Differential presure bar (x 100 kPa)

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 equal to the

temperature of the water.

Safety information, installation and maintenance

For full details see the Installation and Maintenance Instructions

(IM-P017-11) supplied with the product.

Installation note:

The AE50S should be installed vertically with the inlet at the bottom.

We recommend piping the discharge to a safe visible point or drain

via an air break.

Installation in superheated water:

For superheated water applications we recommend that 1 m to

2 m of 3⁄4" vertical pipeline be fitted prior to the inlet of the vent.

On superheated water systems the outlet pipework must be sized

to accomodate any flash steam created during discharge.

Direct the outlet pipework to a safe point of discharge where there

is no risk of injury to personnel or damage to property.

Spare parts

There are no spare parts available for this sealed, maintenance

free product.
