Defensor ABS2 Installation and Operating Instructions

– Humid air rises because it is lighter than dry air. Therefore a minimum
distance must be maintained between the ceiling of the room and the
appliance. This prevents the aerosol stream from condensing on the
ceiling.
Note: If there are support elements (e.g. ceiling joists, roof beams) in the
vicinity of the aerosol stream, the minimum distance applies to the bottom
surface of the support element.

– Mount the appliance such that there is sufficient room for maintenance.
Also make sure that the appliances are readily accessible and that there
is no accident risk during maintenance.
– If appliances are to be installed facing each other, make sure that they
are at least 15 to 20 m apart.
– Insulate cold water piping in the vicinity of the aerosol stream (risk of
condensation).
– The evaporation process extracts heat from the ambient air. Make sure,
therefore, that the aerosol stream is not directed at persons.
– The base unit must be level (longitudinally and transversely) to ensure
correct operation.
Locating the external humidistat
To ensure correct control of the Defensor ABS2 please observe the notes
on appropriate location of your humidistat (e.g. Defensor H5 humidistat ).
