Preparing to Install the SW200XL Water Conditioner Ultra

If you have any doubts about your DIY skills, please be sure to have your SW200XL Water Conditioner Ultra installed by a licensed professional plumber. For a detailed installation guide see the SW200XL Water Conditioner Installation Instructions

What comes in the box?

  • The SW200XL housing unit
  • A black/orange drain valve used to flush or rinse out the unit (at least once a month for best performance).
  • (Optional) Two 1″x3/4″ adaptors will also be included if you have requested them
  • Mounting bracket and seal for hanging the unit

Installation Tips

  • Remember, you are treating and filtering the entire incoming water supply for the whole house
  • Choose an easily accessible frost-free location near the main water supply for your home
  • You want to ensure that it’s easy to drain and clean the Conditioner once a month.
  • A hose can be attached to black/orange drain valve to make draining and rinsing easier
  • Verify the size of the water piping thread on which the filter will be installed.
  • The SW200XL unit comes with 1″ inlet/outlet as standard.
  • If your pipes are not the size of the filter thread you will need to use adapters.
  • The threads needs to be covered by a thread sealant for use with drinking water before making the connection.
  • We have found it best to use both Teflon tape and liquid Teflon.
  • On the top of the filter unit, you will see two small arrows to show the direction of the flow of water.
  • Before first use, flush the unit by opening the valve for 60 seconds (use a bucket underneath to catch the water)

Tools or Optional Supplies Required

You’ll need the following tools if you choose to make this a DIY project.

  • A drill and assorted drill bits
  • 2 adjustable wrenches, different sizes
  • A tubing cutter
  • Bucket to catch any water remaining in main supply pipe after shut off
  • Adapters may be required on each side of the Conditioner to attach your pipe size.
  • Optional – Shut-off valves

Installing the SW200XL Water Conditioner

  • Turn off the main water supply and drain the system.
  • Choose the new location for the conditioner unit and mark it. If located outside the house, choose a location that is safe from frost and extreme weather. Keep in mind you’ll have to drain and service the conditioner once a month so choose a location you can reach comfortably.
  • Cut the pipe using a pipe cutter.
  • Optional but recommended – install a shutoff valve for water entering the filter and one for water leaving the filter
  • Install the compression nut and plastic or brass fittings according to the manufacturer’s instructions. It’s recommended to use pipe thread tape on the fittings for better sealing.
  • Install the conditioner with the “in” and “out” ports facing the right directions.
  • Turn on the main water supply and check for leaks.
  • The installation is complete. Every time you need to drain and clean the conditioner, turn the valve on the bottom of the filter unit.
