The agitator valve can be partially opened, if desired,
to keep the chemical in suspension. Opening the valve
completely, though, will prevent spraying at maximum
pressure.
Operating Other Pump Styles
Other pump styles are available for the Wylie Power Spray
-
ers such as roller and centrifugal pumps. The controls for
the roller pump will be similar to the diaphragm pump, i.e.
an adjusting valve varies pressure and provides bypass.
The centrifugal pump has an agitator valve. The primary
point to remember is that the main tank valve must be open
to feed fluid to the pump and any air leak on the suction
side of the pump will prevent the pump from achieving
operating pressure.
Operating The Trigger Gun
The Hypro Long-Throw trigger gun sprays in a range from
a powerful straight stream to a wide angle mist. The rear
trigger handle turns the spray on or off. The front handle
adjusts the angle of the spray by rotating the handle forward
or backward. Pulling the handle back creates a straight
stream. Push the handle forward for a wide angle spray.
Special Operating Instructions For Twin Tank
Power Sprayers
If agitation is used, it is imperative that the suction
and agitator valves be open for the same tank.
Failure to do so could mix the chemicals and
overflow the agitated tank.
The Twin Tank Power Sprayers are equipped with separate
agitator systems for each tank. Open the suction ball valve
for the desired tank. To prevent contamination between the
tanks, make sure that only one suction valve is opened at
a time. Opening both valves, especially when the pump is
turned off, will allow fluid to flow between the tanks until
the volume is equalized.
When the pump is operating and agitation is desired,
make sure that the agitator valve and suction valve for the
same tank are open. Opening the wrong agitator valve will
contaminate the tank being agitated and could overflow
that tank.
