Each unit is individually factory tested to ensure proper adjustment and operation. If the unit fails to operate properly, carefully re-read
the instructions and check that they have been followed correctly. Routine maintenance is not required on the pump itself, but
associated connections may require occasional attention. Lint and other foreign objects should be removed from the basin periodically.
 NOTE: Liberty Pumps, Inc. assumes no responsibility for damage or injury due to disassembly beyond float removal in the field.
Disassembly, other than at Liberty Pumps or its authorized service centers, automatically voids warranty.
