NOTE
The time required to prime the pump will depend on the elevation of the pump (suction lift)
and on the length of hose out of the water. The listing below provides typical times to be
expected with 30 feet of hose out of water.
Suction Lift (Ft)
Priming Time (Minutes)
5
3 to 5
10
5 to 10
15
10 to 15
20
15 to 20
CAUTION
Potential for overheating. While the pump is evacuating air from the suction hose, the
priming water circulates in the pump. After a period of time, the water and pump may get
hot. Check the pump regularly with your hand for heating. If the pump starts getting hot,
remove the vent hose, add more water to the pump, then reinstall the vent hose. Repeat
as needed to keep the pump cool until it begins pumping water. Failure to observe this
caution may result in overheating and damage to the pump.
10. If the expected time for priming is exceeded, stop the pump and check all of the hose couplings
that are out of the water. Specifically check the gaskets to be certain that they are free of sand
and dirt. Remove Check Valve Adaptor A-01 (see Figure 4) from the pump skid and make certain
that the flapper seat is clean. Install and fill the pump again and repeat. If after 20 minutes, the
pump has not primed, refer to WP 0033, Troubleshooting.
11. When using both pumps, start the Motor-Driven Pump P-2 after the discharge hose from P-1
pump is pressurized. Start the P-2 pump by pushing the Raw Water Pump #2 START button on
the OCP.
