Important! Use original steam and condensate 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 distributor:
– Steam distributor is mounted more than 500 mm above the top edge
of the steam generator:
Ømin. 200 mm
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
distributor.
The condensate hose is led down to the humidifier with a minimum slope
of 20 %, in the form of a siphon (min. hose bend diameter Ø200 mm)
and is to be connected to the appropriate connector on top of the unit.
Important! Before putting the unit into operation, the siphon of the
condensate hose must be filled with water.
