5.3.2 Installingthemainsteampipe
Thesteampipebetweenthesteamoutletoftheunitandthesteamhoseadapter(mainsteampipe)
mustbemadewithsolidpiping.
Thefollowingnotesmustbeobserved:
– The internal diameter of the steam outlet on the unit must be maintained over the entire length
of the main steam piping.
– Themaximumlengthofthemainsteampipeis6m.
Important!Allowancemustbemadeforapressurelossof10mmwatercolumn(approx.
100 Pa)permeterlengthorper90°bend.
– The minimumbendradius for solid pipes is 4-5 x internaldiameter.90°bendsshould be
avoided.Whereverpossible,pipebendswithlargeradiusshouldbeused(e.g.producedusing
apipebendingmachine,orconstructedfromapairof45°bends).Thisreducestheperformance
loss due to the formation of condensate, and in addition, the static pressure in the steam line.
– UseCupipe(foroperationwithuntreateddrinkingwateronly)orstainlesssteelpipe(min.DIN
1.4301)exclusively.
– To minimize the condensate formation (= loss), the steam pipes must be insulated over the entire
length of the piping.
– Connection of the steam pipe to the steam outlet on the unit and the connection on the steam
hoseadapteriseffectedbymeansofshortlengthsofsteamhosesecuredwithhoseclamps.
– Atspotswherecondensatecouldaccumulateinsidethepipeacondensatedrainwithsiphon
(min. hose bend Ø200 mm) must be mounted.
