Description
1. Install the compressor on a level floor suitable for taking its weight. The recommended
minimum distance between the top of the body and the ceiling is 1200 mm (47 in).
2. Remove the plastic plug (if provided) from the compressor air outlet pipe and install an air
outlet valve. Close the valve and connect it to the air net.
3. The maximum total length of the air delivery pipe can be calculated as follows:
For British/American Units:

It is strongly recommended to make the connection of the compressor air outlet pipe on top
of the main air net pipe in order to minimize carry-over of possible condensate residue.
As a rule of thumb, the following formula can be used to calculate the recommended volume
of the air net:
V = (30 x C x p x Q) / dp
