3.6 Principle overview
3.7 Calibrating the hot water valves
The Mixers are supplied with water by the Dispensing
Valves DV1 and DV2.
The water valve DV4 also called the ‘dump valve’,
either doses the water or supplements the total dose in
a cup.
In the unlikely event that one of the valves needs re-
placing, it should be calibrated to one of the dispensing
speeds given in gure 5 after it has been tted.
When calibrating valves, use the special
Valve Calibra-
tion
menu by opening the
Service Menu
and going to
2.7 Hardware Test / 2.7.2 Calibrating Valves
.
The hot water dispensing valves are accessible by
dismantling the canister plateau behind the ingredients
canisters ( g. 5a).
