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, Figure 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.
Cooling air for the heat exchangers and the main motor is drawn in at the intake grill end of the enclosure and is
exhausted through a roof vent. Refer to Package Illustrations on Figure 1-2 thru Figure 1-4, pages 9 thru 12, for
hardware details.
Air for the electrical enclosure and the compressor intake is drawn in at the intake grill end of the enclosure and
exhausted via a smaller roof vent – refer to Section 6 of this manual for enclosure ventilation requirements. Refer
to Package Illustrations on Figure 1-2 thru Figure 1-4, pages 9 thru 12.
Do not block flow of air entering or exiting the enclosure - allow minimum of 3-1/2 feet (1.1 m) clearance to the
nearest obstruction all around and on top.
FOUNDATION - The Gardner Denver Rotary Screw compressor requires no special foundation, but should be
mounted on a smooth, solid surface and as near level as possible. Temporary installation may be made at a
maximum 10
°
angle lengthwise or 10
°
sidewise.
Mounting bolts are not normally required. However, installation conditions such as piping rigidity, angle of tilt,
danger of shifting from outside vibration or moving vehicles, or the mounting of the compressor package on its
optional 80 gallon tank may require the use of mounting bolts and shims to provide uniform support for the base.
OIL RESERVOIR DRAIN – Sump drain port, located near the oil filter, is 7-1/2” above the floor level. If this is not
sufficient to conveniently drain the oil, other methods are:
1. Elevate the compressor unit on a suitable structure to obtain the desired drain height.
2. Construct an oil sump or trough below the floor level and pump or bail the drained oil.
3. Pump oil from the reservoir filler opening or drain to a container.
ENCLOSURE - The compressors, electric motors and oil/air cooler assembly are mounted inside the enclosure.
Service doors are provided for maintenance access. Be sure to allow enough space around the unit for the doors
to open completely.
To remove the enclosure doors, open the door and lift it up slightly to disengage the hinges.
Ducting may be required on air-cooled enclosed machines.
Do not operate the compressors with the fan or coupling guard removed.
Exposed fan and couplings may cause personal injury.
