4. Configuració i instal·lació
Follow these steps to properly install your skimmer:
- Desembalatge i inspecció: Traieu amb cura tots els components de l'embalatge i comproveu si hi ha algun dany.
- Assemble Skimmer: The skimmer typically comes pre-assembled. Ensure the collection cup is securely seated on the main body. Verify that the air hose is properly connected to the pump's air intake and the air silencer.
- Muntatge: The skimmer uses a magnet holder for attachment. Place the skimmer inside the aquarium or sump at the desired location. Position the external magnet on the outside of the glass, aligning it with the internal magnet on the skimmer body. Ensure a secure grip.
- Nivell d'aigua: The skimmer's performance is highly dependent on the water level. Position the skimmer so that the water line in the aquarium or sump is between the minimum and maximum markings indicated on the skimmer body. Adjust the skimmer's height using the magnet holder if necessary.
- Connectar el controlador: Connect the DC motor cable from the skimmer to the controller unit. Then, connect the power supply unit to the controller and plug it into a suitable power outlet.
- Posada en marxa inicial: Upon first start-up, the skimmer may produce micro-bubbles. This is normal during the break-in period, which can last from a few hours to several days. The skimmer will stabilize and begin producing stable foam over time.
5. Instruccions de funcionament
The Tunze Comline DOC Skimmer 9004 DC features a DC motor with a controller for precise adjustment.
- Encès/apagat: Plug in the power supply to turn the skimmer on. Unplug to turn it off.
- Skimmate Production Adjustment: The controller allows you to adjust the pump's output, which directly affects the skimmate consistency.
- Use the knob or buttons on the controller to increase or decrease the pump's power.
- Per wet skimmate (lighter color, more liquid), increase the pump power or raise the skimmer slightly.
- Per dry skimmate (darker color, thicker consistency), decrease the pump power or lower the skimmer slightly.
- Observe the foam head in the neck of the collection cup. It should form a stable column of fine bubbles.
- Collection Cup Cleaning Function: The controller may include a "cup cleaning" or "feed mode" button. Pressing this button typically pauses the skimmer for a set period (e.g., 10 minutes) to allow for collection cup removal and cleaning without overflowing. Press it again to resume normal operation.
6. Manteniment
Regular maintenance ensures optimal performance and extends the lifespan of your skimmer.
- Copa de col·lecció: Empty and clean the collection cup regularly, typically every 1-3 days, or as needed depending on skimmate production. Rinse with fresh water.
- Skimmer Neck: Wipe the inside of the skimmer neck (below the collection cup) weekly to prevent organic buildup, which can hinder foam production.
- Air Silencer and Air Hose: Check the air silencer and air hose periodically for blockages or salt creep. Clean with fresh water and a small brush if necessary.
- Pump and Impeller: Every 1-3 months, or if performance decreases, disassemble the pump and clean the impeller and pump housing. Remove any debris, calcium buildup, or slime. Use a soft brush and vinegar solution for stubborn deposits. Rinse thoroughly with fresh water before reassembly.
- Neteja general: For a more thorough cleaning, the entire skimmer body can be soaked in a vinegar solution to remove stubborn algae and calcium deposits. Rinse thoroughly before returning to the aquarium.
