GCF - Installation and operating manual
Starting up
• Check that the operating data (pressure, temperature and flow-rate) do not exceed
values on the specification plate.
• Close the on-off valve (V1) downstream of the filter, slowly open the on-off valve (V2)
upstream to the filter, and let the gas flow from the manual or automatic drain valve
for a few minutes; close the drain valve and slowly open the on-off valve (V1) down-
line from the filter.
V2
If a filter grade A is installed, check the good efficiency of the pre-filters, otherwise the
presence of any oil and water aerosols make the absorption power of the filter void.
