2. Adjust Flow Rate: This pump features an adjustable flow rate. Locate the flow control switch (if present, typically a small lever or dial) on the pump body and adjust it to achieve the desired water flow.
3. Stop Operation: To turn off the pump, simply unplug the power cord from the electrical outlet.

6. Maintenance

Regular maintenance ensures optimal performance and extends the lifespan of your pump. Always disconnect power before performing any maintenance.

• Cleaning the Impeller: Over time, debris can accumulate around the impeller, reducing pump efficiency. Carefully remove the front cover of the pump (if detachable) and clean the impeller and its housing with a soft brush and clean water.
• Check for Blockages: Periodically inspect the intake vents and discharge nozzle for any blockages from algae, plant matter, or other debris. Clear any obstructions to maintain proper flow.
• Clean Suction Cups: If the suction cups lose their grip, clean them and the surface they attach to. This will help maintain secure placement.
• Winterization (for outdoor use): If used outdoors in freezing temperatures, remove the pump from the water and store it in a frost-free location to prevent damage.
