Yes, basic maintenance can be carried out yourself if you are reasonably technically inclined and know what needs to be done. What type of maintenance can be performed, and how it should be done correctly, is described in the user manual for your product. By following the user manual, you ensure correct execution and safe operation of the ventilation system.

Yes, in many cases the wall hood can be turned, provided this is permitted in the installation instructions for the specific model. It is important that the ducts are still connected correctly and that any drainage and function are maintained as described by the manufacturer. Installation must always be carried out in accordance with the applicable installation instructions to ensure correct operation.

Routines and recommendations for the use of low-profile duct systems are described in Flexit’s brochures and installation manuals for the relevant duct solutions. These documents provide the necessary information on correct design, installation and use. To assess whether low-profile ducts are suitable for your project, we recommend contacting Flexit for guidance based on the specific project conditions.

If the 3-speed switch 09257 is not working, you should check the capacitors inside the switch. Defective capacitors can prevent the switch from controlling the speed levels as intended. The correct run capacitor has article number 121840.

If the central vacuum does not start and you do not hear any clicking sound from the relay, this indicates that the start signal is not reaching the motor. In such cases, the control board is usually defective and must be replaced.

When the central vacuum starts and stops after a short time, this is often caused by partial or complete blockages in the ducting or hose. This restricts airflow, which can cause the motor to overheat. To protect the motor, the overheating protection will activate and shut down the vacuum. Check the hose and ducting for blockages and ensure free airflow before using the vacuum again.

Poor suction performance in a central vacuum system is often caused by partial or complete blockages in the ducting or hose. This may be due to accumulated dust, debris, or foreign objects in the system. It is recommended to check both the hose and the pipes for blockages and ensure free airflow throughout the entire system.

If a central exhaust unit of type ULV, USV or USVX does not operate at all speed levels, the most likely cause is a defective run capacitor. A local, authorised electrician can assist with replacing this component. The run capacitor has article number 101318 and is installed in the controller box near the motor.

If your ULV, USV or USVX central extract unit is making noise, this is usually caused by a dirty fan. The fan should be cleaned at least once a year.How to clean the fan: Unplug the unit from the special socket to make sure the fan is completely disconnected from power Carefully pull the connection box loose from the fan side. It is attached with Velcro Unscrew the four mounting screws on the round motor plate Pull the entire fan straight out of the fan housing while holding the square connection box Use a non-water-based degreasing cleaner together with a small scraper or brush to remove dirt from the fan wheel Be careful not to damage or squeeze the fan wheel Avoid getting liquid inside the motor Let the fan dry completely before reinstalling it in reverse order
