INTRODUCTION
This instruction sheet provides you with the information required to safely own and
operate your product. Retain these instructions for future reference.
The product you have purchased is of the highest quality workmanship and
material, and has been engineered to give you long and reliable service. These
products are carefully tested, inspected, and packaged to ensure safe delivery
and operation. Please examine your item(s) carefully to ensure that no damage
occurred during shipment. If damage has occurred, please contact the place of
purchase. They will assist you in replacement or repair, if required.
READ THESE INSTRUCTIONS CAREFULLY BEFORE ATTEMPTING TO
INSTALL, OPERATE, OR SERVICE YOUR LITTLE GIANT PRODUCT. KNOW
THE PRODUCT’S APPLICATION, LIMITATIONS, AND POTENTIAL HAZARDS.
PROTECT YOURSELF AND OTHERS BY OBSERVING ALL SAFETY
INFORMATION. FAILURE TO COMPLY WITH THESE INSTRUCTIONS COULD
RESULT IN PERSONAL INJURY AND/OR PROPERTY DAMAGE!
SAFETY GUIDELINES
Disconnected the pump from the power source before servicing or removing any
component.
Do not use to pump flammable or explosive fluids such as gasoline, fuel oil,
kerosene, etc. Do not use in explosive atmospheres. Pump should only be used
with liquids compatible with pump component materials.
Do not handle pump with wet hands or when standing on a wet or damp surface
or in water.
This pump is supplied with a grounding conductor and/or grounding type
attachment plug. To reduce the risk of electric shock, be certain that it is
connected to a properly grounded grounding type receptacle.
In any installation where property damage and/or personal injury might result from
an inoperative or leaking pump due to power outages, discharge line blockage,
or any other reason, a backup system(s) and/or alarm should be used.
Support pump and piping when assembling and when installed. Failure to do so
may cause piping to break, pump to fall, motor bearing failures, etc.
If pump is oil-filled, the motor housing is filled with a dielectric lubricant at the
factory for optimum motor heat transfer and lifetime lubrication of the bearings.
Use of any other lubricant could cause damage and void the warranty. This
lubricant is non-toxic; however, if it escapes the motor housing, it should be
removed from the surface quickly by placing newspapers or other absorbent
material on the water surface to soak it up, so aquatic life is undisturbed.
This pump has been tested using water only. The suitability of this pump for use
with liquids other than water is the responsibility of the end-user.
This pump is not intended for permanent mounting to a building structure by
bolting or similar means.
ELECTRICAL CONNECTIONS
1. Check the pump label for proper voltage required. Do not connect to voltage
other than that shown.
2. If pump is supplied with a 3-prong electrical plug, the third prong is to ground
the pump to prevent possible electrical shock hazard. DO NOT REMOVE the
third prong from the plug. A separate branch circuit is recommended. Do not
use an extension cord. Do not cut plug from the cord. If the plug is cut or the
cord is shortened, then this action will void the warranty.
3. If the cord is equipped with stripped lead wires, such as on 230v models,
be sure that the lead wires are connected to a power source correctly. The
green/yellow wire is the ground, and the blue (or white) and the brown (or
black) are live.
4. All wiring should be performed by a qualified electrician.
5. DO NOT use sheet metal screws to secure the equipment grounding
conductor.
CONSULT INSTRUCTION SHEET ILLUSTRATIONS FOR PROPER ASSEMBLY
AND DISASSEMBLY OF YOUR PUMP.
OPERATION
1. This pump is designed to operate submerged or in-line. It can be placed in
any position, but preferably the volute should be located to the side.
1
2. If the surface is dirt or sand, place pump on a flat surface such as a piece of
wood or metal to prevent it from being clogged.
3. The weight of the pump must be supported adequately. DO NOT support the
pump by the intake or discharge connections alone.
4. Do not attempt to restrict the intake side of these pumps. Restricting the
intake may cause damage to the seal and may starve the pump. If you
require reduced flow rates, then place a valve on the discharge side of the
pump or if flexible vinyl tubing is used, a clamp can be used on the tubing to
restrict the flow.
5. Do not let the pump operate dry. It is designed to be cooled by pumping
fluid. You may damage the seal and the motor may fail if the pump is allowed
to run dry.
6. If the pump is going to be idle for an extended period, follow the cleaning
instructions outlined in the next section. Do not let the pump freeze in the
wintertime. This may cause cracking or distortion that may destroy the
pump.
7. If fused type plug is used on 230V units, a 2.0 amp fuse is recommended.
MAINTENANCE
DISCONNECT THE PUMP FROM THE POWER SOURCE BEFORE SERVICING
OR REMOVING ANY COMPONENT!
1. This pump is permanently lubricated. Oiling is not required. DO NOT open
the sealed portion of the pump or remove housing screws. The power cord
cannot be replaced. In case of damage the entire pump must be replaced.
2. Periodic cleaning of the pump parts will prolong the life and efficiency of the
pump. Refer to the assembly and disassembly of the pumping head.
3. First remove the intake screen from the pump. Then remove the volute
mounting screws. (DO NOT remove any other screws.)
4. Lightly clean any corrosion or debris which may clog the impeller. Use a
brush and penetrating oil and lightly scrape to remove encrusted material.
5. Turn the impeller by hand to make sure it turns freely. Set pump down so
the pump and impeller are not touching anything. Plug the unit into GFCI
circuit for 10 seconds to see if the impeller turns; a) If it is rotating and GFCI
did not trip, unplug unit and install parts in reverse order in which they were
removed. b) If it does not rotate, if pump is tripping circuit breakers, or not
operating properly after cleaning, return to Proven Pump or its authorized
service center. DO NOT attempt repairs yourself.
6. Be certain power cord is in good condition and contains no nicks or cuts.
7. The motor is a continuous-duty type, sealed in oil with an automatic thermal
overload protector device.
WARNING: THE PUMP MOTOR IS EQUIPPED WITH AN
AUTOMATIC RESETTING THERMAL PROTECTOR AND MAY RESTART
UNEXPECTEDLY. PROTECTOR TRIPPING IS AN INDICATION OF
MOTOR OVERLOADING AS A RESULT OF OPERATING THE PUMP
AT LOW HEADS (LOW DISCHARGE RESTRICTION), EXCESSIVELY
HIGH OR LOW VOLTAGE, INADEQUATE WIRING, INCORRECT MOTOR
CONNECTIONS, OR A DEFECTIVE MOTOR OR PUMP.
8. The pump can run against a restricted discharge such as a fountain without
damage to the pump.
