1 Introduction
1.1 First things rst!
Thank you for choosing the Condair MN.
The Condair MN has been built using state-of-the-art technology and in accordance with the latest safety
regulations. However, improper installation and use of the Condair MN may put users and/or third parties
at risk and may also cause damage to material assets.
To ensure safe, proper and cost-efcient operation of the Condair MN, please observe and comply with
all information and safety instructions in this documentation and in the instructions to the components
built into the humidier system.
Should you have any questions after reading these instructions, please contact your local Condair rep-
resentative. They will be pleased to help you.
1.2 Information about the planning and installation instructions
Delimitations
These planning and installation instructions are for the Condair MN in its various congurations. Options
and accessories are only described insofar as is necessary for proper planning and installation. Please
see the relevant instructions for additional information on the options and accessories.
If the Condair MN system is operated with the optional reverse osmosis system Condair RO-HB, the
english version of the installation and operation manual for the reverse osmosis system Condair RO-
HB can be downloaded using the following QR code:
The information in these instructions is limited to the planning and preparatory installation of a Condair
MN system and is aimed at groups of people who are appropriately trained and sufciently qualied for
the work in question.
These planning and assembly instructions are accompanied by various separate documents which are
included with delivery. Where necessary, these instructions may refer to these publications.

7For your safety
2 For your safety
General
All persons tasked to perform work on the Condair MN must read and ensure they have
understood the planning and installation instructions as well as the operating manual
for the Condair MN before starting work.
An understanding of the content of these planning and installation instructions and the
operating manual is a basic prerequisite for protecting personnel from danger, avoiding
improper installation and operating the device safely and properly.
All pictograms, signs and markings applied to the Condair MN components must be
observed and kept in a clearly legible condition.
Personnel qualications
All work described in this documentation may only be carried out by trained and suit-
ably qualied staff authorised by the operator.
Furthermore, for safety and warranty reasons, interventions may only be undertaken
by specialist personnel authorised by Condair.
It is assumed that all persons entrusted to work on the Condair MN are familiar with and
abide by the regulations on occupational health and safety and accident prevention.
Proper use
The Condair MN is intended only for direct air humidication of rooms within the speci-
ed operating parameters (see operating manual for the Condair MN). Any other use
without the written permission of Condair is deemed to be improper use and can render
the Condair MN hazardous.
Proper use also demands that all information in this documentation and the operating
manual (in particular, all safety and hazard information) is duly observed.

8For your safety
Hazards that may arise from the Condair MN:
DANGER!
Risk of electrocution
The Condair MN's central unit runs on mains power. If the central unit is open, live
parts may be touched. Touching live parts may cause severe injury or death.
That is why the central unit must be switched off and disconnected from the
mains power supply (remove the plug from the socket) before the central unit
is opened.
Warning!
UVC radiation
A UV lamp is built into the Condair MN's central unit. In principle this should
pose no risks, as it is installed in a radiation-proof housing. If the UV lamp is
operated outside of this housing, harmful UVC radiation may be released. This
may cause damage to the eyes and skin.
That is why the UV lamp must never be operated outside of the protective hous-
ing. The central unit must be switched off and disconnected from the mains
power supply (remove the plug from the socket) before the central unit is opened.
Warning!
Waste from damaged UV lamps may lead to injury and cause damage to human
health and harm to the environment.
That is why the waste from damaged UV lamps must be disposed of in accor-
dance with local provisions on hazardous substances and the site of the dam-
age must be cleaned properly.
CAUTION!
Leaky or defective water pipes/connections may lead to water damage.
That is why the central unit and any peripheral drain modules should, where
possible, be installed in a technical room with a water outlet that is only acces-
sible to a limited number of people.
We recommend equipping the central unit water outlet with hose breakage protection
(washing machine connection, by customer) or with leakage monitoring (by customer),
ensuring the water supply if the outlet pipe breaks.

9For your safety
Preventing hazardous operating conditions
If it is suspected that safe operation is no longer possible, the Condair MN should
immediately be shut down and secured against accidental power-up. Then, contact
the Condair representative. This can be the case under the following circumstances:
– if components of the Condair MN are damaged
– if the electrical installations are damaged
– if the Condair MN is no longer operating correctly
– if connections and/or piping are not sealed
All persons working with the Condair MN must report any alterations to the unit that
may affect safety to the Condair representative.
Unauthorized modications to the device
No additions or modications may be made to the Condair MN without the written
permission of Condair.
When replacing any defective components of the device, use only genuine accessories
and spare parts from your Condair representative.

3.3 System description
System design
The Condair MN consists of:
– a central unit;
– a water lter and an optional second water lter (both water lters with or without housing);
– one to max. two spray circuits with maximum 10 humidier units per spray circuit;
– a central drainage (drain module integrated into the central unit, see Fig. 2) or a peripheral drainage
(drain module installed in a separate room, see Fig. 3) per spray circuit.
The Condair MN system can optionally be equipped with a reverse osmosis system RO-HB (reverse
osmosis unit with ow tank) and a booster module to feed the Condair MN system with RO water (see
Fig. 3 and Fig. 4).
Note: The booster modules are available in a version for single systems (to feed a single Condair MN
system) and a version for multiple systems (to feed up to 3 Condair MN systems). In the case of mul-
tiple systems, the individual Condair MN systems can only be equipped with one water lter and
one booster module is required for each Condair MN system.

16 Product overview
Installing the humidier units
The humidier units are ush-mounted onto a ceiling or wall as standard. In concrete ceilings/walls
in new buildings, ush-mounting boxes must be placed in the relevant positions and connected using
guide pipes (0.98" (25 mm) in diameter for the insertion of hoses and CAN bus cables). When install-
ing humidier units in suspended ceilings in new or existing buildings, holes ø2.95" (ø75 mm)) must
be drilled in the appropriate places for the ush mounting of humidier units in the ceiling. Alternatively,
guide pipes must be installed between the humidier unit installation points (0.98" (25 mm) in diameter,
for the insertion of hoses and CAN bus cables).
