5.4.3 Installing the steam and condensate lines
5.4.3.1 Notes on installation
– Use original steam and condensate hose from your Condair 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.
– Initially, lead the steam line upright upwards min. 300 mm above the steam generator. Then lead
the steam line with a minimum upslope/downslope of 15 %/8.5° to the steam distributor.
Important: ensure the steam hose can be disconnected later on from steam outlet connector on
steam tank for maintenance purpose. For that purpose the steam hose may be led more than
500 mm upright upwards.
– The condensate hose from the steam distributor is led down to the steam generator with a minimum
downslope of 15 %/8.5°, via a condensate trap (min. hose bend diameter Ø200 mm) and there
it is to be connected to the appropriate connector on top of the unit (left connector= condensate
ows back into the steam tank (not recomended), right connector= condensate ows into the drain).
Alternatively the condensate hose can be led also directly into an open funnel.
Important! Before putting the unit into operation, the condensate trap of the condensate hose must
be lled with water.
– The steam line should be kept as short as possible (max. 4 m while observing the minimum bend
radius of 300 mm (for steam hoses) or 5 x internal diameter (with solid steam pipes), respectively.
Important! Allowance must be made for a pressure loss of approx. 100 Pa per meter steam line
and per 90° elbow.
– Important! When deciding on the length and layout of steam hoses, it should be noted that steam
hoses may become shorter and/or longer depending on temperature and age.
– The steam hose must be secured to the steam distributor and steam generator steam outlet by
means of hose clamps. Solid steam pipes should be connected to the steam distributor and steam
generator with short lengths of steam hose secured with hose clamps.
Caution! Do not overtighten the hose clamp on the steam connector of the steam generator.
WARNING!
Make sure that there is no tension on the steam hose since this could result in lifting the steam

with a strain relief device.
– Steam lines made of solid pipes (copper or stainless steel) must be insulated over the entire length
to minimize condensate formation (=loss).
DANGER!
Reducing the cross section or the complete closure of the steam line will cause an excessive
increase in pressure in the steam tank when the unit is operating and could lead to the risk of
scalding accidents. All installations must comply with the following instructions.
– When installing make sure the steam line is open over the entire length and through the whole cross
section. Any sealing plugs, adhesive sealing sheets etc. must be removed before connecting the
steam pipe. Reductions in cross section by kinking or crushing must be avoided.
