- When the plug is inserted into the socket, the pump will be on standby.
- WARNING: To prevent death from electric shock, pump must be connected only to a GFCI protected outlet.
- WARNING! 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 to pump water only.
- This pump is designed to be used for: Pumping drinking water from shallow wells and cisterns. Irrigation systems.
- This pump should NOT be used for: Continuous run, fountain/pond water features. Water with dirt and debris.
- This pump can also be used to transfer water (e.g. household, farming, plumbing).
- Do not use as a booster pump in a city water system.
Installation Instructions
This pump is designed for use as a well pump.
WARNING! TO PREVENT SERIOUS INJURY FROM ELECTRIC SHOCK: Install indoors or in weather-proof well house only. This Pump is non-submersible. Do not plug in the power cord when wet or standing on damp or wet ground. Do not plug in the power cord until instructed to do so.
NOTE:
- ONLY pump clean water.
- Additional components (such as valves and pipes) may be required for installation, but not included.
- Installation requires skilled workmanship and compliance with local building codes. If you are not confident in your ability to properly and safely install this pump, have a qualified technician perform the installation.
- The water to be pumped must be clean and must be free of sand and grit, which would damage the pump and void the warranty.
1. The illustration below shows an example of a proper shallow well pump installation. The total suction lift (vertical well lift + length of off-set line) must not exceed Maximum Suction Lift.
Note: This pump is intended for shallow well application only and is not intended to be used as a booster pump.
Note: For optimal performance, install the pump as close to the well head as possible.
2. Install a Foot Valve at the bottom of the suction pipe. The Foot Valve must be under the Pumping Water Level, the level that the water falls to when the pump operates.
3. Install a sterile Well Seal at the top of the suction pipe to keep the well clean. Protect from rust inside a frost-proof enclosure.
4. Intake and discharge pipes must be at least 1 inch in diameter.
5. Lay an off-set line from the well to the structure the pump will be installed in. The off-set line should slope slightly towards the well. Systems with longer off-set lines should use larger diameter pipe to improve efficiency.
6. Install the pump on a rigid, level, dry platform. This platform must provide a solid, level surface that is capable of supporting the weight of the pump and attached piping filled with water. Do not allow water to contact the pump's housing.
NOTICE: DO NOT INSERT fittings into the Intake Hole farther than 1/2 inch; this can DAMAGE the Pump, diminish Pump functions, and/or STOP water flow.
7. To prevent leaks, use metal fittings for all pipe connections to pump ports. Do not use plastic fittings.
8. Keep the Head, the height that the pump discharge must push water before discharge, to a minimum. The Vertical Well Lift, Off-set Line Length, and Head added together must be less than Maximum Delivery Height to have flow at output. Effective flow decreases to 0 GPH as Maximum Delivery Height reaches its maximum.
9. For your protection, the power outlet used should have a Ground Fault Circuit Interrupter (GFCI). Have it installed by a qualified electrician. Keep power line away from water.
10. The inlet and discharge lines should not be wedged or stressed in a way that puts strain on the pump. Do not support the pump with the inlet or discharge lines.
Pump Setup Example Diagram Description
The diagram illustrates a typical shallow well pump installation. It shows the water level in the well, the shallow well pump itself, a suction pipe with a foot valve submerged at the bottom, and a well seal at the top of the suction pipe. An off-set line connects the well to a household water system, passing through a check valve. The diagram indicates how to calculate the total suction lift, which includes the vertical well lift and the length of the off-set line, and notes that this total must not exceed the maximum suction lift. It also shows the pumping water level and the standing water level.
Operation & Maintenance
Operation
After reading these instructions, consider the following points before starting the pump:
- The Compression Tank has a rubber bladder inside that has been pressurized to 23 PSI. Air can be added using a bicycle pump.
- Make sure the intake pipe is fully submerged before continuing.
- Before starting the pump for the first time, prime it as follows:
- a. Fill the suction Pipe and Pump Body through the Priming Inlet.
- b. Close the Inlet after verifying that there are no leaks.
- c. Open the spigots, faucets and/or taps on the Delivery Pipe so that air can be released from the suction cycle.
- This is a self-starting pump that uses a pressure switch. Once the power cord is connected, the pump can start at any time. Do not handle or perform maintenance on the pump if the power cord is plugged in.
- Verify that the pump rests on the floor of the basin, if it is not suspended by the handle.
- Verify that the discharge pipe is properly connected.
- Verify that the electrical connection is 230 VAC, 50 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.
- Run pump for two minutes. If it fails to pump water, disconnect power, re-fill pump body through priming inlet and re-start.
- To begin pumping, plug in the power cord. When the line is pressurized, the pump will go to standby mode until the pressure falls below its starting pressure.
Maintenance
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 the inlet screen on the intake port regularly to remove accumulated debris.
- Wipe the pump clean with a soft, damp cloth with soapy water. Do not use solvents. Do not get the electrical components wet.
- Drain water from pump before storage by disconnecting the water lines and turning the Pump upside down. If storing the pump for a long time, store it in a dry location, and apply a light layer of oil to the metal parts prior to storage, to inhibit rust. Do not expose to freezing temperatures.
- After storage, check the Impeller to make sure it turns easily and is not oxidized.
