Installation and replacement procedure for WSB-1 filter:
1. Close shut off valves before and after filter head. Depressurize filter.
2. Grasp head and cartridge securely, and turn used cartridge slowly to the left. If water line has not been properly depressurized, a small discharge of water may occur. Gently pull cartridge straight out and discard.
3. Align tabs of new cartridge with head and insert new cartridge into head. Turn cartridge to the right until the filter stops.
4. Place the inlet shutoff valves in regular working position. Due to air and carbon fines water may initially run cloudy but will clear. Flush system in accordance with Performance Data sheet.
When to change a filter: There is a replacement indicator light for the water filter cartridge on the dispenser. The filter cartridge should be replaced when the filter light comes on, or every 6 months, or if you notice a decrease in flow of water.
Important: It is essential that operation, maintenance and filter replacement be carried out in accordance with manufacture's recommended procedures and guidelines for this product to perform as advertised. Failure to do so may void warranty
