  • Page 18 The installation should be equipped with a pressure reduction if the main water supply pressure is higher than 5 bar (0.5MPa). The pressure reducing device has to be installed at the beginning of the distribution network (before the safety valve). We recommend a supply pressure of 3 - 4 bar (0.3 to 0.4MPa). It is recommended to use a permanently fixed pipe for the connection between the machine and the tap water, and not allow to use a hose-set for the connection.
