Checking and adjusting the water inlet pressure
  1. Check the water inlet pressure at the pressure reducer of the building’s drinking water installation.
    Under no circumstances may it exceed the maximum value specified in the Chapter Technical data.
    We recommend setting the water inlet pressure to 0.4 MPa (4 bar).
    If there is no pressure reducer in the drinking water installation of the building, a separate pressure reducer must be connected upstream of the device.
    If the value of the water inlet pressure cannot be determined in the drinking water installation of the building, a separate pressure reducer must be connected upstream of the device.
Installing the tap
  • Select the installation position so that the tap is accessible for installation from below and the opening of the outlet is above the sink.
    Allow sufficient space for connecting the 1/4″ line.

  • The material thickness A of the sink / worktop must not exceed 24 mm. If the material thickness is higher, the worktop can be provided with a corresponding countersink from below. If in doubt, have the device installed by a person with professional knowledge.

  • The upper and lower support surfaces must be flat and parallel, with a diameter B of at least 50 mm.

Installation diagram Illustration D
  1. Drill a hole with a diameter C of 12 mm for the installation of the tap. Use suitable drills or tools for the material of the sink / worktop. Pre-drill if necessary.
  2. Remove the protective film from the anchor plate.
  3. Fit the anchor plate and the sealing washer on the tap.
  4. Insert the tap into the hole from above and align it.
