Thermo-Gen® Operational Instructions

DESCRIPTION

The Thermo-Gen machine utilizes a reaction engine operating on the pulse-jet principle.

METHOD OF OPERATION

When starting, a controlled mixture of fuel and air is combined, forced into the combustion chamber, and is

ignited by the spark plug. After starting and warming (5-15 seconds) the unit continues running automatically

on auto-ignition without utilizing additional spark or electricity from the batteries. When the fog tap is opened,

air pressure is directed through a pressurizing valve into the formulation tank. Air pressure transfers the

formulation by hose through the fog tap and into the pulsating stream of hot engine exhaust gases. The kinetic

and thermal energy of the engine gasses vaporize the injected fog solution into micro-size droplets. At the end

of the fog pipe micro-fine aerosols are ejected and condense as a visible fog. The Thermo-Gen is a thermal

fogger, a fogger which uses heat to produce fog droplets.

WARNING - READ AND UNDERSTAND INSTRUCTIONS BEFORE STARTING OR OPERATING THIS MACHINE

When you receive the Thermo-Gen unit, your first impulse will be to start the unit immediately. Before

starting the unit, please carefully read the operating instructions completely to

avoid potential problems.

PREPARATION AND FILLING OF THE FUEL TANK

Fill the fuel tank with clean, fresh gasoline. Leaded, unleaded,

or premium gasoline may be utilized. The fuel tank holds 2.3

liters (approximately 2-1/2 quarts). The Thermo-Gen will oper-

ate for approximately 1-1/2 hours on a full tank or fuel. Normal

fogging applications can be performed with 1 liter (34 ounces)

or fuel or less. Always utilize the graduated fuel pitcher with

strainer when filling the solution tank. The Thermo-Gen unit al-

ways starts and runs better on a fresh tank of gasoline.

PREPARATION AND FILLING OF THE FORMULATION TANK

- Test start unit prior to filling formulation tank -

1. Remove tank lid by unscrewing tank cap counterclockwise, pull

out solution intake hose and filter and hang on holder.

2. Loosen the rubber tank fastener by tugging it downward. Remove

the formulation tank in upright position.

3. The formulation tank has a maximum capacity of 9 liters (306

ounces). After filling the formulation tank use the lid attached to the

tank to seal the formulation tank.

4. Re-attach the formulation tank to the unit, unscrew the tank lid,

and insert the formulation hose and filter into the formulation tank

and seal the formulation tank with the attached lid.

PREPARATION FOR STARTING

Press down on the primer [Part #210], you should be able to hear the buzzing sound of the electronic ignition

system. If no sound is audible conduct systems check on starting system.

Systems Check Instructions:

Remove the spark plug cap [Part #209 A] from the sparkplug [Part #180], lift spark plug cap 2 mm (1.8”)

above spark plug and press primer. Jumping spark

in spark plug cap makes a crackling sound, con-

firming that the entire system is operational. Re-

attach sparkplug cap to sparkplug.

STARTING THE UNIT

1. Be sure that the fog tap [Part #120] is in the verti-

cal/OFF position.

2. Turn the adjustable fuel needle valve [Part #103z]

a half turn (counter clockwise) (See Figure 4). This

starting point may vary considerably between ma-

chines and geographic location due to differences in

atmospheric pressure and whether or not the ma-

chine is still warm from a recent start. When starting

a cold machine open the fuel needle valve [Part

#103z] slightly more, when starting a warm machine,

slightly less.

A. Push the orange primer ball [Part #210] down and

hold it down for 1-2 seconds. Simultaneously have

fingers ready on the fuel needle valve [Part #103] so

that you can immediately open the fuel needle valve

farther for full power (See Figure 5).

B. The machine will start with a roar. Slightly open the fuel needle valve [Part #103] to keep the machine running.

(If the machine stalls repeat step 2A).

C. Open the fuel needle valve [Part #103] slightly farther. Notice that the machine sounds differently at various

levels of adjustment.

D. The fuel needle valve [Part #103] is adjusted to

fill operating power when the unit makes the harsh-

est sound.

3. Occasionally the machine may accumulate air

bubbles in the fuel line just below the carburetor. Air

bubbles can occur during refueling and are caused

by a lack of gas in the fuel line at the time of refuel-

ing. These air bubbles may cause the machine to

run erratically. Remedial action for erratic operation

caused by air bubbles is to while the unit is running

lift the machine 2” off of the ground and gently tap

the bottom of rear of the machine on the ground forc-

ing air bubbles out of the fuel line. It may be neces-

sary to re-adjust the fuel needle valve [Part #103z] to

full power.

4. During the starting procedure it is possible to acci-

dently flood the engine. (See instructions for clearing

a flooded engine).

Figure 5

Figure 4



5

INSTRUCTIONS FOR CLEARING A FLOODED ENGINE

1. Remove cap from fuel tank.

2. Turn fuel needle valve [Part #103] to the off position and depress the primer ball [Part #210] down 4 or 5 times.

With each push of the primer ball the machine will roar or rumble until it is no longer flooded. Once the roaring

has stopped the carburetor Part #63 is free of excess fuel.

3. Repeat the starting procedure being careful not to open the fuel needle [Part #103z] quite as far. Adjust the

fuel needle valve Part #103 so machine operates with harshest sound.

FOGGING

Open fog tap by pushing forward to a horizontal position. When

sufficient air pressure builds up in formulation tank until the

machine will begin fogging.

PROPER SHUTDOWN PROCEDURE

1. Close the fog tap [Part #120] (See Figure 6)

2. Always open formulation tank lid [Part #113] before turning

fuel needle valve Part [#103z] to the off position. (See Fig-

ures 11 & 12)

3. Close fuel needle valve [Part #103z]. Do Not Overtighten.

(See Figure 4)

POTENTIAL FOR CORROSION: If proper shutdown proce-

dure is not followed water based fogging formulations may

corrode the entire fuel system resulting in eventual mechani-

cal failure.

POTENTIAL FOR CORROSION CONTINUED

After fogging water based formulation, flushing the system is

recommended. To flush the system remove the formulation

tank [Part #114], clean and rinse the formulation tank [Part

#114]. Fill formulation tank [Part #114] with 2 liters (68 ounces)

of clean water. Start unit. Raise rear of unit approximately

5mm/2 inches. Open fog tap and flush system by fogging

water for 2 minutes. Shut down unit following correct shut-

down procedure. Remove formulation tank [Part #114], drain

tank, add several ounces of isopropyl alcohol (rubbing alco-

hol) to tank, sloshing alcohol in tank will capture the remain-

ing droplets of water, drain alcohol from formulation tank [Part

#114], and reinstall formulation tank [Part #114].

PERIODIC FLUSHING IS RECOMMENDED

1. Drain the formulation tank.

2. Properly store leftover fogging solution.

3. Pour 1 liter/1 quart of kerosene, No. #2 fuel oil or diesel

fuel into the formulation tank and slosh it around thoroughly

inside the tank.

4. Take the machine outdoors and fog out excess flushing

solution for several minutes. Then drain remaining flush-

ing solution.

5. Clean fuel filter intake [Part #139z] as needed.

STANDARD GENERAL OPERATING PROCEDURES

1. Always operate your machine at the harshest sound level.

2. Always release the pressure on the formulation tank by loosening the tank lid.

3. Clean machine after each use.

4. Flush machine after each use.

Your Thermo-Gen has only three requirements to function:

IGNITION SPARK - FUEL - AIR

Your Thermo-Gen unit has neither pistons, rings, nor valves to wear out as does an ordinary internal combus-

tion engine, the Thermo-Gen must be cleaned and maintained in order to operate properly.

REQUIREMENT (1) IGNITION SPARK

A strong, hot spark is a requirement for proper starting. Occasionally the electrode on the spark plug may

become heavily soiled. Or it may be damaged by rough handling. Annually clean or replace the spark plug as

required. The proper gap is the thickness of a 10¢ US coin. Electricity is provided by four (4) “D” sized batteries.

Replace the batteries annually or as required.

The electrical system of the Thermo-Gen unit is very similar to that of a standard flashlight. Eventually, the

tension spring inside the grey battery housing tube will relax and not make proper contact. As with a flashlight

simply disassemble, unscrew the sheet metal screw, and pull out the tension spring to improve contact.

Note: To check spark, remove the spark plug from the resonator, reinstall the spark plug cap onto the plug and

touch the electrode of the spark plug into the stain-

less steel cooling jacket. Depress the orange primer

ball. A blue spark between the electrode of the spark

plug and the spark plug tip should be visible.

REQUIREMENT (2) FUEL

Premium, regular or unleaded gasoline may be used.

Fill the unit with fresh gasoline before each use. The

unit always starts and performs best on a full, fresh

tank of gasoline. Prolonged storage of gasoline in

the unit’s fuel tank can result in condensation which

can adversely affect the machine’s starting and over-

all performance. Use of a fuel conditioner helps pre-

serve gasoline between uses and helps improve win-

ter starting. Two ounces of fuel conditioner is suffi-

cient for a tankful. Store gasoline in plastic fuel stor-

age cans between uses to prevent rust particles from

clogging fuel needle valve [Part #103].

TEST FOR PROPER OPERATION OF FUEL SYSTEM

A. Remove fuel needle valve [Part #103] from the carburetor [Part #63].

B. Remove the spark plug, push down on the orange primer ball. A mist of gasoline should be visible spraying up

from the needle valve hole in the carburetor body. If no fuel is visible check the fuel line for leaks.

ADDITIONAL MAINTENANCE TIPS AND REQUIREMENTS

A1. DO NOT substitute round fuel hose for the oval fuel hose [Part #96] below the red fuel valve [Part #7980].

The oval fuel hose [Part #96] acts as a fuel pump and is essential for proper operation.

A2. Occasionally the red fuel valve [Part #7980] may be damaged, replace as required.

REQUIREMENT (3) AIR

Proper combustion requires the proper amount of air, at the proper place, and at the right time. Maintenance on

the AIR SYSTEM is performed every 25 hours of operation by simply replacing the diaphragm [Part #72]. (Your

machine is equipped with a spare diaphragm. The diaphragm is cupped slightly to the outside refer to repair

diagram for proper diaphragm installation technique).

Warning: Read, understand and respect these safety precautions before operating

machine. Failure may lead to a fire hazard. Operator must view the instructional video

and/or be trained by Unsmoke Systems authorized personnel.

- Check the functional safety of the machine each time before using it. For sta-

tionary operation, ensure machine is properly supported.

- Never refuel machine when the machine is hot!

- Be careful not to place fuel into the solution tank!

- When filling one of the tanks or when inspecting the carburettor, smoking is

prohibited in the immediate environment.

- Never let the machine run without supervision. Operator shall close the fogging

tap immediately after sudden stop of engine.

- Do not fog in rooms where there is a danger of dust explosion. (e.g. grain mills)

- Do not fog directly into a pipe with a similar diameter as the fogging pipe of the

unit (cooling effect of the unit is interrupted and a combustible concentration of

aerosols may occur).

- Do not fog with combustible liquids into pipes or tunnels without ventilation be-

cause of fire and explosion hazard.

- Do not fog any liquids with a flash point of less than 167ºF.

- When fogging combustible liquids use only machines equipped with an auto-

matic cut off device for the fogging liquid.

- Never exceed quantity specified on formulation label instructions when fogging

within enclosed spaces.

- If a combustible atmosphere is established a source of ignition may cause

fire (e.g. electric sparks). Therefore such sources have to be eliminated or

turned off.

- When fogging any liquids a fire extinguisher shall be kept near the unit.

- Do not transport hot machines in enclosed vehicles. Never ship the machine

with fuel or agent in the tank. If there is still fuel in the tank during transportation,

the machine must be upright and secured against tilting.

- Do not touch the fogging pipe while the engine is running and up to 30 minutes

after run. Do not touch the protection jacket (cooling jacket) for 30 minutes after

stopping the engine (danger of injury due to radiated heat)!

- Immediately eliminate and clean up machine-related leakage or spillage.

- Have the machine periodically serviced by a qualified technician or return to

Unsmoke Systems for service and repair.

- Observe the instructions for use supplied by the pesticide manufacturer.

- When fogging, use protective equipment such as protective clothing, proper

respiratory protection, protective gloves, and ear protectors as applicable. The

type and quality of the protective equipment to be used depends on each

country’s safety and legal requirements. In Europe the filter cartridge for the

gas mask (full-face mask) must meet the protection category A2 B2-P3 as a

minimum requirement.

Brief Operating Instructions:

Start Fogging:

1. Wait until the machine is cool before filling the fuel tank. (minimum 1/2 full)

with normal or unleaded gasoline. Gas should have room temperature (mini-

mum 10°C - 40°F).

2. Open adjustable screw on carburetor a max. 1/2 turn, if unit is warm, 1/3 turn.

3. Slowly press primer down several times until unit rumbles and starts. Adjust to

a rough harsh around (this allows the machine to achieve the most efficient out-

put and optimal cooling effect).

ATTENTION! Unit should never run with a high pitched

sound (high frequency) because this leads to a loss of power

and overheating.

a) If the unit does not start after pumping approx. 5 times and no rumbling or

roaring can be heard the carburetor probably is flooded. In this case open lid

of fuel tank and pump several times until unit runs. Replace lid immediately.

4. As soon as machine is running with a powerful harsh sound open fog tap. If

necessary adjust again motor sound.

Stop fogging:

1. Loosen lid of chemical tank while motor is running (pressure escapes allowing

chemical pipes to be sucked out). Point the end of the fogging pipe (exhaust

pipe) downwards until no more fog is produced.

2. Close fog tap.

3. Stop engine by gently closing the adjustable screw.

Attention (After fogging materials other than UNSMOKE THERMO-55):

1. After fogging detach and rinse out chemical tank. Refill with a small amount of

water or cleaning solution to fog away left over residues.

2. Observe detailed operating instruction and safety regulations.

ADDITIONAL MAINTENANCE

FUEL NEEDLE VALVE MAINTENANCE

Periodically lubricate the "O" ring on the fuel needle valve Part #103.

Lubricate both the "O" ring and the threads. The proper lubricant is

silicone grease which is available at most automotive parts stores.

FUEL HOSES AND VALVES

Insure that fuel hoses and valves are properly aligned.

TESTING FUEL VALVE

To test red fuel valve part #7980 simply attach a rubber hose to the end of

the valve and blow. If air escapes or if it does not open and close smoothly

with each breath of air, it is defective and requires replacement.

FUEL FILTER/INTAKE

Periodically clean fuel intake filter by spraying with aerosol

carburetor cleaner.

CONTAMINATION IN FUEL FORMULATION TANK

Drain fuel formulation tank. Clean interior of tank by spraying with aerosol

carburetor cleaner.

NOZZLE MAINTENANCE

A. SOLUTION INJECTOR NOZZLES

Periodically remove residue build-up on solution injector nozzles part #151

by running a long 5/32" drill bit in and out of the injector nozzles (hold drill bit

with vise grips.)

B. DOSING NOZZLES

Your Thermo Gen unit is equipped with 3 interchangeable fog nozzles. Most

applications can be made with the size 10 nozzle. Discretion is advised prior

to using larger nozzles.
