The installation site of the steam humidifier depends largely on the location
of the steam distributor (see chapter 5.4). To ensure proper functioning
of the steam humidifier and to obtain an optimal efficiency , the following
points must be considered and observed when choosing the location for
the steam humidifier:
– Install the steam humidifier 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 humidifiers Nordmann AT4 are designed for wall­mount­
ing. Make sure that the construction (wall, pillar, floor­mounted console,
etc.) to which the humidifiers are to be mounted, offers a sufficiently
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 humidifier directly to the ventilation duct
(insufficient stability).
– The back panel of the Nordmann AT4 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 unit is to be mounted, does not consist of heat­sensitive material.
– Install the steam humidifier in such a manner that it is freely accessible
with sufficient space available for maintenance purposes (refer to the
above illustration for minimum distances).
– The Nordmann AT4 is protected according to IP21 . Make sure the units
are installed in a drip­proof location and the admissible ambient condi­
tions are complied with.
– The steam humidifier Nordmann AT4 may only be installed in rooms
with a floor drain.
CAUTION!
If for some reason the Nordmann AT4 must be installed in a location
without floor drain, it is mandatory to provide a leakage monitoring
device to safely interrupt the water supply in case of leakage.
– When fixing the Nordmann AT4 use only the fixing materials supplied
with the unit . If fixing with the materials supplied is not possible in your
particular case, select a method of fixing that is of similar stability.
– The Nordmann ES4 is designed for installation and operation within
buildings (admissible temperature range see chapter 6.1). For outdoor
operation the Nordmann AT4 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 sufficient capacity. The water supply pipe must be
equipped with a trace­heating and must be insulated up to the protective
housing.
