13.7 Hydronic connections
All connections should be made with the best available current workmanship practice according to the indicated dimensions
of inlet and outlet diameters.
Outlet connections should be complete with water traps and their height calculated on the basis of the maximum negative
pressure existing at the drainage point. A semplified method is to assume this value equal to the total fan pressure and calcu-
late trap dimension as indicated in the picture below.
S1 - S2 = minimum height, mm, as indicated
Ht = total fan pressure, Pa, as indicated in the “TECHNICAL SCHEDULE”
The lack of a siphon may affect the proper operation of the unit.
It is advisable to provide a siphon for EVERY SINGLE DRAIN. We also recommend that separated drains are NOT
connected with each other, before or after the siphon/s, but are left independent.
