Condensate, drain and overflow lines
Provide all pan drains with a siphon (with backflow protection and self-filling). Dispose of wastewater
properly.
NOTE
Impairment of the function of the AHU due to incorrectly connected
lines.
If the condensate, drain, or overflow lines are connected incorrectly, air and water
will be drawn in and blown out through the lines. The function of individual
components may be impaired.
• Each pan drain from a drain pan must be connected individually with its own
siphon and a free outlet.
– The stand height of the siphon must be designed for the underpressure or
overpressure of the AHU.
Malfunction due to dry siphon
Only a siphon filled with water can perform its function. A siphon may dry out after a
long period of inactivity.
• Fill the siphon manually before commissioning.
• Use ball siphons for underpressure or overpressure (intake or discharge side).
