Frequently Asked Questions - CSP-257 Liberty Pumps

How to install the CSP-257 pump?

Dig a hole at least 8 inches (20.32 cm) in diameter. Place the pump in a perforated basin. Fill the hole with medium gravel. Connect the provided discharge hose (24 ft) using the 1 1/2 in x 1 1/4 in fitting. Ensure the float moves freely. Plug the pump into a 115 V grounded outlet.

What is the required electrical voltage for the CSP-257?

The pump requires a 115 V (nominal voltage), 60 Hz power supply, with a dedicated 15 amp branch circuit and grounding.

Can I use an extension cord with the Liberty Pumps CSP-257 pump?

No, the use of an extension cord is prohibited. The pump must be plugged directly into a properly grounded outlet within reach of the power cord.

How to clean the pump float?

First, unplug the pump. Remove the float and clean it with clean water to remove any buildup. Ensure it moves freely without obstruction.

What to do if the pump does not turn on?

First, check the fuse or circuit breaker. Make sure the outlet works. If the float is stuck, clean it. If the problem persists, an electrician must check the wiring.

What to do if the pump runs but does not pump water?

Check the discharge pipe for blockages (including ice). Make sure the check valve is not stuck in the closed position. If the maximum discharge height (23 ft) is exceeded, reduce the height. If the impeller is blocked, disassemble and remove foreign objects.

How to check the check valve?

Unplug the pump. Remove the check valve and check that it opens and closes freely. Clean it if necessary. Reinstall it correctly.

What is the warranty of the CSP-257 pump?

Liberty Pumps offers a 3-year limited warranty from the date of purchase, covering defects in material and workmanship. It does not cover damage due to incorrect installation, misuse, or modifications.

Can I use the pump to pump hot water?

No, using the pump in water hotter than the intended temperature (not specified but generally cold water) voids the warranty. It is designed for clean, cold water.

How to protect the pump from freezing?

Install the pump below the frost line or indoors. If a check valve is installed, the discharge pipe must be at a sufficient depth to prevent freezing. In winter, make sure water does not freeze in the pump.

1. General Information and Safety Guidelines

Before installation, read the following instructions carefully. Each Liberty pump is individually factory tested to insure proper performance. Closely following these instructions will eliminate potential operating problems, assuring years of trouble-free service.

WARNING

• Risk of electric shock. Always disconnect the pump from the power source before handling or making adjustments.
• The electrical connections and wiring for a pump installation should only be made by qualified personnel.
• This pump is supplied with a grounding conductor and grounding-type attachment plug. To reduce the risk of electric shock, be certain that it is connected only to a properly grounded, grounding-type receptacle.
• Do not bypass grounding wires or remove ground prong from attachment plugs.
• Do not use an extension cord.
• This pump requires a separate, properly fused and grounded branch circuit. Make sure the power source is properly sized for the voltage and amperage requirements of the pump, as noted on the nameplate.
• The electrical outlet shall be within the length limitations of the pump power cord, and at least 4 feet above floor level to minimize possible hazards from flood conditions.
• The installation must be in accordance with the National Electric Code and Plumbing Codes as well as all applicable local codes and ordinances.

2. Installation

Fig. 1 – Typical Residential Installation This is a recommended installation only.

CRAWL SPACE DISCHARGE BACKFILL DRAIN LINE OR WEEP TILE (OPTIONAL) GROUND LEVEL FROST LINE FOUNDATION

Figure 1

Application: The CSP-237, CSP-257, and CSP-457 crawl space pumps are designed for use in a crawl space or where pooling water is occurring. Allowing the water in the pump or discharge line to freeze may cause damage to the pump. In colder regions, the pump should only be installed indoors or deep enough to be below the frost line.

A. BACKFILL: For in ground installation a hole should excavated as small as possible, leaving at least 8" of diametrical clearance. Course gravel is recommended for backfill.
B. INLET: The CSP-237, CSP-257, and CSP-457 include a perforated basin for gathering water. Additional inlets may be added with a hole saw for allowing drain lines or weep tiles.
C. DISCHARGE: When attaching the discharge, place the pump in the basin being careful to keep float from any obstruction or from hitting the tank wall. The CSP-237, CSP-257, and CSP-457 include a DHK-24 discharge hose kit. A 1-1/2" X 1-1/4" hose adapter will thread into the pump discharge. The 24' flexible hose will fit over the barbed fitting of the adapter and should be tightened down with a hose clamp. The hose will fit through the grommet in the basin cover and can be cut to the required length. Exit the discharge of water in an area that will drain away from the building and foundation.
D. CHECK VALVE: The CSP-237, CSP-257, and CSP-457 include a threaded check valve for use with the discharge hose. If the pump is short cycling, then a check valve may be required. This would prevent water from draining back through the discharge hose into the basin. When using a check valve, the discharge line must be protected from freezing by running the discharge deep enough below ground level to be beneath the frost line. See figure 1.
E. POWER CORD: The pump power cord is equipped with a grounding conductor and grounding-type 3-prong plug. It should be connected to a separately fused, grounded, 3-wire grounding-type receptacle of 15-amp capacity with the proper 115V. Make sure all electrical wiring and connections are in accordance with the National Electric Code and all applicable local codes.

WARNING

• Risk of electric shock. Always disconnect the pump from the power source before handling or making adjustments.
  • DO NOT remove the plug or ground prong.
  • DO NOT use an extension cord.

3. Maintenance and Troubleshooting

Each unit is individually factory tested to ensure proper adjustment and operation. If the unit fails to operate properly, carefully re-read the instructions to see that they have been followed correctly. Routine maintenance is not required on the pump itself, but associated connections may require occasional attention. The check valve on the discharge should also be checked for freedom of operation at the same time.

*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.

Problem	Cause	Correction
Pump will not turn on	·Blown fuse or other interruption of power; improper voltage.	·Check that the unit is securely plugged in. Have an electrician check all wiring for proper connections and adequate capacity.
	·Defective switch or build-up on tank wall restricting free movement of float switch.	·Check that float is free to move. If build-up restricts float, clean and reinstall. If defective, replace switch.
Pump runs or hums but does not pump.	·Discharge is blocked or restricted.	·Check the discharge line for blockage, including ice if the line passes through or into cold areas.
	·Check valve is stuck closed or installed wrong.	·Remove and examine for freedom of operation and proper installation.
	·Total lift height has been reached (see Fig. 2)	·Try routing pipe to a lower level. If not possible, another pumping station may be required at a level of roughly half the total lift.
	·Pump impeller is jammed.	·*Disassemble the receiver and bottom base of pump. Remove foreign material. Reassemble.
	·Defective switch.	·Check that float is free to move. If build-up restricts float, clean and reinstall. If defective, replace switch.
Pump does not turn off	·Defective switch or build-up on tank wall restricting free movement of float switch.	·Check that float is free to move. If build-up restricts float, clean and reinstall. If defective, replace switch.
Pump operates noisily.	·Foreign objects in impeller cavity.	·*Disassemble the receiver and bottom base of pump. Remove foreign material. Reassemble.
	·Broken impeller	·Consult the factory for information regarding the replacement of impeller.
