3.7.2.3 Fan units FAN4 N...

The fan units FAN4 N... – in combination with the steam humidifiers Nor

dmann AT4 – are used for direct room humidification. The fan units

FAN4

N S D

and

FAN4 N M D

are

mounted directly on the humidifier.

The fan

units

FAN4 N S W

FAN4 N M W

und

FAN4 N L W

are mounted separately

above the humidifier to the wall

The type and number of fan units are dependent on the steam capacity

and on the type of the humidifier and can be gathered from the table in

chapter 3.7.1.
Note: Further information on the fan units FAN4... can be found in the sepa

rate manual supplied with the fan unit.

Important note regarding the IP protection class

: If a Nordmann AT4

with fan unit FAN4 N... shall be operated without the fan unit at a later date

(e.g. retrofitting for duct humidification) the open bores in the housing ceil

ing must be sealed with plugs, otherwise the protection class IP21 is not

assured anymore.
