If unit is mounted in an unheated area that is exposed to
temperatures below freezing, the unit and lines must be drained
to prevent damage to the pump.
Pump models have sealed permanently lubricated bearings and
require no additional lubrication.
Troubleshooting
No repair work shall be carried out during the warranty period
without prior factory approval. Liberty Pumps, Inc. assumes no
responsibility for damage or injury due to disassembly in the field.
Dismantling the pump voids the warranty. Servicing the pump
other than simple cleaning of pump inlet or impeller should be
referred to the factory or its authorized service centers.

1. Line circuit breaker may be off, tripped or loose. Have a
certified electrician check fuse or breaker.
