OPERATION TESTING
Testing Automatic Pump Operation

If the unit is going to be idle for a period of time, follow the cleaning instructions outlined in
Impeller and Volute” on page 9
. Do not let the unit freeze. This may cause cracking or distortion that may
destroy the unit.
Testing Automatic Pump Operation
The 9EC-CIA-SFS, 9ECH-CIA-SFS, and 10ECH-CIA-SFS automatic pumps are equipped with an integral float-
operated mechanical switch. Automatic operation is achieved through the pump cord.
The 9EC-CIA-RF, 9EC-CIA-RF, and 10ECH-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 float 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. Con
-
firm that this spray is captured within the basin.
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 piggyback plug while raising and lowering the float.
