7. Machines are designed for continuous use over an 8-hour day, but to protect components, it
is wise to turn off the machine when it is not in use. In permanent installations, it is advisable
to equip the circuit with a night cut-off device.
8. During the warm-up phase and during operations, people should not stand within one meter
of the front of the machine. Flammable material like paper, fabric, etc., should never be
placed directly on or around this equipment, or any other electrical device with a heating
element.
9. The smoke should be blown into an open space and should not be directed at people or
objects. Never blow smoke on hot surfaces, into glowing heating elements or into open
flames. The normally non-flammable and non-toxic smoke could react on very hot surfaces
and be burnt or decomposed.
10. Unauthorized repair or alteration of any safety devices can lead to improper operation and
accidents. Repairs should be performed only by an authorized Service Center.
WARNING: USE OF ANY FLUID OTHER THAN ROSCO FOG FLUIDS OR
MODIFICATION OR ATTEMPTED UNAUTHORIZED REPAIR OF THE ROSCO
MODEL 1700 WILL IMMEDIATELY INVALIDATE THE WARRANTY.
HOW THE MACHINE WORKS
When the heat exchanger has reached proper operating temperature, the operator switches
power to the siphoning pump, which draws the fluid from an external reservoir into the heat
exchanger. The fluid is rapidly heated and vaporized. The vaporized fluid is then discharged
through the nozzle into the atmosphere where, upon mixing with the cooler air, it turns into an
aerosol consisting of millions of fine particles.
NOTE: The terms “fog” and “smoke” are used interchangeable. However the ROSCO
MODEL 1700 does not produce smoke, but a mist or aerosol.
