CONNECTING TO 12 VOLT DC SUPPLY:
The Sprayer requires a 12 volt DC power source. A three metre loom is provided with the sprayer
to allow the sprayer to be connected to the 12 volt DC source available. The brown wire is positive
and the blue is negative. If you extend the wire use wire of the same gauge or larger.
An on/off switch is fitted to the sprayer to allow the sprayer to be switched off from the 12 volt DC
source to prevent accidental drain of power. The switch also allows the pump to be shut down when
the tank is empty preventing overheating and damage to the pump.
The sprayer loom includes a 10-amp fuse to prevent any potential damage to the electrical system
of the vehicle. Consult your vehicle instruction manual for correct electrical connection.
SETUP AND TESTING:
It is always recommended that you first test all spray equipment thoroughly with clean water. Silvan
Spotpaks are supplied with a blue adjustable nozzle containing a large orifice, which when twisting
the tip can allow for a greater flow of liquid. It is recommended that adjustable nozzle is used first
and can be changed later if you require.
1.
Be sure to wear safety equipment as recommended by the chemical manufacturer before adding
chemical to the sprayer
2.
Check the suction line foot filter is clean and undamaged (see Maintenance section).
3.
Fill the tank with clean water.
4.
With the 12-volt supply connected and the 6-meter spray hose and spray lance connected. Fit
the blue adjustable nozzle or any large orifice nozzle you may wish to use.
5.
Check all pipes, hoses, hose clamps and connections for leaks or damage.
6.
Switch the pump ON.
7.
Depress the spray lance trigger. The pump is self-priming and will start spraying within 30
seconds.
8.
Check the hose connections for leaks, if any are found stop the pump and rectify the problem
before continuing.
9.
By twisting the tip of the nozzle to the coarsest droplet size, the restriction to flow is minimized
and pump pulsation will not occur.
10.
Slowly twist the tip of the nozzle from a course droplet size to a fine droplet to your preference.
If the pump begins to pulsate/cycle you may require a different nozzle that is rated to allow for
higher flow rates at your selected droplet size.
11.
Once the nozzle is set and the pump operates free of pulsation/cycling, the spot sprayer is ready
to be utilized for spot spraying of chemical.
•
After spraying rinse out the spray lines and tank with clean water
•
The foot filter should be checked and cleaned if necessary, each time the tank is filled. To check
the filter hook it out with a bent piece of wire. Appropriate protective equipment including gloves
should be used whenever maintenance is carried out.
•
If heavy frosts are experienced, run the pump to make sure pump and spray lines are dry. This will
prevent water freezing in the pump or spray lines and damaging sprayer.
Installation (cont.)
Maintenance
Dispose of unused chemical and water used for rinsing in a manner that will
not endanger people animals or the environment.
