Menu Key

The Menu key allows access to any one of eleven menus. Pressing the Menu key once allows access to the first 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 modification of a setting.The enter mode is indicated by a flashing
cursor on the modifiable setting. Pressing the Enter key again will save any entry and move the cursor to the next
modifiable item in the display window.When the last modifiable choice in a window is confirmed 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 colour of the filter life LEDs (light emitting diodes) indicates the state of the indi-
vidual filters in the system. Note: The positions of the filter life LEDs on the control panel correspond to the actual
positions of the filters within the system.

The filter life indicator LEDs signal four possible stages in the life of the filter:
1. Green:

The filter is still within 80% of its estimated life span.

2. Orange:

The filter is approaching the last 20% of its estimated life span.

3. Red:

The filter has reached the end of its estimated life span.

4. Red blinking: The filter 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
airflow (particle filters are clogged) or a reduction in filter efficiency (gas phase filter 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. The
locking function is cancelled by disrupting the power supply.

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 airflow rates. Speed
1 is the lowest speed. Speed 6 the highest fan speed. The higher the fan speed, the more room air will be filtered 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 (airflow). The displayed airflow is factory preset and is not
measured by the system itself.

4.3.1 Regulating Fan Speed

1. When the IQAir® system is switched off (standby mode), the first 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 airflow 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
