4.4.2 Condensate drainage through the float drain
Float drains are mechanical automatic condensate drains whose closing mechanism is triggered by the buoyancy of a
float body [1]. When the condensate [2] in the container raises above a certain level, the buoyant lift of the float body
[1] opens the outlet channel [3] for the condensate. The float closes again when the condensate [1] drops below a
certain level: A small amount of condensate remains in the container.
The following float drain is used to drain the condensate:
• Open when depressurized ([NO] normally open) - at an operating pressure ≤ 7.25 psi(g) the float drain opens

The float drain is delivered in the position >>Automatic drainage<<. The knurled-head screw is screwed down to the stop.
To test the drainage function or release pressure to the filter to complete maintenance, the float drain can be set to the
position >>mechanically open<<. To do so, unscrew the knurled-head screw counterclockwise (left-hand turn) to stop.
