Doulton Ultracarb Twin Undersink Water Filter Installation

WARNING: This unit must be installed on the COLD water line.

      1. Find a convenient location beneath the benchtop.
      2. Using the self-tapping screws provided, attach the filter to the cupboard wall (allowing approx 50mm height for servicing). The system may otherwise stand freely on the cupboard floor.
      3. Shut Off the Water Supply
      4. Locate the water mini stop valve (see Diagram 3) for the cold water feed line. (To identify the hot and cold water pipes, turn on the hot water at the faucet. After the water is warm to the touch, feel the pipes under the sink).
      5. Close the cold water mini stop valve.
      6. Turn on the cold water at the faucet to ensure that the line is completely shut off and drained. (If there is no cold water mini stop valve located under the sink, it is necessary to turn off the main water supply at the entry to the house).
      7. Attach Swivel Compression Tee (see Diagram 2) - Unscrew the braided hose from the mini stop valve.
      8. Screw-in the swivel compression tee. Reattach braided hose.
      9. Connect the System - To make a connection, the hose is simply pushed in by hand. Please refer to Diagram 3. Where possible, leave hoses long, do not cut to an exact length.
      10. Ensure cut is straight and square with a clean surface.

Faucet Installation

      1. The pure water faucet may be installed on any flat surface over 50mm (2”) in diameter. (Remember: check the underside of the location for interference).
      2. Make a small indent using a centre punch to mark the desired drilling location.
      3. Drill a pilot hole with a metal drill.
      4. Enlarge the hole using a ½” metal drill bit.
      5. Once the hole has been drilled, install the faucet as per Diagram
      6. Be sure the faucet body, chrome plate, and the black rubber washer are placed above the sink.
      7. Install the black locating washer, the lock washer and the nut underneath, then tighten firmly while aligning the faucet in the desired direction.
      8. Install female Quick Fit Connector to the end of the faucet (see Diagram 4)

Activating the System for the First Time

Once all tubing has been connected, place the pure water faucet in the on position, then slowly open the mini stop valve. This will allow any trapped air to escape.

Check plumbing assembly and the undersink system are secure and free from leakage. If there are no detected leaks, leave the pure water running for 5 minutes to flush the new filter cartridges. Water may be slightly discoloured and have some aeration; this is normal and will clear shortly.

Allow the system to stand for 2 to 3 hours and then flush again for several minutes. Your system is now operational.
