Liberty Pumps XFL50 Serie Manuel D'installation page 2

1. General Information
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 provisions for proper grounding; to reduce the risk of electric shock, be certain that it is
properly connected to the control panel and that the panel is properly grounded.

Always wear rubber boots when water is on the floor and you must service the pump.

DO NOT bypass grounding wires.

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 panel 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 or breathing apparatus 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.

Electrical wiring and protection must be in accordance with the national electrical Code per NEC articles 500 through
503 for installations in Class I Division 1 Groups C and D environments, and any other applicable state and local
electrical requirements.
 DO NOT use pumps in water over 104F (40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.
 Float switches must be connected to an intrinsically safe circuit in the control panel. The installation of the float
switches is the responsibility of the installer – care should be taken to properly position them in the sump.
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).
Disconnect old pump from power source before handling.
