Possible installation at the

customer side: funnel

Siphon installation

Ensure that there is a sufﬁ cient height difference between the fan pan and the upper bow of the siphon or the

highest part of the drain tube, in order to avoid a water column in the drain siphon caused by the pressure

in the suction area of the cooling unit, which prevents the draining of the condensate water.

Connect the condensate water drains to the local waste water system.

Note:

Comply with regulations in accordance with state and local codes.

Example: Static pressure in the suction area :

–1 in.w.g. (–250Pa)

h = p / (ρ • g)

h = –250Pa / (1000kg/m³ • 10m/s²)

h = –1 inch (h = –2.5 cm)

If the height h is less than 1 inch (2.5 cm) with a

pressure of 1 in.w.g. (250 Pa) in the suction area,

a water column rests in the drain. The water is

not transported and ﬁ lls the fan pan. This water

can be drawn down in the fan or can be drained

out of the unit if the pan is full.

6.3.4 Condensate drain connection

The condensate drain connection (3/4 in) is

located in the middle section, right bottom.

The siphon is delivered with the unit and has

to be mounted in the raised ﬂ oor on site after

the cooling unit has been installed.
