Do not position the pump float directly under the inlet from 

drain tile or in the direct path of any incoming water.

Any PRG-Series system discharge can be reduced to 1-1/4”.

Keep pump upright.

At no time should the pump be stored within an incomplete 

wet pit. The pump should not be placed into the pit until it 

can be fully operational.

Do not allow the pump to freeze.

Inspection and Storage

 Initial Inspection

The pump should be immediately inspected for damage that may 

have occurred in shipment.

1.

Visually check the pump and any spare parts for damage.

2.

Check for damaged electrical wires, especially where they exit 

the motor housing.

Contact Liberty Pumps customer service to report any damage or 

shortage of parts.

 Storage Before Use

 

Protect the power and control cords from the environment. 

Unprotected power and control (switch) cords can allow water 

to wick through ends into pump or switch housings, causing 

surroundings to become energized.

 

At no time shall the pump be stored within an incomplete wet 

pit. The pump shall not be placed into the pit until it can be 

fully operational.

Do not allow the pump to freeze.

Pumps are shipped from the factory ready for installation and use. 

Hold the pump in storage if the pump station is not complete.
If storage is necessary, the pump should remain in its shipping 

container. It should be stored in a warehouse or storage shed that 

has a clean, dry temperature-stable environment where the pump 

and its container are covered to protect it from water, dirt, 

vibration, etc. The cord ends must be protected against moisture.

Uninstalled

 pumps that are idle for greater than three months 

should have cutters and impellers manually rotated once a month 

to lubricate the seals.

Installed

 pumps that are idle for greater than one month should 

have cutters and impellers manually operated through the breaker 

panel once a month to lubricate the seals. 

For automatic models

turn off the breaker, unplug the piggyback switch, and plug the 

pump directly into receptacle. Turn the breaker on for 30 seconds, 

then turn the breaker off. Plug the piggyback switch back in. Refer 

to 

Piggyback Switch Operation

 on page 8.

Model Specifications

For complete listing of models and their specifications, refer to 

http://www.LibertyPumps.com/About/Engineering-Specs. Pump 

nameplate provides a record of specific pump information.

General Information

Before installation, read these instructions carefully. 

Each pump is individually factory tested to ensure 

proper performance. Closely following these 

instructions will eliminate potential operating 

problems, assuring years of trouble-free service.
PRG-Series pumps are to be used for handling 

septic tank effluent, sewage, and drain (storm) 

water.
Provide pump serial number in all correspondence.
Pumps are CSA certified to CSA and UL® 

standards.
Pumps must be serviced at a qualified repair facility 

approved by Liberty Pumps. No repair work should 

be carried out during the warranty period without 

prior factory approval. Any unauthorized field 

repairs void warranty. Contact Liberty Pumps at 

1-800-543-2550 to locate the closest authorized 

service center.

Operating Constraints

It is extremely important to verify that the pump 

has been sized correctly for the intended 

installation. The operating point of the pump must 

lie within the acceptable range as outlined by the 

applicable Liberty Pumps performance chart. 

Operating the pump outside of the recommended 

range can invalidate the CSA Certification of the 

pump and can also cause damage and premature 

failure. Operating outside of the recommended 

range can cause the pump to exceed its rated 

nameplate amp draw, which will void the pump 

certification. It can also cause motor overheating, 

cavitation, excessive vibration, clogging, and poor 

energy efficiency.
