3.3 Condensate drain (optional) If the Mistral MDX is used for heating only, a condensate drain is not necessary. Type MDX 33 MDX 56 Condensate kg/h Indoor air temperature 27°C and 50% humidity 3.3.1 Condensate drain with natural progression The condensate drain must meet the criteria as described in the manual of the outdoor unit.
The air diverter plate becomes dirty over time, which affects the functioning. The plate should be cleaned annually or more often if necessary. The Mistral MDX 33 has one diverter plate, the Mistral MDX 56 has two diverter plates. These two diverter plates are connected to each other shown in Figure 4.1.
