Repairing Inlet/Outlet Connections
A leak may occur at the inlet/outlet connections because of
defective tubing. To repair:
1. Turn off incoming water supply and depressurize system
by removing the filter cartridge(s).
2. Disconnect the water line by pushing the collet squarely
against the face of the fitting.
3. Pull the tubing to release.
4. To repair the connection, cut off at least 3/8" (6.4 mm)
from the end of the tubing. Tubing ends must be cut
square to ensure a positive seal.
5. Refer to notes and instructions under “Installation -
AR-10000/AR-20000/AR-40000” to reconnect the water
line.
