b) Connection of the shutoff valve with taps INLET - OUTLET with the external filter
ATTENTION: to prevent water leakage and to ensure the proper functioning of the NEWA Kanist external filter, it
is necessary to carry out this operation carefully, strictly observing the instructions below.
I. Make sure that the green mounting nuts, located on the free edges of the inlet and outlet blocks, as well as the nuts on the
shutoff valve with taps INLET – OUTLET are completely eased off (free threaded part – fig. 16).

II. Connect each flexible tube from the supply package to the free edges of the inlet block (b) and outlet block (e), respectively,
tightening them by force, until the tube tip touches the threaded part, into which the green mounting nuts are installed (about
2.5 cm) (fig. 17). Turn the nuts clockwise to securely fix the flexible tube without forcing tightening.
III. Insert the inlet and outlet blocks into the aquarium, placing them transversally to the corresponding joints (b - e) on the
aquarium walls. Fix the inlet and outlet blocks with clamps with suction caps, installing one clamp inside, and the other one
outside of the aquarium for each of two blocks (fig. 18). Note: it is recommended to maintain some distance between the inlet
and outlet to facilitate the proper circulation of water.
IV. Place NEWA Kanist filter in a position previously selected, considering the possibility of being easily operated for the normal
maintenance operations.
V. Connect the shutoff valve with taps INLET – OUTLET to NEWA Kanist filter. Make sure that the former tightly fits the filter rotor
unit. Taking into account the importance of this operation, it is recommended:
a. Close the shutoff valve, by pulling the green lever located between the two taps and raising it up to the full attainment of its
end position. The green lever will be in a vertical position relative to the plane in which it is housed (fig. 19).
b. Insert the shutoff valve into the corresponding grooves in the filter head, pressing down firmly on the outer corners placed
alongside of valves (fig. 20). Make sure that the shutoff valve is properly assembled, checking that there are no gaps between
the valve edges and the filter head.
c. Open the shutoff valve, by pulling the green lever up to the stop. The green lever will be in a horizontal position relative to the
plane in which it is housed (fig. 21).
VI. Cut off the excessive parts of the flexible tubes to provide the correct operation of the filter. This will allow for a water route as
direct as possible and avoid possible bend of the flexible tubes (fig. 22).
VII. In accordance with the arrows on the inlet and outlet nozzles, and inscriptions IN and OUT on the shutoff valve, connect the
flexible tube, installed on the outlet block (upward arrow) to the tap with the inscription OUT. Connect the flexible tube installed
on the inlet block to the tap with the inscription IN. Tighten by force, until the tube tip touches the threaded part, into which
the green mounting nuts are installed (about 2.5 cm) (fig. 23). Turn the nuts counter clockwise to securely fix the flexible tube
without forcing tightening (fig. 24).

FILTER START

a) Location:
NEWA Kanist external filter is a gravity filter, therefore it is recommended to place it in the previously identified position before
connecting the block, which closes the shutoff valve and flexible tubes. An ideal location for the installation of the filter is under
the aquarium on the appropriate furniture.
NOTE: The distance between the water level in the aquarium and the bottom of the filter case must not exceed
150 cm. ATTENTION: DO NOT INSTALL THE FILTER ABOVE THE WATER LEVEL.
b) Actuation:
NEWA Kanist is equipped with an integrated starting system, which actuates the filter by pressing the START button. Therefore,
strictly follow the steps stated below:
I. Make sure that the operations for connection of the shutoff valve with the taps INLET – OUTLET to the external filter have been
carried out in conformity with the instructions (see Section "SETTING-UP PROCEDURE", point b).
II. Repeatedly press START button (fig. 25), until water starts to enter the filter case by gravity. As the filter is filled with water,
the air present in it will be released through the outlet block, producing bubbles.
III. Once all the hydraulic system will be saturated with water (the bubbles do not come out of the outlet block any more), it is
possible to connect the external filter to the power supply. The water will then exit out of the diffusers or injectors in continuous
flow. Disconnect the filter plug from the power supply and repeat the starting procedure.
Note: At the start of the filter, the presence of air remained trapped in the filter material may generate noise, which is considered
normal. The total elimination of air will occur after a few hours allowing the filter to work in utmost silence.

ATTENTION: DO NOT CONNECT THE FILTER PLUG TO THE POWER SUPPLY UNTIL THE UNIT IS FILLED WITH WATER, AS IT
MAY CAUSE DAMAGE OF THE ROTOR.
ATTENTION: DO NOT PLACE THE AERATOR DRIPSTONES CLOSE TO THE INLET BLOCK, AS IT MAY IMPEDE THE EFFICIENT
FILTER OPERATION AND GENERATE NOISE.

MAINTENANCE

ATTENTION: REMOVE ALL ELECTRICAL APPLIANCES IN THE AQUARIUM BEFORE CARRYING OUT INSTALLATION AND
MAINTENANCE OPERATIONS. IN CASE OF MOISTURE INGRESS TO THE PLUG OR ELECTRICAL SOCKET, BREAK THE
NETWORK MAIN SWITCH, PRIOR TO DISCONNECTION OF THE SUPPLY CABLE.
Perform any maintenance operations when the filter is switched off, strictly observing the following instructions
1. Disconnect the filter from the power supply.
2. Close the shutoff valve, by pulling the green lever located between the two taps and raising it up to the full attainment of its
end position. The green lever will be in a vertical position relative to the plane in which it is housed (fig. 26).
ATTENTION: During the maintenance operations, the shutoff valve must ALWAYS be connected to the flexible
tubes in a closed position.
3. Disconnect the shutoff valve from NEWA Kanist filter, pulling taps INLET – OUTLET upwards. It is not necessary to take out
the flexible tubes and the outlet blocks from the aquarium, unless they must be cleaned. In this case, remove the possible
incrustation with brushes.
ATTENTION: It is recommended to provide an absorbing material, necessary for wrapping the shutoff valve, because water may
leak out of it during the disconnection.
4. Lift the filter by the grooves located around its perimeter and move to a suitable place for maintenance (for example, a basin,
a sink, a bathtub, etc.), keeping it upright to prevent leakage. Do not grab the filter for the side levers for opening / closing.
5. For detailed instructions on opening the filter, its containers with the filtering materials, and the reassembly of NEWA Kanist
filter, refer to the section "INSTALLATION OF THE FILTERING MATERIALS".
ATTENTION: to facilitate the maintenance operations, it is recommended to drain the remaining water, holding the baskets,
after the rotor unit removal.
6. When the maintenance operations are finished (see: points a) and b)), connect the shutoff valve with taps INLET – OUTLET to
NEWA Kanist filter. Make sure that the former tightly fits the filter rotor unit. Open the shutoff valve, by pulling the green lever
(see also "Connection of the shutoff valve with taps INLET – OUTLET with the external filter").
7. Put the filter into operation, strictly observing the instructions, stated in Section "FILTER START" (point b – Actuation).
Note: it is recommended to periodically lubricate all the rubber parts of the rotor unit applying vaseline oil on the
O-shaped gaskets, the plunger, the pushbutton pad and the 4 gaskets of shut-off valve.
a) Maintenance of the impeller:
ATTENTION: the impeller used in NEWA Kanist filters consists of supports and ceramic shaft. It is recommended to
be very careful in its handling during the maintenance operations.
1. Remove the impeller chamber cover (4) from the rotor unit (1), by turning it counter clockwise using the appropriate levers
and gently pull it upwards (fig. 27).
2. Disconnect the ceramic shaft and black rubber support from the impeller cover, and carefully put them on the table. Note: the
second rubber support may remain in place within the housing of the rotor: to extract it is necessary to insert the free end of the
ceramic shaft into the rubber support tag, after the removal of the rotor unit.
3. Take out the rotor group from the cylinder, holding the impeller blades, and rinse the rotor group together with the impeller
cover under running water with non-abrasive brush to remove dirt. In case, the rotor unit is covered with calcium plaque, soak it
in vinegar for 15-20 minutes before cleaning, then rinse thoroughly.
ATTENTION: do not use acids or solutions different from normal vinegar, as they may be toxic to fish.
4. Reassemble the rotor unit: first, insert the ceramic shaft, and then install corresponding black rubber supports on the free end
of the shaft (fig. 28).
5. Install the rotor unit back into the cylinder and install the impeller cover, so that the rubber gasket on the ceramic is correctly
positioned in the impeller cover grooves.
6. Fix the impeller cover on the rotor unit, turning the corresponding levers clockwise.
