Replacing the Elements
Ensure that the filter is isolated from the compressed air
system and fully depressurised prior to carrying out any
maintenance procedures which are to be done by qualified,
trained authorised personnel only.
1
Unscrew the filter bowls (1) and remove the used elements (2).
Note. We recommend the use of gloves when touching contaminated
elements.
2
Unscrew the automatic drain (3) and fit the replacement. Tighten the
drain to 2.5Nm.
3
Replace the O-rings (4) located in the filter head with the new O-rings
provided.
Ensure to lubricate the O-ring and threads with a suitable
acid free petroleum jelly.
4
Insert the new elements into the filter bowls ensuring that the lugs are
seated correctly in the grooves.
5
Refit the filter bowls and heads ensuring that the threads are fully
engaged and the locking details are aligned.
6
Note: To ensure that the bowl is fully engaged into the head, the 010-030
o
bowl requires 360
of rotation until the thread stop.
7
Attach the element change date label to the filter bowl and write on the
date the element is to be replaced. i.e 12 months after element change.
Note. Do not use solvents or alcohol to clean the labels as this could
cause damage.
8
Slowly open the upstream valves to pressurise the filter, followed by the
downstream valves to pressurise the system.
9
Discard used items in accordance with local regulations.
10 Repeat these procedures for all filters.
11 Re pressurise the unit.
Do not open the valves rapidly, or subject the filter to
excessive pressure differential, as damage may occur.
