Before positioning please consider the overall dimensions and the technical space requirements of the system and the 
unit, electric and hydraulic connections and any air pipes/ducts or free passages. 
Neglecting these aspects may decrease performance and operational life of the unit and therefore increase the operating 
costs and maintenance. 
Units are designed to be installed 

INSIDE

 or 

PARTIALLY OUTSIDE

 (roof cover needed) and in fixed positions. 

 
Before placing the unit be sure that: 
• the location is in a safe accessible place 
• the framework or the floor or ceiling is adequate to support the weight of the unit, please refer to weight paragraph 
• support points are leveled and aligned 
• the place can not be subject to flooding 
• the maximum level of the snow does not obstruct the airflow to the unit 
 
To ensure the best air circulation to the unit and thus ensure a smooth operation it is recommended to: 
• avoid obstructions to air flow near or above the unit 
• protect the unit from high winds that can favor or not the airflow 
• protect the unit from heat sources or pollutants (chimneys, extractors…) 
• protect the unit from air stratification or recirculation (avoid bad ducting of the fans, containment structure, high walls or 
corners next to the unit) 
These advises if not respected can lead to a lower efficiency of the unit and possible failures. 
 

Checklist 

 
Upon reception of the unit, we suggest that a complete control is carried out, to verify that the unit is intact and complete, 
and  no  damage  has  been  sustained  during  transport.  Any  eventual  damage  revealed  must  be  communicated  to  the 
carrier, demonstrating the reserve clause within the transport documents, specifying the type of damage. 
 

 
Storage 

 
The units must be stored in a dry place, sheltered from the sun, rain, sand and wind. 
Comply with the storage conditions given below: 
• Do not stack the units 
• Maximum temperature = 60°C 
• Minimum temperature = -20°C 
 

The Manufacturer declines any responsibility for any damage as a result of negligence or lack of protection from 
atmospheric agents.
