The Dramm Autofog applys chemicals under the
low-volume (LV) principle. This means that the same
amount of active chemical is applied to a given area,
but the chemical is diluted into reduced amounts of
water. Because LV application is very efficient, many
users have found that lower volumes of chemical can
be used with the same results.
The Mini Autofog MLVH-10A will require a
minimum of 2 liters of water and the chemical to treat
5,000 square feet. If less than 5,000 square feet is
treated, a minimum of 2 liters of water is still used.
The specially designed solution tank and agitator
prevents concentrated chemicals from precipitating.
According to conventional high-volume (HV) spraying
methods, approximately 20 gallons of water (diluent)
plus the chemical is needed to treat 5,000 square feet.
LV application is only possible when extremely fine
particles are produced. The patented nozzle design of
the Mini Autofog MLVH-10A produces particles which
will range in size from .5 to 10 microns in diameter. Air
enters the nozzle from the oil-less compressor and
then exits the nozzle at super sonic speeds. This
movement of air creates a venturi that draws solution
from the chemical tank. As the solution exits the
nozzle it is micronized into billions of tiny particles.
The micronized chemical particles stay suspended for
up to 6 hours and are distributed by horizontal airflow
fans (HAF) and natural air currents.
The Mini Autofog MLVH-10A features manual
starting and a timer for automatic shut-down. Other
features include a safety valve on the compressor to
release any abnormal pressure build-up. The motor
which drives the compressor is supplied with a
grounded electrical cord set and is protected from
overheating with a thermal fuse that disconnects
power to the entire sprayer. The Mini Autofog MLVH-
10A now has a redesigned frame and handle to ease in
its transportation in small greenhouses and storage
facilities.

Precautions / Pre-Operation Checklist
D. Cold weather operation: When the temperature falls
below 32°F run the compressor in a warm environment
before placing the MLVH-10A assembly in the area to
be treated. The bearing grease may harden in very cold
temperatures causing the compressor to not preform
properly. Unless absolutely necessary, do not operate
the MLVH-10A in sub 25°F weather.
E. You will get an accurate output volume if
the nozzle cap is closed completely and
then returned to match the red check
marks. See diagram below.
NOTE:
Output volume will vary 2.5 - 3.0 cc/min. for each
notch in the nozzle cap.
•Clockwise: Output INCREASES
•Counterclockwise: Output DECREASES
NOTE:
Check the O-ring located inside the nozzle cap for wear
or damage. Replace if necessary
Dramm Autofog MLVH-10A Manual 8
A. For the most effective performance, the treatment area
must be air tight. Take time to repair any broken glass,
torn poly and gaps or openings in vents and door
frames.
B. The entire treatment area should be vacant. No
humans or pets should be present.
C. It is recommended that the application process take
place at the end of the day. Secure the treatment area
and post hazard signs before spraying.
D. Avoid spraying when the temperature is over 85°F in
the treatment area or when relative humidity exceeds
85%.
E. When utilizing horizontal airflow fans (HAF), run them
for 1/2 hour longer than actual spraying time.
F. Follow all EPA Guidelines regarding the application of
chemicals.
A. Test run the MLVH-10A with clear water for 1-2
minutes. Observe the spray quality.
B. The discharge volume rate of clean water is
approximately 45 cc / minute. When testing the
unit, pull the suction hose out of the solution tank
and place it in a graduated cylinder (fill it with 90
cc of clean water). The cylinder should be empty
after a 2 minute test run. Be sure to check the
discharge volume rate regularly to assure best
results.
C. Observe the operating pressure. The gauge will
read 14-23 PSI.
NOTE
: Check for leaks in the
piping when the pressure is too low. Eliminate
clogs if the pressure is too high. Pressure readings
may vary from location to location. Small
differences are inconsequential.
Compressor/Sprayer
Treatment Area
WARNING: The standard model Autofog uses a
nozzle that is manufactured with brass components.
The use of oxidizers will damage this nozzle
within several applications.
If you plan to use oxidizers in your Autofog,
CONTACT DRAMM BEFORE THE FIRST USE OF YOUR
MACHINE to purchase a stainless steel nozzle at a
reduced cost. After your machine has been used,
Dramm cannot accept the original nozzle
back for credit.

1. Determine the treatment area size in square feet.
NOTE:
A minimum of 2 liters of water should be added to the
active chemical when treating less than 5,000 square
feet. More water should be added to dilute larger
volumes of chemical (to a 15 to 1 ratio).
2. Calculate the chemical amount.
Example: Labeled chemical rate per 100 gallons is 16
ounces. We will first calculate a rate for 10,000 square
feet.
Low Rate: 16oz. X 0.20 = 3.2oz.
(for 10,000 square feet)
High Rate: 16oz. X 0.35 = 5.6oz.
(for 10,000 square feet)
NOTE:
Divide the rate per 10,000 square feet by
2 for the rate per 5,000 square feet. If you are treating
areas less than 5,000 square feet, make the rate
calculation for 5,000 square feet and reduce that
amount proportionately. Contact the Dramm Service
Department at 800-258-0848 or 920-684-0227 if you
have any questions.
3. Calculate the water volume for at least a 15 to 1 ratio
for wettable powder and flowable formulations. Mix
water with chemical in the mixing pitcher. Pour the
mixture into the solution tank through the strainer.
Eliminate dirt and globs of chemical that may clog the
nozzle. When using wettable powders, make a lump-
free slurry of the powder to wet it completely and then
add the remaining portion of water. For ECs use a 10:1
dilution ratio.
4. Position the MLVH-10A for spraying.
5. Install the solution tank on the sprayer and insert the
nozzle suction tube. Make sure the suction tube
reaches the bottom of the tank. When a full chemical
tank is loaded onto the MLVH-10A, do not move the
machine to avoid spilling the chemical solution.
6. Connect the MLVH-10A to a 120V 60HZ power source
and set the timer by rotating past and then returned to
the desired spraying time. The spraying process
begins immediately – vacate the
treatment area.
NOTE:
Always wear protective clothing, gas mask, hood, gloves
and boots when mixing chemicals and using the MLVH-
10A.
1. WARNING: All EPA Guidelines on the handling,
application and re-entry periods for chemicals must be
adhered to. Only crops which are listed on the
chemical label should be treated.
2. Labeled chemical rates are stated in amounts of
chemical to be diluted into 100 gallons of water. Most
chemical labels do not advise how much of the spray
concentrate should be applied to a given area.
3. Greenhouse growers apply from 25 to 300 gallons of
spray concentrate per 10,000 square feet, the average
high volume application is 40 - 50 gallons per 10,000
square feet.
4. The MLVH-10A is a low-volume applicator. Low
volume means application of chemical in a very
concentrated solution. The same amount of chemical
is applied to a given area as conventional spraying, but
in greatly reduced quantities of water. This is possible
since low volume equipment produces very small
particle sizes (0.5 to 10.0 microns) versus conventional
spray particles of 100 to 400 microns.
5. If you would normally spray 25 gallons of solution into
10,000 square feet of area you are applying 25% of the
chemical mixed in 100 gallons of water. (Per labeled
rate per 100 gallons).
6. The charts starting on the following page will help you
calculate the proper chemical amounts and water
volumes.

The MLVH-10A should be allowed to run for a half
hour after all chemical has been expelled into the
air. See the chart below for approximate amount
of time it takes to expel chemicals. These times
were compiled with clear water - the expulsion
time time may exceed these guidelines when
mixed with chemicals.
Times may vary due to the consistency of solution
being sprayed. Thicker solutions
may take longer to discharge.
1. Plug the AutoFog into the appropriate power
source.
2. Set the clock to the correct time. The timer is a 24
hour timer for accuracy between day and night.
3. Determine the spray starting time and stopping
time.
4. Flip ALL of the pins between the starting and
stopping time to the OUTSIDE. (see photo below)
5. The AutoFog will run only during the time that the
pins are flipped to the outside of the clock. DO
NOT FLIP THE START TIME AND STOP TIME
ONLY. Each pin represents 15 minutes of time.
6. The AutoFog is now ready and will begin fogging at
the appropriate time. Make sure the treatment
area is secure and will be empty of all personnel at
that time.
NOTE:
Remember to add a half hour to the spraying time
when setting the timer.
1. Vacate the treatment area, secure all entry ways
and post hazard signs.
2. Prepare the chemical solution. See page 10 for
dilution rate details. Be sure that the solution is
free of clumps of chemical that may clog the
nozzle. Use a whisk or blender to make a smooth
paste of wettable powder solutions. Check that
the suction tube screen is in place in the tank.
Pour the solution through the large solution
strainer/ funnel assembly to eliminate any unmixed
chemical or debris.
3. Plug in the main power cord. Notice the power
lamp illuminated on the control panel.
4. Set the timer. Turn the dial past, then return to
the desired operation time. The MLVH-10A will
begin to spray, vacate the treatment area
immediately.
5. If horizontal airflow fans are used, allow them to
run a half hour longer than the predetermined
spray time.
6. In order to allow all of the spray particles to settle,
do not re-enter the treatment area for a minimum
of 6 hours after the MLVH-10A has completed its
operation. Keep the structure airtight. However, if
it is necessary to enter the treatment area during
application, only do so in a full spray suit, boots,
gloves, hood and respirator.
7. After spraying, ventilate the treatment area with
fresh air and clean the MLVH-10A thoroughly.
Follow all EPA Guidelines for re-entry.
