CR 
Install the compressor horizontally, in a cool but frost-free and well-ventilated room. Place the compressor as 
level as possible; however, CR can be operated with a maximum inclination of 40% (22.5 degrees) in any 
direction. The air should be clean. 
It is recommended to install an automatic condensate drain (available as an option) on the air receiver to 
ensure continuous condensate removal. 
CR Contractor 
The compressors are equipped with a lifting eye or yoke. When running, the compressor must be installed as 
level as possible; however, it can be operated temporarily in an inclined plane of maximum 25% (or 20 
degrees). Keep the compressor in a frost-free and well-ventilated place.
