
3. Lifting or supporting pump by power cord will void warranty.
4. Use lifting ring or handle on top of pump for all lifting/lowering of pump. Disconnect power to pump before doing any work on pump or attempting to remove pump from sump.

Operation Maintenance

Operation
Risk of fire and explosion. Can cause severe injury, property damage or death. Do not use in explosive atmospheres. Pump water only with this pump. NOTICE Do not allow the pump to run in a dry sump. It will void the warranty and may damage the pump. An automatic overload protector in the motor will protect the motor from burning out due to overheating/ overloading. When the motor cools down, the overload protector will automatically reset and start the motor. If the overload trips frequently, check for the cause. It could be a stuck impeller, wrong/low voltage, or an electrical failure in the motor. If an electrical failure in the motor is suspected, have it serviced by a competent repairman. The pump is permanently lubricated. No oiling or greasing is required.
Maintenance
General
Risk of electric shock. Can shock, burn  or kill. Before removing the pump from the basin for service, always disconnect electrical power to the pump and the control switch. Do not lift the pump by the power cord. See Cord Lift Warning.
After removing the basin cover and the necessary discharge piping, lift the pump out of the basin. Place the pump in an area where it can be cleaned thoroughly. Remove all scale and deposits on the pump. Submerge the complete pump in a disinfectant solution (dilute chlorine bleach) for at least one hour before disassembling the pump. The pump motor housing contains a special lubricating oil which should be kept clean and free of water at all times.
NOTICE Whenever the motor housing is being removed for service, remove oil and replace it with new oil at reassembly. Use only oil listed in parts list in this manual. When filling with new oil, DO NOT overfill. Allow about 7/8” (22mm) air space from top of boss in housing for expansion of oil when the pump is operating.

Pump Disassembly
See pump disassembly, Figure 1.

Figure 1 – Pump Disassembly

Impeller and seal replacement

1.  Remove the oil fill plug and turn the pump upside down to drain oil.
2. Remove the caps crews holding the upper motor housing to the lower motor housing; lift off the upper motor housing and remove the motor lead wires from the connector to detach upper housing from assembly. The lead wires are fitted with quick connect terminals for this purpose.
3. Remove the caps crews holding the lower motor housing to the volute; lift off the lower motor housing.
4. Hold the rotor shaft assembly and unscrew the impeller by turning it counter-clockwise. Remove impeller and clean it. If no more service is needed, reverse instructions above to reassemble the pump. Reattach the motor lead wires as shown in Figure 2, fill with clean SAE 5W-15W (ISO 22-44) mineral oil, check the oil level and replace fill plug. Oil should cover the top of the motor.

Shaft seal replacement

1. Follow the instructions to remove the impeller, above.

2. Remove the stator caps crews and the spacers (if applicable). Lift off the stator.

3. Remove the seal’s ceramic seat from the shaft and tap the body of the seal out of the lower motor housing.

4. Clean the seal cavity thoroughly before installing the new seal.
   NOTICE Make sure that the seal faces are clean; do not scratch or damage the new seal face during seal replacement. Apply gasket sealant sparingly to the outside edge of seal body before installing the seal in the lower motor housing.

5. Press the new seal body into position in the lower housing cavity.

6. Press the ceramic seat onto the motor shaft. The impeller will pull it into position.

7. Reassemble the stator and tighten the stator caps crews. If your pump has a capacitor (Repair Parts Ref. 11), be sure the spacer is under it to keep it away from the oil in the motor. Risk of electric shock. Can shock, burn or kill. Discharge capacitor before handling it. Electrical shock can burn or kill.

8. Reassemble the impeller and the pump (reverse instructions 1 through 4 in Impeller And Seal Replacement).

9. Install new capacitor.

10. Reattach the motor lead wires as shown in Figure 2.

11. Fill with fill with clean SAE 5W-15W (ISO 22-44) mineral oil, check the oil level and replace the oil fill plug.

Troubleshooting

Risk of electrical shock, cuts, and possible unexpected starts. If the power is on to the pump when thermal overload resets, the pump may start without warning. If you are  working on the pump, you may get an electrical shock or the impeller may catch fingers or tools. Disconnect the power before servicing the pump.

plugged into outlet or securely wired into controller or switch box. Disconnect power to outlet before handling pump or motor.
2.| Check to be sure you have electrical power.
