INTRODUCTION

This instruction sheet provides you with the information required to safely own and operate your Little Giant pump. Retain these instructions for future reference.

The Little Giant pump you have purchased is of the highest quality workmanship and material, and has been engineered to give you long and reliable service. Little Giant pumps are carefully tested, inspected, and packaged to ensure safe delivery and operation.

Please examine your pump 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 PUMP. KNOW THE PUMP’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 around a chemical-resistant plastic separator housing. Inside this housing is a magnet fixed to the impeller. The impeller assembly is free to rotate on a spindle that is supported at both ends. The spindle is held captive and does not turn. Front and rear thrust washers are utilized as wear bearings. The washers are held captive and do not revolve. This prevents wear on the shaft. With the magnetic coupling the motor drives the impeller. This coupling eliminates the conventional shaft seal and its possibility of leakage.

PUMP MATERIALS

The pump's plastic parts are made of glass-filled polypropylene.

The spindle shaft and thrust washers are titanium. The impellerdriven magnet is uncoated Ceramagnet A (barium ferrite) type ceramic, and the static O-ring seal is Buna-N.

INSTALLATION

This Little Giant pump is completely pre-assembled and pretested at the factory, and is ready for immediate use. The pump may be installed in any position. It may be mounted vertically with the pump head down. Ensure that proper plumbing connections are made; see specifications table to determine what size intake and discharge your pump has. Use a thread sealer on all pipe connections and hand-tighten only. Make sure the wing nuts are tight before operating the pump. The motor nameplate lists all electrical data. Make sure the pump is connected to proper voltage before operating. When wiring pumps with no plug, the green (or green/yellow) wire is ground, and the other two are line (live).

Do not allow the models to run dry (without liquid). These pumps are not submersible; operate the pumps only in the in-line mode.

Do not put the units in liquid. Pump should be installed in a dry area and protected from splash. These pumps are not self priming; they must be installed so that the pump head (volute) is flooded when the pump is started. That is, the inlet of the pump must be below the level of the surface of the liquid being pumped (Figure 1).

CAUTION: To reduce the risk of electrical shock, remove the pump from power before attempting to service or remove any part.

Read all instructions and safety guide lines thoroughly. Failure to follow the guidelines and instructions could result in serious bodily in jury and/or property damage.

Do not pump flammable liquids such as gasoline or fuel oil.

Make sure pump is grounded.

During operation, the area surrounding the pump may be covered with water; take care when handling the pump.

Do not disconnect plumbing connections when pump is in operation.

Do not stand in water when changing fuses.

PUMP CONSTRUCTION

The patented Little Giant magnetic drive pump design consists of a cylindrical drive magnet attached to the motor shaft, which rotates

FIGURE 1

Do not restrict the intake side of the pump. Connections on the intake side should not be of smaller inside diameter pipe or tubing or hose than the intake inside diameter of the intake thread designation. If reduced flow is required restrict the discharge side.

Installing a valve or other type of restriction device on the discharge side is the proper method for reducing flow from the pump. When using a valve the pump can be throttled to provide various flow rates and pressures without harming the motor or the pump parts.
