11. Initial Operation
Risk of injuries when the device is handled improperly.
The unit may only be started up by qualified personnel.
Before starting up the device for the first time, the following operations
must be well known:
How to switch off the steam generator:
» Switch off unit by means of the control switch.
» Close the water supply shut-off cock.
How to switch on the steam generator:
» Open supply water shut-off cock.
» Switch on unit by means of the control switch.
The following functions are executed during the start-up routine:
• The unit performs self-tests.
• The LEDs on the control panel light up briefly in succession.
• Subsequently, the blow-down pump is activated for a few sec-
onds. This step checks pump operation and partial water
exchange during restart (applies only to electrode steam humidi-
fiers).
• After self-tests are completed, the display reads:
If the cabin temperature is a) below setpoint of temperature and b) if
the safety interlock is closed (please see also chapter „Remote
Switch / Safety Interlock)
the humidifier starts to produce steam.
Additional Checks:
All electrical functions must be available.
As soon as the solenoid valve periodically feeds water, operation with
nominal output has been achieved and the cold start-up procedure is
completed.
» Monitor the unit and allow to run for 15-30 minutes. If leakage
occurs, switch off the unit.
» Repair leaks.
Risk of electrical shock!
Follow safety instructions for work on live components.
Unit cover must be in place and secured.
