The installation site of the steam humidier depends largely on the location
of the steam distributor (see chapter 5.4). To ensure proper functioning
of the steam humidier and to obtain an optimal efciency, the following
points must be considered and observed when choosing the location for
the steam humidier:
– Install the steam humidier so that the length of the steam hose is kept
as short as possible (max. 4 m) and that the minimum bend radius
(R= 300 mm) and up-slope (20 %) or down-slope (5 %) of the steam
hose is observed (see chapter 5.4.5).
– The steam humidiers Nordmann ES4 are designed for wallmount-
ing. Make sure that the construction (wall, pillar, oormounted console,
etc.) to which the humidiers are to be mounted, offers a sufciently
high load-bearing capacity (take notice of the weight information
found in the dimensions and weights table above), and is suitable for
the installation.
CAUTION!
Do not mount the steam humidier directly to the ventilation duct
(insufcient stability).
– The back panel of the Nordmann ES4 is retaining heat during operation
(max. surface temperature of the metal housing approx. 60  70 °C).
Make sure, therefore, that the construction (wall, pillar, etc.) to which
the units are to be mounted, does not consist of heatsensitive material.
– Install the steam humidier in such a manner that it is freely accessible
with sufcient space available for maintenance purposes (refer to the
above illustration for minimum distances).
– The Nordmann ES4 is protected according to IP20. Make sure the units
are installed in a dripproof location and the admissible ambient condi-
tions are complied with.
– The steam humidier Nordmann ES4 may only be installed in rooms
with a oor drain.
CAUTION!
If for some reason the Nordmann ES4 must be installed in a location
without oor drain, it is mandatory to provide a leakage monitoring
device to safely interrupt the water supply in case of leakage.
– When xing the Nordmann ES4 use only the xing materials supplied
with the unit. If xing with the materials supplied is not possible in your
particular case, select a method of xing that is of similar stability.
– The Nordmann ES4 is designed for installation and operation within
buildings (admissible temperature range see chapter 10.1). For outdoor
operation the Nordmann ES4 must be placed in a weather protective
housing. If ambient temperatures near or below the freezing point have
to be expected, the protective housing must equipped with a thermostat
controlled heating of sufcient capacity. The water supply pipe must be
equipped with a traceheating and must be insulated up to the protective
housing.
