Condair EL before carrying out any work.
Knowing and understanding the contents of the operation manual is a basic requirement for protecting
personnel against any kind of danger, to prevent faulty operation, and to operate the Condair EL safely
and correctly.
All icons, signs and markings applied to the components of the Condair EL must be observed and kept
in readable state.
Qualicationofpersonnel
All work described in this operation manual may only be carried out by specialists who are well
trainedandadequatelyqualiedandareauthorizedbythecustomer.
For safety and warranty reasons any action beyond the scope of this manual must be carried out only
by qualied personnel authorised by the manufacturer.
It is assumed that all persons working with the Condair EL are familiar and comply with the appropriate
regulations on work safety and the prevention of accidents.
The Condair EL steam humidier may not be used by persons (including children) with reduced physical,
sensory or mental abilities or persons with lacking experience and/or knowledge, unless they are super-
vised by a person responsible for their safety or they received instructions on how to operate the system.
Children must be supervised to make sure that they do not play with the Condair EL steam humidier.
Intended use
The Condair EL steam humidier is intended exclusively for airhumidicationviaasteamdistribu-
tororblowerpackapprovedbyCondairwithinspeciedoperatingconditions. Any other type of
application, without the written consent of Condair, is considered as not conforming with the intended
purpose and may lead to dangerous operation and will void any warranty.

DANGER!
Dangerofelectrichazard!
The Condair EL is mains powered. Live parts may be exposed when the door panels of the
steamhumidierareromoved.Touchinglivepartsmaycausesevereinjuryordangertolife.
Prevention: Before carrying out any work set the Condair EL out of operation as described in chapter
4.5 (switch off the unit, disconnect it from the mains and stop the water supply) and secure the unit
against inadvertent power-up.
WARNING!
Hot water vapour - Danger of scalding!
TheCondairELproduceshotwatervapour.Thereisdangerofscaldingwhencomingincontact
with hot water vapour.
Prevention: Do not carry out any work on the steam system during operation (steam lines, steam
distributor, blower pack, etc.). If the steam system is leaky set the Condair EL immediately out of
operation as described in chapter 4.5. Correctly seal the steam system before putting the unit into
operation again.
WARNING!
Danger of burning!
During operation the components of the steam system (steam cylinder, steam distributor, etc.)
get very hot (up to 100 °C). There is danger of burning when touching the hot components.
Prevention: Before carrying out any work on the steam system set the Condair EL out of operation as
described in chapter 4.5, then wait until the components have cooled down sufciently thus preventing
danger of burning.
Preventing unsafe operation
If it is suspected that safe operation is no longer possible, the Condair EL should immediately be
shut down and secured against accidental power-up according to chapter4.5. This can be the case
under the following circumstances:
– if the Condair EL is damaged
– if the electrical installations are damaged
– if the Condair EL is no longer operating correctly
– if connections and/or piping are not sealed
All persons working with the Condair EL must report any alterations to the unit that may affect safety to
the owner without delay.

10 Product Overview
3.2 Functional description
The Condair EL steam humidier is an atmospheric steam generator. It operates on the electrode heating
principle and is designed for direct room air humidication (with blower pack) and indirect humidication
(with steam distributor) in venti lating and air-conditioning systems.
Water supply
The water is supplied via a lter valve (accessory "Z261") to the steam humidier. It reaches the steam
cylinder via the inlet valve and the open ll cup.
Steam generation
Any time steam is requested, the electrodes are supplied with voltage via the main contactor. Simulta-
neously, the inlet valve opens and the water enters the steam cylinder from the bottom via the open ll
cup and lling hose. As soon as the electrodes come in contact with the water, current begins to ow
between the electrodes, generating heat and increasing the water evaporation rate. The more of the
electrode surface area that is exposed to conductive water, the higher the current consumption and thus
steam production.
Upon reaching the requested steam capacity, the inlet valve closes. If the steam generation decreases
below a certain percentage of the required capacity, due to lowering of the water level (e.g. because of
the evaporation process or drainage), the inlet valve opens until the required capacity is available again.
If the required steam capacity is lower than the actual output, the inlet valve is closed until the desired
capacity is achieved by lowering of the water level (evaporation process).
Level monitoring
A sensor, provided in the steam cylinder, detects when the cylinder water level is at the maximum. When
the sensor comes in contact with water, the inlet valve will close after a short delay.
Drainage
As a result of the evaporation and rell process, the conductivity of the water increases due to an escalat-
ing mineral concentration. Eventually, an inadmissibly high current consumption would take place if this
concentration process were permitted to continue. To prevent this concentration from reaching a value,
unsuitably high for the operation, a certain amount of water is perio dically drained from the cylinder and
replaced by fresh water.
Control
The steam production can be controlled via the internal or an external continuous Proportional (P)/
Proportional-Integral (PI) controller or with an On/Off control via an external humidistat.
