3.4 OPERATION CONDITIONS
The unit can be used in rooms normal according to IEC 60364-5-51, resp.
ČSN 332000-5-51 ed. 3, ČSN 332000-1 ed.2. The ambient
temperature must be between -20 and +40 °C.
The unit can transport air without solid, fibrous, sticky, aggressive chemical and explosive additives. The maximum permissible supply air
temperature must not 40 °C. The maximum humidity of the air flowing through the unit is 17 g / kg s.v. (84 % r.h. at 25 °C).
If, due to the immediate climatic conditions, the humidity of the outdoor intake air reaches 100 % r.h. (wet steam), it is at the operator's discretion
whether to keep the unit running with the risk of temporary separation of moisture on the internal parts
of the unit (eg filters, flaps,…). This
humidity cannot be the subject of a complaint.
