1. Introduzione
The TUNAI WP-618H Slim Hanging Filter is a compact and efficient filtration system designed for aquarium fish tanks. It mounts on the rim of your aquarium, providing comprehensive water purification without occupying valuable internal tank space. This filter performs mechanical, chemical, and biological filtration to maintain a healthy aquatic environment.
Its primary purpose is to remove debris, toxins, and harmful substances from the water, contributing to the nitrogen cycle and enhancing oxygenation. This is crucial for the well-being of fish and other aquatic organisms.

4. Istruzioni per l'installazione
- Disimballare: Rimuovere con attenzione tutti i componenti dalla confezione.
- Montare il tubo di aspirazione: Connect the intake tube sections together. Ensure the strainer is attached to the bottom of the intake tube.
- Collegare il tubo di aspirazione: Insert the assembled intake tube into the designated opening on the bottom of the filter unit.
- Filtro di montaggio: Hang the filter unit securely on the rim of your aquarium. Ensure it is level and stable. The intake tube should extend into the water to the desired depth, typically near the bottom of the tank.
- Prime Filter: Before plugging in, fill the filter chamber with aquarium water until it overflows into the tank. This primes the pump and prevents it from running dry.
- Connetti alimentazione: Una volta che il filtro è stato innescato e montato saldamente, collegare il cavo di alimentazione a una presa elettrica adatta.
- Regola la portata: The filter features an adjustable flow rate. Locate the flow adjustment knob (if present) and set it to your desired water flow.

5. Istruzioni per l'uso
Once installed and primed, the TUNAI WP-618H filter will begin operating automatically when plugged in. The filter is designed for continuous operation to maintain optimal water quality.
- Funzionamento continuo: For best results, allow the filter to run 24/7.
- Portata regolabile: Use the flow adjustment mechanism to control the water output. A higher flow rate provides more circulation and filtration, while a lower rate is suitable for tanks with delicate fish or plants.
- Livello dell'acqua: Ensure the aquarium water level remains above the minimum intake level of the filter to prevent the pump from running dry and causing damage.

6. Manutenzione
Regular maintenance is essential for the efficient operation and longevity of your filter. Disconnect power before any maintenance.
- Pulizia/sostituzione del materiale filtrante: The filter media (sponge, carbon, bio-media) should be cleaned or replaced regularly.
- Mechanical Media (Sponge): Rinse the sponge in old aquarium water (not tap water) during water changes to preserve beneficial bacteria. Replace when it becomes too clogged to clean effectively, typically every 1-3 months.
- Supporti chimici (carbone attivo): Sostituire il carbone attivo ogni 2-4 settimane perché si satura e perde efficacia.
- Biological Media: Rinse biological media gently in old aquarium water only if absolutely necessary, to avoid disturbing beneficial bacteria.
- Pulizia della girante: Periodically remove the impeller from the pump housing and clean it with a small brush to remove any debris or mineral buildup that can reduce performance or cause noise.
- Intake Tube Cleaning: Clean the intake tube and strainer to ensure unobstructed water flow.
- Pulizia dello schermo del filtro: The filter screen is designed for easy cleaning. Regularly remove any accumulated debris to maintain optimal flow.
