piggyback plug while raising and lowering the float.
2. Remove the rubber plug on the basin cover in order to observe switch operation.
3. Plug the power cord into a grounded receptacle with voltage indicated on the pump nameplate.
4. Be sure the valve in the discharge line is open.
5. Run water into the basin until the pump is activated.
6. Make sure the pump and its float switch are functioning as intended.
• Confirm that no potential obstructions exist that could inhibit switch operation.
• Verify the ON/OFF levels are within specification.
7. Confirm that there are no leaks in the pump discharge
plumbing and main home drain pipe plumbing.
8. Allow the pump to operate through several ON/OFF
cycles.
