How to optimally prepare the heat recovery unit for the winter season

It is important to properly prepare the heat recovery unit for the winter season because low temperatures and humid atmospheric conditions can significantly affect its efficiency and stability of operation. To ensure that the device will operate smoothly even in challenging weather conditions, it is necessary to carry out appropriate preventive actions and protections. Below are detailed guidelines that will help you properly prepare the unit for the winter season to ensure its stable and efficient operation.

In our ARIA VITALE device, we have implemented a three-stage anti-freezing protection system that automatically reacts to extreme weather conditions.

This system includes: • Activating the pre-heater to raise the temperature of the air entering the heat exchanger. • Adjusting airflow to prevent freezing and ensure stable unit operation. • Supporting the system with a bypass in case of extreme conditions.

Step 1: Checking the insulation of the ventilation installation Before the winter season arrives, carefully check if the air distribution installation is well insulated to prevent air losses and water condensation in the ventilation ducts.

Step 2: Checking the traps Check if the traps are properly connected and there are no leaks. Ensuring proper condensate drainage is crucial to prevent problems with excess water buildup that occurs during the winter season. Improper condensate drainage preparation leads to overflowing trays inside the units and improper operation of the entire system. To avoid this, the ARIA VITALE instructions include information on properly connecting traps depending on the unit’s operating position (wall-mounted, ceiling-mounted, floor-mounted).

Step 3: Condensate drainage and installation of the heat recovery unit in the attic If the unit is to be installed in the attic, make sure that the condensate is protected with a heating cable and appropriate insulation. Ensuring proper condensate drainage is crucial for the correct operation of the installation.

Step 4: Setting to minimal energy expenditure

During extreme frost periods (-15°C and below), consider reducing energy expenditure for ventilation units, if possible. This will allow for optimal unit operation with minimal power consumption.

Step 5: Regular maintenance Regularly maintain the unit, especially before the winter season arrives. Ensure that all components are in good working order and well protected from extreme weather conditions.

By strictly adhering to the above guidelines, you will be able to enjoy the stable and efficient operation of the ARIA VITALE unit even in challenging winter conditions. If you have any additional questions or concerns, please contact our service department.
