•
Isolate dryer from air supply
•
De-pressurize dryer by running dryer and allowing system
pressure to purge to atmosphere. Loss of pilot pressure
will eventually prevent purge/repressurization valves from
opening. Remaining pressure can be vented to
atmosphere through the manual drain on the pilot air
filter. The system must be fully de-pressurized before
removing the bowl.
•
Remove the filter bowl by pushing up, turning
counterclockwise and then pulling straight down.
•
Clean the filter bowl.
•
Replace the element – Pull off the old element and
discard. Make certain o-ring inside top of replacement
element is lubricated and in place and then push element
onto filter head.
•
Clean and lubricate o-ring at top of bowl and reassemble
in reverse order.
NOTE: Wave spring ends should be pointed down to prevent
the wave spring from interfering with reassembly.
