TROUBLESHOOTING
LEAKS BETWEEN THE SYSTEM HEAD AND THE FILTERS:
1. Turn off the water supply to the lter and dispense water from kitchen faucet until water and
airflow stops.
2. Remove cartridge and inspect o-rings to make sure they are in place and clean.
3. Install cartridge, turn on water supply and check for leaks.
LEAKS AROUND THE FITTINGS:
1. Turn off the water supply to the lter to relieve pressure.
2. While pulling the 1/4˝ plastic tubing with one hand, press in on the grey collar around the inlet and/
or outlet tting. Check to make sure that the 1/4˝ plastic tubing is cut squarely and that it is not
scratched or crimped. If the 1/4˝ plastic tubing is unevenly cut or scratched, cut off 1/2˝ to 5/8˝ and
re-install the tubing.
3. Turn on water supply and check for leaks.
LEAKS ON THE WATER SUPPLY ADAPTER CONNECTION:
1. Turn off the water supply to the lter to relieve pressure.
2. Locate the water supply adapter.
• If the 1/4˝ plastic tubing is leaking, follow the previous steps (“Leaks around the ttings”).
• If the thread between the water supply adapter and the cold water line is leaking,
tighten more securely.
3. Turn on water supply and check for leaks.
If leaks persist, or if there are other leaks on system, turn off water supply. Call technical support
