2) To fully exploit the overall capacity of your humidier, the output of each steam outlet may be fed to more than
one steam distribution pipe. If more than one steam distribution pipe is fed per steam outlet the steam line must
be divided into multiple branches. Appropriate adapters are available on request.
Note: If the absorption distance has to be reduced for technical reasons, the amount of steam per unit
must be divided between several steam distribution pipes or the steam distribution system OptiSorp
must be used. If this is the case, contact your Condair representative.
Note: for further information regarding the DV81-... steam distribution pipe please refer to the separate
installation and operating instructions of this product.

5.3 InstallationSpaceRequirements
In preparation for installation of the Condair GS humidier ensure that the following installation space
requirements are satised. Report any discrepancies to the site engineer.
– The installation space must comply with the applicable local and national regulations for the instal-
lation of gas-red appliances.
– The room in which the Condair GS is to be installed should be lockable if possible.
– The installation room must be protected against dripping water and must have the following tem-
perature and humidity values throughout the year:
Room temperature: +15°C to +30°C
Room humidity: 15 %rh to 75 %rh (non condensing)
– There must be no ammable materials (e.g. wooden oors, carpets, etc.) or other sensitive materials
in the installation room.
– Sufcient space must be available for operation and maintenance at the place of installation of the
Condair GS humidier.
– The oor surface or wall surface on which the Condair GS humidier is mounted must be level, have
sufcient load-bearing capacity (for maximum operating weights, see Table 2) and be suitable for
mounting (no vibrating, hot or very cold surfaces).
– The oor surface or wall surface on which the Condair GS humidier is mounted must be able to
withstand temperatures of 60-70 °C.
– There should be a oordrain in the installation room that is connected to the building's waste water
line. If there is no oor drain in the room, the room must be equipped with a leakage monitoring
device which automatically shuts off the water supply in the event of a water leak.
– It must be possible to install the Condair GS humidier in the room in such a way that the maximum
permissible length of the steam line between the humidier and the steam distributor(s) is not ex-
ceeded, the minimum bend radii of the steam line are observed and that the steam pipe/steam hoses
can be laid with a constant upslope or downslope (see notes on steam installation in Section 5.6).
– A water supply connection (drinking water, RO water or deionized water) must be available or be
made in the installation room. Please note the information on water supply in Section 5.7).
– In the installation room, depending on the location of the Condair GS humidier and the steam
distributor(s), there must be one or two open drain funnels with trap, which is/are connected to the
building's waste water line (see notes on water installation in Section 5.7.
– The building's waste installation must be made of heat-resistant material that is designed for drain-
age water of up to 100 °C.
– The room in which the Condair GS humidier is to be installed must have a sufciently large air sup-
ply opening (in-room air installation) or a combustion air supply via a pipe from the outside (room
seal installation). Please note the information in Section 5.8.
– The room in which the Condair GS humidier is to be installed must allow exhaust gas discharge to
the outside. Please note the information on exhaust gas installation in Section 5.9.
– In the installation room a gas supply connection must be available or be made. Please note the
information on gas installation in Section 5.10).
– The installation room must be equipped with a 230V/1~/50-60 Hz power supply. Please note the
information on electrical installation in Section 5.12).
