Changing filter element
Necessary Tools: Strap wrench (for opening the union nuts)
Change the filter elements on the flush and return line filters as specified in
the maintenance schedule.
To change the filter element, proceed as follows:
1. Remove the left side panel.
To do this, turn the locks 90° in a
counterclockwise direction using the
four-sided hollow socket key. Flip the
side paneling away from the CTU and up
out of the lower guide.
Remove the ground bond wire to the side
panel.
2. Drain the test liquid from the filter
housing.
To do this, carefully unscrew the drain
plug (2) at the bottom end of the filter
bowl in a clockwise direction using a 6
mm Allen wrench.
The drain plug has ventilation slots.
The filter bowl contains approx. 1.5
liters test liquid.
Catch the test liquid that drains out in a
suitable container and put it in the
analysis chamber after changing the
element.
3. Loosen the coupling nut (1) by turning it
in a clockwise direction and then remove
the filter bowl (2).
Use a strap wrench to remove
the coupling nut.
