Ice Fog User Guide - June 2002 2
Congratulations!
You are now in possession of a MDG Low Fog Generator.
The ICE FOG QQ
QQ
QTM
This Generator produces a very dry and dense low-lying fog using refrigerated liquid Carbon
Dioxide (CO2) as a coolant and propellant as well as the MDG Low Fog Fluid
We hope it will bring you long hours of satisfaction. This product is available in many versions to
satisfy the needs of our professional users.
PLEASE READ THE FOLLOWING INSTRUCTIONS CAREFULLY AND
COMPLETELY BEFORE FILLING YOUR GENERATOR
WITH FOG FLUID AND TURNING IT ON.
MDG is a company globally recognized as the leader of the fog production industry.We design and
manufacture the most reliable fog/haze generators since 1979 and, we continue to impress the enter-
tainment and industrial market with unmatched innovations. Safe, non-toxic fog can be generated
from a discreet haze to a sustained, overwhelming intensity.
BASIC DESCRIPTIONS
The ICE FOG QTM was designed with safety and reliability in mind. They are capable of generating
pure white low fog for as long as you want (100% duty cycle) at full volume.
The ICE FOG QTM is a variable output Low Fog Generator capable of generating large volumes of
very dense low fog in a short period of time and also the most silent one on the market.
At the heart of the MDG Generators is an electronic assembly that keeps the heating module(s) at a
very stable temperature, which integrates three types of fail-safe systems. Those three types of
electronic fail-safe systems are designed to protect against over and under-heating conditions and,
against component failure.
The temperature is maintained within a narrow margin (the HEAT yellow LED turns on & off from
time to time to indicate the control of temperature) otherwise, an error condition will result and the
Low Fog Generator will shut down. When one of the safety systems is activated, the HEAT yellow
LED will start blinking indicating the fail mode. Shut down the main power switch, wait 3 to 4
minutes and retry the generator. If the fail mode still appears, unplug your generator and contact a
MDG authorized service centre for verification.
When an under-heating condition occurs, the generator will stop producing fog until the temperature
of the heating module is back within parameters.

SETTING UP
WARNING:
•When not in use ALWAYS switch off the power switch located on the back panel,
or unplug the generator.
•Never install above people.
•This Fog Generator must be installed in an upright position on a stable and leveled
surface.
•Use in a well ventilated area.
Maximum Operating Pressure: 414 kPa / 4.1 bar / 60 psi.
LIQUID & GAS REQUIREMENTS
WARNING – In the European Community the gas cylinder and regulator must be
compliant with the Pressure Vessel Directive. In North America the gas cylinder must be
manufactured, inspected and tested in accordance with U.S. Department of Transportation
(DOT) 3AL and Transport Canada (TC) 3ALM requirements.
Attention: Only use low pressure refrigerated liquid Carbon Dioxide (CO2) Dewar
container. The recommended pressure should be 1500 kPa (225 psi) ± 10%.
Caution: To prevent liquid and or gas leaks and drop of pressure, ALWAYS use a
neoprene washer when connecting the hose to the Dewar.
The CO2gas is used as a propellant when generating Fog. Output pressure can be
adjusted by mean of the CO2gas regulator that you will find in the back panel of the
generator.
FILLING OF THE FLUID RESERVOIR
WARNING – Use only MDG Low Fog Fluid. No doing so will damage the generator
and will void the warranty.
CAUTION:
•DISCONNECT UNIT BEFORE ADDING FOG FLUID
•DEPRESSURIZE THE FLUID RESERVOIR BY TURNING OFF
THE PRESSURE SWITCH LOCATED ON THE BACK PANEL OF
THE GENERATOR
To fill the fluid reservoir, unscrew the brass closure and pour the MDG Low Fog Fluid
until it reaches the inside bottom of the opening. Avoid overfilling, screw back the clo-
sure and make sure it is hand tightened.

OPERATING INSTRUCTIONS
The MDG Low Fog Generators are quite easy to operate and require no preventive main-
tenance. They are supplied with a removeable remote control. A DMX Interface can be
purchased as an option.
When the MAIN POWER 230 or 208 VAC and the MAIN POWER SWITCH is applied,
the generator is placed in stand-by mode. When in stand-by mode, most of the electronic
controls are off (except for the three types of fail-safe systems), waiting for the ON switch
on the remote control to be activated.
When the ON switch is pressed, the red LED indicating that the unit is working will lit, as
well as the yellow LED called HEAT, indicating the start of the heating cycle which will
last approximately 10 minutes. When the temperature reaches a pre-adjusted level called
the READY level (indicated by a green LED), the HEAT yellow LED will turn off.
The generator is ready to produce fog. Adjusting the working pressure of the CO2gas
regulator can control the amount of the fog emission.
When an overheating condition is detected, or if the internal temperature reaches 60°C
(140°F), a safety circuit is triggered. This circuit removes the power to the heating
elements, preventing hazardous conditions
The FOG ON signal (green LED) can be applied to produce low fog for as long as the
ready level is reached and all other control parameters are within specifications.
The 100% Duty cycle is continuous with specified line voltage, and will degrade with line
voltage loss. If that is the case, reducing maximum operating pressure can compensate it.
SHUT DOWN PROCEDURES
A Generator must never be shut down while making Fog. To power off a Generator the
following sequence must be observed:
· Always turn off the fog emission.
· Power off the Fog Generator (by switching off the “MAIN POWER SWITCH” or
by removing the MAIN POWER.
· If not use for a long period:
Always depressurised the fluid reservoir using the pressure switch found at
the back of the unit. (See picture on page 3)
· Close the liquid refrigerated CO2valve input of the dewar.
