Any other type of ap- plication is considered as not conforming with the intended purpose and may lead to deviating results being displayed by the Condair Cube. Any warranty claim will be voided if the device is not used for its intended purpose. Intended use also includes observing all the information contained in this manual. Prohibited�modifications�to�the�unit No�modifications�must�be�undertaken on the Condair Cube without the express written consent of the manufacturer. For the replacement of defective components only use original accessories and spare parts available from your Condair representative.

the cavity on the lower, left side of the cube (see product overview). Note: When the Condair Cube is plugged in via the USB cable, it switches on automatically. Fully charge the device before using it for the first time. 2. Place the Condair Cube upright in the room where you want to check the room air. The Cube must be placed as shown in the figure below, so that the sensor on the back of the Cube is reached by the room air and the excess heat can escape through the ventilation slots.  3. Once the Condair Cube is in place, it requires an adjustment time of ap- prox. 20 minutes until all values are displayed correctly. In particular, the temperature may deviate during the first phase after switching on, since the sensor is not yet at operating temperature. 4. When the Condair Cube is put into operation for the first time, it must be calibrated. This procedure is described in chapter 5.

of a traffic light system: Green – Healthy (Everything in the optimal range) Yellow – Acceptable (Caution: Need for action) Red – Critical (Critical readings) CO2 Green circle: CO2 content of the ambient air is optimal. (value is ≤ 800 ppm) Yellow circle: CO2 content in the ambient air is increased. Ventilation recom- mended. (value is between > 800 and ≤ 1200 ppm) Red circle: CO2 content in the ambient air is critical. Ventilation necessary. (value is > 1200 ppm) Relative humidity Green circle: Relative humidity of the ambient air is at an optimum. (value is between ≥ 40 and ≤ 60 % rH) Yellow circle: Relative humidity of the ambient air is rather low or rather high. (value is between ≥ 30 and < 40 % rH or > 60 and < 70 % rH) Red circle: Relative humidity of the ambient air is too low or too high. (value is < 30 % rH or ≥ 70 % rH) Temperature Green circle: Comfortable ambient temperature. (value is between ≥ 20 and < 23.5 °C) Yellow circle: Ambient temperature is rather low or high. (value is ≥ 17 and < 20 °C or ≥ 23.5 and < 27 °C) Red circle: The comfortable temperature range is undershot or overshot. (value is < 17 °C or ≥ 27 °C) Note: Please note that the sensor requires an adjustment time of up to 20 minutes after switching on, a reset or when moving to a different location, until the temperature reading is displayed correctly.

The ranges "healthy, "acceptable" and "critical" are distinguished. The aim is that the current measured value (red point) of the room air is in the inner green diamond and thus in the "healthy" range. In the upper area of the view, the currently measured CO2 content of the room air is displayed in a bar view. If the current measured value is outside the green range, the room should be ventilated to reduce the CO2 content in the room. Note: If the currently measured value is displayed as a gray dot at the edge of the diagram, it indicates that the measured value is outside the displayed range.

For every 10 minutes of measurement, a bar is displayed which shows the average value measured. This is colored according to the described traffic light system. See chapter chapter 4.2.1. If the bar is yellow or red, the temperature was too low or too high on average over the last 10 minutes, taking the health chart into account. A 4-hour chart is available for all measured values of CO2, temperature and humidity. These views are accessible via the arrow keys on the side of the circle. 4.3.3 Settings CO2 10:15 21.08.2021 85% Alarm settings Calibration CO2 Time and date settings Via the 3 icons you can call the different submenus: – Alarm settings – Calibration CO2 – Time and date settings Tap once on the respective icon to enter the submenus.

calibrated regularly. Two different calibration options are available: – Auto calibration – Manual calibration 5.1 Manual Calibration To calibrate the sensor manually, proceed as follows: 1. Menu → Settings → Calibration CO2 CO2 10:15 21.08.2021 85% CO2 CO2 Manual Auto 2. Place the sensor outdoors, for example outside the window in fresh air. Outside air is used as a reference, since it normally has a value of ap- prox. 400 ppm. Start 10:15 21.08.2021 85% 3. Press "Start" to start calibration.

If it is within the range of 400 +/-25 ppm, the calibration was successful. If the value is above or below this, repeat the calibration. Important: The sensor must be calibrated during the first start-up. Also, if you place the Cube in a new geographical location, it must be recalibrated for accurate measurement results.

value independently. It is important here that the sensor is in operation as permanently as possible and is exposed to fresh outside air at least once a week (approx. 10 min). During auto-calibration, the lowest measured value over one week is taken as the reference value and recalibrated to 400 ppm. Note: This setting is also saved when the cube is switched off. 1. Menu → Settings → Calibration CO2 2. Auto calibration 3. Enable or disable auto calibration If the Condair Cube is not operated permanently, it is recommended to deactivate the auto calibration and to perform a manual calibration when using the Condair Cube.

6 Time and date setting The Condair Cube has an internal RTC (RealTimeClock) which is used for the time and date display. Time and date run for approx. 2 months when the unit is switched off and without charging the Cube. Afterwards, both must be reset. Follow the procedure below to reset the time and date: 1. Menu → Settings → Time and date settings CO2 10:15 21.08.2021 85% 2. Set the desired time using the up/down arrow keys. The time format is defined as follows: hh:mm:ss (Hours:Minutes:Seconds) Ok : : 10:15 21.08.2021 85% 10 15 33 3. Confirm the entry with "Ok".

4. Enter the desired date in the next screen. The date format is defined as follows: dd:mm:yy (Day:Month:Year) Ok : : 10:15 21.08.2021 85% 21 08 21 5. Confirm the entry with "Ok" to complete the date entry.

the Cube. If a memory card is detected during the start-up process, the measured values are saved to the memory card every minute. With the help of Excel, this data can be displayed and analyzed. Recommended memory card: SANDISK microSDXC 16GB+AD memory card (16 GB, 98 MB/s, grey/red) or similar. 7.2 Power bank To extend the battery life of the Condair Cube, you can use any power bank with a 5V USB connection. 7.3 Display on large screen It is possible to connect the Condair Cube to an external monitor via a PC. To do this, connect the Condair Cube to the PC via the USB cable and install the necessary drivers. Then open the Condair Cube Tool to start the display on an external monitor. The values are updated at intervals of 30 seconds. Note: The minimum resolution for correct display of the values is 1024x768. Note that individual setting of zoom factors may have the negative effect on the display.

dispose of the individual components in accordance with local regulations at the authorised collecting point. If you have any questions, please contact the responsible authority or your local Condair representative. Thank you for your contribution to environmental protection.
