Filtration System Overview
Maintaining pristine water quality is crucial for enjoying your Lifesmart hot tub. Your spa utilizes a multi-stage filtration system designed to remove debris and impurities. This system typically includes a filter cartridge, which captures particles as water circulates through the pump. Regular filter cleaning and replacement are essential for optimal performance;
The filtration cycle operates automatically, but you can also initiate it manually through the control panel. A clean filter ensures efficient water circulation and prevents strain on the pump. Ignoring filter maintenance can lead to cloudy water, reduced jet pressure, and potential damage to the spa’s components. Always power off the hot tub before accessing the filter compartment.
Filter Cleaning and Replacement
To clean your Lifesmart hot tub filter, first remove it from the filter compartment after powering down the spa. Use a garden hose with a high-pressure nozzle to spray between the pleats, dislodging dirt and debris. For stubborn buildup, a filter cleaning solution can be used – follow the product instructions carefully. Rinse thoroughly after cleaning.
Filter replacement is necessary approximately every 12-18 months, depending on usage. A clogged or damaged filter significantly reduces water flow and filtration effectiveness. Inspect the filter for tears or wear; if present, replace it immediately. Proper filter maintenance extends the life of your spa and ensures consistently clean, enjoyable water. Refer to your model’s parts list for the correct filter type.
Water Maintenance and Chemical Balancing
Maintaining proper water chemistry is crucial for a safe and enjoyable hot tub experience. Regularly test the water using a test strip or liquid test kit, checking pH, alkalinity, and sanitizer levels. Ideal pH should be between 7.2 and 7.8, and total alkalinity between 80-120 ppm.
