9.6 Maintenance of in-line filter
The in-line filter where supplied needs to be
cleaned at regular intervals. The frequency
depends on the content and size of debris in the
fluid being filtered. An increase in the pressure
drop over the heat exchanger indicates the need
for cleaning.
Clean the in-line filter in this sequence:
1.
Stop fluid circulation pump.
2.
Close valve on the filter side.
3.
Drain the filter side.
4.
Remove the full-faced gasketed blind
flange on the follower.
5.
Carefully pull out the in-line filter
through the follower.
6.
Clean the filter with water and brush.
Soap which is not damaging the filter
material (AISI 316) may be used.
7.
Before reinserting the in-line filter it is
recommended that you flush any lose
debris from the port where the filter is
installed.
8.
Carefully re-insert the filter in the fluid
inlet port through the follower.
9.
Check that the full–faced gasket is in
place on the blind flange.
10.
Place the blind flange on the follower.
11.
Open the valve on the filter side and
release air.
12.
You may now start your circulation
pump.
