When the maximum length of the ue systems is exceeded, as shown in table [4], the diameter of
the single ue sets, including extension pipes and elbows, must be increased by one size.
Caution:
- The values shown in the resistance table [4] apply only to the delivered and advised ue systems
supplied by the manufacturer.
- Discharge material with a different resistivity can inuence the length of the total supply and
discharge route.
- The Ph-value of condensate is 3.4!
