Installation
Removing old pump (if necessary)
- Remove the old pump from the basin. If you need to cut the old discharge pipe to remove the pump, cut it as close to floor level as possible. If a check valve is attached to the pump, be prepared for water to leak from the pipe. Allow water to drain into the sump basin.
- Inspect the basin for accumulated mud, sand, silt or small stones. Clean out the basin if necessary.
Install new pump
- Connect the discharge pipe to the pump discharge. Do not use pipe joint compound on plastic pipe or plastic pump threads as this can degrade the plastic. Use Teflon® tape if necessary.
- Install a full flow, swing type check valve (sold separately) either directly into the pump discharge or on the discharge pipe. Make sure the check valve is positioned in the correct direction of flow.
- Place the pump on a solid, level surface in the basin. Use bricks or blocks to raise the pump off the bottom surface. Do not place the pump directly in mud, sand, silt or on rocky surfaces as these materials can clog or cause damage the pump. Do not lower the pump into the basin by the power cord or discharge pipe, use the attached handle.
- Position the pump in the basin making sure that the float switch will operate freely without coming in contact with the sides of the basin.
- Once the pump is positioned in the basin, mark and cut your existing discharge pipe to fit the height of the pump or continue installation of discharge pipe to the outside of the building.
Figure 1: Installation Diagram
A diagram illustrating a typical sump pump installation in a sump basin. It shows a grounded electrical outlet (A), the discharge pipe (B), a check valve (C), the sump basin (D), and the pump positioned with its float switch (E) operating freely without touching the basin walls. A GFCI outlet is recommended.
Operation
- Plug the piggy-back plug of the float switch into a 120 volt grounded outlet. The use of a GFCI is strongly recommended. Plug the pump plug into the back of the float switch plug. See Figure 2.
- Test your installation by filling the basin with water. Observe the float switch through at least one complete cycle to ensure it operates freely and does not contact the sides of the basin. If necessary, adjust the float switch or reposition the pump to ensure proper operation.
- This pump is equipped with an anti-airlock hole. A stream of water will emit from this hole when the pump is operating. This is a normal feature of this pump. The anti-airlock hole should be cleaned periodically to prevent the pump from becoming air locked.
- Do not let the pump run dry. The pump depends on water for cooling and lubrication. Operating the pump without water may cause the motor to overheat or cause damage to internal parts. It may also shorten the life of your pump.
- Your pump motor is thermally protected. It is not recommended for pumping liquids over 120° F (49°C). The thermal overload protector will automatically shut down the pump in an overheat situation. The pump will reset itself once the pump cools down. This overload is designed as a safety device and it will fail after repeated use. Normal operation is for fluids between 32° F & 120° F (0° C - 49° C).

Maintenance
❗ DANGER: Risk of electric shock. Always disconnect the power supply before attempting to install, service or perform maintenance on the pump.
❗ WARNING: All repairs must be made by an authorized service center.
⚠️ CAUTION: This submersible pump contains oil which may become pressurized and hot under normal operating conditions - allow the pump to cool for 2-3 hours before servicing.
- The pump motor is hermetically sealed in the housing and does not require any service. Disassembly of the motor housing or modification of the power cord voids the warranty.
- Periodically check the sump basin for accumulation of mud, silt, sand and foreign objects. Clean the basin as needed to prevent damage or clogging of the pump.
- Periodically check the removable intake screen for obstructions. Clean if necessary.
- Periodically inspect and clean the anti-airlock hole.
- Inspect the float switch for any accumulated debris that may inhibit it from operating properly. Clean if necessary.
- Inspect the impeller for signs of wear and obstructions.
- Inspect the power cord for signs of damage or wear. Do not operate the pump if the cord is damaged or worn.
- In applications where the pump may not activate for extended periods of time, it is recommended to cycle the pump at least once per month to ensure the pumping system is working properly when needed.
