Before Installation, read the following instructions carefully. Each Liberty pump is individually factory tested to assure
proper performance. By closely following these instructions, potential operating problems should be eliminated, providing
years of trouble-free service.
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.
Always wear rubber boots when water is on the floor and you must unplug the pump.
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, Uniform Plumbing Code, International
Plumbing Code, as well as all applicable local codes and ordinances.
Sump and sewage pumps often handle materials which could cause illness or disease. Wear adequate protective
clothing when working on a used pump or piping.
Never enter a pump basin after it has been used. Sewage and effluent can emit several gases which are poisonous.
Keep clear of suction and discharge openings. To prevent injury, never insert fingers into pump while it is plugged in.
DO NOT use this product for flammable or corrosive liquid.
DO NOT use this product in applications where human contact with the pumped fluid is common (such as swimming
pools, fountains, etc.)
NEVER dispose of materials such as paint thinner or other chemicals down drains, as they can chemically attack and
damage pump components, potentially causing product malfunction or failure.
DO NOT use pumps in water over 140
F (60
C).
DO NOT use pumps in mud, sand, cement, oil or chemicals.
DO NOT modify the pump in any way.
DO NOT lift or carry pump by power cord.
DO NOT remove any tags from pump or cords.
If pump is installed during construction before power is available, it must be protected from the environment to prevent
water from entering through the cord plug end, etc.
Disconnect old pump from power source before handling.
Separate the discharge pipe at either the check valve or at the union. If neither a check valve nor a union is part of the
existing discharge pipe, cut the pipe with a hacksaw and remove the pump (A union or check valve will need to be
installed at this cut).

Note: Manual models (“M” suffix) and 3 phase models, as designated above, require a separate approved pump control device or
panel for automatic operation. Operation of these models will be according to the control selected. Make sure the electrical
specifications of the control selected properly match the electrical specifications of the pump. 3 phase models require overload
elements selected or adjusted in accordance with the control or panel instructions.
Automatic pumps have a float switch preassembled. The optional (V) denotes that the pump is available with a vertical float.
