20 Operation
4.3 Recommissioning after interruption of operation
The following description outlines the recommissioning procedure after an interruption of the opera-
tion (e.g., after servicing the system). It is assumed that first-time commissioning has been carried out
properly by the service technician of your Condair representative. Proceed as follows to prepare the
humidification system Condair DL for operation:
1. Examine the system components and installations for possible damage.
DANGER!
Damaged systems or systems with damaged components or installations may present danger to
human life or cause severe damage to material assets.
Damaged systems and/or systems with damaged or faulty installations must not be operated.
2. Make sure the ceramic plates are correctly located and properly sealed.
WARNING!
An unsealed post-evaporation unit may lead to severe damage of material assets.
Put the system into operation only if the ceramic plates are correctly positioned and the
post-evaporation unit correctly sealed.
3. Switch on the electrical isolator in the mains supply line (mains supply to control unit).
4. If closed, open shut-off valve in the water supply line.
5. Switch
<Control unit On/Off> on the control unit to " On ", and activate control unit via the external
enable switch if necessary.
6. If the humidification system Condair DL has been disconnected from the mains for more than 48
hours the message "Out of Commissioning" appears. If this is the case proceed as follows:
• Switch off control unit via the
<Control unit On/Off> switch.
• Close shut-off valve in the water supply line.
• Disconnect the water supply line from the connector on the central unit.
• Lead the open end of the water supply line into open funnel of the waste water line of the build-
ing.
• Open the shut-off valve in the water supply line and flush the supply line for at least 5 minutes.
Close shut-off valve in the water supply line again. Reconnect the water supply line to the con-
nector on the central unit and open the shut-off valve.
• Switch on control unit via the <Control unit On/Off> switch.
Note: After switching on the control unit the "Out of Commissioning" message appears again. After
5 minutes, the Condair DL automatically flushes the water system and then goes into normal operat-
ing mode. The message is reset.
7. If the sterile filter has been replaced, deaerate the sterile filter as described in Section 6.6 .
The humidification system Condair DL is now in normal operating mode and the home screen is
shown in the display.
Note: Further information on the operation of the Condair DL control software can be found in Section 5 .
