Forsteamlineswithxedpiping,thesameinstructionsapplytothelayingofthepipingasalready
described.Thefollowingadditionalnotesshouldbeobserved:
– The minimuminternaldiameterof45mmshouldbeappliedoverthewholelengthofthepiping.
– UseexclusivelyCupipe(foroperationwithuntreateddrinkingwateronly)orstainlesssteel(min.
DIN 1.4301).
– To minimize the condensate formation (=loss), the steam pipes must be insulated.
– The minimumbendradius for solid pipes is 4-5xinternaldiameter.
90°bendsshouldbeavoided.Whereverpossible,tubebendswithlargeradiishouldbeused(e.g.
producedusingatube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.

5.3.4 Installing the condensate hoses
The individual condensate hoses of the main steam pipe (if present), the steam hose adapter (if
present)andthesteamdistributionpipesmustbeleddownwithaminimumdownslopeof20%
via a siphon (min. hose bend ø200 mm) into a discharge funnel.
Important!Beforeputtingtheunitintooperation,thesiphonofthecondensatehosemustbelled
withwater.
Important!UseoriginalCondaircondensatehoseexclusively.Othertypesofhosescancauseoper-
ational malfunctions.
