Hard surfaces may reflect noise with an apparent increase in the decibel level. When sound transmission is important, a sheet of rubber or cork can be installed beneath the machine to reduce noise. Flexible piping may be required. It is recommended that provision be made for lifting heavy components during major overhaul. Use only lifting points provided. Minimum space in front of control panel door as required  by National or Local codes must be maintained. The compressor can be installed on any level floor  capable of supporting it. A dry, well ventilated area where the atmosphere is as clean as possible is recommended. Sufficient space all round and above the compressor must be allowed, to enable the effective removal of the cooling air which, in turn, will reduce the risk of recirculating the cooling air back through the compressor.
