TECHNICAL DATA

The unit is designed for indoor or sheltered use. The installation conditions must prevent ingress of atmospheric precipitations and direct solar radiation at the ambient temperatures from -35 °C up to +50 °C. Outdoor unsheltered mounting is allowed provided an extra cover and weather hoods are installed on the air ducts (not included in the delivery set).
The frost protection for the water drainage and connected pipelines must be provided during sub-zero ambient temperatures (if the unit is equipped with an air cooler). The heat medium temperature in the water heat exchangers (if available) must be sufficient to prevent their freezing. Hazardous parts access and water ingress protection rating:

• IP54 for the unit motors
• IP42 for the assembled unit connected to the air ducts without extra cover or weather hoods
• IP44 for the assembled unit with connected air ducts, extra cover and weather hoods (specially ordered accessories)
• IP00 for the unit not connected to the air ducts

The unit design is constantly being improved, thus some models may be slightly different from those described in this manual.
