3 Water reservoir
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 reservoir 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 humidity
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 obstructions.
In the following table you nd the minimum distances (appoximate values), which must be main-
tained 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.
