not be routed to one shared siphon (* drain blocked).

The hydraulic seal in the siphon H must be greater than the maximum
overpressure or underpressure (mm WC) in the unit (1 mm WC = 10
Pa).
The dimensioning is performed using the equation below:
H(mmWC) =
Unit over-/underpressure(Pa)
10
The height difference between the water drain and hydraulic seal must
also correspond to the dimension H (mm WC).
• Connect the siphon to the waste water system as shown in the
illustration.
NOTE ON RISK OF FROST.
If there is a risk of frost, the discharge pipe must
be insulated and kept warm using a heating cable,
for example.
NOTE
Underpressure and overpressure siphons must be connected to separate collecting pipes (Refer
to fig. 7-2).
Installation of accessories
Refer to the relevant documentation provided for descriptions of the assembly and installation of
accessories or accessory parts by others.
