Simplified Pipe Planning

Simplified planning is used for equipment protection and in premises with smaller
dimensions. The benefit of this type of planning is the standard diameters of the suction
openings.
Planning is to be carried out according to regulations specified in Section 3.6 Standard Pipe
Planning, page 37. Additionally, the following limiting values and opening diameters must be
observed. An additional accessory (air filter, condensate separator etc.) can have an effect on
the maximum pipe length.
