General info - valve system
All functions of the spray circuits are operated via the centrally situated valve system with color coded pictorial symbols for

Valves and symbols
The valves at the valve system are distinguished by colored identification discs on the function labels. Symbols
corresponding to every possible function of use are lo
cated on the discs for easy identification and operation. A function is
activated by turning the handle towards the desired function.
ATTENTION! If a valve is too tight to operate - or to loose (= liquid leakage) - the valve needs to be serviced. Please see
the section ‘Maintenance’ for further information.
Suction valve = Blue symbols
This valve is to select suction from main tank or from the flush tank. The
handle is turned so the label for required function is directed to the
