BASIC CONCEPT OF THERMAL FOGGING
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 buon is pressed, the compressed air pressurizes the fuel tank, causing fuel to flow to the injector and then into the carburetor. Air/fuel mixture is then ignited by a spark plug in the carburetor. The spark is created by an ignition coil which is powered by the vehicle’s baery. The ignition coil, battery and compressor are all housed inside of the main body of the machine. Operating at its opmum 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 soluon is heated up to around 1,400º C and dispersed into millions of ny droplets (around 10-30 microns in size) creating a dense and visible smoke.

CHECKLIST BEFORE STARTING THE UNIT
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 ghtly. Note: Please make sure you only add the prescribed amount of fuel.
fill the chemical tank and connect to the thermal fogger
Pour the special fogging chemical mixture into the chemical tank. It is important not to add more chemical mixture than it’s needed. Leaving remaining chemical in the tank aer use, could affect the performance of the machine next me you use it, as deposits may solidify in the system. When you finish filling the tank, close the tank cap ghtly. 
Connect the power and remote control
Connect the 12V power lead (right) and remote control cable (le) as indicated in the picture below. Once plugged in, connect the power lead directly to the baery using the cigaree lighter plug. Red (Posive), Black (Negave). Once connected, check that the green power light on the control remote is on. Note: Please make sure solution tank switch on the remote control is turned to the “OFF” position before connecting the power
To turn on the machine
Make sure that the solution switch on the remote control is on the “OFF” position. Press the start button (one resonator at me) and keep it pressed for 5 seconds aer you hear combustion starng (sounds like a small explosion). It is necessary to keep the machine on for about 10 seconds to warm up before turning on the solution switch. TIP: If the machine fails to start , press the button “KNOCKING” so the pressure in the fuel tank can be re-established. Press the start button again and repeat the above procedure until it starts.
To start fogging
Once the machine has heated up for 10 seconds, flick the solution and switch to the ON position. When you are ready to start fogging, turn clockwise the Chemical Flow Regulator (FIG 1.12). Note: This valve also regulates the amount of flow/chemical being used, by turning it le to right.
To turn off the machine
Flick the solution switch to the OFF position and press the STOP button. Turn the Chemical Flow Regulator an-clockwise to stop the flow of chemical. Tip: Aer use, keep the machine in operaon for 5 seconds to help get rid-off any chemical mixture sll in the system.
MAINTENANCE
Cleaning the Chemical Tank and Pipes
Fill the chemical tank with 25% of clean water and turn on the unit. This will prevent corrosion and the accumulaon 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 secon with a wire brush. Make sure that there is a space of 3 to 5 mm between the electrode and the earth.
Fuel injector Maintenance
Unscrew the fuel Injector situated on the back of the machine (FIG 2.4). Clean the injector with compressed air. 
Maintaining the valve petal
Remove the top of the carburetor. Check the gasket and 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. 
TROUBLESHOOTING
If there is no ignition:
- Listen for any noises coming from the engine
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 in the carburetor). To solve this problem, first press the buon “KNOCKING” and then press the “START” button unl you hear the machine ignite. Repeat this procedure several mes if it doesn’t start the first me.
- Check the spark plug
Remove the spark plug using a spanner or spark plug remover. Hold the plug by its plastic cap and press the start buon to check if there is a spark between the electrode and the earth. Also you should hear if there buzzing sound from the ignition coil. Note: The ignition coil can be accessed through the “Rear access cover”
If there is no spark:- Clean any carbon deposits in between the electrode and the earth with a wire brush.
- Check that there is a distance of 3 to 5 mm between the electrode and the earth.
- Check that the vehicle’s battery is fully charged.
- Check that the battery and ignition coil are working. If necessary, replace the battery or coil
- Clean the contacts and check all the wires
Once these checks have been carried out, try starting the machine again.
- Check the fuel is being injected into the carbureor.
Examine the fuel hose connected to the fuel flow control valve and injector (FIG 2.2) is not blocked. If there is a lack of fuel adjust fuel supply with the fuel regulator valve. Make sure the fuel tank is full before starng the machine. Make sure the seal in the petrol caps are not damaged. Make sure the caps are firmly closed. Check the fuel injector (FIG 2.4). Clean the injector with compressed air if blocked. 
Check the Petal Valve.
Remove the spark plug cap, filter and unscrew the carbureor. 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.
- Aer 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.
Remove carbon deposits in the heat tube inside de resonator with the wire brush provided. Use and forward and backward moon.
The machine doesn’t fog or doesn’t fog enough:
- Check that the chemical regulator is opened. This is done by turning it clockwise. Make sure that the Tank Chemical Supply 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
