Oase FiltoClear UVC Pond Filter System

Unit Configuration and Function Description

The Oase FiltoClear UVC is a pressure filter designed for pond water clarification. It utilizes a multi-stage cleaning process involving foam filters and a UV-C lamp to remove both mechanical and biological impurities.

Unit Components: The unit consists of a housing containing various cleaning stages. Key components include:

• Foam filters (blue for coarse, red for fine)
• UV-C lamp housing
• Inlet and outlet connections
• Soiled water drain
• Function switch

Function Description:

• Cleaning Stage "Filtering": Water flows through foam filters, trapping mechanical soiling. Beneficial bacteria colonize the filters, providing biological cleaning, most effective above 50°F (10°C).
• Cleaning Stage "Radiation": Water is exposed to UV-C light, which kills green algae and pathogenic agents. A bypass feature ensures adequate radiation duration even at high flow rates.

Filter Starter: Optimal biological cleaning is achieved after several weeks. The establishment of a bacterial community on the foam filters can be accelerated by using a filter starter product (not included).

OASE Recommendations:

• Fish population: Approximately 2 ft (60 cm) of fish length per 260 gal (1 m³) of pond water.
• Pond pump compatibility: FiltoClear 3000 (max. 2100 GPH / 8000 l/h), FiltoClear 4000 (max. 2600 GPH / 10000 l/h), FiltoClear 8000 (max. 4200 GPH / 16000 l/h).

Symbols on the Unit:

• Warning Symbols: Indicate potential risks such as personal injury from incorrect use or UV radiation. Always read instructions before use.
• IP 24 Rating: Indicates protection against touching dangerous components and protection against splash water.
• Other Symbols: Indicate protection from direct sun radiation and the need to dismantle at temperatures of 32°F (0°C) and below.

Installation

General Installation Guidelines:

• Maintain a minimum spacing of 6.6 ft (2 m) between the unit and the water.
• Avoid direct sun exposure for the unit.
• Route the return hose so that clean water is returned indirectly to the pond, e.g., through a waterfall, to enhance oxygen enrichment.
• Maximum height difference between the filter lid and water return point is 6.6 ft (2 m).

Installation Possibilities:

• Possibility 1: Bury close to the pond. Dig a hole and place the container up to the mark.
• Possibility 2: Placement close to the pond. Position the unit on firm, level ground where it is protected from flooding.

Connecting a Filter Pump:

• A filter pump is required. Connect only using pressure hoses approved for at least 2.9 psi (0.2 bar) or the maximum pump pressure.
• Hoses with an internal diameter of 1 1/2" or 2" can be connected. 2" hoses are recommended for minimal pressure loss.
• If using a filter starter, add it to the container before proceeding with installation steps.
