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.

Warning
The electrical connection must be carried out by an electrician and must correspond to the
local codes. The indications on the motor data plate must correspond to the power supply
voltage and frequency. The installation must include an isolating switch in the power line
near the unit and be protected against short-circuits by fuses for each phase. Refer to
Fuses and wire sizes.
The power supply and grounding lines must be of suitable size. Refer to Fuses and wire
sizes in Section 3.3.
For Automatic Start/Stop, connect the power supply cables as shown in the electrical
