The ASV-14QW automatic shut-off valve can be installed on any standard reverse osmosis (RO) system used in the home to optimize performance. This valve automatically shuts off production when the tank pressure reaches approximately 65% of the incoming line pressure when the storage tank is full. Using an automatic shut-off valve with your RO system can save you from up to 15,000 gallons per year of unnecessary water use.

Instructions

  1. The 'in & out' markings are on the top of the valve. The top side of the valve is the high pressure side and the bottom (screws visible) side is the low pressure side
  2. Insert the tube feeding the membrane inlet into the ASOV IN/OUT fittings: Insert the tube from the PREFILTER Outlet into the IN fitting
  3. Insert the opposite tube end that feeds the Membrane INLET into the OUT fitting. NOTE: The IN & OUT markings are the top of the valve - THIS IS THE HIGH PRESSURE FEED SIDE
  4. Insert the tube feeding the tank from the Product Water port of the membrane housing: Locate the Product Water outlet from the membrane housing (on the end w/ 2 ports: center is Product water, side port is Rinse/Drain)
  5. Insert the Product water tube from the membrane housing into either 'Tank' fitting of the valve (ie Low Pressure side). Insert the opposite tube end that feeds the Tank into the other 'Tank' fitting of the valve
  6. The valve automatically shuts off production when the tank pressure reaches approximately 65% of the incoming line pressure to indicate the tank is full
  7. The ASO valve saves thousands of gallons of water. Reverse Osmosis Systems without an Automatic Shut-Off valve continually send rinse water to the drain even when the tank is full
  8. Feed water goes through a set of three prefilters (Sediment, Carbon, Carbon), passes through the ASOV, and then goes to the RO membrane to produce RO water. The RO water passes through the system to be stored in the water tank
  9. When the tank fills with RO water and the tank pressure reaches 40 psi, the back pressure will reverse the ASOV diaphragm and will shut off due to the pressure differential
  10. When the RO water end pressure is greater than the Feed water pressure, it causes the piston to move downward and shut off the in and out channel. When the ASOV In and Out channel shuts off, the system will not produce any RO water
