Safety Precautions

RISK OF ELECTRIC SHOCK
WARNING
 Always disconnect the pump from power source before
attempting to service the pump. Fatal electrical shock
could occur.
 The pump shall be plugged into a properly fused
electrical outlet with a ground fault circuit interrupter
(GFCI) that conforms to current National Electric Code
(NEC) and all applicable local codes. All wiring must be
performed by qualified personnel.
 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 pump with wet hands, when
standing on a wet/damp surface, or in water. Fatal
electrical shock could occur.
 Do not lift or carry the pump by its power cord. This will
damage the power cord, and could expose the
electrically live wires inside the power cord.
 Do not submerge motor or allow motor to be exposed to
water. Pump is intended for dry locations only. Serious
injury or death could result.
 This pump has been fitted with a 20 ft power cord. To
avoid the risk of electric shock, do not use an extension
cord unless absolutely necessary. Follow the Extension
Cord Length Table for proper gauge of a 3-wire,
grounding type extension cord.
RISK OF FIRE
WARNING
 Do not use to pump flammable or explosive fluids such
as gasoline, fuel oil, kerosene, etc. Do not use in
flammable and/or explosive atmosphere. Sparks could
ignite flammable liquids.
WARNING
RISK OF SERIOUS INJURY OR DEATH
 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.
 Do not allow children to play with the pump.
 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.
 Secure the discharge line before starting the pump. An
unsecured discharge line under pressure may whip.
Serious injury or death could result.
 Disconnect power, drain all liquids, and release all
pressure within the system before servicing any
component.

General Information

This manual contains valuable information on the use of the
Liberty Pumps Model 331 Transfer Pump. This information is
provided for safety and to prevent equipment problems.
Before use, read the following instructions carefully. Each pump is
individually factory tested to ensure proper performance. Closely
following these instructions will eliminate potential operating
problems, providing years of trouble-free service.
This portable transfer pump is designed for such applications as
emptying water heaters, swimming pool covers, livestock tanks,
boats, etc. It can also be used for an intermittent pressure boost
for applications such as washing cars, cleaning driveways, etc.
When used for charging or servicing hydronic systems, the pump
must be flushed with clear water afterwards to prevent corrosion.
Periodically inspect the pump and system components, checking
for weak and/or worn hoses. Be sure all connections are secure.
Protect the electrical cord from sharp objects, hot surfaces, oil,
