Hydraulic seal H of the trap must be greater than the maximum
positive or negative pressure (mm water column) in unit (1 mm
WC = 10 Pa).
Use the following equation for the dimensioning:
The vertical difference between the water drain and hydraulic
seal must also correspond to the dimension H (mm WC).
Notice!
Direct connection to a sewage network is not allowed! Fill the condensate trap with
water prior to commissioning and after extensive downtime periods.
