The Classic Nordic Square single tap is designed to be installed with a COMBI tank, with the option to add a CUBE tank for filtered chilled and filtered sparkling water in addition to 108°C filtered boiling water. Tap holes of 32 mm for the boiling-water tap and 35 mm for a mixer tap are required, with a maximum worktop thickness of 50. A mounting bracket is available as an optional accessory.

The COMBI tank includes thermostatic temperature regulation, a maximum temperature/pressure relief valve set at 8 bar, and a HiTAC® High Temperature Activated Carbon water filter. Warm water temperature settings range from 40–60°C, with specified volumes at 40°C and 60°C. The system is designed to operate within mains pressure between 200 kPa (2 bar) and 400 kPa (4 bar).

When combined with the CUBE tank, the installation can deliver filtered chilled water at 2,4 litres/min and filtered sparkling water at 2 litres/min. The CUBE tank has defined electrical and dimensional requirements, as well as specified minimum and maximum water and CO&sub2 pressures, and uses an HF + AC water filter. The system is compatible with S C A L E C O N T R O L R in setups that include filtered chilled, filtered sparkling and 108°C filtered boiling-water or mixer taps, as indicated.
