Troubleshooting Guide
Water does not flow from the filter
Check to see if the original water supply valve is open, allowing water to flow to the filter. Also, check for
crimps or sharp bends in tubing. Check maintenance schedule for cartridge change-out.
Water appears cloudy or air comes out of filter faucet
Flush filter to remove any carbon fines or trapped air in the filter and water lines. Longer flushing may be
required to eliminate air bubbles completely. Refer to Performance Data Sheet or Flush Instruction Card for
proper flush time.
4. Test System
A. Open cold water supply valve.
B. The system will pressurize. Check for leaks. If any leaks are present, refer to troubleshooting section.
5. Flush Filter
