Initial commissioning and operation
6.1
Initial commissioning
Initial commissioning must be carried out by a service engineer from your Condair representative.
The customer must not perform the commissioning.
It is assumed that the optional exhaust gas management system has been installed correctly in accordance
with the installation and operating instructions and the person entrusted with the commissioning has
read and understood the installation and operating instructions for the optional exhaust gas management
system of the Condair GS and the installation manual and operation manual of the Condair GS steam
air humidifier.
Proceed as follows for initial commissioning:
1. Condair GS is switched off.
2. Set the
differential pressure switch
on the exhaust gas pipe to
-20 Pa
(see instructions for the
differential pressure switch KS...C2).
Set value:
3. Set the
flow monitor
in the exhaust air duct to
1m/s
(see instructions for the INT511 flow monitor).
Set value:
4. Connect the
pressure gauge
to the measurement connection in the exhaust gas pipe.
5. Turn the draught limiter weights anti-clockwise as far as they will go (see instructions for the draught
limiter).
6. Start the
exhaust air system
and ramp up to
maximum power
.
7. Using the throttle valve set the
negative pressure to -100Pa
(check with a pressure gauge).
Note: If the negative pressure in the exhaust gas pipe is more than -100 Pa in spite of the throttle
valve being almost closed more draught limiters must first of all be installed.
Set value:
8. Lower the exhaust air system to
minimum power
. The negative pressure in the exhaust gas pipe
should remain at -100 Pa (check with a pressure gauge).
Measured value:
Important:
At minimum exhaust air output in the exhaust air duct there must be a minimum air volume
flow of 50 m

The minimum amounts of air are reached in most exhaust air systems when the minimum speed in
the exhaust air duct does not fall below 1m/s.
Note: The minimum speed in the exhaust air duct depends on the minimum air quantity and the cross
section of the exhaust air. If you have any questions on this please contact your Condair representative.
