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 t he pump.
6. 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 from the pump skid and make certain that the
flapper seat is clean (see Figure 3 for valve location). Install and fill the pump again and repeat.
If after 20 minutes, the pump has not primed, refer to WP 0033, Troubleshooting.
CAUTION
Do not leave the pump running with V-107 closed without opening Vent Valve V-102.
Failure to observe this caution will cause the pump to overheat and damage the shaft seal.
7. If the MF Feed Tank reaches 3/4 full and you are not ready to continue with start-up, close raw
water flow control valve V-107 and stop Motor-Driven Raw Water Pump P-2.
