Page 24: Installing The Steam And Condensate Lines
6.4.3 Installing the steam and condensate lines 6.4.3.1 Notes on installing the steam and condensate lines – Use original steam and condensate hose from your Nordmann representative or solid steam pipes from copper or stainless steel (min. DIN 1.4301) exclusively. Steam and condensate lines from other material may cause undesired operational malfunctions. - Page 25 – Steam hoses must be prevented from sagging (condensate pockets); if necessary, support steam hose with pipe clamps, trough, or wall brackets, and install a condensate drain at any low points in the steam line. – It is not permitted to install a stop valve (e.g. a manually controlled stop valve, solenoid valve, etc.) in the steam line, due to an inadmissible increase of pressure in the steam tank if the valve is closed during the operation.
