•	Check motor speed to be as specified in technical data for particular model.
•	Check air flow rate as per specification.
•	Check water flow rate as per specification.
•	Check Power current drawn by fan motor is within limits and as specified.
•	Check for abnormal noise or vibration during operation.
•	Check sprinkler rotates freely at 5 to 8 rpm or adjust holes to angle so as to achieve correct rpm.
•	Sprinkler Revolution Table (assumed at full flow).
•	Model DMB 2117 - DMB 4116 RPM 7 - 12 Model DMA 6616 - DMB 8416 RPM 5 - 8 Model DMA 1260 - DMD 1680 RPM 5 - 7 Model DME 1680 - DMB 1616 RPM 3.5 - 5
•	Ensure water is being distributed evenly over the FRP eliminator plates and there is no carry over from below the eliminator plate water must fall down below evenly, and not pass out.
•	Eliminator plate adjustment to be checked to ensure equal distance between fill top and plate bottom.
•	Measure Temperature at following locations:
•	i. water inlet. ii. water outlet / sump. iii. make up water inlet. iv. wet bulb / dry bulb temperature of air at inlet to tower at 4 locations equally spaced around tower. v. wet bulb / dry bulb temperature at outlet of tower above fan.
•	Adjust drain valve to give adequate blow down.
•	Set float to ensure proper operation and to avoid over flow when plant stops.
