Note : There will be occasions when the hose retaining ring will not provide a suitable
solution for Fluid Category 3 installations. In these instances an outlet double
checkvalve must be fitted, this will increase the required supply pressure typically
by 10 kPa (0.1 bar). Double checkvalves fitted in the inlet supply to the appliance
cause a pressure build up, which affects the maximum static inlet pressure for the
appliance and must not be fitted. For Fluid Category 5, double checkvalves are
not suitable.
