Checking and setting the water inlet pressure
- Check the water inlet pressure at the pressure reducer of the building’s drinking water installation. It must never exceed the maximum value specified in Technical data. We recommend setting the water inlet pressure to 0.4 MPa (4 bar). If there is no pressure reducer in the building’s drinking water installation, a separate pressure reducer must be connected upstream of the device. If the inlet pressure value cannot be determined in the building’s drinking water installation, 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.
