- Step 5. System Start-up
- Make sure no tubing is kinked. Place a towel under the system to catch any possible water leaks.
- Open the drinking water faucet. Slowly turn on the Feed Water Adapter (AFW43) and check for leaks. The top 3 causes of leaks are 1) The tubing is not fully inserted into the quick-connect fitting. 2) The O-ring is not in the correct place or is kinked...
- Rinse the system for 5-15 minutes. It is normal to see residual carbon and fine air bubbles in the water when flushing the system for the first time.
- Check for leaks daily for the first two weeks after installation to ensure the system is functioning properly.
