– The steam hose should be kept as short as possible (max. 4 m) while
observing the minimum bend radius of 300 mm. Important! Allowance
must be made for a pressure loss of 10 mm water column (approx.
100 Pa) per meter steam hose.
Note: If your particular installation exceeds the maximum steam hose
length of 4 m contact your Nordmann representative. In any case, steam
hoses longer than 4 m must be insulated in their entire length (e.g. with
insulation hose “EcoTherm”).
– Reductions in the cross section such as kinks should be avoided through-
out the entire length of the hose. The installation of a stop cock in the
steam hose is not permissible.
– Steam hoses must be prevented from sagging (condensate pockets); if
necessary, support with pipe clamps, trough, or wall brackets, or install
a condensate drain in the steam hose.
– Important! When deciding on the length and layout of the hose, it
should be noted that the steam hose may become somewhat shorter
with progressive ageing.
Securing the hose
The steam hose must be secured to the steam distribution pipe and humidi er
steam outlet by means of hose clamps.
Caution! Do not overtighten the hose clamp on the steam connector of the
steam humidier.
