Operating the liquid system
MANIFOLD SYSTEM
The “Manifold System” is located at the left side of the
sprayer, permitting operation of most of the (fitted)
accessories from one position. The modular design of
the Manifold system allows the easy addition of many
accessories to the plumbing system of the sprayer. The
system can be expanded to a maximum of 4 valves on
the pressure side. The suction side can be expanded to
a maximum of 2 valves. The system is also fitted with
an agitation valve, enabling the tank agitation to be
turned on or off. It also features a self-cleaning filter
return hose on/off valve, which allows the return to be
turned on or off.
Use of MANIFOLD valve system
The Manifold valve faces are colored discs for easy
identification:
Green disc = Pressure valve
Black disc = Suction valve
Yellow disc = Self-cleaning filter
A function is activated/opened
by turning the handle
towards the desired
function
Symbols (shown below) are fitted to the faces of the 3-
way valves indicating the direction of flow of the liquid.
*Agitation
Normally, Agitation should be on, but please refer to
the following rules of thumb:
1. Choose “Without Agitation” if a high level of
foaming occurs, in order to reduce the
amount of foam.
2. Choose “Agitation” when using powder
chemicals in order to avoid sedimentation.
3. Close the agitation valve if spraying with
a high volume and it is impossible to
achieve sufficient operating pressure.
