SETUP
Before Starting
1.Read safety instructions at beginning of manual.
2.Place pump as near to water as possible, on a firm flat, level surface.
3.To prime pump, remove fill cap (Figure 4) and fill pump case with water. If the pump case is not filled with water before starting, it will not begin pumping.
Pump casing must be filled with water before using pump, otherwise pump will not be able to begin pumping.
4.Check for leaks between pump and engine. If water is leaking between the pump and bearing housing, the seal inside the pump may be worn or damaged. Continued operation of the pump is not recommended. Further usage of the pump under these conditions may cause severe water damage to bearing housing assembly.
Hoses, Clamps and Strainer
1.Check that all hoses are securely attached to the pump. Make certain suction hose (Figure 4) does not have any air leakage. Tighten hose clamps and couplings as required.
2.It is recommended that 2 clamps be used when securing the suction hose to the inlet side of the pump.
3.Remember suction hoses must be rigid enough not to collapse when the pump is in operation.
4.Check that the discharge hose (Figure 4) is not restricted. Place hose so that it lays as straight as it is possible on the ground. Remove any twists or sharp bends from hose which may block the flow of water.
5.Make sure the suction strainer (Figure 4) is clean and securely attached to the water end of the suction hose. The strainer is designed to protect the pump by preventing large objects from being pulled into the pump. Failure to use a strainer could cause damage to the pump, impeller, pump shaft, pump bearings, or wear plate.
6.Shorter suction lift and suction hose length will produce better performance.
7.The discharge hose is usually a collapsible (thin- walled) hose, however if a
DANGER — High Pressure
PVC discharge hoses and
8.Pipes, hoses, fittings and elbows all produce friction that can significantly reduce the flow of water. Keep hose length to a minimum and minimize the use of elbows and other fittings to reduce friction.
9.Always use a suction hose or pipe that matches the size of the pump inlet to insure optimum performance and reduce the risk of damage to the pump.
10.It is recommended that the discharge hose or pipe match the size of the pump outlet to reduce friction as much as possible. Using a discharge line that is larger than the pump outlet will reduce friction and improve water flow. Similarly, a smaller line will reduce water flow by increasing friction.
CAUTION — Strainer Placement
The strainer should be positioned so it will remain completely under water. Running the pump with the strainer above water for long periods can damage the pump.
CAUTION — Equipment Damage Hazards
DO NOT pump flammable fluids, corrosive chemicals or fluids containing toxic substances. These fluids can create potentially dangerous health and environmental hazards. Contact local authorities for assistance.
