5.4.5 Installing the steam hose
Important! Use original steam and condesate hose from your Nordmann
supplier exclusively. Other types of hoses can cause undesired operational
malfunctions.
Instructions for the hose layout
The hose layout depends on the position of the steam distribution pipe:
– Steam distribution pipe is mounted more than 500 mm above the top
edge of the humidier:
Initially, lead the steam hose with an upslope of at least 20% over
a minimum height of 300 mm, then lead the hose with a minimum
upslope of 20% and/or a minimum downslope of 5% to the steam
distribution pipe.
The condensate hose is led down to the humidier with a minimum slope
of 20 %, in the form of a siphon (min. hose bend diameter Ø200 mm),
and inserted into the specied opening until it comes to a stop.
Note: If your unit feeds a number of steam distribution pipes, the indi-
vidual condensate hoses are to be led into a discharge funnel.
Important! Before putting the unit into operation, the siphon of the
condensate hose must be lled with water.
