4 Cone with fan
5 Atomiser disk
6 Motor
7 Discharge hood, rotatable
3.2 Principle of operation
The Condair ABS3 operates according to the atomization principle.
The water is drawn in through cone (4) from the water reservoir (3) and is hurled from the atomiser
disk (5) against the atomiser collar (8), thereby producing aerosols (fog). The level in the water res-
ervoir is monitored and controlled with the oat switch (10).
The fan attached to the cone draws in room air through the air lter (1) on the bottom of the base
unit. This air transports the aerosols to the atomiser outlet (7) and distributes them in the room.
The humidier is controlled via an external On/Off humidistat or an external 0-10V continuous humid-
ity controller which opens and closes the inlet valve. When controlled via the external continuous
humidity controller the inlet valve is opened and closed cyclically, depending on the control signal.

4.2 Mounting the unit
4.2.1 Notes on unit location
In order to ensure the correct function of the humidier and the accessibility for maintenance, please
observe the following locating instructions:
– The Condair ABS3 humidiers are designed for wall mouting or ceiling mounting (hanging instal-
lation). Make sure that the structure (wall, pillar, ceiling, etc.) on which the unit is to be mounted
has sufcient carrying capacity and can accommodate the fastening elements.
– In order to ensure the correct function, the Condair ABS3 must be installed exactly horizontal
(with the air lter facing downward against the oor).
– Locate the unit such that the aerosol stream can spread freely. The obstruction of the aerosol
stream by objects such as tubular racks, machines, supports, etc., will result in stagnation and
the formation of turbulence which could cause condensation. Since the discharge hood of the
humidier can be turned horizontally, the aerosol stream can be directed to bypass any obstruc-
tions.
In the following table you nd the minimum distances (appoximate values), which must be
maintained when positioning the Condair ABS3. The dimensions relate to a room temperature of
20 °C and a relative humidity of 45 %. At lower temperatures and/or higher relative humidity larger
minimum distances must be maintained

– Mount the unit such that there is sufcient room for maintenance. Also make sure that the unit
is readily accessible and that there is no accident risk during maintenance.
– If units are to be installed facing each other, make sure that they are at least 10 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.
