Setting Up Procedure; Fittings Assembling - Newa NKF 250 Manual De Instrucciones

10. Install the baskets unit cover back. Make sure that after the installation the cover bore matches the opening of the first
basket. If otherwise, turn over the cover (fig. 9).
11. Install the rotor unit. Make sure that the internal connective cylinder enters the baskets unit cover bore (fig. 10).
Note: From above of the filter case, the reassembly operation seems to be quite easy, if you take into account the fact that the
filter start hold-down device, located on the top of the rotor unit, is in alignment with the internal connective cylinder (fig. 11).
12. ATTENTION: Before you click-up the clips, make sure that the filtering materials are in their proper places, the containers with
the filtering materials are properly placed (the materials do not overlap the edges), and the baskets unit cover is installed in its
proper position.
13. Fit every of the four clips with the corresponding couplings on the rotor unit to the filter case, and attach the rotor unit to the
filter case, with firm pressure on the projecting parts of the clips (fig. 12).

a) Fittings assembling
I. Open NEWA Kanist package, take out the box with the external filter accessories, and place the accessories on the table, as
shown in the figure (fig. 1). Assemble the inlet block, connecting the prefilter grid (d) with the connecting tube (c), and then
with the U-shaped inlet nozzle (b). It is crucially important to ensure correct assembling of these two components, with a force
enough to overcome the resistance of two О-shaped gaskets, so that the suction tube tightly fits the inlet nozzle (fig. 13). To
facilitate the operation, it is recommended to moisten the О-shaped gaskets. If necessary, position of the suction tube can be
regulated by moving it downwards to the first gasket level. To provide a more efficient operation, make sure that the pre-filter
grid (d) is at a distance of 4-5 cm from the bottom of the aquarium. If the connecting pipe (c) is too long, cut it with a saw.
Note: position the suction tube away from aerators or skimmers, since the air emitted by them would reduce the efficiency of
the external filter.
II. Assemble the outlet block, connecting the U-shaped outlet nozzle (e) with the reducing tube (f), and then with the elbowed
coupling with 2 outlets (g). If necessary, you can reduce the length of the outlet nozzle by cutting it with a saw, with respect to
the grooves arrangement (fig. 14). Applying a slight force, put the swing-arm diffusors on the elbowed coupling (g), choosing
between the gooseneck swing-arm diffusers and the swing-arm diffusers for injectors (j). If you decide to use only one outlet of
the elbowed coupling, it is recommended to close the unused outlet with the elbowed coupling plug (h). Note: to ensure better
circulation of water through the gooseneck swing-arm diffusers, it is recommended to place them just below the surface of the
water or at most at the same level.
III. The injectors can be connected through the reducing tube (k), or can be used separately (fig. 15). In any case, they must
be connected with the corresponding diffuser (j). To ensure the correct use, it is recommended to close the injector outlet with
the corresponding stubs (m) from the supply package. Note: to ensure better circulation of water through the injectors, it is
recommended to place them just above the water surface.
