6.3.3 Inspections during operation
During operation the Condair Sigma 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 generator and the other system components for correct xing and any damage.
• the electric installation for any damage.
If the inspection reveals any irregularities (e.g. leakage, error indication) or any damaged components
take the Condair Sigma out of operation as described in chapter 6.5. Then, contact your Condair rep-
resentative.

Proceed as follows to drain the unit manually:
1. Brieypressthedrain/infokey. The heating voltage is interrupted and the drain
valve opens. The yellowLEDashes.
Note: the drain valve closes after 10 minutes automatically
2. To stop the drain cycle brieypressthedrain/infokeyagain.
6.5 Taking the unit out of operation
In order to take the steam generator out of operation, perform the following steps:
1. If the unit has to be switched off because of a malfunction, please note the error code (number of
ashes of the red and yellow LED) of the actual error.
2. Close the shut-off valve in the water supply line.
3. Start manual draining (see chapter 6.4) and wait until the steam cylinder is empty.
4. Actuate the unit switch.
5. Disconnect steam generator from the mains: Switch off all electrical isolatores to mains supplies
(heating and control voltage) and secure switches in "off" position against accidentally being switched
on, or clearly mark the switches.
WARNING!
Danger of burning!
If steam was produced just before the unit is taken out of operation, wait before opening the unit and
let the steam cylinder cool down to prevent danger of burning.
