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 humidier). 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 congured accordingly.
1. Examine the steam humidier 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 humidier.
The steam humidier 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 sufcient, 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 sufcient level (due to the vaporisation process) the humidier will reach
the requested steam capacity.
