Safety Guidelines
Safety Precautions
Accidental contact with electrically live parts, items, fluid, or
water can cause serious injury or death.
Always disconnect pump(s) from power source(s) before
handling or making any adjustments to either the pump(s),
the pump system, or the control panel.
All installation and maintenance of pumps, controls,
protection devices, and general wiring shall be done by
qualified personnel.
Do not remove cord and strain relief, and do not connect
conduit to pump.
All electrical and safety practices shall be in accordance with
the National Electrical Code®, the Occupational Safety and
Health Administration, or applicable local codes and
ordinances.
Pump shall be properly grounded using its supplied
grounding conductor. Do not bypass grounding wires or
remove ground prong from attachment plugs. Failure to
properly ground the pump system can cause all metal
portions of the pump and its surroundings to become
energized.
Do not handle or unplug the pump with wet hands, when
standing on damp surface, or in water unless wearing
Personal Protective Equipment.
Always wear dielectric rubber boots and other applicable
Personal Protective Equipment (PPE) when water is on the
floor and an energized pump system must be serviced, as
submerged electrical connections can energize the water. Do
not enter the water if the water level is higher than the PPE
protection or if the PPE is not watertight.
Do not lift or carry a pump or a float assembly by its power
cord. This will damage the power cord, and could expose the
electrically live wires inside the power cord.
The electrical power supply shall be located within the length
limitations of the pump power cord, and for below grade
installations it shall be at least 4 ft (1.22 m) above floor level.
Do not use this product in applications where human contact
with the pumped fluid is common (such as swimming pools,
fountains, marine areas, etc.).
Protect the power and control cords from the environment.
Unprotectedpowerandcontrol(switch) cords can allow water
to wick through ends into pump or switch housings, causing
surroundings to become energized.
Do not use an extension cord to power the product. Extension
cords can overload both the product and extension cord
supply wires. Overloaded wires will get very hot and can catch
on fire.
This product requires a separate, properly fused and
grounded branch circuit, sized for the voltage and amperage
requirements of the pump, as noted on the nameplate.
Overloaded branch circuit wires will get very hot and can
catch on fire. When used, electrical outlets shall be simplex of
the appropriate rating.
Do not use this product with or near flammable or explosive
fluids such as gasoline, fuel oil, kerosene, etc. If rotating
elements inside pump strike any foreign object, sparks may
occur. Sparks could ignite flammable liquids.
These pumps are not to be installed in locations classified as
hazardous in accordance with the National Electric Code®,
ANSI/NFPA 70.
Do not modify the pump/pump system in any way.
Modifications may affect seals, change the electrical loading
of the pump, or damage the pump and its components.

All pump/pump system installations shall be in compliance
with all applicable Federal, State, and Local codes and
ordinances.
Do not allow children to play with the pump system.
Do not allow any person who is unqualified to have contact
with this pump system. Any person who is unaware of the
dangers of this pump system, or has not read this manual, can
easily be injured by the pump system.
Wear adequate Personal Protective Equipment when working
on pumps or piping that have been exposed to wastewater.
Sump and sewage pumps often handle materials that can
transmit illness or disease upon contact with skin and other
tissues.
Do not remove any tags or labels from the pump or its cord.
Keep clear of suction and discharge openings. To prevent
injury, never insert fingers into pump while it is connected to
a power source.
Do not use this product with flammable, explosive, or
corrosive fluids. Do not use in a flammable and/or explosive
atmosphere as serious injury or death could result.
This product contains chemicals known to the State of
California to cause cancer and birth defects or other
reproductive harm. www.p65warnings.ca.gov.
Do not dispose of materials such as paint thinner or other
chemicals down drains. Doing so could chemically attack and
damage pump system components and cause product
malfunction or failure.
Do not use these pumps with fluid over 140°F (60°C).
Operating the pump in fluid above this temperature can
overheat the pump, resulting in pump failure.
Do not use pump system with mud, sand, cement,
hydrocarbons, grease, or chemicals. Pump and system
components can be damaged from these items causing
product malfunction or failure. Additionally, flooding can
occur if these items jam the impeller or piping.
Submersible Pump—do not run dry.
Introduction
The pump is supplied with its own separate manual. Ensure
receipt of this manual, and that it is read and understood prior to
installing and using this system. Familiarity with the pump is
critical.
This manual provides a brief overview of the system and deals
mainly with installation of the system. It does not cover the
specifics of the pump. For questions, call Liberty Pumps customer
service at 800-543-2550.
Application
The CSP-Series kit is 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.
Performance Curve
Installation
All installation and maintenance of pumps, controls,
protection devices, and general wiring shall be done by
qualified personnel.
All electrical and safety practices shall be in accordance with
the National Electrical Code®, the Occupational Safety and
Health Administration, or applicable local codes and
ordinances.
Backfill
For in-ground installation, a hole should be excavated as small as
possible, leaving at least 8” of diametrical clearance. Coarse gravel
is recommended for backfill.
Inlet Line
The CSP-Series kit includes a perforated basin for gathering water.
Additional inlets may be added with a hole saw for allowing drain
lines or weep tiles.
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-Series kit includes 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.

Check Valve
The CSP-Series kit includes a threaded check valve for use with the
discharge hose. This prevents 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.
Power Cord
The pump power cord is equipped with a grounding conductor
and grounding-type 3-prong plug. It shall be connected to a
separately fused, grounded, 3-wire grounding-type receptacle of
15 Amp capacity with the proper 115 V. Verify all electrical wiring
and connections are in accordance with the National Electric
Code® and all applicable local codes.
