9.6.3 Discharge connections
Connect the discharges from each condensate collection pan to the sewerage system either directly or via the manifold.
On each pan with discharge, fit a drain trap of suitable height so as to prevent air entering into the system by depression,
and stopping the correct drainage of the water. A correct drain trap also prevents the infiltration of bad smell.
The sizing and the construction of the drain trap must comply with the following formula: H >= P, where P, expressed in
mm w.c, is equal to the pressure gain of the unit installed.
The drain trap must be fitted with a bleeding cap at the lowest point, and must be made so as to allow quick dismantling
for more complete cleaning.
The path of the condensate drain pipe must always slope down towards the outside.
Check that the condensate drain pipe does not stress the discharge fitting on the unit.
