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.

OPERATING INSTRUCTIONS
1. POWER HOOK-UP
Plug one end of the power cord into the dedicated socket located on the rear of the machine
and the other end into a socket rated at the proper voltage and amperage. The machine
requires a dedicated power circuit.
2. REMOTE CONTROL
If it is not already plugged in, plug the remote control into the socket in the cavity on the back
of the machine. Push the button marked POWER. This will turn on the machine and the unit
will start to heat up. The red HEATING LED on the remote control should light up indicating
that the machine is heating.
3. WARM UP
Let the machine warm up for about eight minutes until the green READY LED on the remote
turns on. The machine is now ready to use as long as the green LED remains on and the fluid
reservoir contains fluid.
4. FLUID DELIVERY
Place either the 2.5-liter or the 4-liter size bottles of any Rosco fluid in the cavity located at
the rear of the machine. Place the end of the tube coming out of the top of the machine into
the bottle. A cap is provided that fits on the bottle.
NOTE: The machine only works with uncontaminated Rosco fog fluids. Other
manufacturers’ fluids may cause spitting and serious clogging problems and could result in
the production of an unhealthful aerosol. The use of other fluids voids the warranty of the
Rosco Model 1750 Fog Machine.
5. PRODUCING FOG
To produce fog, push the FOG button located on the remote control. Push the switch again to
stop producing fog. The volume of the fog can be varied by turning the knob marked FOG
LEVEL. Note: At higher outputs the machine will give a large burst and then ramp back the
volume. This is to allow the machine to run continuously and is normal.
CAUTION: If the fluid bottle is empty, DO NOT run the pump. Running the machine
without fog fluid can seriously damage the pump.
6. TIMERS
The Rosco Model 1750 Remote Control is equipped with timers as standard epuipment. To
enable the timers, push the TIMER button on the remote. The yellow CYCLE LED will be lit.
To set the amount of time that the machine will make fog, adjust the FOG ON knob. To set
the delay between bursts, adjust the FOG OFF knob. The range of time for both FOG ON
time and FOG OFF time is 2-120 seconds.
NOTE: The numbers indicated by the FOG ON and FOG OFF knobs are relative and should
be used for reference only.
7. DAISY CHAIN (OPTIONAL)

ROSCO MODEL 1750 Page 5 01/06
www.rosco.com
The Rosco Model 1750 has the capability to control up to 4 machines from a single controller.
In this “Daisy Chain” process, the machine that controls the others is called the MASTER and
the others are called SLAVES. Make sure that a remote control is attached to the MASTER
machine as outlined in Step 2 and all remote controls are removed from all the SLAVE
machines. Connect a cable with 6-pin XLR connectors to the socket on the rear of the
MASTER machine and connect the other end to the remote connection on the first SLAVE
machine. Repeat the process from the first SLAVE machine to the next. As many as 4
machines may be operated from a single remote. Operate the remote as outlined in Steps 5
and 6 above.
8. DMX REMOTE (OPTIONAL)
The Rosco Model 1750 has the option to be operated from a lighting control console that uses
a DMX signal. Attach the DMX remote as outlined in Step 2 above.
Attaching DMX cable: Plug a standard 5-pin DMX cable in the connection marked DMX IN
on the remote. Note that the DMX can pass through to another device by plugging another
cable into the DMX OUT plug. Note: Like any DMX controlled device, if the Model 1750 is
the last device in the DMX line then a terminator plug must be plugged into the DMX OUT
connection
Setting the address: To set the DMX address, use the dip switches located on the DMX
interface. The dip switches are based on the binary system, so the channel number must first
be converted to a binary number. (See illustration on page 6.). When the dip switch is in the
down position, it is “on”. When there is a valid DMX signal, the DATA LED next to the dip
switches will light. NOTE: The Rosco Model 1750 uses one DMX channel.
Operating the unit: Operate the machine as outlined in Steps 1-4 above. When the proper
DMX channel is given a non-zero value, the machine will make fog. The fog volume will be
proportional to the value of the channel setting.
Manual Override: If desired, the local controls on the remote can be used to override the
DMX signal.

MAINTENANCE
1. The main fuse of the ROSCO MODEL 1750 smoke machine is located on the circuit card
inside the machine. NOTE: Be sure to check the specifications when replacing any fuses.
WARNING: DISCONNECT THE ROSCO MODEL 1750 FROM POWER BEFORE
CHECKING OR REPLACING THE FUSE. FAILURE TO DO SO COULD BE
HAZARDOUS AND RESULT IN AN ELECTRICAL SHOCK.
2. After every operation, only after the machine has cooled, it should be wiped with a clean
damp cloth or paper towel. This practice prevents the build up of dirt and dust which may
enter the machine and damage sensitive internal components. Do not use solvents for
cleaning.
3. Before and after the machine is stored for an extended period, the machine should be
properly cleaned. The best method for cleaning is using de-ionized water only. To flush the
machine, turn it on and, when ready to use, put the fluid pick-up tube into a container of de-
ionized water. Run the water through the machine and flush for three minutes. The machine
should be immediately turned off.
4. During use, operation of all switches and indicator lights should be monitored. Lights that
blink or flicker when they should be on or off, for example, are an indication of problems in
the machine's circuitry.
FOG DISTRIBUTION
The fog distribution in an enclosed area depends on air flow and temperature. Natural air
movement, air conditioning and other ventilation systems will affect movement of the fog.
Test under realistic conditions before using. If a space must be filled very quickly, move the
machine up and down and side to side. To conduct fog to particular areas, use a hose adaptor
and ducting hose (see OPTIONAL ACCESSORIES). Make sure that there is an air space of
2-3 inches between the nozzle and any ducting hose. Do not use ducting hose smaller than 4
inch diameter. The ROSCO MODEL 1750 works properly only in a horizontal position. Do
not tilt the machine during operation.
