5. Gradually open the discharge valve to the halfway point.
• If the pump does not deliver water within seconds, stop the motor and prime pump again.
• Several starting attempts may be necessary to expel all air from the pump and suction lines.
6. Once the pump is fully functioning, completely open the discharge valve and a system outlet.
MAINTENANCE
• Check the pump periodically for loose or rubbing parts.
• Service immediately if any unusual noise, leaks, or vibrations develop.
• Drain the pump should it be subjected to freezing temperatures.
Draining the Pump
All piping and water tanks exposed to freezing conditions must be drained.
For 5-25 GPM pumps:
1. Disconnect the suction line at a connection close to the pump casing and allow the water to drain.
2. Replace the suction line, carefully cleaning the threads and applying fresh thread compound.
For 35 & 45 GPM pumps:
1. Remove the drain plugs and drain the pump casing.
2. Carefully clean the threads and apply thread sealant.
3. Replace the drain plugs.
