Basic Operation Manual
12
NOTICE: Please see to “Starting” before proceeding any further. Operation of open systems with the liquid
level below the top of the pump:
NOTICE: The suction pipe requires a check valve or isolation valve.
1. Close to discharge isolation valve.
2. Remove the vented priming plug.
3. Pour liquid through the priming port until the suction pipe and the pump are completely filled with liquid.
4. Replace the vented priming plug and tighten it securely.
5. Repeat steps 1 - 4 until the pump is primed.
NOTICE: Please see “Starting” before proceeding any further.
CHECKING DIRECTION OF ROTATION
NOTICE: Do not disconnect the motor from the shaft to check the direction of rotation. If you remove the coupling,
then you must adjust the shaft position when you reinstall it. This must be done before starting the pump.
Arrows on the pump head show the correct direction of rotation. When seen from the motor fan, the pump should
rotate counterclockwise
. For pump motors without a fan, remove one of the coupling guards and look at the
coupling to determine the direction of rotation. Turn off the pump and replace coupling guard.
NOTICE: Do not check the directions of rotation until the pump has been filled with liquid. See “Priming” above.
1. Switch power off.
2. Remove the coupling guard and rotate the pump shaft to be certain it can turn freely. Replace the coupling
guard.
3. Verify that the electrical connections are in accordance with the wiring diagram on the motor.
4. If the fan is visible, turn on and off to verify rotation.
5. To reverse the direction of rotation, first switch OFF the power supply.
6. On three phase motors, switch 2 of the 3 power leads on the load side of the starter. On single phase motors,
see the connection diagram on the motor nameplate. Change the wiring as indicated.
WARNING! Risk of electric shock.
Can shock, burn or kill. Ground the pump motor correctly before connecting to power supply per article
250-80 of National Electric Code (NEC) in the U.S., or the Canadian Electrical Code (CEC), as applicable.
7. Switch the power supply and recheck the direction of motor rotation.
STARTING
1. If a suction line isolation valve has been installed, check to be sure that it is completely opened.
2. For initial starting, the isolation valve in the discharge pipe should be almost closed.
3. Start the pump.
4. When the piping system has been filled with liquid, slowly open the discharge isolation until it is completely open.
Opening the valve too fast may result in water hammer in the discharge pipe. If the pump or system starts to
rattle, the pump is cavitating; to avoid damage to the pump, reduce the flow through the discharge isolation
valve until the rattling stops. If this does not give adequate flow for your installation, call your installer or
system designer.
5. Record the voltage and amperage of the motor. Adjust the motor overloads if required
6. If pressure gauges have been installed, check and record operating pressures.
7. Check all controls for proper operation.
