7.4. Maintenance of the control assembly and intake/outlet system
Checking and cleaning the intake/outlet system and the control assembly (3) is not necessary in each maintenance cycle.
Nevertheless when these elements are visibly soiled, they should be cleaned under filter maintenance.
After unscrewing the clamp bolt (30) – see figure 12 – remove the intake/outlet system from the water, place the entire
unit disconnected from the filter according to figure 18 in larger vessel and move to a place where it will be possible to
wash the entire assembly. Remove the hoses (1) from the control assembly (3) and disassemble the water intake and
outlet endings (shown on figure 17), then wash all of the elements under running water.
CAUTION: The control assembly (3) must not be disassembled. To clean the intake and outlet canals proceed according
to the instructions next to figures 24 and 25.
Fig. 24 – 25. The bottom part of the control assembly (3) has a rotating disc "T" with two large openings. In position
marked on figure 24 these openings are closed, there is no passage. That is the position of disconnecting the control
assembly from the filter cover (4) according to picture 18. A characteristic feature of this position is that the cut "E" of the
disc "T" is directly over the cut "D" of the control assembly body (3). Turn the disc "T" anticlockwise into a position where
the passages of intake and outlet are open. The open condition is shown on figure 25. In this position it is visible that the
cut "E" of the disc "T" is moved away from the cut "D" of the body. In this position of disc "T" the entire intake/outlet system
can be cleaned under running water, even without disconnecting the elastic conduits (1), or, what is recommended, after
removing them. [That condition is shown on the figures].
The disc "T" should be turned a little further so that the small stub "F" – visible on figure 24 – is placed over one of the
openings of intake or outlet. Check the flow capacity of the hose.
The gasket (12) should be removed from the body, it should be cleaned together with its groove on the body. Place the
gasket back in its groove and lightly lubricate with Vaseline.
Turn the disc "T" back to the position shown on figure 24, where the cut "E" will be placed again over the cut "D" – in a way
described above, and both of the large openings in disc "T" will be completely closed.
The control assembly (3), placed in a position according to figure 24, can now be placed back in its socket in the filter cover
(4), in reverse order to the one of figure 18. To do this place the assembly (3) on the cover (4) in a position, where aligned
cuts "D" and "E" of the control assembly will be directly over the protrusion "C" visible in the cover socket and shown on the
figure 23. In this position the assembly (3) should be vigorously pushed into the cover (4) socket until resistance. After this
operation the stub "F" – see figure 24 – will tightly contact the gasket (13) – see figure 23 – and create a part of the internal
canal used for the initial pumping according to subsection 6.1.
CAUTION: In other position of the disc "T" and in other position of the control assembly (3) its insertion will be impos-
sible. The attempt to force improperly aligned control assembly into its place might cause the destruction of the control
assembly or the filter cover (4).
Turn the control assembly (3) inserted until resistance into its original position, shown e.g. on figure 13.
After completing the cleaning, elements of intake/outlet systems should be reassembled in reverse order, according to
subsection 5.4.
7.5. Maintenance of the UV Sterilizer (only in FZKN 150 PLUS and 250 PLUS types)
In order to maintain the effective operation of the UV sterilizer the quartz casing (34) should be cleaned on a regular basis.
Under filter maintenance, to clean the container (10) conveniently, the UV sterilizer should be removed [we have already
mentioned it in subsection 7.2, after the comment for figure 20]. It is possible once the water was has been poured out of the
container and all of the magazines (7) with filtration media have already been removed.
Fig. 26. From the outside, from the bottom of the container (10) side remove the quartz casing (34) from the sterilizer
housing (33) by turning it anticlockwise according to the arrow described "OUT". Along with it the complete fitting (36)
and UV fluorescent lamp (35) will come out. Wipe the quartz casing (34) dry with a soft cloth from the outside.
Remove the gasket (24) – see figure 28 – clean the gasket and its groove, insert it back into the groove, lightly lubricate
with Vaseline and set aside.
From the inside of the filter remove the sterilizer housing (33) in reverse order to the one described at figure 6. In order to
do this the flow cover (9) should be slightly raised, then the housing (33) should be screwed out clockwise. Remove the
flow cover (9) in reverse order to the one described at figure 5.
Clean the flow cover (9) and the sterilizer housing (33) from the inside and outside.
