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

The oat 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 lter to complete maintenance, the oat drain can be set to the
position >>mechanically open<<. To do so, unscrew the knurled-head screw counterclockwise (left-hand turn) to stop.
