2 For your safety
General
Every person working with the humidication system Condair DL must have read and understood this
installation manual and the operation manual of the Condair DL before carrying out any work.
Knowing and understanding the contents of the installation manual and the operation manual is a basic
requirement for protecting the personnel against any kind of danger, to prevent faulty operation, and to
operate the unit safely and correctly.
All ideograms, signs and markings applied to the components of the humidication system Condair DL
must be observed and kept in readable state.
Qualication of personnel
All installation work described in this installation manual may only be carried out by specialists who
are well trained and adequately qualied and are authorized by the customer.
For safety and warranty reasons any action beyond the scope of this manual must be carried out only
by qualied personnel authorized by the manufacturer.
It is assumed that all persons working with the humidication system Condair DL are familiar and comply
with the appropriate regulations on work safety and the prevention of accidents.
Intended use
The humidication system Condair DL is intended exclusively for air humidication in AHU's or air
ducts within the specied operating conditions (see operation manual of the humidication system
Condair DL). Any other type of application, without the written consent of the manufacturer, is consid-
ered as not conforming with the intended purpose and may lead to the humidication system Condair
DL becoming dangerous.
Operation of the equipment in the intended manner requires that all the information contained in this
installation manual are observed (in particular the safety instructions).

7For your safety
Danger that may arise from the humidication system Condair DL
DANGER!
Danger of electric shock!
The control unit of the Condair DL and the pump motor inside the central unit (if applicable)
are mains powered. Live parts may be exposed when the control unit and/or the central unit
is/are open. Touching live parts may cause severe injury or danger to life.
Prevention: The control unit of the Condair DL must be connected to the mains only after all mounting
and installation work has been completed, all installations have been checked for correct workmanship
and all unit covers are relocated properly locked.
Important! The frequency converter in the control unit of systems with booster pump contains
capacitors. These can remain charged with a potentially deadly voltage for a certain period of
time after the control unit has been disconnected from the power supply. Therefore, wait at least
10 minutes after disconnecting the power supply. Then make sure the appropriate contacts on
the frequency converter and the terminals on the pump motor are free of voltage before starting
any work on these components!
WARNING!
Risk of injury
The ceramic plates of the post-evaporation unit are porous and have partial sharp edges. You
may injure your hands on this sharp edges or may injure your eyes by splintering ceramic parts
when handling the ceramic plates.
Prevention: when handling the ceramic plates always wear protecting gloves and goggles.
Preventing unsafe operation
All persons working with the humidication system Condair DL are obliged to report any alterations to
the unit that may affect safety to the owner without delay and to secure such systems against acci-
dental power-up.
CAUTION!
In order that the Condair DL does not remain in the error status unnoticed for a longer period of time
in the event of a malfunction, errors must be signaled via a remote error indication (e.g. via the error
relay of the remote operating and fault indication board or via the network via BACnet or Modbus).
Prohibited modications to the unit
No modications must be undertaken on the humidication system Condair DL without the express
written consent of the manufacturer.

4.1 Safety notes on mounting and installation work
Qualication of personnel
All mounting and installation work must be carried out only by well qualied and trained personnel
authorized by the owner. It is the owner’s responsibility to verify proper qualication of the personnel.
General notes
Prior to installation work, the ventilation system (into which the Condair DL is to be incorporated) must
be taken out of operation and secured against unintentional start-up.
It is mandatory to observe and comply with the instructions regarding the location and installation
of particular components of the Condair DL.
Observe and comply with all local regulations dealing with water and electrical installations.
Use only the mounting accessories included in the delivery for installing the various system compo-
nents. If for some special reasons an installation with the supplied installation accessories is not feasible,
choose a type of installation that is equally stable. In cases of doubt, contact your Condair distributor.
Safety
Some installation work requires removal of the unit covers of the control unit and the central unit. Please
note the following:
DANGER!
Danger of electric shock!
The control unit of the Condair DL and the pump motor inside the central unit (if applicable)
are mains powered. Live parts may be exposed when the control unit and/or the central unit
is/are open. Touching live parts may cause severe injury or danger to life.
Prevention: The control unit of the Condair DL must be connected to the mains only after all mounting
and installation work has been completed, all installations have been checked for correct workmanship
and all unit covers are relocated properly locked.
Important! The frequency converter in the control unit of systems with booster pump contains
capacitors. These can remain charged with a potentially deadly voltage for a certain period of
time after the control unit has been disconnected from the power supply. Therefore, wait at least
10 minutes after disconnecting the power supply. Then make sure the appropriate contacts on
the frequency converter and the terminals on the pump motor are free of voltage before starting
any work on these components!
CAUTION!
The electronic components inside the control unit of the Condair DL are very sensitive to
electrostatic discharge.
Prevention: To protect these components against damage caused by electrostatic discharge (ESD
protection) appropriate measures must be taken when the control unit is open for installation work.
