LOCATION
- The compressor package shall be installed, whenever possible, in a clean, well-lighted,
well-ventilated area with ample space all around for maintenance. Select a location that provides a cool,
clean, dry source of air. In some cases it may be necessary to install duct work to reach a source of
adequate cooling air, or to direct cooling air in and out of the compressor package to prevent re-
circulation (e.g., not cooling the air entering the fresh air inlet). The package is designed to operate at
ambient temperatures ranging from 40
°
F to 113
°
F (at up to 1000 meter elevation). Contact your local
distributor for package operation at conditions exceeding the stipulated values.
A typical ventilation arrangement is shown in Figure 2-1.

When selecting the compressor package location, be aware that its noise level may increase above its
advertised free-field condition by reflections from nearby objects (e.g., walls, machinery, etc.) or by noise
from nearby machinery.
Air-Cooled Units
– An air-cooling module, separate from the compressor package, is supplied on air-
cooled packages. The module is comprised of individual radiator-type coolers for air and oil services, a
radial cooling fan driven by an inverter-duty, TEFC electric motor, a pulse-width modulated variable
frequency drive to energyze the fan motor and fabricated steel base and fan housing assemblies. The
heat exchangers require sufficient cooling air flow to operate efficiently
– please refer to Section 6 of this
manual for detailed instructions on the operation and maintenance of the heat exchangers, including
minimum heat exchanger cooling and enclosure ventilation requirements.
All interconnecting piping and wiring between the compressor package and the
air-cooled module must be site-installed prior to any compressor operation.
