BASIC CONCEPT OF THERMAL FOGGING

3
PRINCIPLES OF OPERATION
VectorFog™ Thermal Foggers are powered using the pulse jet principle. Pulse jet engines don’t have any moving
parts; instead they have a funnel shaped combustion chamber similar to a rocket engine which opens into a long
resonator or exhaust pipe. VectorFog thermal foggers have an auto start and operate through compressed air via a
compressor. When the auto start button is pressed, the compressed air pressurizes the fuel tank, causing fuel to flow
to the injector and then into the carburettor. Air/fuel mixture is then ignited by a spark plug in the carburettor. The
spark is created by an ignition coil which is powered by a rechargeable battery. The ignition coil, battery and
compressor are all housed inside of the main body of the machine. Operating at its optimum performance,
combustion and injection is repeated with a frequency of around 200-250 cycles per second. Once the machine
starts, the chemical tank also becomes pressurized by means of a non-return valve. A close valve and supply valve
are then opened to allow the flow of the chemical/oil solution in to the resonator. At this stage the solution is
heated up to around 1,400º C and dispersed into millions of tiny droplets (around 10-30 microns in size) creating a
dense and visible smoke.

CHECKLIST BEFORE STARTING THE UNIT
Unpacking the unit
When unpacking the unit, please make sure that that the machine is not damaged and that all the accessories
mentioned in this manual are not missing.
Charge the battery
Make sure the right power supply is being used (110/220 volts). Connect the charger to the unit and then connect to
the mains. When first purchased, the machine requires around 8 to 10 hours to fully charge.
Fill the fuel tank
Fill the tank with undiluted petrol using a funnel. Fill the tank to a third of its capacity. When you finish filling the
tank, close the tank cap tightly. Note: Please make sure you only add the prescribed amount of fuel.

Fill the chemical tank
Pour the special fogging chemical mixture into the chemical tank. It is important not to add more chemical than it’s
needed. Once you have used the machine, please make sure there is no chemical left in the tank. Chemicals can
solidify and could block the system next time round. When you finish filling the tank, close the tank cap tightly.

To turn on the machine
Press the power button “START” and keep it pressed for 8 to 10 seconds once you hear combustion starting (sounds
like small explosions). After the engine starts, leave the machine to warm up for around 10 to 20 seconds before
opening the chemical valves.
TIP: If the machine fails to start, press the STOP button (air release) so pressure can be re-established. Press and hold
the start button again for 10 seconds until it starts. If it fails to start, repeat the procedure.

To start fogging
Once the machine has heated up for 10 seconds, first turn the “Close Valve” and then the chemical supply valve
slowly counter clockwise. On SF models you will need to switch the directional valve situated on top of the resonator
to fog oil based chemicals, by turning it clockwise.

To turn off the machine
Turn the “Chemical Supply Valve”clockwise to stop the supply of chemical to the resonator. Before turning the
“Close Valve”off, keep it running for 5-10 seconds to get rid-off any chemical mixture still in the system. Once you
are sure that all the Chemical has been burned off. Turn the Close Valve and press the STOP button located on top of
the fuel tank to stop the machine. Important: Never switch off the machine without closing the chemical valves in
the order shown below. Failure to do this could cause the system to back-fire.

MAINTENANCE
Cleaning the Chemical Tank and Pipes
Fill the chemical tank with 25% of clean water and turn on the unit. Then open the chemical supply and close valves
to flush it through. This will prevent corrosion and the accumulation of chemical deposits in the tank and pipes.
Spark Plug Maintenance
Remove the spark plug using a spanner or spark plug remover. Remove any carbon deposits between the electrode
and the earth section with a wire brush. Make sure that there is a space of 3.5 mm between the electrode and the
earth.
Fuel injector Maintenance
Unscrew the fuel injector situated on the side of the carburettor. Clean the injector with compressed air to remove
any blockages. Important: Never use a metallic punch to clean the injector. The injecting hole is calibrated for
optimum performance

Maintaining the valve petal
Unscrew the fuel filter and regulator (if applicable) before unscrewing the top of the carburettor. Check the valve for
any distortions or cracks. If it’s damaged, you will need to replace this part. TIP: It’s important to assemble the parts
of the carburettor in the order there where disassembled. The distance between the petal valve and the valve plate o
should be approximately 1 mm.
COMMON TROUBLESHOOTING
If there is no ignition:
If there is noise coming from the engine but there is no ignition, this could be because the engine has flooded (an
over-supply of fuel and air in the carburettor). To fix this, press the STOP button (air release) so pressure can be re-
established. Then press and hold the “Start”button again for 10 seconds until it starts. If it fails to start, repeat the
procedure.

Check there is a spark coming from the spark plug:
Clean any carbon deposits in between the electrode and earth with a wire brush.
Check that there is a distance of 3.5 mm between the electrode and earth.
Check that the battery is fully charged.
Check that the battery and ignition coil are working. If necessary, replace the battery or coil
Clean the contacts and wires inside the battery case
Once these checks have been carried out, try starting the machine again. If the machine doesn’t start, replace plug.
• Check the fuel injector is not blocked.
Examine the fuel hose located on the side of the fuel tank to make sure it’s not blocked. Make sure the fuel tank is
full before starting the machine. Make sure the seal in the petrol cap is not damaged. Make sure the cap is firmly
closed to prevent leakage. Unscrew the fuel injector and examine that the injector hole is not blocked. If blocked,
clean with compressed air.
• Check the Petal Valve.
Remove the spark plug cap, filter and unscrew the carburettor. Examine the petal valve to see if it’s damaged. If it’s
damaged, replace petal valve. TIP: It’s important to assemble the parts of the carburettor in the order there where
disassembled. The distance between the petal valve and the valve plate o should be approximately 1 mm.

The machine is turned on, but the engine works intermittently or stops:
• Examine the fuel tank assembly to check for any leakages.
After pressing the start button, cover the tank and connections with soap to check for leaks. If bubbles are observed,
the gasket needs replacing on the fuel tank cap or the tank itself.
• Clean the resonator.

10
Remove carbon deposits in the resonator with the wire brush provided. Use and forward and backward motion.
The machine doesn’t fog or doesn’t fog enough:
• Check that the chemical supply valve is opened. This is done by turning it anticlockwise. Make sure that the close
valve is set to the open position.
• Unscrew the main chemical inlet nozzle from the resonator and clean it using compressed air to remove any
blockages.
• Check there is no leaks in the chemical tank. Blow compressed air backwards though the chemical tube from the
inlet nozzle to see if any bubbles appear. Replace leaking parts if necessary.
