Testing Automatic Pump Operation
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 will void the warranty.
If the pump does not operate properly, consult
found, please contact the place of purchase or an authorized service center.
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 outlined in the next sec-
tion. Do not let the unit freeze. This may cause cracking or distortion that may destroy the unit.
Testing Automatic Pump Operation
The 6EC-CIA-SFS and 10EC-CIA-SFS automatic pumps are equipped with an integral float-operated
mechanical switch. Automatic operation is achieved through the pump cord.
The 6EC-CIA-RF and 10EC-CIA-RF 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.
To test system operation, follow these steps:
1. Plug the power cord into a grounded receptacle with voltage consistent with the pump voltage, as indi-
cated on 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 attempt to run the pump without water; this could result in permanent damage to the pump.
4. Confirm that the pump and its control switch are functioning as intended.
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.
NOTE: It is normal for a stream of water to spray from the air bleed hole in the pump's plumbing.
(Water sprays out of a hole by a bolt on the base of the unit.) Confirm that this spray is captured within
the basin.
7. Allow the pump to operate through several on/off cycles.
