OPERATION TESTING

Risk of damage to pump or other equipment.
• Do not attempt to run the pump without water; this could result in permanent damage to the pump.
• If pump is run dry, it may damage pump and void the warranty.
If the pump does not operate properly, refer to
found, please contact the place of purchase or Technical Support at 888-885-9254.
Do not let the unit run dry (without liquid). It is designed to be cooled by pumping fluid. The seal may be
damaged and the motor may fail if the pump is allowed to run dry.
If the unit is going to be idle for a period of time, follow the cleaning instructions in
Volute" on page 8. Do not let the unit freeze. This may cause cracking or distortion that may destroy the
unit.

Testing Pump Operation

Pumps are equipped with a tethered or vertical float switch that operate by floating on top of accumulating
water. Rising water in the basin lifts the float, which activates the switch, turning on the pump. As the water
level falls, the float lowers until the switch deactivates, turning off the pump.
When the pump is installed in a basin with a sealed cover, pump operation cannot be observed. The basin
cover will usually have a spare hole that is plugged with a rubber plug. This plug can be removed and pump
operation can be observed.
To test system operation, follow these steps:
1. Connect the float switch and pump to an appropriate power supply with voltage consistent with the
pump voltage, as indicated on the pump nameplate.
2. If there is a gate valve on the discharge line, be sure the valve is open.
3. Run water into the basin until the pump is activated. Do not attempt to run the pump without water;
this could result in permanent damage to the pump.
4. Confirm that the pump and its float switch are functioning as intended.
NOTE: If the pump doesn't turn on, test manual operation by connecting the pump's power plug
directly into the power source. If the pump runs, test the float switch.
5. Confirm that the ON/OFF levels are within specification, and confirm that no potential obstructions
exist that could inhibit switch operation.
6. Confirm that there are no leaks in the pump discharge plumbing and main home drain pipe plumbing.
7. Allow the pump to operate through several on/off cycles.
Testing the Float Switch
A float switch can be bench tested by using an ohmmeter to check for
continuity between the incoming and outgoing connections of the pig-
gyback plug while raising and lowering the float.
