PREPARING FOR COMMISSIONING

5.1

Piping

Remove all blank flanges, stoppers, caps, and desiccant bags before installing the piping.
Distributor piping and pipe connections must be the correct size and designed for the operating temperatures
and pressures.
Label the compressed air and water lines according to local requirements.
Support all piping appropriately. Pipes must not bear any loads.
If compressed air hoses are used, they must be of the correct size and must be suitable for the operating
pressure and temperature. Do not use worn, damaged, or substandard hoses.
A shutoff valve should be installed in the supply line, so that the compressor can be isolated for maintenance
purposes.
The drain line running away from the condensate connection must be pitched at no greater than 5 / 16.4 ft. m.
An air tank of sufficient volume should be installed (as a buffer) between the compressor and the compressed
air network. As a guideline for the tank capacity, select a size that is 10% of the supply volume. For example, a
compressor with a supply volume of
10m³/min
/ 353 ft³/min requires a tank with a volume of
13-25-640 v00 Page 30
1 m³ /
35 ft³.
