output of the final stage and RO faucet (Point H).
You may neatly organize the tubing, but leave enough length so the filter system can be moved
freely in and out of the cabinet when replacing filters.
Step 8: Leak Stop Valve (ALS1) Installation
The Leak Stop Valve is a reusable mechanical leakage protector. It will shut down the feed water
whenever a water leakage is detected.
Step 8. a. Make sure the end of the tubing is cut square before connecting it to the fitting.
Step 8. b. Follow the water flow direction indicated on the Leak Stop Valve to connect it to the
water inlet pipeline.
Step 8. c. Tape the bottom of the Leak Stop Valve against the floor.
