Testing Automatic Pump Operation

The 9SC-CIA-SFS and 10SC-CIA-SFS automatic pumps are equipped with an integral float-operated
mechanical switch which will turn the pump on when water level reaches the levels shown in the Specifica-
tions tables. Automatic operation is achieved through the pump cord.
The 9SC-CIA-RF and 10SC-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 pig-
gyback plug while raising and lowering the float.

Testing Manual Pump Operation

Pumps with -CIM in the model name are manual pumps.
Risk of bodily injury or damage to pump or other equipment.
•
Manual, continuous pump operation should be used only for emergencies, or when a large volume
of water is to be pumped. The pump must be continuously monitored during operation and
disconnected from power before the pump runs dry.
• If an accessory float switch or other liquid level control is installed, refer to manufacturer's
instructions. Failure to install control in compliance with national and local electrical and plumbing
codes and within manufacturer's recommendations may result in electrical shock or fire hazard,
unsatisfactory performance, or equipment failure.
The 9SC-CIM and 10SC-CIM manual pumps do not include an automatic liquid level control. The pump cord
for these pumps can be plugged directly into a properly grounded receptacle with voltage consistent with
the pump nameplate for continuous pump operation.
For automatic operation of a manual pump, a separate float switch or other liquid level control may be used.
If a float switch or level control has been added, refer to
testing operation.
