Operating
•
Be sure that the filter housing and drain are tightly closed. Open the valve on the
inlet side of the strainer. Slowly open the valve on the outlet side of the filter. The
filter is now in service.
•
Filtration start as soon as flow is steady through the filter. As the filter removes dirt
from the air, the accumulated dirt causes a resistance to flow. As a result, the gauge
pressure will rise and the flow will decrease.
•
When the pressure rises to
(see the parameters about differential pressure in a
technical data given attached to the filter elements)
above the starting pressure or
when the flow decreases below the desired rate, clean or replace the filter element.
•
Once your filter is running and there is a pressure reading, line up the green arrow
with the current reading. When the pressure rises to or above the red or second
arrow, it is time to clean or replace your filter elements.
•
If to much air pressure is applied to the filter, you may burst the filter elements. You
can hear change the sound of the pump when it is working. In technical data is stated
a maximun allowed pressure, if this value of pressure is achieved, you must to
replace the filter elements.
•
Condensate should be drain regularly, for install and operating the drain condensate
device see instruction for operating, which are attached to the device.
Maintenance
HAZARD
due to a sudden release of pressure!
Never remove any parts of the filter, for as long as the filter is still pressurized!
Depressurize the filter before carrying out any work on the filter.
DANGER
due to the release of a critical gas!
The release of a critical (Fluid group 1) gas from the network can constitute a
considerable risk for man and environment. Therefore heed the following before
working on filters for critical gases:
•
flush the pipe section in question with inert gas
•
have the notes on hazardous substances for the used gas ready
•
take appropriate protection measures
WARNING
due to the hot touch surfaces!
The gaseous fluid flowing through the filter could have a temperature up to
120
°C/
248
°F.
Do not touch hot surfaces!
Wear safety gloves if applicable.
WARNING
: internal corrosion can seriously reduce the safety of installation!
Check it during changing the cartridge.
