Installation of Components and AccessoriesGEA CAIRplusThe hydraulic seal in the siphon H must be greater thanthe maximum overpressure or underpressure (mm WC)in the unit (1 mm WC = 10 Pa).The dimensioning is performed using the equationbelow:H( mmWC)=Unit over-/underpressure( Pa)------------------------------------------------------------------------------10Fig. 6-1:Siphon: overpressure in unitThe height difference between the water drain andhydraulic seal must also correspond to the dimensionH (mm WC).• Connect the siphon to the waste water system asshown in the illustration.2,5 HH1,5 HNOTE ON RISK OF FROST.If there is a risk of frost, the discharge pipemust be insulated and kept warm using aheating cable, for example.Fig. 6-2:Siphon: underpressure in unitFig. 6-3:A siphon must be connected to each condensate drain or overflow pipe. Several discharge pipes mustnot be routed to one shared siphon (* drain blocked).NOTEUnderpressure and overpressure siphons must be connected to separatecollecting pipes (Refer to fig. 6-3).6.4 Installation of accessoriesRefer to the relevant documentation provided for descriptions of the assemblyand installation of accessories or accessory parts by others.42 PR-2009-0096-GB • Subject to modifications • Status 07/2010
