NOTE: When cutting the permeate tubing, you may experience some water leakage.
6. Using a length of 3/8" polyethylene tubing, connect the
icemaker/dispenser line with the free port on the compression tee.
7. The shut-off valve should be installed as close to this port of the tee
as possible. Shut-off valve should be installed in the OFF position
Consult manufacturer's guidelines before installing the shut-off valve.
8. Completely open cold water supply.
9. Open tank valve.
10. Turn off the drinking water faucet.
