After performing the above actions and UV sterilizer maintenance – only in case of

FZKN PLUS

types, see subsection 7.5

– place the filtration cartridges in the container (10), taking into considerations the notes written in subsection 5.3.

Prior to closing the filter you should perform the maintenance of the cover (4) according to subsection 7.3.

7.3. Maintenance of the complete cover – inside: pump

Fig. 21.

Remove the impeller chamber cover (16) with an anticlockwise movement according to the arrow.

CAUTION

: Do not lose the gasket (15) placed in its socket “B”! It is an important element of the self deaerating system

of the filter during its operation.

Remove the impeller (14) and the gasket (15). Clean the removed elements, impeller chamber, outlet pump canal – shown
on the opposite side on figure 23 and the impeller socket. It is recommended to carry out these actions by flushing with
water under pressure (you can use a bathtub shower hose).

CAUTION:

In case of hard deposits on impeller socket walls, impossible to remove with water under pressure, particu-

lar caution must be exercised in cleaning this fragment in order not to break the ceramic axle that cannot be removed.

Remove the main gasket (5) from its socket, clean both the gasket and its socket in the cover (4). Lubricate the gasket with
Vaseline and place it back in its socket.

CAUTION:

The main gasket (5) is not to be stretched!

Check the permeability of internal tube under point “B”. It is a part of internal deaerating canal (its length is ca. 8 centim-
eters).

Fig. 22.

Check the permeability of internal deaerating canal in the impeller chamber cover (16) between the points “X” and

“Y” (marked on the figure with narrow arrows) under a stream of water.

Fig. 23.

On the top side of the cover (4) clean the control assembly socket and – in its bottom – all of the openings includ-

ing the intake opening IN and outlet opening OUT. By removing the special gasket (13), under a stream of water and
pulling on the start pump “P” several times the space over the pump “P” can be washed.

When cleaning this socket particular attention should be paid not to damage the lateral cylindrical surface, as the smooth
surface is important to ensure proper tightness of the seal (12) mounted on the control assembly (3) – see e.g. figure 25.

CAUTION

•

The proper placement of the gasket (13) is important for the reassembly: opening in the gasket (13) should be placed

closer to the axis of rotation of the control assembly (3).

•

Do not scrape! For cleaning use only a soft brush or cloth and lukewarm water with a mild cleaning agent without

detergents. In case of hard deposits a mild scale removal solution can be used as well. When finished cleaning it is
necessary to rinse in clean water.

Reassembly the pump in reverse order, not forgetting about putting back the gasket (15). Screw the impeller chamber
cover (16) clockwise

until resistance

– see figure 10.

CAUTION:

•

After putting the impeller (14) on axle it should turn with no resistance.

•

The cover must not be disassembled any further. Any unauthorized attempt of removing the pump assembly from

the cover (4) will result in loss of warranty. Performance of possible further repair actions, not described in this chapter
should be entrusted to the manufacturer’s service.

Close the filter according to the description at the end of subsection 5.3.

Return with the filter to the aquarium and place the control assembly (3) in its socket in the cover (4), in reverse order to
the one described next to figure 18.

If there is any difficulty with placing the control assembly in its socket it is recommended to read subsection 7.4 and pay
special attention to figures 24 and 25, where this operation is described in detail.

Install the

temporary system

of intake elements in place of the normal system according to figure 15.

To start the filter the actions described in section 6 have to be performed.
