Prepare Tubing
Notice:
Make your cuts against a flat cutting surface with a razor blade, or use a tube cutter. Tubing
cuts must be perfectly straight or the tube may fail to lock into fittings and cause leaking.
When cutting tube lengths, it is important to ensure the
system is accessible for maintenance. During installation
and measuring, it is recommended to complete all of the
tubing connections to the system with the system in front of
the cabinet (before mounting) to allow enough slack for
easy removal of the system for easier maintenance.
Measure and cut (4) lengths of tubing in the appropriate
lengths for:
Feed line (cold water) to system pre-filter inlet
(White Tube)
Post filter inlet (tee) to tank
(Blue Tube)
Alkaline filter outlet (elbow) to faucet
(Blue Tube)
Membrane outlet flow restrictor to drain
(Yellow Tube)
Quick Connect Fittings & Tubing Connections
To ensure a secure seal using quick connect fittings:
Cut tubing
with the end square. An angled cut or distortion of the
tubing will not provide an efficient seal and may cause leaks.
Remove blue locking clip
from fitting before installing tubing. Push
down on the fitting collet and remove the plug. Keep the clip. The plug
may be discarded.
Push the tubing into the fitting,
to the pipe stop. The collet (gripper)
has teeth which hold the tubing firmly in position while the 'O' Ring
provides a permanent leak proof seal.
Check the Seal:
Pull on the tubing to check it is secure. It is good
practice to test the system prior to leaving site and/or before use.
Replace blue locking clip
after tubing is installed.
To Disconnect:
Ensure system is depressurized before removing
fittings. Remove the locking clip. Push in the collet against the face of
the fitting. With the collet held in this position the tube can be removed.
The fitting can then be re-used.
