OPERATION

Draining the Pump

OPERATION
Risk of severe injury or death by electrical shock, high temperatures,
or pressurized fluids.
• To reduce risk of electrical shock, disconnect power before working on or around the system.
• Do not continuously run pump against closed discharge. Release all system pressure before working on any com-
ponent.
Risk of damage to pump or other equipment.
• Do not let the unit run dry (without liquid). It is designed to be cooled by pumping fluid. The seal may be dam-
aged and the motor may fail if the pump is allowed to run dry.
1. Prime the pump.
• Remove priming plug.
• Pour water into the priming port.
• Fill the pump and suction line with water.
• Rotate motor shaft to let air in casing escape.
• Refill at the priming port and replace priming plug.
2. If installing a 3-phase motor, check pump rotation by turning on power for a second.
• The impeller must rotate in a counterclockwise direction while facing the pump from the front of
the casing.
• If direction is wrong, interchange any two of three wires either at the motor or starter.
3. Start the pump.
4. 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.
5. Once the pump is fully functioning, completely open the discharge valve and a system outlet.

MAINTENANCE

Risk of severe injury or death by electrical shock.
• To reduce risk of electrical shock, disconnect power before working on or around the system.
• 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
Drain all piping and water tanks exposed to freezing conditions.
1. Remove the pipe plug from bottom of pump case.
2. Allow the water to drain.
3. Install the pipe plug to the pump case.
