FOGGING FOR INSECT CONTROL
CAUTION
Before placing any formulation in the Formulation Tank, the operator should be thoroughly
familiar with starting and stopping the pulse jet engine. If you are operating the machine for
the first time, start and stop the engine a few times. This is also a good idea for experienced
operators who may be operating a new machine or who may be reactivating an old machine
after repairs or after a period of inactivity. Refer to the appropriate sections for starting and
stopping instructions.
WARNING
READ THE SECTION ON SAFETY PRECAUTIONS BEFORE PREPARING TO DISPENSE FOG.
READ AND THOROUGHLY UNDERSTAND ALL INFORMATION, CAUTIONS AND WRNINGS
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 ACCORDING TO THE
CHEMCIAL FORMULATION WHICH IS BEING USED.
SELECTING A FORMULATION
(MODEL 2630)
OBSERVE AND FOLLOW ALL CAUTIONS AND WARNINGS LISTED ABOVE.
The 2630 is designed to dispense liquids and mixtures of a nonflammable nature. See
CAUTIONS and WARNINGS on the machine in this Manual.
When beginning to fog with the 2630, liquids or mixtures of liquid and powder are forced to
the injection point by air pressure in the Formulation Tank.
At the injection point, the liquid is sprayed at a right angle to the flow of air from the Pulse Jet
Engine. As the liquid emerges from the Spray Tube, it is sheared into droplets by the air flow.
These droplets are further reduced in size by shock waves created by explosions and the turbulent
air-flow.
Since the liquid is exposed to the heat of the engine for a very short period of time, no
significant damage is done to the powders or chemicals suspended in the liquid carrier.
It is important that wettable powder mixtures be applied as soon after mixing as practical to
avoid powders settling out of suspension and causing clogging of the formulation system. The
tendency of wettable powders to settle out may be decreased by use of an appropriate additive.
Consult your formulation distributor or the formulation label concerning the availability of additives for
the particular active ingredient in the mixture you intend to use.
It is a good idea to put only as much formulation in the tank as is necessary to do a particular
job. Thus, the Formulation Tank will be empty when the job is finished. Leaving formulation
mixtures in the tank can lead to clogging of lines and orifices.
