2. Lock out or disconnect the power

source to ensure that the pump will
remain inoperative.

3. Allow the pump to completely cool if

overheated.

4. Check the temperature before open

ing any covers, plates, or plugs.

5. Close the suction and discharge

valves.

6. Vent the pump slowly and cautiously.
7. Drain the pump.

TROUBLE
