Syphon installation
Ensure that there is a sufficient height difference between the fan pan and the upper bow of the syphon or the highest
part of the drain tube, in order to avoid a water column in the drain syphon caused by the pressure in the suction
area of the A/C unit, which prevents the draining of the condensate water
Connect the condensate water drains to the local waste water system.
Comply with the regulations of the local water supply authority.
Example:
Static pressure in the suction area:
-300Pa
h = p / (ρ • g)
h = -300Pa / (1000kg/m³ • 10m/s²)
h = -3 cm
If the height h is smaller than 3 cm with a pressure of 300
Pa in the suction area, a water column rests in the drain,
the water is not transported and fills the fan pan. This water
can be drawn dropwise in the fan or can drop out of the
unit if the pan is full.

The condensate drain connection is located
right backmost.
