Theamountofcondensatedependsontheoperatingconditionsoftheunitand
the humidity of the air.
Open the manual drain valve from time to time to remove eventual impurities (see
alsosectionPreventiveMaintenanceschedule).
3. Onreceivermountedcompressors,openthemanualdrainvalveoftheairreceiver
regularly to remove the water (specially in case of compressors without dryer). See
alsosectionPreventiveMaintenanceschedule).
NOTICE!
The dew point will deviate from nominal when the nominal conditions are exceeded.
If the dew point remains too high or unstable, consult section Problem solving.
