This unit was previously advertised and labelled with a 3.5-star energy rating.
After further testing, it was found that this unit, in fact, had a 4-star energy rating.
The listing and label has since been amended to accurately state the 4-star rating, but don't worry if your unit also has the 3.5-star label - it's actually 4-star, meaning that it has a better energy rating than previously listed!
