Chapter 1 – Air Cleaning Systems and Indoor Air Quality
State-of-the-art ltration technology
Your IQAir advanced air cleaning system has been developed especially for the control of specic gaseous
components. Thanks to advanced gas cartridge (GCX) lter technology, each model of the IQAir GCX Series has been
optimized for the control of specic gaseous pollutant groups. The following model congurations are available:
•IQAir® GCX VOC for the control of volatile organic compounds
•IQAir® GCX MultiGas for the control of volatile organic compounds and many inorganic compounds
•IQAir® GCX Chemisorber for the control of many inorganic compounds and some organic compounds
•IQAir® GCX AM for the control of ammonia and amines
1.1 Improving Indoor Air Quality
Air cleaning can play an important role when it comes to improving indoor air quality. However, it should be noted
that air cleaning should be used in conjunction with pollution source control and ventilation, wherever possible.
Strategy to improve indoor air quality
To tackle any indoor air quality problem, keep the following three-step strategy in mind:
1. Eliminate or reduce the air pollution source as much as possible. Source control is by far the most effective way to
improve indoor air quality, since it sets out to deal with air pollution at the point of origin.
2. Ensure that sufcient fresh air is entering the room from outside. Air cleaners are not a substitution for sufcient
ventilation. They are not able to reverse the conversion of oxygen (O2) into carbon dioxide (CO2), caused by
breathing and combustion processes.
3. Ensure the IQAir® system can clean enough air to cope with your room size. The actual hourly air volume cleaned
by the system should be at least double the air volume of your room. If the rate at which pollutants enter the room
air is high or the indoor air quality requirements are stringent, the hourly air delivery of the system needs to
exceed the room air volume several times. To achieve that level of air turnover, it may be necessary to employ
more than one IQAir system, or consider an IQAir whole-house system.
Air Cleaning Results
Although air cleaners may be advertised and sold to be suitable for use in specic indoor environments and to deal
with specic indoor air quality problems, the manufacturer and distributors make no claim as to the specic air
cleaning results that are achieved under the user’s individual operating conditions. The air quality improvements
that can be realized with the IQAir® system (as with any air cleaner) in indoor environments depends to a signicant
degree on circumstantial factors, which are out of the control of the manufacturer or distributors. Important factors
which will inuence the air quality improvements that can be achieved in an indoor environment with an air cleaner
include:
•Type of air pollutants present
•Intensity of the pollutant source(s)
•Pollutant concentration
•Size of the indoor environment (room size)
•Operating speed of the unit
•Number of air cleaners placed in the indoor environment
•Saturation state of the lters in the air cleaner
Consult a qualied specialist to determine an effective and comprehensive indoor air quality strategy.

2.2 Choosing a Suitable Location
When choosing a suitable location for the
IQAir system, keep the following considerations
in mind:
•Choosing the most suitable room for the
system will depend on where you would
like the focus of the air cleaning efforts. Two
main considerations are the time you spend
in a particular room and the location of the
main air pollution sources. As a general rule,
the closer the system is located to the air
pollution source, the better the air cleaning
performance in the room.
Although an air cleaning result may be
achieved in adjacent rooms, the main air
cleaning will take place in the room where
the system is located. For the best air
cleaning results in adjacent rooms, make
sure that doors to these rooms are left wide
open.
•For best performance, the system should be positioned at least 12 inches (1 foot) away from the nearest vertical
surface, such as a wall or a cupboard. In general, the more centrally the system is positioned, the better the
performance.
•Position the system close to a power outlet and make sure that the power cord is positioned in a way that it does
not present an obstacle.
•Make sure that the system is positioned in such a way that the control panel is easily accessible.
2.3 Connecting to Power
1. Plug the connector end of the power cord into the recessed power inlet socket on the back of the system.
2. Plug the other end of the power cord into a power outlet or power strip.
Important: The only way to disconnect power completely is to unplug the power cord.
Do not use the IQAir® system when the power cord becomes damaged. The power cord may be replaced with an
approved cord with a two-pole plug. These power cords are commonly used for computers and similar appliances.

Chapter 3 – System’s Components
Chapter 3 – The IQAir® System’s Components
3.1 Description of Housing Components
The IQAir® system features a modular tower design in which all important ltration and air moving components are
positioned vertically in-line, i.e. stacked on top of another. Air is drawn into the system at the base, and passes
through several lter stages to be returned to the room via the diffuser on top of the system. The housing modules
are held together by two locking arms.
•The Locking Arms hold the housing elements together. When opened, the locking arms allow easy access to all
filters.
•The Handle on top of the diffuser is designed for carrying the IQAir system.
•The EvenFlow™ Diffuser features an omni-directional horizontal air outlet.
•Frame 3 to 5 surrounds the 4 gas phase cartridges and filter sleeves to where the diffuser starts.
•The Filter Module 2 consists of frame 2 and a steel base plate in which the four gas phase filter cartridges are fixed
by means of a bayonet locking system.
•The Fan Assembly comprises two housing modules with the centrifugal fan inside.
•The Filter Module 1 consists of frame 1 and the particulate pre-filter which is secured inside the frame by several
filter clamps.
•The Base with its arched design features air intake openings on two sides.

Chapter 3 – System’s Components
1. Room air is drawn into the system via two arched openings at the
base.
2. The air is drawn in through a high-efciency pre-lter that removes
most pollution particles.
3. At the heart of the system, sandwiched between the lters, is a
powerful centrifugal fan which generates the airow.
4. The air is pushed through four steel cartridges that contain up to
31 lbs. of gas phase control media, which retains specic gaseous
pollutants.
5. Particulate post-lter sleeves hold back abrasion particles from the
gas phase lter media.
6. Low turbulence, low velocity air is returned to the room via the
EvenFlow™ diffuser.
3.2 Description of Removable Components
The IQAir® system features a modular housing design which enables the easy replacement of all lter elements in a
matter of seconds. The illustration below shows all the removable components. For more details on how to replace
lters, please refer to Chapter 6 – Replacing Filters.

Chapter 4 – Using the Control Panel
4.1.1 Description of Control Panel Keys
Power Key
The Power key switches the IQAir® system on and off. When the system is switched off, the fan stops to run, but the
system will remain connected to the power supply (standby mode). The standby mode allows for automatic timer
start-up. In the standby mode, the different menu functions can be accessed.
Tip: In a menu window, the Power key also serves as a quick exit key to return to the main display window.
Arrow () Key
When the system is switched on, the key allows the adjustment of the fan speed. In the enter mode, indicated by
the appearance of a black ashing cursor (see“Enter Key” below), the key is used to modify the selected setting in
the display window. Conrmed with the Enter key, the enter mode is automatically terminated. The LCD will then
display the current menu settings for another 15 seconds before reverting to the main window display.
Chapter 4 – Using the Control Panel
The IQAir® system is operated and controlled via the electronic control panel which is located at the top of the front
locking arm.
Several operations can be completed via the electronic control panel:
•Switching the system on and off
•Controlling the fan speed and corresponding air delivery rate
•Checking the remaining lter life of the individual lters
•Setting the automatic timer
•Resetting the Filter Life Monitor after replacing a lter
•Locking the control panel to avoid tampering with the system’s settings

Menu Key
The Menu key allows access to any one of ten menus. Pressing the Menu key once allows access to the rst menu
function. Pressing the Menu key twice allows access to the second menu function, and so on. If no key is pressed for
15 seconds in a menu window, the display will revert to the main display window. Tip: If you are in a menu window
and would like to remain in the window for more than 15 seconds, keep the key depressed.
Enter Key
The Enter key, if pressed for 3 seconds, allows the modication of a setting. The enter mode is indicated by a ashing
cursor on the modiable setting. Pressing the Enter key again will save any entry and move the cursor to the next
modiable item in the display window. When the last modiable choice in a window is conrmed with the Enter key,
the enter mode is automatically terminated and the new settings are saved.
Filter Life LEDs: Whenever the system is on, the color of the lter life LEDs (light emitting diodes) indicates the state
of the individual lters in the system. Note: The positions of the lter life LEDs on the control panel correspond to
the actual positions of the lters within the system.
The lter life indicator LEDs signal four possible stages in the life of the lter:
1. Green: The lter is still within 80% of its estimated life span.
2. Orange: The lter is approaching the last 20% of its estimated life span.
3. Red: The lter has reached the end of its estimated life span.
4. Red blinking: The lter has passed its estimated life span and should be replaced immediately. The IQAir®
system’s effectiveness is likely to have been reduced dramatically, either due to a reduction in
airow (particle lters are clogged) or a reduction in lter efciency (gas phase lter is saturated).
Fan Speed LEDs: These LEDs simulate the fan speed through the frequency of their rotation. The faster the rotation
of the fan speed LEDs, the faster the actual fan speed of the unit.
4.2 Control Panel Locking Function
The control panel keys can be locked to avoid tampering with the
settings. To lock or unlock the control panel keys, both the Menu and
the Enter key have to be pressed down simultaneously for 3
seconds. The activated locking function is indicated with a star
symbol in the control panel display.
4.3 Fan Speed and Air Delivery
The IQAir® system can be set to run at six different fan speeds, which correspond to six different airow rates. Speed
1 is the lowest speed. Speed 6 the highest fan speed. The higher the fan speed, the more room air will be ltered by
the system. The high fan speed settings provide additional air cleaning power to deal with situations of elevated
pollution levels.
To allow better evaluation of the system’s performance at different fan speeds, the standard display window shows
not only the fan speed, but also the air delivery rate (airow). The displayed airow is factory preset and is not
measured by the system itself. (When timer is activated, the display will change. Refer to section 4.4.6)
4.3.1 Regulating Fan Speed
1. When the IQAir® system is switched off (standby mode), the rst line of the
LCD display shows the model name. To switch the system on, press the
Power key on the far left of the control panel.
2. The LCD now displays the fan speed and the corresponding airow rate.
Note: The system starts at the fan speed at which it was running when it
was last used.
3. To change the fan speed, press the key.

4.3.2 Air Exchange Rates in Differently Sized Rooms
Any air cleaner can only be effective if it lters a sufcient amount of air in an indoor environment. For general air
cleaning purposes, the IQAir® system should be able to lter the room air volume at least twice every hour on the set
fan speed to achieve a signicant air quality improvement. If the intensity of the pollution source is high or a high
degree of purication is needed, more air changes may become necessary. In order to achieve the desired number
of air changes, more than one air cleaner may be required.
The number of air changes that are necessary to attain a certain level of indoor air quality will depend on a variety
of factors, including:
•Intensity of air pollution source: The higher the rate at which air pollutants are produced or enter the indoor
environment, the higher the air cleaning rate in the room needs to be.
•Filtration efciency for specic air pollutants: The lower the ltration efciency for certain pollutants, the more
air changes are required to reduce these pollutants.
•Desired improvement in air quality: The higher the desired improvement in air quality, the more air changes are
required.
The number of air changes per hour (ACH) produced by an IQAir® system in a specic environment are calculated
as follows:
hourly air delivery of the IQAir® system (cfm) x 60 = air changes per hour (ACH)
air volume of the room (cu.ft.) (L x W x H)
Note: The air delivery rates of the IQAir® system at the various fan speeds settings are listed on the “Technical
Specications” sheet included at the back of this manual or at the IQAir website www.iqair.com.
Example calculation: A room with the dimensions of 13 x 14 x 8.5 ft. has an air volume of 1,547 cu.ft. With an air
delivery rate of 140 cfm, the room air volume will be circulated over 5.4 times per hour by the
IQAir® system (140 cfm = 8,400 cu.ft/h; 8,400 cu.ft/h ÷ 1,547 cu.ft = 5.43 ACH).
4.4 Using the Menu Functions
The IQAir® control panel offers a choice of several menu options which allow access to the advanced features of the
system. In total there are ten active menu functions. The functions can be accessed in standby or running mode.
4.4.1 Menu Overview
Pressing the Menu key accesses the menu functions in the following order:
1. Filter Life Monitor (Remaining Life)
Allows the viewing of the remaining lter life of the individual lters
within the system.
2. Setting the Timer ON period (Auto Timer)
Allows to activate the timer and set the Timer ON period.
3. Automatic Timer (Day-of-the-Week Timer)
Allows to deactivate the Timer ON period on certain days of the week.
4. Timer ON Speed Selection
Allows to set the fan speed for the Timer ON period.
5. Timer OFF Speed Selection
Allows to set the fan speed outside the Timer ON period.
6. Time & Day Setting
Allows to set the current time and day setting.

Chapter 4 – Using the Control Panel

4.4.2 Filter Life Monitor (Remaining Life)
The IQAir® system is equipped with an electronic Filter Life Monitor that calculates the remaining life of the system’s
lter elements. Thanks to the Filter Life Monitor, the user does not have to guess when lters need to be replaced or
replace them at xed intervals (which rarely correspond to the actual amount of use). The Filter Life Monitor keeps
track of the most important factors affecting the life of the individual lter elements. The Filter Life Monitor display
shows the remaining life of each individual lter at any given time.
1. To reach the Filter Life Monitor display from the main display window,
press the Menu key once. The remaining life of the Pre-Filter will appear.
2. Press the key to view the remaining life of the other lters in
the system.
3. The remaining life of the lter elements is expressed in hours of
operation at the current speed setting.
How the Filter Life Monitor Works
The basis for the calculation of the remaining lter life is the already elapsed operation time at the set fan speed. This
input is compared with an internal memory bank which contains information about the different lters’ lives under
specic conditions of use.
The Filter Life Monitor makes a calculation of the remaining lter life, taking into account not only past use of the
system, but also likely future use. As reference for future use, the Filter Life Monitor uses the fan speed which is set
at the time.
The relationship between the current fan speed and the remaining lter life displayed can be expressed as follows:
The higher the current fan speed setting, the shorter the displayed remaining lter life.
7. Filter Life Reset
Allows the resetting of the lter life counter after replacing a lter.
8. Airow Units
Allows to switch the airow units between cfm (cubic feet per minute)
and m3/h (cubic meters per hour).

Chapter 6 – Replacing Filters
The IQAir® system is equipped with a Filter Life Monitor which is designed to assist you in determining when a lter
needs to be replaced. If the air pollution in your environment is very high, there is a possibility that the lter may not
be effective throughout the displayed life time and may have to be replaced earlier than indicated by the Filter Life
Monitor.
For this reason, it is important to look out for the signs of used up lters and replace lters earlier if necessary. The
main signs are:
•Increased operating noise
•Decreased airow
•Clogged lters
•Increased odor presence
Note: Whenever a filter is replaced, the filter life must be reset for the new filter.
Refer to section 4.4.8.
6.1 Location of the Filter Elements
The IQAir® system features a modular housing design which enables easy replacement of all
lters in a matter of minutes. The illustration of the IQAir® system on the control panel shows
the positions of the individual lters. These positions correspond to the actual positions of the
lters within the system.
