Testing Automatic Pump Operation

OPERATION
Risk of personal injury or damage to pump or other equipment.
• This pump is equipped with a cutting mechanism that has very sharp edges. Use caution when
working on or near these parts. Do not allow anything to enter the pump during testing.
• The float or ball portion of the switch must not touch the pump, the walls of the basin, the plumbing,
or any wiring in the basin as it floats up or down. Contact with obstacles may cause the pump to
continue running without water or to stop running when water is present, damaging the pump or
other property.
• 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.
Testing Automatic Pump Operation
Some pumps have automatic switches with piggyback plugs on the switch cords. The pump must be
plugged into piggyback switch cord for automatic operation.
When these pumps are installed in a basin with a sealed cover, switch 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
switch operation can be observed.
1. Connect the pump to power with correct voltage. Refer to the pump nameplate.
2. Be sure the gate valve in the discharge line is open.
3. Run water into the basin until the pump is activated. Do not run pump without water.
4. Ensure the pump and its control switch are functioning as intended.
5. Confirm the ON/OFF levels are within specification.
6. Make sure no potential obstructions exist that could inhibit switch operation.
7. Verify that there are no leaks in the pump discharge plumbing and main home drain pipe plumbing.
NOTE: It is normal for a stream of water to spray from the air bleed hole in the pump's plumbing. Con-
firm that this spray is captured within the basin.
8. Allow the pump to operate through several ON/OFF cycles.
