The sturdy steel housing is self-supporting and features an electrostatically applied polyester coating for optimal protection against corrosion. A set of vibration dampers is also included.

2 to 3 indoor units can be connected to this outdoor unit. The power of each individual indoor unit must not exceed 5.3 kW. Maximum rated cooling capacity (sum of the indoor units) must not be more than 9.6 kW (index 33). If connecting more than 100%, the cooling capacity increase is no longer linear. Simultaneous cooling and heating with different indoor units is not possible.

The outdoor unit features a BLDC fan motor for additional energy savings. The new axial fan has a curved front edge and ribbed back edge. This ensures high efficiency with minimal noise and a large fan blade width. A high airflow rate and improved fan efficiency is also achieved.
The motor is protected by thermal contacts to prevent overheating. The new grille shape on the outdoor unit improves airflow such that the efficiency of the heat exchanger is optimised and noise emissions reduced.
