Correct electrical installation
− Electrical installations must meet the national regulations and may only be carried out by a qualified electrician.
− A person is regarded as a qualified electrician, if, due to his/her vocational education, knowledge and experience, he
or she is capable of and authorised to judge and carry out the work commissioned to him/her. This also includes the
recognition of possible hazards and the adherence to the pertinent regional and national standards, rules and regulations.
− For your own safety, please consult a qualified electrician.
− The unit may only be connected when the electrical data of the unit and the power supply coincide. The unit data is
to be found on the unit type plate or on the packaging, or in this manual.
− Ensure that the unit is fused for a rated fault current of max. 30 mA by means of a fault current protection device.
− Extension cables and power distributors (e. g. outlet strips) must be suitable for outdoor use.
− Ensure that the power connection cable cross section is not smaller than that of the rubber sheath with the identifi-
cation H05RN-F. Extension cables must meet DIN VDE 0620.
− Protect the plug connections from moisture.
− Only plug the unit into a correctly fitted socket.
Safe operation
− Never operate the unit if either the electrical cables or the housing are defective!
− Do not carry or pull the unit by its electrical cable.
− Route cords/hoses/lines in a way that they are protected against damage, and ensure that they do not present a
tripping obstacle.
− Only open the unit housing or its attendant components, when this is explicitly required in the operating instructions.
− Only execute work on the unit that is described in this manual. If problems cannot be overcome, please contact an
authorised customer service point or, when in doubt, the manufacturer.
− Only use original spare parts and accessories for the unit.
− Never carry out technical modifications to the unit.
− Only operate the unit if no persons are in the water!
− Keep the socket and power plug dry.
Installation
Filtral 3000
Connecting the hose (Fig. A)
Screw the bend (12) on the connection thread of the UVC water housing (26) including the washer (14). If necessary,
shorten the stepped hose adapter (16), screw on the bend (12) and fit the hose.
Filtral 6000/9000
Connecting the venting pump – option (Fig. S-V)
If you wish to enrich the water with additional oxygen, connect the venting pump (Aqua Oxy) prior to installing the unit.
The Aqua Oxy scope of delivery includes the aeration stone and the hose.
Open the filter housing (Fig. S): Pull the clamps on both sides of the bottom strainer casing (2) to the side and lift off
the top strainer casing (1). Remove the foam filter (3).
Connect the aeration stone (Fig. U): Inside the housing, connect the aeration stone (25) with a section of the hose (4)
to the air connector (5) and place the aeration stone (25) between the gravel bags (24). Ensure that the hose is not
kinked. Connect the aeration pump (Aqua Oxy) to the air connector (5) outside of the housing. Read the aeration pump
documentation.
Close the filter housing (Fig. V): Place the foam filter (3) in the bottom strainer casing (2). Attach the top strainer casing
(1) and press it onto the bottom strainer casing (2) until the clamps engage in the bottom strainer casing.
Important: Lead the connection cable (7) through the cable opening in the bottom strainer casing (2) and route the
cable such that pinching is avoided.
Connecting the hose (Fig. A)
Screw the bend (12) on the connection thread of the UVC water housing (26) including the washer (14). If necessary,
shorten the stepped hose adapter (16), screw on the bend (12) and fit the hose.
