Free air discharge capacity
If the temperature of the air differs from 15 °C, the discharge capacity from the graph can be corrected by multiplying it by the following equation: 289 273 + T (T is the actual temperature in °C) It may be assumed that the temperature of the air is the same as the temperature of the water.

Safety information, installation and maintenance For full details see the Installation and Maintenance Instructions (IM-P149-13) supplied with the product. Installation note: The ¾" AE10S high capacity automatic air vent must always be fitted with the inlet at the bottom so that the float mechanism is rising and falling in a vertical plane. From the tapping provided at the low point of the cover, a ½" balance pipe having continuous rise towards the automatic air vent must be fitted and connected into the inlet pipework (as shown in the sketch) which is essential for satisfactory operation. Because of the way automatic air and gas vents operate they all dribble water and liquid when discharging air and gas. This is perfectly normal. Spirax Sarco recommend piping the discharge to a safe visible point or drain via an air break. Maintenance note: With suitable isolation, repairs can be carried out with the automatic air vent in line. Disposal The product is recyclable. No ecological hazard is anticipated with disposal of this product, providing due care is taken.
