5. Instruccions de funcionament

Un cop instal·lada la bomba, seguiu aquests passos per al seu funcionament:

Open RV Waste Valve: Open the black water tank valve on your RV.
Activar la bomba: Turn on the macerator pump using the power switch on the cable. The pump will begin to draw and macerate the waste. Monitor the transparent tube to observe flow.
Rinse Tank (Optional but Recommended): Once the black tank is empty (indicated by clear flow in the transparent tube or reduced pump noise), close the black tank valve. Open the gray water tank valve to flush the pump and discharge hose with gray water. Alternatively, use the rinse water connection on the pump to flush the black tank with fresh water while the pump is running.
Complete Drainage: After flushing, allow the pump to run until the discharge is clear.
Apagar: Turn off the pump, then close all RV waste valves. Disconnect the discharge hose and power.

Important: Do not run the pump dry for more than a few seconds. The pump is equipped with thermal protection to prevent damage from overheating, but continuous dry running should be avoided.

6. Manteniment

Regular maintenance ensures optimal performance and longevity of your macerator pump:

Rinsing After Use: Always rinse the pump and hoses thoroughly with fresh water after each use, especially after processing black water. This prevents residue buildup and odors.
Inspecció de la fulla: Periodically inspect the macerator blades for any signs of wear or damage. While designed for durability, foreign objects can cause issues.
Seal and O-ring Check: Inspect all seals and O-rings for cracks or wear. Replace if necessary to prevent leaks. A spare O-ring is included in your kit.
Emmagatzematge: After cleaning, disconnect all hoses and store the pump and accessories in the provided durable storage case in a dry, cool place.
