The iSpring WSP-ARB is a reusable spin-down sediment water filter designed to protect downstream terminal equipment and appliances from various water pollutants. This pre-filter system is intended for central water purification, safeguarding items such as pipelines, water purifiers, water heaters, wall-hung boilers, washing machines, and showerheads. Its primary function is to filter out particulate impurities, sediment, rust, floating objects, and other contaminants from the water supply.
One of the key usage features of the WSP-ARB is its integrated auto flushing module, which includes a scraper. This mechanism effectively traps all kinds of impurities without requiring the user to remove the filter, simplifying the cleaning process. The system is designed to be flushable and reusable, contributing to its longevity and cost-effectiveness. A convenient toggle switch allows trapped particles to be flushed out without the need to shut down the water supply first, ensuring continuous water availability during maintenance. The special explosion-proof transparent housing provides clear visibility, making it intuitive and convenient for users to monitor the filter's condition and the amount of contaminant buildup.
The core components of the iSpring WSP-ARB are constructed from highly pressure-resistant, safe, and reliable materials, ensuring durability and consistent performance. The high-capacity system utilizes a 316L food-grade stainless steel precision filter mesh, which is crucial for effective filtration. Unique cleaning features allow for the convenient removal of contaminant buildup from the filter housing with just a few turns of the scraper knob. This design minimizes the effort required for routine cleaning.
For installation, the unit comes with universal fittings, making it easily adaptable to various plumbing sizes and other applications. It offers two types of threads on both ends: 1 inch FNPT and 3/4 inch Push-Fit Plumber Fitting, providing flexibility for different setups. Users are advised to pay close attention to the water flow direction indicated by an arrow on the valve body to ensure proper installation, aligning it with the pipeline's flow direction. Before installation, the main inlet valve should be closed, and remaining water drained from the pipe. After installation, the filter housing assembly must be kept upright. For PPR pipeline installations, firm welding with special welding equipment is required. It is crucial to apply plumber's tape evenly and ensure that other parts do not turn when tightening the hex nut with a wrench. After the filter is installed, a check for any water leakage at the joints is recommended.
Regarding maintenance, the system should be installed in a dry indoor environment, away from heat sources, direct sunlight, fuel oils, and chemicals. It is suitable only for municipal tap water within a specific temperature range and should not be used with wastewater or corrosive liquids. A reliable drainage system must be available at the installation location, or a suitable container should be used to collect the flushed drain water.
After installation, the inlet water main valve should be opened to allow water flow into the filter. To flush the drain, the drain valve knob can be turned. If the optional auto flushing module is present, pressing the on/off button and then the "drain" button will initiate the flushing process. To clean the filter mesh, the scraper knob should be turned clockwise or counterclockwise 3 to 4 times while draining the water. It is recommended to flush the filter at least once a week for 30 seconds, with the frequency depending on the quality of the incoming water.
For more thorough cleaning after 8-12 months of continuous use, the stainless steel filter mesh can be removed and cleaned with a brush or by soaking it in vinegar. For optimal results, professional cleaning is recommended. If normal scraping or rinsing does not remove buildup, the filter assembly should be removed. To do this, the filter housing is unscrewed counterclockwise using the included wrench, and the filter assembly is then removed and cleaned. It's important to note that the scraping assembly does not need to be removed if only the filter assembly is being cleaned.
When reinstalling, the scraping assembly is inserted into the filter housing by aligning the quadrilateral hole with rounded corners into the hexagonal hole on the bottom of the filter housing. For the filter assembly, the four 'bumps' inside the scraper assembly must align with the four grooves on the upper filter housing before insertion.
The iSpring WSP-ARB is designed to be a user-friendly and effective pre-filtration solution, emphasizing ease of maintenance and reliable performance to extend the life of household appliances and improve overall water quality.
