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. Connect the alligator clips remembering the brown or red wire is positive
and the blue or black is negative. The other end of the power loom features a plug
with keyway to ensure connection with correct polarity that connects to the pump. 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 wiring loom is installed with a 10 amp blade fuse to prevent any potential
damage to the electrical system of the vehicle.
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.
Slowly twist the tip of the nozzle from a course droplet size to a fine droplet to your preference. You can check the
spray pattern by spray pattern by spraying water on to a dry concrete floor.

Maintenance
Dispose of unused chemical and water used for rinsing in a manner that will not endanger people animals or
the environment.
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.
