      Installation requirements: With the exception of model 62915-500107 , these taps have a
      type AUK3 air gap and are therefore suitable for backflow protection up to fluid
      category 5, when installed correctly. Model 62915-500107  has a waterfall type spout and
      therefore a compliant double check valve or some other no less effective device
      providing backflow prevention protection to at least fluid category three shall be
      fitted at the point of connection(s) between the water supplies and the fitting or
      appliance. For all models, inlet supply hoses need to be installed where light is
      excluded
