All electrical appliances must be connected to an emergency cut-off switch set to 30 mA. Users should verify that the mains voltage matches the product label. This appliance is for indoor use only, with water temperatures not exceeding 35°C. It must not be used with corrosive or abrasive liquids. Before connecting to the mains, check for any damage to the cable or appliance. The power cable cannot be replaced or repaired; if damaged, the entire unit must be replaced. The appliance should not be operated without water to prevent impeller damage. It should only be used for its intended purpose. Disconnect the power cable before handling. Do not handle the power cable or plug with wet hands. If the plug or power socket becomes wet, shut off the mains before disconnecting. Keep the appliance away from heat sources. To prevent water from dripping onto the plug or socket, it is recommended to form a drip loop with the cable below the level of the power socket (Fig A). Do not lift the appliance by its cable.

This appliance can be used by children aged 8 and above, and by persons with reduced physical, sensory, or mental capabilities, or lack of experience and knowledge, provided they are supervised or have been instructed on safe use and understand the associated hazards. Children should not play with the appliance. Cleaning and maintenance should not be performed by children unless they are over 8 and supervised. Keep the appliance and its cord out of reach of children under 8 years.

Electrical Safety Standards for Class II Appliances:

The Class II filter features a twin cable with double insulation and does not require an earthing conductor.

Installation:

Before any aquarium maintenance, disconnect all electrical equipment, both inside and outside the tank. To access the filter media, open the locking clips on the filter body and lift off the pump head (Fig.B). Remove the filter media, rinse them thoroughly under running water, and place them back in their original position (the filter sponge with the hole facing upwards). Do not use soap or detergents.

Assemble the intake and outlet tube fittings separately, connect them to the flexible hoses using the hose lock nuts, and secure the hoses to the inside wall of the tank with the suction cups. The outlet unit can be configured with either the L-shaped fitting or the spray-bar, depending on preference. The spray-bar can be installed at or below water level to adjust oxygenation. Connect the flexible hoses to the intake (IN) and outlet (OUT) units on the pump head, securing them with the hose lock nuts.

Place the pump head onto the filter body, ensuring the locking clips are fully open, then close the clips (Fig. C) to secure it. Verify that it is properly seated. Unscrew the cap of the filter body, fill it with water, and screw the cap back on tightly. Check all connections for watertightness before plugging the filter into the mains. For initial priming, the DF400 must be placed on a flat surface, in a vertical position, next to the aquarium.

Maintenance:

Before any aquarium maintenance, disconnect all electrical equipment, both inside and outside the tank. Open the locking clips and lift off the pump head without disconnecting the flexible hoses. To preserve bacterial colonies, wash or replace only a portion of the filter media at a time. To clean the impeller, remove the two screws from the impeller cover with a Phillips screwdriver, extract the impeller, and rinse it under warm running water. It is recommended to clean the impeller every three months and replace it annually. If necessary, clear any deposits from the intake and outlet units and flexible hoses using a small brush. Do not use soap or detergents. Reassemble the unit in reverse order and restart the filter following the "Installation" instructions.

Installation for DF700, DF800, DF1200, DF1400:

Before any aquarium maintenance, disconnect all electrical equipment, both inside and outside the tank. Open the locking clips on the filter body and lift off the pump head (Fig.B). Remove the cover grid and media containers. Separate the media containers by opening their locking clips with a flat-blade screwdriver or similar tool (Fig.C). Remove the pre-supplied filter media, rinse thoroughly under running water before use. Fill the empty containers with PRODAC INTERNATIONAL filter media: CRYSTALCIL and CLAROCAR (not supplied). Rinse these thoroughly before use. Do not use soap or detergent. Caution: Do not overfill the containers to avoid clogging the flow-through pipe. For optimal filtration, place the media in the containers from bottom to top in the following order:

DF700 and DF1200: CRYSTALCIL, sponge, wool
DF800 and DF1400: CRYSTALCIL, CLAROCAR, sponge, wool If the aquarium is new, add NITRIDAC (not supplied) directly into the filter to activate bacteria. If the aquarium is already set up, add AQUASANA (not supplied) directly into the tank to maintain biological water balance. Close the containers with the locking clips, slide them along the groove into the filter body (Fig. D). Cover the last container with the grid, aligning the hole for the UV light. Connect the strainer to the intake U-tube (Fig. E). If necessary, insert the vertical fitting to the U-tube before the strainer (Fig. F) using a tube connector (Fig.G). Secure the tube to the inside wall of the tank with suction cups. Caution: The strainer must be installed below the minimum water level. Connect the L-shaped fitting to the outlet U-tube using tube connectors, and insert the adjustable diffuser (Fig.H). Alternatively, assemble the spray-bar and its fitting to the desired length and connect to the L-shaped fitting (Fig.I). Caution: The spray-bar can be installed below water level or just above the surface, depending on the desired oxygenation and surface movement. Secure the tube to the tank wall with suction cups. Cut the flexible hoses to the appropriate length to connect them to the intake and outlet U-tubes, ensuring no kinks. Shorten if necessary. Open the closing lever of the IN/OUT unit and lift it off the pump head (Fig.J). Connect the flexible hoses to the intake (IN) and outlet (OUT) units, securing them with the locking nuts (Fig.K). Insert the unit into the pump head and lock it with the lever. Fill the filter body with ¼ water, place the pump head onto the filter body, and lock it with the clips. Caution: The UV lamp cover must fit exactly into the hole of the first media container. Check that the pump head's sealing gasket is properly seated and clean. Place the filter in the desired location. For optimal functioning, the distance between the water surface and the filter base should not exceed 180 cm. Manually operate the priming pump until water reaches the outlet tube (Fig.L). Check all connections for watertightness, then connect the pump head to the mains. After about 30 minutes, when there is no air inside the filter, adjust the flow rate by moving the lever on the IN/OUT unit (Fig.M). Press the lighting button of the UV lamp (Fig. N); an indicator light (Fig. O) will show that the UV lamp is on. All "DF series" external filters must be installed on a flat surface and in an upright position before priming.

Maintenance for DF700, DF800, DF1200, DF1400:

Before any aquarium maintenance, disconnect all electrical equipment, both inside and outside the tank. Pull out the intake and outlet unit (IN/OUT) without disconnecting the flexible hoses. Unlock the pump head by opening the locking clips on the filter body and lift it off. Remove each media container and wash the filter media. Replace wool, sponge, and CLAROCAR every three months, and CRYSTALCIL every six months. To avoid destroying bacterial colonies, wash and replace only a part of the filter media at a time. To clean the impeller, unscrew the two screws from the impeller cover with a Phillips screwdriver (Fig.P), remove the impeller, and rinse it under warm water. It is recommended to clean the impeller every three months and replace it annually. If necessary, clear any deposits from the intake and outlet units and flexible hoses using a small brush. Do not use soap or detergents. Reassemble the unit in reverse order and connect the filter to the mains as described under "Installation".

UV Lamp Replacement:

If the UV lamp indicator light is off, even if the lighting button is on (Fig.Q), the UV lamp is not working and must be replaced. Pull out the pump head, unscrew the black plastic cover of the UV lamp with a Phillips screwdriver (Fig. R). Pull the quartz tube upwards, remove the lamps, and replace them. Reassemble the unit in reverse order. Caution: When reassembling the UV lamp unit, the quartz tube does not fully fit into its housing because it forms a small vacuum that ensures watertightness. Push down the tube cover strongly to fit it tightly. It is suggested to perform this operation with two people (Fig.S).
