Range of under counter units providing (near) instant boiling and chilled water (Quadra/Sahara /Eco models) or chilled and ambient water (Alpine 125 model) through the XL, XT or XR taps. Where products are supplied with the XL, XT, XR taps the flow is controlled via a solenoid valve incorporating a plastic strainer which is activated by a lever (XL tap), touch method (XT tap) or a remote control (XR tap). The under counter units incorporate a combined pressure limiting valve (set at 5.0 Bar) and a double check valve assembly (suitable for backflow protection against Fluid Category 3) on the inlet and are supplied with a loose stainless steel braided PEX lined flexible hose assembly incorporating a ½” captive nut end connection for installation on the inlet. The under counter units also incorporate a water filter on the cold supply after the solenoid valve. The filter head inlet incorporates an approved single check valve cartridge (however, the complete product has not been fully tested to demonstrate it provides adequate backflow protection - but is incorporated after the double check valve assembly). (The filter is installed downstream of the combined pressure limiting valve and a double check valve assembly). The Quadra and Sahara plus models incorporate a venturi block assembly fed [cold water] from and then [hot water from hot tank] back to a mixer tap (not supplied). The venturi block assembly incorporates an approved check valve cartridge (however, the complete product has not been fully tested to demonstrate it provides adequate backflow protection). Under counter unit supplying XL, XT, XR taps: Maximum inlet pressure 10.0 bar. Cold supply only. Maximum working temperature of the instantaneous heater (where incorporated - model dependent) 98.5°C. Quadra and Sahara plus models mixer tap (not supplied) cold supply and hot water circuit: Maximum working pressure 10.0 bar. Maximum operating temperature 60°C.
