High-skimming performance is achieved with the innovative honeycomb bubble plate design working in tandem with the needle brush pump and external silencer. The skimmer operates in freshly mixed brine and has a break-in period during which foam may flow out, this is to be expected and will normalize after a brief period. During the use of the needle pump, due to the narrow space between the rotor shaft and the self-rotating chamber, the friction temperature is high. Sediment can adhere to the rotor. Over time, this can aggravate wear and tear. Regular maintenance and cleaning are required. Do not run the water pump idly in an anhydrous state. The normal applicable water level is between 18-22cm (7″ – 8.5″ inches). Please refer to the manual for your specific model.
