Fagor SR-11 Bedienungsanleitung Seite 81

It is advisable that the outlet pipe be as long as possible. It is advisable that this does not exceed
4 metres and 2 elbows at 90º and that it has a slope of 2% in the direction to the outside in the
horizontal sections, to prevent condensation from returning to the machine.
Note: For facilities with more linear metres of pipeline and/or more elbows consult the
technical service. It may be necessary to increase the diameter of the pipeline or even
install in the facility an auxiliary vacuum.
It is preferable for each machine to have its own separate steam outlet. If this is not possible:
It is COMPULSORY to install a check valve for each of the machines before reaching the
head pipe.
Connections always in Y, never in T.
Increase the section before connection so that the final section is the sum of the two

previous ones.
IMPORTANT: Some fresh air inlets must be foreseen in the room to allow the inlet of the
volume of air that has to be extracted (see section 3.3.1).
A table is included below where the equivalent diameter necessary can be consulted when
connecting several dryers to one common steam outlet and the minimum fresh air inlet area (see
section 3.3.1):
Number of dryers
Diameter of the output pipe
(mm)
Minimum area of the fresh air
inlet to the premises (m²)
