Installation (continued)
2.Mount the unit on a solid founda- tion. On fixed installation, install both a union and a gate valve (not furnished) on the discharge side of the pump for service convenience.
Do not use a globe or other restricting type of valve at the discharge, as this
would seriously restrict the capacity of the pump.
3.Attach suction line piping to the suc- tion inlet and discharge line piping to the discharge outlet. The suction line should be positioned such that there is a continual upward slope from the fluid source to the pump. Avoid using loops or sections of pipe or fittings which might permit air to become trapped.
IMPORTANT: If plastic or fabric hose is used for the suction piping, it should be of a reinforced type so as not to collapse under suction. The discharge piping should be at least the same size as the discharge connection. Suction piping should be the same size as the discharge piping or one size larger. Unless long horizontal runs are involved, discharge piping should not be larger than suction piping. Avoid using looped sections of pipe which might permit air to become entrapped. Assure

should not be greater than 25% of the suction inlet size for solid handling pumps and 50% of the suction inlet size for trash pumps.
Operation
1.Fill the engine crankcase with oil as specified in the engine manual. If the engine has no dipstick, then fill the crankcase with oil until the oil over- flows (starts spilling out of the crankcase). Periodically check oil level thereafter.
2.Fill the gasoline tank as required. Refer to engine instruction booklet.
Never add gasoline to a hot engine!
See General Safety Information for proper handling of gasoline.
3.Fill the pump with liquid through the pump discharge or the priming port supplied with these units. It may be convenient to screw in a service tee or a tee with a nipple into the dis- charge, so that the pump can be filled (using the upper leg of the tee) without disconnecting the discharge hose or pipe. The vertical leg must be closed with a pipe plug during pumping. Remember, the pump is
Do not run pump dry, as permanent
damage to the mechanical seal will result.
5.A suitable suction strainer should be attached to the suction line so that large pieces of foreign material are not drawn into the pump. The maxi- mum opening in the suction strainer
4.Start the engine, following instruc- tions in the engine manual.
5.With a suction lift of 5 to 10 feet, the pump should discharge liquid within
