5. Opsætning
Follow these steps for proper installation of your Tsurumi 12PN pump:
- Placering: Position the pump on a stable, level surface within the pond or water feature. Ensure it is fully submerged and not resting directly on soft sediment. Using a pump stand or elevated platform is recommended to prevent clogging from debris.
- Afladningsforbindelse: Connect a suitable discharge hose or pipe to the pump's 3-inch discharge port. Ensure all connections are secure and watertight to prevent leaks and maintain optimal flow.
- Elektrisk tilslutning: Route the 20-foot power cord safely, avoiding kinks or damage. Connect the pump to a dedicated 115V, grounded electrical outlet protected by a Ground Fault Circuit Interrupter (GFCI). Do not use extension cords unless absolutely necessary and ensure they are rated for outdoor use and the pump's power requirements.
- Indledende kontrol: Before powering on, verify that the pump is fully submerged and all connections are tight.

7. Vedligeholdelse
Regelmæssig vedligeholdelse sikrer optimal ydeevne og forlænger pumpens levetid:
- Afbryd strømmen: Tag altid stikket ud af pumpen, inden du udfører nogen form for vedligeholdelse.
- Clean Impeller and Volute: Periodically remove the pump from the water and inspect the impeller and volute for debris (leaves, algae, small stones). Clean thoroughly with water and a soft brush.
- Tjek strømledningen: Undersøg netledningen for tegn på skader, snit eller flosning. Udskift den, hvis den er beskadiget.
- Vinterisering: In freezing climates, remove the pump from the water before temperatures drop below freezing. Clean it thoroughly and store it in a dry, frost-free location.
