For any maintenance please note the following warnings:
During the replacement of any fi lter element, ensure the perfect closing
Maintenance Interval
of the fi lter, checking the correct alignment of symbols on the head and
(standard operating
conditions)
the housing.
!
DANGER: A misalignment of these, could result in the expulsion of
the housing during pressurization of the system, with the consequence
of projection hazard of bodies against persons of things.
!
DANGER MACHINE UNDER TENSION
Not perform maintenance while the machine is under tension or under
pressure.
Do not remove any covers of the dryer.
!
DANGER HAZARDOUS VOLTAGE!
!
DANGER MACHINE UNDER PRESSURE
! Not perform maintenance while the machine is under pressure, perform
the following action:
1) Depressurize the compressed air system;
2) Make sure that the pressure on both gauges = 0 bar (n°35)
!
Warning: the dryer is still under pressure in the
"AIR OUTLET SIDE" of the cooler
3) Depressurize the dryer using a valve- "air out cooler"
(if installed by the user) or use the drain-valve of the
dust-fi lter (n°31).
4) Make sure that the pressure on gauge = 0 bar (n°35).
!
The desiccant vessels are designed (EN 13445-3) for fatigue
operation with continuous cycles of loading and unloading for a
maximum period of 20 years.
