3M HiFlow NEP-Head System Installation instructions

  1. Identify the Cold Water braided line under your sink.
  2. Turn off the water supply by the service tap under the sink, or at the water supply meter.
  3. After turning off the water supply, release any water pressure by turning on the water cold tap.
  4. Undo the cold water brained line at wall tap or wall fitting. Note: As a general rule, fittings with coned or flat rubber washers do not require thread tape.
  5. Fit the 3M Multi-function pressure limiting valve to the other outlet of the isolation tap. The
    valve has two ¼” outlet ports, select the outlet port that best suits cupboard space and fit the
    ¼” x ½” brass nipple and use the black poly blanking plug to seal off the unused port. Use a
    small amount of the white thread tape on the fittings if they are not already taped.
  6. Note: Fittings in this kit may already be thread-taped ready for installation and use.
    Check the flow direction on the top of the system head.
    With the filter fitted to the head, check the height inside the cupboard – position system up off
    the cupboard floor [or shelf] a minimum of 50mm – this will allow sufficient space to replace
    filter cartridges.
  7. Connect a braided line from the outlet side of the Multi-function pressure limiting valve to the
    inlet side of the filter head – take care not to over-tighten sealing nuts
  8. Two different length braided lines are supplied and either may be used as the inlet or outlet
    line, whichever best suits your system positioning – take care not to kink nor over-bend nor
    stress the braided lines.
  9. Fit the other braided line to the outlet side of filter head.
  10. With the ½” x ½” Chrome Joining Nipple, join this line to the existing braided line leading from
    your kitchen cold water tap – existing braided line should be replaced if any kinks or corrosion
    is evident.
  11. Remove the filter and screw the system bracket to the cupboard. The system can be mounted
    on an angle if height is a problem. Refit the filter cartridge.
  12. Open the cold water tap on the sink and leave on to allow air to escape while flushing. Check all connections.
  13. Turn the water supply on slowly and flush the new filter for a couple of litres.
  14. Turn off the sink filter tap and check for leaks. Recheck all connections after a few hours for any leaks. As these filters are so fine you may have some air bubbles in the water for a few days, this
    will go away.

The 3M NEP-Head in your new system can take a range of 3M filters. You can change the
type of replacement filter cartridge to suit specific applications if required in the future.
