4.3 Positioning and mounting the central unit
Positioning the central unit
– The central unit is designed for wall-mounting in interior spaces. Make sure that the construction (duct
wall, pillar, etc.) to which the central unit is to be mounted, offers a sufciently high load-bearing
capacity, and is suitable for the installation.
CAUTION!
Do not mount the central unit to vibrating components, not in exposed areas or places with exces-
sive dust load.
– The central unit may only be installed in rooms with a oor drain. If for some reason the central unit
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. Additionally make sure that in case of
a water leakage not material assets can be damaged.
– Locate the central unit in such a manner that:
– the length of the spray circuit lines between central unit and housing feed throughs of the duct
are as short as possible (max. 10 m).
– the spray circuit lines can be installed with a constant downslope (min. 2%) from the housing
feed throughs on the duct/AHU to the connections of the central unit.
– the central unit is freely accessible with sufcient space available for maintenance purposes
(minimum distances showed in the following illustration must be adhered to).
– the control unit can be mounted in direct proximity to the central unit (max. length of the electri-
cal connecting cables between control unit and central unit 0.75 m)
– The central unit is protected according to IP22. Make sure the central unit are installed in a drip-proof
location and the admissible ambient conditions are complied with.
– When xing the central unit 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.
