5. Before connecting to the motor, jog it to be sure it is running in the correct direction.
Refer to “General” on page 1.
6. Is the pressure relief valve installed properly?
7. Make sure suction piping is properly connected and sealed, and valves are open.
8. Make sure the discharge piping is properly connected and sealed, valves are open,
and there is a place for the liquid to go.
9. Make sure all guards are in place.
10. The above checklist is a general guideline to be used prior to starting the pump. Since
Viking Pump cannot foresee every application for our product and possible system
design, the final responsibility is with the user. The pump must be utilized within the
catalog specifications and the pump system must be designed to provide safe working
conditions.
The “start” button may now be pushed.
The pump should begin to deliver liquid within 15 seconds! If not, push the stop button. Do not
run the pump without liquid flow longer than 30 seconds or the pump may be ruined.
Review
Startup steps 1 through 10. Consider what the suction and discharge gauges may
indicate. If everything appears in order, re-prime pump. Refer to Mounting, page 2, item 8.
Push the “start” button. If nothing is flowing within 30 seconds, stop the pump. The pump is not
a compressor, it will not build up much air pressure. It may be necessary to vent discharge line
until liquid begins to flow.
If pump still does not deliver, consider one or more of the following:
1. The suction line has air leaks.
2. The end of the suction pipe is not submerged deeply enough in the liquid.
3. The suction lift is too great or the suction piping is too small.
4. Liquid is vaporizing in the suction line before it gets to the pump.
If after consideration of these points, the pump still does not deliver liquid, review all points
given under STArT uP and read through the TrOuBLESHOOTING guide and try again. If
pump still will not deliver liquid, contact your Viking Pump supplier.
