3.1 Pump Driving

In order to make the circulating water fill every part of the circulation system, revolve the circulation pump for a short while, to drain the air out of the piping of the circulating water.

Before entering steady operation, confirm again that the water basin is filled to the specified level, and then start the pump.

Gradually open the adjusting valve and adjust it so that the water will reach the volume specified on the name plate of the cooling tower.When circulation of water becomes steady, check to see if the sprinkler is revolving smoothly and properly.

3.2 Fan Driving

Clean up the surroundings of the tower and make sure that no foreign matter is near the air inlet and outlet.

When the equipment goes into steady operation, measure phase voltages and phase currents to see if the motor is operating at the rated current range indicated on the name plate.
