OPERATION TESTING
Testing Manual Pump Operation
5. Verify the ON/OFF levels are within specification, and confirm that no potential obstructions exist
that could inhibit switch operation.
6. Confirm 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.
Confirm 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 ohm-
meter to check for continuity between the incoming
and outgoing connections of the piggyback plug
while raising and lowering the float.
Testing Manual Pump Operation
Risk of bodily injury, electric shock, or equipment damage.
• 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.
• 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.
The 12E-CIM pump does not include an automatic liquid level control. The pump cord for this pump can
be plugged directly into a properly grounded receptacle with voltage consistent with the pump name-
plate 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
page 5.
To test manual pump operation, follow these steps:
1. Connect a discharge hose to the pump's discharge port.
2. Place pump into a basin or test reservoir.
3. Direct the opposite end of the discharge hose back into the basin or test reservoir so that the water
discharged from the hose during testing will be contained within the basin or test reservoir. Secure
the hose to prevent the water pressure created during testing from causing the hose to exit the
basin or test reservoir.
4. If there is a valve on the discharge hose, be sure the valve is open.
5. Using a separate water source, fill the basin or test reservoir until the pump is fully submerged.
IMPORTANT: Do not attempt to run the pump without water; this could result in permanent dam-
age to the pump. Do not overfill the basin or test reservoir.
6. If the pump is provided with an attachment plug on the power cord, plug the pump's power cord
into a ground fault circuit interrupter (GFCI) receptacle with voltage consistent with the pump volt-
age, as indicated on the nameplate.
