EcoNordic should be installed in a room without requirements for low noise levels and with access to a floor drain. The unit is therefore best suited for installation in a technical room. This ensures safe handling of condensate, reliable operation and good accessibility for service and maintenance.

Filters for Flexit ventilation units can be purchased directly through Flexit channels and selected retailers. To ensure that you choose the correct filter, we recommend using Flexit’s filter guide, where you can easily find the right filter based on your unit model.

Replacement motors for central exhaust units of type ULV, USV and USVX can be purchased from several Flexit distributors. Examples of online stores that stock these motors include Megaflis, Ventdel and Byggventilasjon.

A type E kitchen hood and a humidity sensor are connected via a three-core cable located on the top of the airhandling unit. Look for a black cable with three conductors. The brown and white conductors are used to activate the boost function, while the third conductor is normally not used. When contact is established between the brown and white wires, the unit will automatically switch to boost mode. This is typically used during cooking or when humidity levels are high. If you are an end user and not comfortable performing the connection yourself, we recommend contacting the service company that installed the system or the retailer where the product was purchased.

The pressure switch is connected using a three-core cable located on the top of the airhandling unit. Look for a black cable with three conductors. The green and white conductors are used for this function. When contact is established between the green and white wires, the unit will automatically increase the supply air flow. The third conductor is normally not used in this connection. If you are an end user and not comfortable performing the connection yourself, we recommend contacting the service company that installed the system or the retailer where the product was purchased.

The recommended maximum duct length depends on the duct diameter. For a 100 mm duct diameter, the recommended duct run is up to approximately 90 cm. For a 125 mm duct, the recommended duct run is up to approximately 5 metres. For a 150 mm duct, the duct run can be approximately 8–10 metres. Duct runs longer than recommended may result in reduced airflow and poorer performance.

Control cables for the control panel must be installed with a minimum distance of 30 cm from power cables. This requirement applies to Flexit ventilation units as well as the EcoNordic indoor climate unit. Correct cable separation helps ensure safe operation and reduces the risk of signal interference.

Flexit’s spare parts policy states that spare parts shall be available for a minimum of 10 years. In practice, we often have spare parts available for products that are significantly older than this. The goal is to ensure predictable operation, easier service, and longer product lifespan. Updated and more detailed information about spare parts is available on our website.

The noise level of a room ventilator varies between models and depends on factors such as fan speed and installation conditions. Sound levels are typically stated in dB(A) and measured at different operating modes. At low speed, the noise level is lower and suitable for bedrooms and living areas. At higher speeds, the noise level increases and is used when additional ventilation is required. Detailed sound data for each model can be found in the room ventilator brochure.

Flexit recommends that ventilation ducts are inspected every six years. During the inspection, the need for cleaning is assessed based on the condition of the ducts, usage and surrounding environment. It is not always necessary to clean the ducts at every inspection, but cleaning should be carried out when there is visible dust and dirt or reduced airflow. If needed, Flexit can help you find a qualified company to perform inspection and cleaning safely and correctly.
