Important Safety Information
WARNING: Read this material before using this product. Failure to do so can result in serious injury. SAVE THIS MANUAL.
CAUTION: This pump has been evaluated for use with water only.
Before start-up, note the following: The pump must be connected to a GFCI protected plug installed according to regulations. The plug must have a supply voltage of 120 VAC at 60 Hz.
Safety Precautions:
- Risk of electric shock: This pump is supplied with a grounding conductor and grounding-type attachment plug. Connect only to a properly grounded, grounding-type receptacle.
- This pump has not been investigated for use in swimming pool areas.
- Electrical connections must be protected from moisture.
- If there is danger of flooding, electrical connections must be taken to higher ground.
- Avoid circulation of caustic fluids and abrasive materials.
- The pump must be protected from frost.
- The pump must be protected from running dry.
- Prevent access by children with appropriate measures.
- To prevent death from electric shock, the pump must be connected only to a GFCI protected outlet.
- Do not use an extension cord with this item.
- People with pacemakers should consult their physician(s) before use, as electromagnetic fields in close proximity to pacemakers could cause interference or failure.
- The warnings, precautions, and instructions in this manual cannot cover all possible conditions and situations. Common sense and caution are factors that must be supplied by the operator.
Fluid Type
The pump is designed for use with water with a maximum temperature of 131° F (55°C). Do not use the pump for other fluids, especially fuels, cleaning fluids, or other chemical products.
Specifications
| Electrical Rating | 120VAC / 60Hz / 8.5A |
| Power Cord Length | 10' |
| Maximum Flow @ 0' | 6000 GPH |
| Maximum Head lift @ 0 Flow | 18' |
| Discharge Port | 2" NPT Thread |
Installation
The submersible motor pump must be installed in a stationary position with either:
- a. A fixed pipeline or
- b. A flexible hose pipe.
Please note!
- Do not install the pump by suspending it unsupported from its delivery pipe or power cord. Suspend the pump from the handle or place it on the bottom of the basin.
- To ensure proper operation, keep the bottom of the basin free from sludge and dirt.
- If the water level sinks too low, sludge in the basin may dry out and stop the pump from starting. Check the pump regularly with start-up tests.
Power Supply
- The pump is equipped with a shock-proof plug according to regulations and is designed for connection to a 120 VAC, 60 Hz GFCI protected socket.
- Ensure the socket is sufficiently secured and in excellent condition.
- When the plug is inserted into the socket, the pump will be on standby.
- WARNING: To prevent death from electric shock, the pump must be connected only to a GFCI protected outlet.
- WARNING! TO PREVENT SERIOUS INJURY: If the power cord or plug is damaged, do not use the pump. The power cord or plug may only be repaired by a certified electrician.
Areas of use
- This pump is designed for pumping domestic sewage, effluent, wastewater, groundwater, and other nonexplosive, noncorrosive liquids with up to 2" diameter solids to a gravity-fed sewage line.
- This pump should NOT be used for continuous run fountain/pond water features or for removing water from swimming pools or spas.
Installation Instructions
- Construct a basin that is at least 30" deep and at least 18" in diameter.
- Position the pump on a solid surface so that both hoses are free from kinks, the Float Switch is away from the inlet pipe and at least 1" away from all obstructions throughout its movement.
- Fit a sewage cover with a vent pipe, a hole for the output pipe, and a hole for the power cords. Thread the power cords through their holes, but do not plug them in yet. Set the sewage cover aside. Place the unused end of the discharge hose the other end. Note: The sewage cover must also be fitted with a vent pipe.
Figure A: Sewage Basin illustrates the basin construction.
Figure B: Pump Position illustrates the correct placement of the pump within the basin.
Figure C: Outlet Pipe and Plug illustrates the outlet pipe connection.
- Attach a discharge pipe to the Pump Outlet. Note: Wrap all threaded connections with PTFE thread seal tape.
- Check Valve is sold separately. Install according to manufacturer instructions.
- To prevent excessive cycling from backflow of water, install a check valve onto the discharge pipe. This prevents water from flowing back after the pump shuts off. Mount the check valve according to the valve label to avoid the valve flapper getting stuck.
- Connect additional Discharge Pipe as needed to direct the discharge to the main waste line for the sewer or septic tank. Keep the discharge pipe as short as possible with a minimum number of turns.
- IMPORTANT: Drill a 1/8" diameter air bleed hole through the Discharge Pipe just above the lower Base to prevent Pump "airlock". A small spray of water out of this hole is normal while the Pump is running.
- IMPORTANT: Do not exceed the Maximum Head Lift @ 0 Flow of the Pump.
Operation
After reading these instructions, consider the following points before starting the pump:
- Verify that the pump rests on the floor of the basin.
- Verify that the discharge pipe is properly connected.
- Verify that the electrical connection is 120 VAC, 60 Hz.
- Verify that the electrical socket is GFCI protected and in good condition. Test GFCI protected outlet before use.
- Verify that water and moisture cannot get near the power supply socket.
- Verify that the pump is installed so as to prevent running dry.
Maintenance
WARNING: TO PREVENT SERIOUS INJURY FROM ACCIDENTAL OPERATION: Unplug the Pump from its electrical outlet before performing any inspection, maintenance, or cleaning procedures.
If the pump is moved during operation, flush it out with clean water after every use.
Quarterly Maintenance
The below maintenance must be performed at least once every 3 months under optimal conditions. For frequent use, or dirty areas, more frequent maintenance is required.
- Clean sludge and debris from the bottom of the basin.
- Clean sludge/debris from inlet screen.
- Make sure discharge pipe is free from leaks.
- Make sure check valve is functioning properly.
- Manually operate flow switch to determine that pump turns on/off as intended.
Troubleshooting
| Problem | Possible Causes | Possible Solutions |
|---|---|---|
| Pump runs, but will not deliver any water. | Disconnect power cords immediately to prevent damage from running dry. 1. Pump "airlock". The impeller is trapped in an air bubble. 2. Shut off valve closed (if installed). 3. Impeller clogged. 4. Discharge Pipe frozen or blocked. 5. Low line voltage. 6. Check valve (sold separately) stuck or installed backwards. | Disconnect power cords immediately to prevent damage from running dry. 1. Drill a 1/8" diameter air bleed hole through the Discharge Pipe just above the lower Base. Make sure air bleed hole is clear. 2. Open valve. 3. Clean out dirt and debris from impeller. 4. Thaw pipe and/or remove debris. 5. Consult an electrician. 6. Remove and examine check valve. |
| Pump won't start or run. | 1. Check power connections and circuits/fuses. 2. Float Switch failed. 3. Impeller clogged. 4. Defective motor. | 1. Consult an electrician. 2. Replace Float Switch. 3. Clean out dirt and debris from impeller. 4. Have a qualified service technician repair or replace. |
| Excessive noise or vibration. | 1. Worn bearings. 2. Debris in impeller. 3. Discharge pipe restricted. | 1. Have a qualified service technician repair or replace. 2. Clean impeller. 3. Clean Pump and discharge pipe. Straighten flexible hose. |
| Pump starts and stops too frequently. | 1. Water temperature too high. 2. Check valve (sold separately) stuck or installed backwards. 3. Back flow of water from discharge hose. | 1. Do not exceed 131° F (55°C) water temperature. 2. Remove and examine check valve. 3. Install or inspect check valve (sold separately). |
| Pump does not shut off automatically | DISCONNECT POWER CORDS FIRST TO PREVENT ACCIDENTAL STARTING. 1. Float Switch stuck. 2. Check valve not installed properly or functioning. 3. Defective electrical switch. | DISCONNECT POWER CORDS FIRST TO PREVENT ACCIDENTAL STARTING. 1. Check for free movement of Float Switch. Clear debris away from beneath Float Switch. 2. Make sure check valve is properly installed and in working order. 3. Unplug Pump from its electrical outlet. Do not use until qualified technician checks Pump for damage. |
