3.3 INLET CONDENSATE DRAIN
● The condensate is discharged at the same pressure of the air entering the dryer.
● Never point the condensate drain jet towards anybody.
Connect and properly fasten the condensate drain to a collecting plant or container.
● The drain cannot be connected to pressurised systems.
● Do not dispose of condensate in the environment.
● The condensate collected in the dryer contains oil particles released in the air by the
compressor. Dispose the condensate in compliance with local rules.
● We suggest installing a water-oil separator which can be used to convey all the condensate
drain coming from compressors, dryers, tanks, filters, etc.
3.4 QUALIFIED SERVICE PERSONNEL
A) Maintenance and repairs should only be performed by DHL when the air
dryer is shut down and depressurized and when the main power switch is
turned off.
B) Use only the appropriate tools for maintenance and repair.
C) Before dismantling a part under pressure, disconnect the pressure sources
and depressurize the system.
D) Proceed carefully during maintenance and repair. Prevent dirt from
entering by covering parts and orifices with a clean cloth, paper or tape.
A receiver should never be welded or modified in any way.
E) Never leave tools, loose parts or cleaning rags in or on the air dryer.
F) Before returning the dryer into service, check the setting of the control and
safety devices as well as the pressure and the temperature of the
compressed air circuit.
