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 - A combination oil/air cooler is supplied as standard equipment on all air-cooled
packages. The heat exchangers require sufficient cooling air flow to operate efficiently – please refer to
Section 6, Fig 6-1 of this manual for detailed instructions on the operation and maintenance of air-cooled
heat exchangers, including minimum heat exchanger cooling and enclosure ventilation requirements.
Air for heat exchanger cooling is drawn in at the cooler end of the enclosure and is exhausted through a
roof vent. Air for motor cooling, electronics cooling, and for the compressor intake is drawn in at the
controller end and exhausted through three (3) roof vents. Refer to Package Illustrations on Figure 1-2
and Figure 1-3, pages 10 and 11, for hardware details.
Do not block flow of air entering or exiting the enclosure - allow 3-1/2 feet (1.1 m) clearance to the nearest
obstruction all around and on top.
