Curtis Dyna-Fog BLACKHAWK 2620, Instruction Manual

Page: 17 / 55

DO NOT FOG INTO THE WIND.
DO NOT LEAVE THE FOG CONTINUOUSLY DIRECTED AT THE SAME AREA OR OBJECT.
THIS MAY CAUSE A BUILD-UP OF A FLAMMABLE SUBSTANCE OR LEAVE UNDESIRABLE
DEPOSITS ON WALLS, FURNITURE, ETC.
The formulation output of your machine is controlled by the injection orifice you choose to install at
the injection point of the engine tube. The model 2620 Blackhawk is shipped with 4 different orifices
and the model 2630 Mister III is shipped with five. The “orifice number” is stamped on the side of
each orifice body and the approximate flow rates for each orifice size are shown in the table below:
TABLE 3
NOTE
The above flow rates are considered an average and may vary depending on: the viscosity of the
formulation to be fogged, the formulation tank pressure, and the operating characteristics of the
engine. These flow rates are based on a formulation having the same viscosity as ordinary tap
water. (1 centipoise)
CAUTION
When it is intended to fog in a closed area, the operator should first test the fog to verify that
it is dry, before entering the closed area. To test the fog quality, pass a dark piece of paper
or a shiny object through the fog at a distance of approximately 24 inches (61 CM) from the
discharge (exhaust) end of the machine. If there is any visual accumulation on the paper or
object, the fog must be considered wet and the formulation metering orifice changed to a
smaller size. Give yourself a margin of safety in selecting the formulation output orifice for a
dry setting.
