INTRODUCTION
This manual offers a detailed explanation of the operation of the ROSCO DELTA HAZER.
To assure efficient and safe operation, please take a few minutes to read this material.
The ROSCO DELTA HAZER is a thermal aerosol generator designed for variable haze
output. It features the DELTA TECHNOLOGY™ which is a revolutionary electronics design
unmatched by any other fog or haze machine. DELTA TECHNOLOGY™ offers accurate
thermal control, precise pump speed as well as allowing the Delta Hazer to be operated:
manually; by timers; from a DMX lighting console; or a 0-10 volt signal.
The Delta Hazer is part of a system, the other basic component being Rosco Delta Haze
Fluid. They should always be used together. This unique fluid formulation is safe when used
according to instructions. It is water-based and contain no petroleum distillate. 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.
CAUTION: The Rosco Delta Hazer is designed to use ONLY the Rosco Delta Haze Fluid
and no other fluids, whether manufactured by Rosco or not, will function properly.
HOW THE MACHINE WORKS
When the heat exchanger has reached proper operating temperature, the operator switches
power to the siphoning pump, which draws the haze 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. In addition there is an internal fan
that helps disperse the particles to form a “haze” effect rather than a “fog” effect.
NOTE: The terms “fog”, “haze” and “smoke” are used interchangeably. However the
ROSCO DELTA HAZER does not produce smoke, but a mist or aerosol.

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 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 tempearture 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.

PAGE 5 www.rosco.com
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 three feet
(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 haze 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 DELTA HAZE FLUID OR
MODIFICATION OR ATTEMPTED UNAUTHORIZED REPAIR OF THE ROSCO
DELTA HAZER WILL IMMEDIATELY INVALIDATE THE WARRANTY.

GENERAL OPERATING INSTRUCTIONS
1. POWER HOOK-UP
Plug the power cord on the base unit into a socket rated at the proper voltage and amperage.
The machine requires a dedicated power circuit.
CAUTION: Do not plug the machine into a dimmer that is “parked” at full. Plug it only
into a wall socket or non-dim circuit.
2. REMOTE CONTROL
If it is not already plugged in, plug the remote control into the socket marked “Remote
Control” under the cover at the rear of the base unit. The green LED over the POWER button
should blink indicating that the Delta is receiving power. The Delta Hazer can ONLY operate
with a remote control attached.
Note: The remote attaches with standard computer Category 5 cable using an RJ-45
connection. 3. WARM UP
Push the button marked POWER on the remote. This will enable the electronics and the unit
will start to heat. Let the machine warm up for about three (3) minutes until the remote
indicates “READY”. The Delta Hazer is now ready to make haze as long as the remote
indicates that the machine is “READY” and there is fluid in the reservoir.
Fan and Air Compressor note: When the machine is first turned on, the fan inside the
machine will immediately start to operate even though no haze is being produced. In addition,
once the machine is fully heated, the internal air compressor will turn on. This is normal
operation.
4. FLUID DELIVERY
Place the bottle of Rosco Delta Haze 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.
Priming: If the Delta Hazer has not been used for a while, or has run out of fluid, it may be
necessary to “prime” the pump. To accomplish this, turn the Fog Volume knob to full and
enable the Fog switch. Run the machine at full until haze comes out the front.
Low Fluid Sensor: The Delta Hazer is equipped with a Low Fluid Sensor. When fluid
reaches a certain point in the bottle the remote will indicate that the fluid is running low. This
is simply an indication to the operator that the fluid level should be checked and will not
affect the performance.
Pump Cut Off: The Delta Hazer is also equipped with a thermal cut-off that is attached to the
pump. If the machine is running when the fluid bottle is empty, the pump could start to

PAGE 7 www.rosco.com
overheat at which time the thermal sensor will cut off power to the pump. Avoid running the
machine without fog fluid to prevent damage to the pump.
5. VOLUME CONTROL
When the volume control is changed (see below) BOTH the pump speed and fan speed are
sped up or slowed simultaneously.
CAUTION: The machine only works with uncontaminated ROSCO DELTA HAZE
FLUID. 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,
whether manufactured by Rosco or not, voids the warranty of the Rosco Delta Hazer.
DIGITAL/DMX REMOTE CONTROL
OPERATING INSTRUCTIONS
OVERVIEW
The DIGITAL/DMX REMOTE CONTROL is a sophisticated digital interface that allows the
the Delta Hazer to be operated: manually (MANUAL MODE); from timers (TIMER MODE);
from DMX control (DMX MODE); or from a 0-10 volt signal. The interface is a backlit
liquid crystal display (LCD) showing a series of commands. The interface allows the menu to
display in any of six languages (English, French, Spanish, Italian, Portuguese, and German).
In addition, it allows timers to be set in one second increments up to 10 minutes on and one

push the ENTER button. If you do not want to keep the timer settings, push an ARROW
button until “NO” is blinking and then push the ENTER button. The LCD will return to the
“SET TIMERS” display. New times can now be entered. Once the settings are saved and the
Operation Menu is displayed, the timer function can be turned on by pushing the TIMER
button on the remote. The yellow LED over the TIMER button will light indicating that the
Delta is in timer mode. When timers are no longer required, simply push the TIMER button
again. To adjust the volume in the TIMER MODE, turn the JOG WHEEL to the desired fog
volume.
Note: When “YES” is chosen in the “SAVE SETTINGS” submenu, the memory in the
DIGITAL/DMX REMOTE CONTROL will remember the settings even when the machine is
turned off or disconnected from a power source.
10. DMX MODE
The Rosco Delta Hazer has the option to be operated from a lighting control console using
USITT DMX 512/1990.
Attaching DMX cable: Plug a standard 5-pin DMX cable to the connection marked DMX IN
at the rear of the base unit. Note that the DMX signal can pass through to another device by
plugging another cable into the DMX OUT plug. Note: Like any DMX controlled device, if
the Delta Hazer is the last device in the DMX line then a terminator plug must be plugged
into the DMX OUT connection.
Setting the DMX address: With the Operation Menu displayed. push the ENTER button
until the “SET DMX” menu is displayed on the LCD. Push an ARROW button so that
“YES” is blinking. Turn the JOG WHEEL until the desired DMX address is displayed. Turn
the JOG WHEEL clockwise to display higher numbers and counterclockwise for lower
numbers. Note: After 512, the channels will go back to 1 so when going from a low number
to a high number, the JOG WHEEL can be turned counterclockwise.
Saving the DMX address: When the desired channel is displayed push the ENTER button
and the LCD will display “SAVE SETTINGS”. To keep the DMX channel settings push an
ARROW button until ”YES” is blinking then push the ENTER button. If the DMX channel
settings are not to be kept, push an ARROW button until NO is blinking. Once the DMX
address is saved, the Delta Hazer will automatically be set to run from DMX.
Operating the unit: With the Operation Menu displayed and the Delta Hazer in DMX mode
(see above), turn the machine on at the remote by pushing the POWER button. Once the
remote reads “READY” and the Delta is in DMX mode, the unit will receive signals from the
lighting console. When the selected channel has a non-zero value at the light board, the Delta
will make fog. The percentage reading at the light board corresponds to the output. (i.e., if the
channel at the light board is set at “75%”, the Delta will run at a volume of 75%.) To stop the
haze, set the channel to zero. The selected channel can be written into any cue.
IMPORTANT NOTE: While in DMX Mode the Delta Hazer can also be operated manually
or, if timers have been set, in the Timer Mode. The Timer Mode will supersede the DMX
Mode and the Manual Mode will supersede the Timer Mode. When “YES” is answered to the

PAGE 10 www.rosco.com
“SAVE SETTINGS?” message, the Digital DMX Remote will only remember the last
settings and will erase any previous settings. To set timers and DMX, both settings must be
entered and then the settings should be saved.
ANALOG/DMX REMOTE CONTROL
OPERATING INSTRUCTIONS
OVERVIEW
The ANALOG/DMX REMOTE CONTROL is an analog interface that consists of an array of
switches and knobs. These allow the Delta Hazer base unit to be operated: manually; from
timers; from DMX control; or from a 0-10 volt signal. The timers will allow production of fog
for up to 2 minutes with intervals of up to 4 minutes between bursts. It also has a series of
rotary switches to set the DMX channel. In addition, the ANALOG/DMX REMOTE
CONTROL has LEDs that indicate when the reservoir is running low on fluid or when there
is a DMX signal.
11. INITIAL OPERATION
Follow steps 1-4 above. When first powered, the red LED marked “HEATING” will light
indicating that the Delta is heating up. Let the machine warm up until the green “READY”
light is lit. Note: The ANALOG/DMX REMOTE CONTROL will indicate that the fluid
container is low on fluid with a red LED marked “LOW FLUID”.
