3. Maintenance and Troubleshooting

Troubleshooting:
Many common operation issues are outlined in the troubleshooting matrix at the end of this section. Use this resource
to diagnose and solve common problems which may occur with the pump or system. If problems persist, please
contact your Liberty Pumps authorized representative.
Maintenance:
The pump must be serviced at a qualified hazardous motor enclosure repair facility approved by Liberty Pumps. Any
unauthorized field repairs voids warranty and hazardous location ratings. Contact Liberty Pumps at 1-800-543-2550 to
locate the closest repair facility.
The pump must be pulled from the sump; prior to any service - disengage electrical power to the pump prior to
performing any work.
In the event the pump becomes clogged, the inlet screen can be removed to gain access to the pump's impeller. Once
the obstruction is removed the anti air lock hole should be cleaned.
The lower shaft seal is field serviceable; a certified repair shop should perform this task because they have the
capability to clean and flush the mid oil chamber.
This is the only work or maintenance that can be performed. All other maintenance or service such as cord
replacement requires a certified repair shop. Contact Liberty Pumps at 1-800-543-2550 to locate the closest authorized
hazardous duty motor repair shop.
*NOTE: Liberty Pumps, Inc. assumes no responsibility for damage or injury due to disassembly in the field.
Disassembly, other than at Liberty Pumps or its authorized service centers, automatically voids warranty.
Power cord and control cord replacement:
The power cord and control cord are not field replaceable. If either cord is compromised the entire pump must be
brought to a qualified hazardous motor enclosure repair facility approved by Liberty Pumps. Any unauthorized field
repairs voids warranty and hazardous location ratings. Contact Liberty Pumps at 1-800-543-2550 to locate the closest
repair facility.
