No, not all bathroom fans are suitable for ceiling installation. Flexit recommends ceiling installation only for bathroom fans designed for Ø125 mm ducting. These models are engineered to ensure correct airflow, safe installation and stable operation when mounted in the ceiling. Other models are designed for wall installation and must not be installed in the ceiling.

Yes, an older Flexit central vacuum unit can easily be replaced with a model from the CVR series. CVR central vacuum units are designed to be well suited as replacements for older Flexit units, making the replacement simple and limited in scope.

Yes, it is possible, but it depends on the type of humidity-controlled fan you have. Humidity-controlled fans with a timer, often referred to as TH models, can be connected to an external on/off switch between the L and LT terminals, as described in the user manual. When the switch is on, the fan will run continuously. When the switch is off, the fan will only activate automatically at high humidity levels via the humidity sensor. This provides flexibility between manual and demand-controlled ventilation. It is important to note that humidity-controlled fans with timers are designed for demand-controlled operation, not for continuous long-term use. If continuous ventilation is required, we recommend using a fan designed for this purpose, such as Flexit Pro7 or Flexit Vario. These models offer lower energy consumption, lower noise levels, and are suitable for continuous operation.

No, Nordic units cannot be installed outdoors. Flexit residential units are designed for indoor installation and are not intended for outdoor environments with cold temperatures, moisture, and weather exposure. For proper operation and long service life, the unit must be installed indoors in accordance with the installation manual.

Yes, Flexit units can be connected to smart home systems. The unit can be controlled via digital inputs, allowing external signals from the smart home system to manage functions such as changing operating modes or activating boost ventilation. For more advanced integration, the unit can also be controlled and monitored using Modbus communication, either Modbus RTU or Modbus TCP, depending on the unit model. If you are an end user and need assistance with setup or integration, we recommend contacting an authorised service partner or the retailer where the product was purchased.

Yes, Flexit can act as the responsible designer for ventilation systems in project class 1 and 2. This applies to projects where the scope and complexity fall within these project classes and where Flexit’s delivery and professional area of responsibility are clearly defined in the project.

Yes, you can open the window and ventilate the bedroom. The ventilation system is designed for normal operation, but it is completely unproblematic to ventilate extra when needed, for example for rapid air exchange or personal comfort.

Yes, you can use a hose kit with an on/off switch for your CVR central vacuum unit. For the switch to function, the hose kit must be connected using a low-voltage control cable. Flexit offers hose kits with an on/off switch that are adapted to the CVR series and ensure correct and reliable operation.

Yes, the motor in central exhaust units of type ULV, USV and USVX can be replaced by the user. The motors are supplied with quick connectors, which makes replacement easy without the need for special tools. It is important to ensure that the unit is completely disconnected from the power supply before starting the work, and that the motor is installed correctly in accordance with the applicable instructions.

Yes, you can replace the central vacuum unit and use existing equipment, provided that it is Flexit equipment from a previous installation. In that case, the components are normally compatible, and you only need to replace the central vacuum unit itself.
