Agitation Valve (Green symbol)
With the adjustable agitation valve it is possible to combine spraying
with a high volume rate at high pressure with agitation at the same time.
This is controlled continuously by the valve:
The valve is marked with an arrow on the disc which indicates the
amount of liquid that passes through the valve.
Choose your own valve setting, depending on the tank contents:
• The handle is turned to a position near the tip of the arrow: Only a small amount of liquid is allowed to pass the valve
resulting in a lesser extent of agitation.This is recommended when using chemicals with a low density to prevent
foaming in the tank.
• The handle is turned to a position in the wide end of the arrow: A large amount of liquid will pass the valve resulting
in a large extent of agitation. This is recommended when using chemicals with a high density, which will tend to settle
at the bottom of the tank.
External Cleaning Valve (Green symbols)
This valve directs the fluid to the two spray guns used for cleaning.
• Turn the handle to the left to use the spray gun for cleaning the
EasyClean filter and CycloneFilter nearby.
• Turn the handle to the right to use the spray gun connected to the
hose reel for cleaning the sprayer outside.
