USER MANUAL Automatic Hydroponic Utility Pump

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 power cord is equipped with stripped lead wires, such as on 230V models, be sure that the wires are connected to a power source correctly. The green/ yellow wire is the ground, and the blue (or white) and brown (or black) are live.
4. If any failure occurs in the power cord, contact any authorized personnel or the manufacturer.

CONSULT INSTRUCTION SHEET ILLUSTRATIONS FOR PROPER ASSEMBLY AND DISASSEMBLY OF YOUR PUMP.

OPERATION

1. Place pump on solid surface in water at least 3/4” deep to begin pumping. Pump should be totally submerged for proper cooling of the motor when pump is operated for extended periods.
2. Connect garden hose to hose adaptor or 1” diameter pipe directly into pump outlet.
3. Pump with screen will remove water to within 3/8”. Pump without screen (it will snap off by wedging a coin between the slots; see Figure 2) will remove water to within 1/8”.
4. If the surface is dirt or sand, place pump on flat surface such as a piece of wood or metal to prevent it from being clogged.
5. Do not let the unit run 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 unit is going to be idle for a period of time, follow the cleaning instructions outlined in the next section. Do not let the unit freeze in the wintertime. This may cause cracking or distortion that may destroy the unit.
7. When using 3/4” garden hose adaptor performance will be reduced approximately 15%. This pump does not deliver enough pressure to operate lawn sprinklers properly.
8. If fused-type plug is used on 230V units, a 5.0 amp fuse is recommended.
9. If using an aluminum body pump in an area with water having a high mineral content (hard water) or if other metals (copper tubing, metal fountain heads, etc.) are present in the pond or fountain, a condition called “galvanic corrosion” may occur. The recommended solution to this situation is the use of a sacrificial anode attached to the pump. This anode works on the same principle as the anode found in hot water heaters and boat motors. Contact your local distributor and ask for the model SA-1 by Little Giant.

MAINTENANCE

DISCONNECT THE PUMP FROM THE POWER SOURCE BEFORE SERVICING OR REMOVING ANY COMPONENT!

1. The motor housing of the pump is completely sealed and requires no service. Disassembly of the motor housing or alteration of the power cord voids all warranty. The power cord on these units cannot be replaced. In case of damage the whole unit must be replaced.
2. The motor is a continuous duty type sealed in oil with an automatic thermal overload protector device.
3. The pump can run against a restricted discharge such as a fountain without damage to the pump.
4. If the pump becomes clogged snap the screen off and clean out the area.
5. If necessary remove the 6 screws holding the volute base to the motor housing and clean the volute.
6. If the impeller is removed, make sure that a spacing of .050” (1.27 mm) with shaft pushed toward housing is maintained when reassembling (Figure 1).
7. When reassembling, remember to install the seal ring between the volute base and the motor housing.

SAFETY GUIDELINES

1. Ensure that unit is disconnected from power source before attempting to service or remove any component.
2. 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.
3. Do not handle pump with wet hands or when standing on a wet or damp surface or in water.
4. 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.
5. 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.
6. 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.
7. If pump is an oil-filled pump, 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.
