CONTROL SYSTEM
warning
The LEFT and RIGHT buttons are used only by Purex engineers to access a password protected menu. This protected menu
is used to set up the machine during manufacture and therefore should be ignored. If the password protected screen is
accessed in error you can return to the main screen by pressing LEFT and then UP.
Set up
Ensure the fume extractor is connected to the correct electrical supply. Also ensure that the fume extractor is properly
connected to the process before set up.

Adjusting the airflow rate
To adjust the airflow rate press the UP and DOwN buttons together. Both buttons will then
begin to flash (red). To increase the airflow rate press the UP button, to decrease the airflow
rate press the DOwN button. The target airflow measurement is shown on the graphic
display together with the actual airflow being achieved by the fume extractor. Once the target
value has been set, do not touch any other buttons. After a few seconds the buttons will
cease to flash and the set value will be stored.
what airflow rate to set?
In most cases the initial airflow rate will be factory set and only slight adjustment may be necessary on site. The best method
of setting the airflow is by site observation. The lowest possible airflow should be used which still adequately controls/removes
the fumes produced by the process. Please note that setting the flow level unnecessarily high may reduce filter life.
Fully automatic operation
The airflow rate is the only parameter that needs to be set by the operator. The Purex machine will automatically maintain the
airflow level you have set without any further intervention required.
