Push ether start off if required.
(7)
Open the suction gage and discharge pressure gage shutoff valves to operate gages.
(8)
Depending on pumping conditions, pump may not start pumping immediately since the suction hose must
first fill with water. If the pump fails to pump after several minutes, check suction hose for leaks. A small
air leak will greatly reduce pumping efficiency under any conditions, and especially when operating under a
high suction lift.
(9)
After the pump starts pumping, as indicated by a reading on the discharge pressure gage, adjust the
throttle control to obtain desired pumping rate.
(10)
Check the pump for any unusual or excessive vibration. If excessive vibration is noticed, stop pump
immediately and correct the cause. Vibration usually results when pump or connecting lines are not
properly supported, aligned, or secured.
