3-WAY VALVE: The manual 3-Way brass valve is used as a selector to route either formulation or flushing solution from their respective tanks to the nozzle. The in line formulation filter with stainless steel filtering element mesh # 80 is attached to the 3- Way valve.
FOREWORD The application of insecticides is the predominant method by which man attempts to control the size of insect populations. Due to environmental and economical reasons, it is desirable to treat a given area with the least amount of insecticide that can be made to be effective.
WORKING PRINCIPLES An 8 Horsepower, four-cycle gasoline engine with a flexible coupling on its output shaft is used to drive a positive displacement rotary-blower. The air entering the blower is first filtered through a large stainless steel filtering element. The blower supplies air pressure to the nozzle.
ASSEMBLY INSTRUCTIONS Uncrate the unit and remove all packing materials. NOTE: It is a good idea to retain the original machine shipping carton for storage. Place the remote control unit where it will not be damaged while the machine is being installed. Remove the machine from the shipping skid by removing the three lag screws that retain the shipping brackets.

CAUTION NEVER FILL BATTERY IN MACHINE, AS SPILLS WILL DAMAGE FINISH AND CAUSE PREMATURE CORROSION AND / OR DAMAGE TO COMPONENTS. Charge 12 volt battery at 3 - 4 amps until the acid temperature is above 80 C), and the hydrometer reading is 1.250 or higher. Acid temperature must never exceed 125 F while charging.
MACHINE INSTALLATION Remove the machine from the skid and lift the machine onto the vehicle with the discharge end of the machine toward the rear of the vehicle. Pass the remote control unit through an open window (if any) and locate it within reach of the person operating the machine.
SAFETY PRECAUTIONS WARNING READ AND UNDERSTAND THESE SAFETY PRECAUTIONS BEFORE OPERATING MACHINE ENGINE AND FUEL: This machine uses gasoline as the fuel for the internal combustion engine and all precautions commonly applying to this volatile fuel should be observed. Exercise extreme caution to avoid spilling of gasoline. If spillage occurs, wipe it off and allow evaporation time before starting the engine.

SAFETY EQUIPMENT: In addition to any safety equipment that may be required by the type of formulation which is being used, the following items should be mandatory for each vehicle which carries this machine during fogging operations. a. Fire Extinguisher, chemical-type rated for fuel fires. b.
MACHINE OPERATION CAUTION READ THIS COMPLETE OPERATION SECTION AND THE SECTION ON SAFETY PRECAUTIONS BEFORE STARTING THE MACHINE FOR THE FIRST TIME. For first time operation, the sections on MACHINE INSTALLATION and MACHNE OPERATION must be performed before proceeding with this section. When operating this machine for the first time, move to an uncongested and well- vented work area away from flammable materials.
PRE-SPRAY CHECK LIST Verify that the remote control box is within easy reach of the operator. Verify that the boom is in the correct position as required for the spraying operation to be accomplished, and that the ring clamp which allows this positioning is tight.
ENGINE PREPARATION Oil Recommendations Change and add oil according to chart below. Do not overfill. Use high quality detergent oil API classified “For service SC, SD, SE, SF, SG”. If oil remains in the engine, oil viscosity must be suitable for the lowest temperature at which the engine will be operated in service.
STARTING THE ENGINE CHOKE ENGINE: Move engine choke control to position lever in "choke" position (pulling the control rod). NOTE: This should fully close choke on carburetor. NOTE: The manual choke is provided for cold starting of the engine. Once the engine has been allowed to warm-up, choking the engine should not be needed for restarting.
BLOWER LUBRICATION – MINI-PRO A simple but very effective lubrication system is employed on UNIVERSAL RAI blowers. At the drive shaft end the bearings are grease lubricated using hydraulic pressure relief fittings. These relief fittings vent any excess grease, preventing pressure build-up on the seals. A restriction plug and metering orifice prevent loss of lubricant from initial surges in lubricant pressure but permit venting excess lubricant under steadily rising pressures.
MEASURING LIQUID FLOWABILITY (VISCOSITY) In order to achieve consistent results in generating aerosols with a mass median diameter (MMD) in the sub 20-micron range, several variables must be kept under control at the same time. The ability of an aerosol generator to consistently break up a liquid into appropriate sized droplets depends on (3) key elements: The available energy flow (air flow) through the nozzle is governed by the blower speed.
Page 20
3. Using a stopwatch or a watch with a sweep second hand, determine the flowability time in seconds that it takes for the liquid level to fall from the top line to the bottom line. Once the flowability of the liquid has been measured, tables on next page can be used as an approximate guide for setting the pump flow rate and nozzle boom pressure for your spray application, taking into account the expected Droplet size.
REMOTE CONTROL BOX FUNCTIONS MACHINE SWITCH OFF: Removes +12 V DC system power and grounds gasoline engine ignition to kill the engine. MACHINE SWITCH ON: Applies +12 V DC system power and removes ground from gasoline engine ignition. This position also applies power to Machine L.E.D.
FILTER - SILENCER (Rotary Blower) A) General: The air blower filter - silencer is mounted on the air blower. Dirt and other foreign particles are filtered from the incoming air by means of the reusable stainless element. The design is such that it partially silences the air also. NOTE: Do not run the machine without this filter silencer assembly;...
FORMULATION FILTER The system is equipped with an in line low profile filter located at the formulation tank standpipe. This filter is to prevent any foreign matter from entering the Pump, solenoid valve and the nozzle system. Located inside the filter housing is a fine mesh stainless steel screen and an Aflas gasket seal.
HI-FLEX COUPLING INSTALLATION INSTRUCTIONS FLANGE AND BUSHING INSTALLATION Make sure the bore and tapered cone surface of the bushing and flanges are free of all foreign substances such as paint or dirt. 1 Place *QD bushing on the shaft over the key with flange end first. The end of the bushing should be located according to the distance indicated in the Engine and/or Blower part list.
Page 26
3 The second *QD bushing is placed on the other shaft as described in step 1 and the second flange assembly is slipped over the bushing and assembled to the distance of 7/8" (as indicated in below/left drawing) apart following the instructions in step 2.

FLEXIBLE Make sure the beads of the ELEMENT element are fully worked down upon the seats of covers as ELEMENT’S BEAD shown in the detail on the right drawing. insure proper seating, rap on the tire O.D. with a small mallet until the split is closed.
3-WAY VALVE The corrosion resistant 3-Way manual valve is attached with a metal bracket to the center post of the machine, and is used as a selector to route either formulation or flushing solution from their respective tanks to the nozzle. This is done by placing the valve lever into either the “FORMULATION”...

After each application of formulation the system must be flushed to protect the equipment from the corrosive material in the formulation. To Flush System: · With the engine and blower operating, place the lever of the 3-Way valve into the “FLUSH” position ·...
DIAPHRAGM PUMPING SYSTEM The Dyna-Fog’s Diaphragm pumping system was designed to accurately pump various types of liquid formulations at Ultra-Low-Volume. Bigger droplet size can also be obtained with higher flow rate and/or lower boom pressure. HYDRAULIC SCHEMATIC With the diaphragm pumping system, the flow rate of the liquid is controlled by a needle valve as a bypass regulator between the suction (“IN”) line and pressure (“OUT”) line of the pump.
Diaphragm Pump Calibration Instructions (By-Pass Loop System) Refer to the flow tables provided with your machine to determine the proper orifice fitting and valve setting to produce your desired flow rate. When you receive your machine (or if the tank is ever completely emptied) carry out steps 1-7.

BYPASSING THE AIR PRESSURE SWITCH The air pressure switch is part of the logic of the circuit, allowing the operation of the formulation pump only if the air boom pressure is present. With this feature the machine is not able to pump (spill) the formulation with the engine/blower “OFF” (stopped).
DIAPHRAGM PUMP The diaphragm pump included with your machine is the latest from the pump manufacturer. IMPORTANT: Spare parts order for your Diaphragm Pump. When placing a spare parts order, please inform us that your machine is including the new version of the diaphragm pump, which includes integrated bypass in the upper housing, and the...
