10 Product Overview
3.2 Functional description
The Condair EL steam humidier is an atmospheric steam generator. It operates on the electrode heating
principle and is designed for direct room air humidication (with blower pack) and indirect humidication
(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 humidier. 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 rell 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.

13Operation
4 Operation
The Condair EL steam humidier may be commissioned and operated only by persons familiar with the
Condair EL steam humidier and adequately qualied. It is the owner’s responsibility to verify proper
qualication of the personnel.
4.1 First-time commissioning
The rst-time commissioning must always be done by a service technician of your Condair representative
or a well trained and authorised person of the customer. Therefore the current manual does not provide
detailed information on this procedure.
The following steps are carried out upon rst-time commissioning in the specied order:
• Inspecting the steam humidier for correct installation.
• Inspecting the electrical installation
• Inspecting the water installation
• Inspecting the steam installation
• Flushing the water supply line.
• Conguring the control or the Condair EL , respectively.
• Carrying out test runs including checking of the control and monitoring devices.
• Filling in the commissioning protocol.
4.2 Display and operating elements

14 Operation
4.3 Commissioning after an interruption of operation
The following description outlines the start up procedure after an interruption of operation (e.g. after servic-
ing the steam humidier). It is assumed that rst-time commissioning has been carried out properly by the
service technician of your Condair representative and the Condair EL has been congured accordingly.
1. Examine the steam humidier and installation for possible damage.
DANGER!
A damaged unit or systems with damaged installations may present danger to human life
or cause severe damage to material assets.
Therefore: Damaged systems and/or systems with damaged or faulty installations must
not be operated.
2. Mount front doors of the unit and lock them (if applicable).
3. Open the lter valve (or the shut-off valve, respectively) in the water supply line.
4. Make sure the ventilation system is running and the external safety chain (e.g. ventilation interlock,
air proving switch, etc.) is closed.
5. Switch on the electrical isolators in the mains supplies (heating and control voltage).
6. Switch on the unit switch of the steam humidier.
The steam humidier carries out an automatic system test (initialising). If a fault is detected during
the system test, a corresponding fault message is shown in the maintenance and malfunction indi-
cation eld (see chapter 5.1.2).
If the initialisation is successful, the Condair EL will be in normal operating mode and the
standard operating display is shown.
As soon as the humidity controller or the humidistat requires humidity in excess of the minimum
required system demand, the LED will change to solid green and the power for the electrodes will
be activated. The inlet valve opens (slight delay) and the steam cylinder lls with water. As soon as
the electrodes are submerged, heat will start to be generated depending upon the conductivity of
the water. When the heat is sufcient, steam will be produced.
Note: If the Condair EL is operated with water of low conductivity, it may happen that the requested
steam capacity is not reached in the rst few hours of operation. This is normal. As soon as the
conductivity has reached a sufcient level (due to the vaporisation process) the humidier will reach
the requested steam capacity.

15Operation
4.4 Notes on operation
4.4.1 Inspections during operation
During operation the Condair EL and the humidication system have to be inspected weekly. On this
occasion check the following:
• the water and steam installation for any leakage.
• the steam humidier and the other system components for correct xing and any damage.
• the electric installation for any damage.
• the display for possible warning or fault indication.
If the inspection reveals any irregularities (e.g. leakages, fault indication) or any damaged components take
the Condair EL out of operation as described in chapter 4.5. Then, contact your Condair representative.
4.4.2 Remote operating and fault indication
Via the relays on the operating and fault indication board the following operating status are indicated:
