INTRODUCTION

This manual offers a detailed explanation of the operation of the ROSCO MODEL 1750 fog
machine. To assure efficient and safe operation, please take a few minutes to read this
material.

The ROSCO MODEL 1750 fog machine is a thermal aerosol generator designed for variable
fog output. It is part of a system, the other basic component being the full line of Rosco fog
fluids, and they should always be used together. These unique fluid formulations are safe
when used according to instructions. They are water-based and contain no petroleum
distillates. The operating temperature, pump pressure, and output nozzle orifice of the
machine have beeen specifically set to maximize aerosolization of the Rosco fluids. When
used properly, the system should operate for many years.

IMPORTANT SAFEGUARDS

READ AND UNDERSTAND THESE SAFETY PRECAUTIONS BEFORE OPERATING
THE MACHINE. FAILURE TO PROPERLY FOLLOW THESE PRECAUTIONS MAY
LEAD TO A FIRE, EXPLOSION, OR ELECTRICAL SHOCK.

FOG FLUID HEALTH CAUTION: VAPOR FROM THIS FLUID, LIKE ANY OTHER
COMMON MATERIAL IN A VAPORIZED STATE, MAY BE IRRITATING TO OR
CAUSE ALLERGIC SYMPTOMS IN SOME PERSONS WITH ALLERGENIC
SENSITIVITY. DO NOT EXPOSE AT CLOSE RANGE TO KNOWN ASTHMATICS.

1. This machine uses electrical power at common commercially available voltages. When
directly contacted, such voltages are hazardous to human life. All precautions commonly
applicable to the use of electric power generally are applicable to the use of this machine.
This machine is designed to operate from three-wire power systems where one of the wires is
a safety ground. DO NOT disconnect the safety ground or use extension cords or "cheater"
plugs to connect this machine to a two-wire system. Operation without a safety ground may
result in a hazardous electrical shock.

2. Check the current and voltage rating of your machine. Extension cords must be properly
sized and rated for voltage, current and length. Check your local electrical code for the correct
gauge extension cord. If an extension cord shows signs of wear or gets warm to the touch,
discontinue its use and obtain a cord with a higher current rating. Improper extension cords
are not only hazardous, but may result in poor machine performance due to excessive voltage
drop.

3. Never use any machine that shows signs of improper use. Even slight damage may be an
indication of a major problem. If the machine looks questionable, use it only under strict
observation. If the machine shows any unusual behavior, disconnect machine immediately
from power and send machine to a Service Center for repair.

4. Do not operate the machine in a tightly confined space where the ambient temperature
might exceed 135° F (57° C). A continuous flow of air is required to maintain temperature
within the machine housing. Sensitive electronic components deteriorate rapidly under high
heat conditions. Operation of the machine in an enclosure of less than ten cubic feet (one
cubic meter) is dangerous, and automatically voids the warranty.

Enclosing any heating device so it is invisible to the operator creates a potential fire
hazard, no matter what the ambient temperature of the enclosure. To do so with any
high-amperage device is to assume substantial risk. Rosco strongly recommends against
it.

5. In any facility, the fog concentration should be controlled. The fog should never mask
emergency exits, safety signs, staircases or other safety constructions.

6. After long use, or if the machine is not properly set, some liquid droplets or wet area may
appear in front of the machine’s outlet. This liquid should be wiped up to prevent a condition
where someone might slip and fall.

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 fog should be blown into an open space and should not be directed at people or
objects. Never blow fog on hot surfaces, into glowing heating elements or into open flames.
The normally non-flammable and non-toxic fog 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 1750 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 1750 does not produce smoke, but a mist or aerosol.
