Valves and symbols (optional)
The valves of the valve system are distinguished by coloured
identification on the function labels. Symbols corresponding to every
possible function of use are located on the discs for easy identification
and operation. A function is activated by turning the handle towards the
desired function.
Correct valve positions are:
(A) Pressure valve
This valve selects to direct pressurized liquid to spraying or tank rinsing.
The active function is indicated by the indicator pointing at the label of
the required function.
(B) Agitation valve
With this valve you select whether return liquid should be directed back
to the pump or is used for agitation in the tank.
If the valve is kept closed the liquid will be directed back to the main tank. When the tank is nearly empty, the handle is
turned to pump so that the liquid is directed to the suction side of the pump in order to fully empty the tank prior to
cleaning.
(C) Suction valve
This valve selects suction from main tank for spraying or rinsing tank for cleaning purpose.
Turn the handle up or down to vertical position so the indicator points towards the label of the required function.
μ
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.
