During evaporative cooling water is pumped onto the cooling pads by cooling pumps. When the cooling
pumps first start operating care must be taken to control the amount of water added onto the cooling pads.
Too much water on the pads initially will cause the house temperature to reduce rapidly. This in turn will
cause fans to switch off (if automated), changing the wind chill effect on the birds, and the environmental
conditions from one end of the house to the other. Ultimately, this affects bird comfort and health.
