TABLE OF CONTENTS

Dear Valued Customer,
Congratulations on selecting Dyna-FogRand one of the finest and compact
Ultra-Low-Volume (ULV), machines in the world. The Mini-LiteTM is the newest in
the Dyna-FogRfamily of spraying equipment, and represents the latest in portable
spray technology. The Mini-LiteTM was developed to provide a powerful yet
affordable multi-purpose machine in a portable, lightweight package.
Trials have proven the Mini-Lite™’s effectiveness. Its simple operation and portable
design, combined with the ability to produce variable flow rates make the
Mini-LiteTM the most powerful machine of its type for dispensing liquids in the 20
micron range.
Backed by our Quality, Workmanship and more than 50 years of service, we are
confident that the Mini-LiteTM will be a valuable addition to any spraying program.
Thank you for choosing Dyna-FogR.
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. The most efficient method is to break up the liquids into
aerosols and distribute these fine droplets over the target area. The small droplets
stay suspended for longer periods of time due to their size and are distributed more
evenly, remaining effective longer.
The term ULV is an abbreviation for Ultra-Low-Volume, the technology used to treat
areas with small amounts of chemical in an aerosol form. These chemicals are
usually in a more concentrated state than chemicals used in other methods of
application.
For best results, the Dyna-Fog ULV aerosol generator model 2990 should be
operated and maintained in compliance with this manual. Insecticides must be
applied in compliance with their label instructions.
WARNING
READ AND THOROUGHLY UNDERSTAND ALL INFORMATION, CAUTIONS
AND WARNINGS ON THE FORMULATION LABEL WHICH MAY AFFECT
PERSONAL SAFETY. KNOW ANY DANGERS OF THE SOLUTION USED AND
KNOW WHAT TO DO IN CASE OF AN ACCIDENT INVOLVING THE SOLUTION.
ALWAYS USE THE APPROPRIATE SAFETY EQUIPMENT AND DRESS
ACCORDINGLY TO THE CHEMICAL FORMULATION WHICH IS BEING USED.

MACHINE SPECIFICATIONS

The Mini-LiteTM is powered by a 40cc Tanaka 2-cycle gasoline engine. The
Mini-LiteTM is designed to offer a Low operational cost with a complete and compact
aerosol generator.
The engine and blower assembly are mounted on a lightweight steel tubular frame
with vibration isolators between them.
The Engine is used to belt drive a 3-stage High-Volume Blower. The engine has a
fixed but adjustable throttle control that allows to obtain the ideal working engine
operating speeds.
The blower supplies air thru a flexible hose to the boom and to the nozzle where the
air creates a “suction” on the formulation supply tube.
The suction in the formulation
supply tube causes liquid to be
drawn from the formulation tank,
thru a 3-way selector valve, onto
a metering valve, into a 2-way
solenoid valve and to the nozzle.
The nozzle has six stationary
fins that create a swirling effect
of the air mass as it leaves each
nozzle. In the center of this
swirling air mass is a liquid
supply spray tube. The spray
tube directs the formulation into
the air mass where it is sheared
into billions of tiny droplets
(10-20 micron) and propelled
thru the air to their target.
This unit is equipped with a flushing system that is controlled from the manual 3-way
valve. The flushing liquid is conveyed to the nozzle in the same manner as the
formulation.
NOTE: The system must be flushed after each use.

1) Uncrate the unit and remove all packing materials.
NOTE: It is a good idea to retain the original machine shipping carton for
storage.
2) Place the remote control unit where it will not be damaged while the machine
is being installed.
3) Remove the machine from the shipping skid by removing the screws that
retain the shipping brackets. Keep the brackets for mounting the machine to
your Golf cart, vehicle or trailer bed.
4) Activate the dry charge storage battery according to the following instructions:
CHARGING THE BATTERY
Battery: 12 V, 7.5 AH, sealed (Nonspillable) maintenance-free rechargeable battery
Caution:
Contains toxic material (lead) and corrosive fluid (acid) – Keep away from children
Flush with water at once if contaminated with electrolyte (acid)
Do not charge in gas tight container
Do not short the battery terminals
Do not incinerate
Unlawful to discard in landfill
Recycle with automotive battery scrap at an EPA or other registered facility
Automatic Sealed Lead Acid Battery Charger
This charger is designed to fully charge a battery and maintain it at the proper storage
voltage without the damaging effects caused by trickle chargers.
The length of time required to fully charge a battery is dependant on the state of
discharge. Discharging a battery deeply is not recommended, nor should they be
stored in a discharged state for very long. This results in a condition known as
“sulphation” which is effectively a permanent reduction in energy storage capacity.
CAUTION
Do not attach leads to battery in reverse polarity or short leads while charger is
plugged in.

ASSEMBLY INSTRUCTIONS

1. 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.
2. Pass the remote control unit through an open window (if any) and locate it
within reach of the person operating the machine. If permanent vehicle
installation is desired, the remote control cable can be fed through a clearance
hole in the vehicle chassis and then reconnected. When drilling clearance
holes, ensure that all sharp edges are removed and covered to prevent
premature wearing of the remote cable. When routing the cable to the vehicle
cab, do not allow the cable to be exposed to any sharp edges. Avoid sharp
bends when routing the cable. Once the cable has been routed to the cab,
reseal all drilled openings to prevent moisture and/or exhaust gases from
entering the cab.
3. Using the (2) hold-down brackets used for mounting the machine to the
shipping skid, securely mount the machine to the bed of the vehicle (see
diagram below). Depending on the type of bed surface, it may be necessary to
use additional mounting hardware to secure the machine. Dyna-Fog® offers
an ATV/Wheel mounting kit to fit a wide range of mounting surfaces.

WARNING
READ AND UNDERSTAND THESE SAFETY
PRECAUTIONS BEFORE OPERATING MACHINE
1. ENGINE AND FUEL: This machine uses gasoline mixed with 2-cycle oil 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. DO NOT attempt to put fuel in tank while the
machine is still running. Avoid smoking or open flames in area when handling
gasoline. Never run the unit indoors unless exhaust is vented to outside.
These fumes contain carbon monoxide which is colorless and odorless and
can be fatal.
CAUTION
DO NOT OPERATE ENGINE WITHOUT MUFFLER.
NOTE: The engine is equipped with a muffler that has spark arrestor
which is required in some States.
DO NOT TOUCH HOT MUFFLER, CYLINDER OR FINS WHEN HOT AS
CONTACT MAY CAUSE BURNS.
EXCEPT FOR ADJUSTMENT, DO NOT OPERATE THE ENGINE IF AIR
CLEANER OR COVER DIRECTLY OVER THE CARBURETOR AIR
INTAKE IS REMOVED.
DO NOT RUN THE UNIT IF THE BELT GUARD IS REMOVED.
2. MACHINE DAMAGE: Never operate a machine after it has been damaged. A
damaged machine can be very hazardous.
3. WIND: Spraying during windy conditions is not usually practical because the
formulation will drift out of the intended area. However, under NO
circumstances should spraying into the wind be attempted. This may cause
hazardous accumulations on the machine or carrying vehicle.
11
SAFETY PRECAUTIONS

4. 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. First Aid Kit.
c. Eye Wash Solution.
d. Safety Glasses.
e. Container of Oil Dry Compound.
f. Gloves Rated for High Temperature.
g. Respirator Adequate for Formulation being used.
5. CHILDREN: Many spraying operations are performed in residential areas,
commonly at dusk. This presents the operator with the problem of children
who are attracted to the noise and/or mist being created. Children have been
observed running into and riding bicycles through the mist. The possible
hazard lies in the toxic effect of some formulations, the severity of which
depends upon the chemical used, mist density and the length of time of direct
exposure.
IT IS THE OPERATOR'S RESPONSIBILITY TO DISCOURAGE ANYONE
FROM PLAYING IN THE MIST OR BEING NEAR THE MOVING VEHICLE.
6. FORMULATIONS: Ensure that formulations are applied only in strict
compliance with the formulation label as well as local, state and federal
regulations and that these formulations are dispersed only by trained
personnel of public health organizations, mosquito abatement districts, pest
control operators or other qualified personnel.
a. Always comply with any requirements for protective clothing, goggles,
gloves, facial masks or respirators required on the formulation label.
b. Do not exceed the dosage set forth on the registration label of the
insecticide to be used.
c. Always store formulation in its original labeled container.
7. BLOWER PRESSURE: The appropriated blower pressure is generated when
the engine is running above 8000 RPM.

PRE-SPRAY CHECK LIST

In order to achieve consistent results in generating aerosols with a Volume
Median Diameter (VMD) 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:
1. The available energy flow (air flow) through the nozzle is governed by the
blower speed. As the air mass and its velocity through the nozzle
decreases, the droplet size (VMD) will increase assuming that the liquids
viscosity and flow rate remains constant.
2. The flow rate of the liquid governed by the opening of the flow control
valve.
3. The viscosity of the liquid.
Various liquids have different viscosities. Viscosity is defined as a fluids
resistance to flow commonly measured in units of a centipoise (CP). Generally,
the thicker the liquid, the greater the viscosity and the higher the CP number.
Examples of some liquid viscosities are:
LIQUID VISCOSITY (CP)
WATER 1
DIBROM 3-4
DOW MFC 3-4
PYRETHRIN, RESMETHRIN 6-7
DURSBAN 1.5 ULV 12-14
TECHNICAL MALATHION 28
TO MEASURE THE FLOWABILITY (VISCOSITY) OF YOUR FORMULATION:
1. Place a sample of the formulation liquid
to be dispensed in the relative flowability
meter provided with the machine such that
the liquid level is above the top line.
2. Hold the meter vertical and allow the
liquid to flow through the brass orifice at the
outlet end of the meter into an appropriate
container.
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.

CURTIS DYNA-FOG Ltd.

NOTE: Periodically calibrate the flowability meter using plain water. Water
should flow through the orifice such that the time between the top line and the
bottom line is 32 + 2 seconds.
Once the flowability of the liquid has been measured, the following table can be
used as an approximate guide for setting the Metering Valve for your spray
application.
FLOW RATE TABLE
The flow rate indicated in above table is the average value of several machines
tested and 20” vertical distance between the nozzle at the boom and the liquid
level inside the tank.
The Dyna-FogRNozzle will produce 90% of the droplets below 20 microns (ULV)
when used at the recommended flow rates. This meets the requirements of all
current chemical labels for controlling flying insects.
When the high flow rate is discharged through a single nozzle the Mini-LiteTM will
produce larger droplets suitable for applying a residual deposit to vegetation and
any other surface.
Note: Always handle and dispose of all chemicals in accordance with the
manufacturers instructions and the material safety data sheet for the chemical
being used.
