When installing the filter for the first time, please follow the instructions below:

  1. Turn off the incoming water supply.
  2. Locate a convenient location or section of tubing where you can install the filter.
  3. Cut the tubing using a tube cutter. Please ensure that the edges of the tube are cut clean and free of sharp burrs. DO NOT cut the tubing at an angle as it may cause the unit to leak during use.
    NOTE: There is a directional flow arrow on the filter. The incoming water should be routed to the inlet and the filtered water should be coming from the outlet or arrow head end of the flow arrow.
  4. Insert supply tubing into the end of the filter. Insert firmly until the tubing bottoms out.
  5. Turn on the water supply. Flush filter for 5 minutes or until the water runs clear.
  6. Turn off water supply.
  7. Repeat Step 5 for the outlet side of the filter. Make sure to install the tubing firmly until it is flush with the filter.
  8. Turn on the water supply and inspect the filter for leaks..
