Examine and Replace Internal Inline Filters
Inline filters are installed inside the device enclosure (refer
to the following figure).
Figure 13. Location of inline filters
Periodically examine the inline filters inside the device
enclosure for dirt and particulate buildup.
If the inline filters become severely clogged with particles
or
moisture, the flow rate for the
device will decrease and
eventually cause a flow fault.
Replace dirty filters when necessary to prevent damage to
internal components. For a list of ap
proved parts and how
to order them, refer to “Ordering Information,” p. 52.
Do the following procedure to repl
ace the in
line filters:
