Initial commissioning and operation
Note: The draught limiter balances out the pressure fluctuations arising from the minimum and
maximum exhaust air output. At minimum exhaust air output the draught limiter should be closed.
9. Start the steam air humidifier at 100% performance in accordance with the instructions in the operation
manual of the Condair GS. The negative pressure in the exhaust gas pipe must not fall below -20 Pa
at minimum exhaust air system output (check with a pressure gauge).
Note: If you cannot start the steam air humidifier because the negative pressure in the exhaust gas
pipe at start up falls below -20 Pa (differential pressure switch has triggered) the draught limiter
weights must be moved clockwise until the negative pressure at start up no longer falls below -20 Pa.
Then steps 5 - 7 must be repeated until the system is balanced and works without any problems in
the permissible negative pressure range of -20 Pa to -100 Pa.
10. Seal the position of the throttle valve.

Operation
If the Condair GS steam air humidifier with the optional exhaust gas management system has been
started up correctly as described in Chapter 6.1 the steam air humidifier can be operated normally from
now on (see installation and operating instructions for the Condair GS). If the Condair GS cannot be
started up or if there are problems while it is operating, follow the troubleshooting instructions in
The differential pressure switch and the flow monitor monitor the operation of the DVGW-certified exhaust
gas management system and ensure that the steam air humidifier can only be started up or operated
when the negative pressure in the exhaust gas pipe is within the permitted range.
