Designing
A System
There are many ways, tips and techniques to install an Automist
automatic insect control system. Nozzles are commonly placed in
areas that offer the highest rate of insect control effectiveness.
In residential settings a variety of methods can be used to achieve
lower mosquito populations. Attaching spray nozzles to fence lines,
deck railings, in hedges, trees or on retaining walls can accomplish
the goal of perimeter control. Some yards do not lend themselves to
these applications. For yards that have limited landscaping or
attaching structures, underground risers are a good option.
Indoor insect control for livestock facilities can be
accomplished with a simple formula, one spray nozzles for every 1000
cubic feet. A 10' x 10' horse stall with a 10' ceiling is a good
example for the area one nozzle can cover. Although this example is
ideal, one nozzle can cover a 12' x 12' stall just fine and ceiling
height can be as high as 14 feet.
Suggestions & Hints
1. When figuring a system
for a barn or building, first determine the square footage of the areas to
be sprayed.
2. Figure one nozzle line
for each 12 feet of barn width.
3. Figure an elbow nozzle
assembly for each end of each nozzle line, with tee nozzle assemblies in
between.
4. When over 2 nozzle
lines are used, extra tubing tees, fittings and tubing will be required to
connect the lines to the feed line.
5. If other areas, such
as additions or other rooms are to be sprayed, you will have to add nozzles,
tubing and fittings. If a total of 50 nozzles or more are required, figure
3/8 inch tubing for all feed lines.
6. If the facility is
over 120 feet long, the feed line should be 3/8 inch tubing.
7. If the facility is
over 150 feet long, the feed line should be 3/8 inch and you should figure 1
cross feed line for each 75 feet of barn length... EXAMPLE, if the facility
is 160 feet long there should be a cross feed line 40 feet from each end of
the facility, providing equal feed for equal distances for each line.
8. If more than one
facility is to be figured, place the basic unit (pumping unit) in the larger
barn with the basic unit on the side closest to the 2nd facility.
9. For multiple barns,
feed each barn from the basic unit by figuring a tee fitting at the pump
outlet. Use 3/8 feed lines in all multiple barn applications.

Example
A 36' X 90' facility
with a nozzle mounting height of 9 feet. Square footage of the barn is
3,240 square feet. The sizing chart shows 133 square feet for a 9 foot ceiling.
Take the 3,240 square feet and divided by 133 square feet per nozzle = 24
nozzles required for the facility. Horse stables use one nozzle assembly for
every 10'X 10' or 12' X 12' stall. For best results, nozzles should also be ran
down the alley, one nozzle assembly every 12 feet.
