Filling chemicals by VACnMIXs Chem Probe
÷
NOTE! Before adding any chemicals, fill hopper with water to
test functions see “Filling the VACnMIX with water” on
page 60.
1.
Connect Chem Probe camlock to Ball Valve on VACnMIX, OR
Connect suction hose to the camlock fittings on the ball valve
of the hopper and the Drum coupling.
2.
With lid of VACnMIX closed, turn the Vacuum and Transfer Valve
to FILL position
3.
The vacuum is controlled by the ball valve and vent. In the
CLOSED (A) position,the ball valve is open to the suction line,
and liquid chemical will be drawn from the drum into the
hopper.
4.
To stop the flow of liquid chemical from the drum, move the ball
valve to OPEN (B) position - this allows air from the atmosphere
to be introduced to the hopper through the vent, and closes off
the suction line.
5.
To transfer measured volume of chemical mixture to the sprayer
tank, turn the Vacuum and Transfer valve to EMPTY.
6.
Flush Hopper and Sight Tube between different chemicals.
μ
ATTENTION! The hopper rinsing devices use spray liquid for
rinsing the hopper. The VACnMIX must always be
cleaned/decontaminated together with the rest of the sprayer
with fresh water when the spray job is complete.
