HOT WATER TEMPERING VALVE
Located on the cup warming tray. You can regulate the temperature of the water
coming from the hot water tap without unduly influencing the steam pressure.
Using a very fine screwdriver turn the adjustment screw to increase
/ decrease the hot water / cold water mix as per the indications on the cup tray
panel. Turning the screw clockwise increases the water temperature.
The hot water tempering requires line pressure to work properly. Therefore the
system works only when the machine is hard plumbed.
