The booth feels warm or stuffy

Option 1 – QUATTRO 1.0

Before we start troubleshooting, here's a quick explanation of how the ventilation system in your QUATTRO works.

The ventilation system continuously refreshes the air inside the booth. Air is drawn in through the ventilation openings and released through the ceiling unit. This helps keep CO₂ levels stable during use.

Important: the ventilation system refreshes the air, but it does not actively cool it. Only an air conditioning system can lower the temperature.

If the booth feels warm, this is usually caused by heat generated by people, laptops, monitors, and other devices inside the booth.

When developing the QUATTRO, special attention was paid to maintaining stable CO₂ levels. Normally, CO₂ rises slightly at the beginning of use and then stabilizes at a level only slightly above the surrounding environment.

If the ventilation system is not working correctly, air can no longer circulate properly. As a result, heat builds up and the air may start to feel stuffy.

Please check the following:

Is the ceiling ventilation working?

On this version of the QUATTRO, both the light and ventilation are activated using the switch. Make sure the switch is turned on. Then place your hand near the ventilation grille in the ceiling unit and check whether you can feel airflow. If you cannot feel any airflow, please refer to the article covering ventilation failures.

Are all ventilation openings clear?

If ventilation openings are blocked, air cannot circulate properly. Check that nothing is covering the ventilation openings and that no objects are placed on top of the booth. If the QUATTRO is standing on a thick carpet, this may also affect airflow.

Is the QUATTRO used regularly?

The ventilation system only operates when it has been activated using the switch. If the booth has not been used for a longer period, leave the door open for a few minutes to allow fresh air to circulate inside.

Is the QUATTRO exposed to direct sunlight?

Direct sunlight can cause the booth to heat up. The ventilation system can only reduce this effect to a limited extent because it does not actively cool the air. If possible, move the booth to another location or avoid direct sunlight.

Do you still need help?

Were you able to identify the cause? Great. Is the issue still occurring? Please contact us via our contact form and we'll be happy to help you find a solution.

Option 2 – QUATTRO 1.1 to 1.5

Before we start troubleshooting, here's a quick explanation of how the ventilation system in your QUATTRO works.

The ventilation system continuously refreshes the air inside the booth. Air is drawn in through the ventilation openings and released through the ceiling unit. This helps keep CO₂ levels stable during use.

Important: the ventilation system refreshes the air, but it does not actively cool it. Only an air conditioning system can lower the temperature.

If the ventilation system is not working properly, heat and CO₂ can build up more quickly inside the booth.

Please check the following:

Is the ceiling ventilation working?

On this version of the QUATTRO, both the light and ventilation are activated using the switch. Make sure the switch is turned on. Place your hand near the ventilation grille in the ceiling and check whether you can feel airflow. If the airflow is weak or not noticeable, please also check the control unit behind the left ventilation grille. Follow these steps:

1. Disconnect the booth from power
   Unplug the QUATTRO before removing the ventilation grille.
2. Remove the left ventilation grille
   The control unit is located behind the left ventilation grille when facing the front of the booth.
3. Check the switch on the control unit
   There is a small switch on the control unit. Make sure it is set to the highest setting.
4. Reinstall the grille and test again
   Reattach the ventilation grille, reconnect the QUATTRO to power, and check again whether airflow can be felt at the ceiling unit.

If there is still no noticeable airflow, please get in touch with us here.

Are all ventilation openings clear?

Check that none of the ventilation openings are blocked. Also make sure nothing is covering the top of the booth. Thick carpets may also reduce airflow.

Is the QUATTRO used regularly?

The ventilation system only operates when it has been activated using the switch. If the booth has not been used for some time, leave the door open for a few minutes to refresh the air inside.

Is the QUATTRO exposed to direct sunlight?

Direct sunlight can cause the booth to heat up. The ventilation system can only reduce this effect to a limited extent because it does not actively cool the air. If possible, move the booth to another location or reduce its exposure to direct sunlight.

Option 3 – QUATTRO 1.6 and later

Before we start troubleshooting, here's a quick explanation of how the ventilation system in your QUATTRO works.

The ventilation system continuously refreshes the air inside the booth. Important: the ventilation system refreshes the air, but it does not actively cool it. Only an air conditioning system can lower the temperature.

If the ventilation system is not working properly, heat and CO₂ can build up more quickly inside the booth.

Please check the following:

Is the ceiling ventilation working?

On this version of the QUATTRO, the light and ventilation are activated automatically by a motion sensor. Enter the booth and wait a few seconds for the motion sensor to activate. Then place your hand near the ventilation grille in the ceiling and check whether you can feel airflow. If the airflow is weak or not noticeable, please also check the resistor cables on both sides of the booth. Follow these steps:

1. Disconnect the booth from power
   Unplug the QUATTRO before removing any components.
2. Remove the resistor cables on both sides
   Remove the resistor cables located on both sides of the booth.
3. Reconnect the booth and test again
   Reconnect the QUATTRO to power and check again whether airflow can be felt at the ceiling unit.

If there is still no noticeable airflow, please get in touch via our contact form.

Are all ventilation openings clear?

Check that none of the ventilation openings are blocked. Also make sure that nothing is covering the ventilation grille on top of the booth. Thick carpets may also restrict airflow.

Is the QUATTRO used regularly?

The ventilation system only runs while the booth is in use and the motion sensor is active. If the booth has not been used for some time, leave the door open for a few minutes to refresh the air inside.

Is the QUATTRO exposed to direct sunlight?

Direct sunlight can cause the booth to heat up. The ventilation system can only reduce this effect to a limited extent because it does not actively cool the air. If possible, move the booth to another location or avoid direct sunlight.
