NOTICE
These compressors have aluminum oil coolers; do not use any cleaning
solution that is not compatible with aluminum. Use of improper solution may
result in damage to the cooler.
Water-Cooled Units
- The water-cooled unit with the standard enclosure requires sufficient air flow,
Figure 2-2, for electric motor cooling. Air is drawn into the unit at the top of the enclosure and is
exhausted at the motor side. Do not block air flow to and from unit. Allow three and one-half (3-1/2) feet
(1.1 m) to the nearest obstruction on the starter end and control box side of the unit. Allow three (3) feet
(.9 m) to the nearest obstruction above and on other sides of the unit.
FOUNDATION
- The Gardner Denver Rotary Screw compressor requires no special foundation, but
should be mounted on a smooth, solid surface. Whenever possible install the unit near level. 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, or danger of shifting from outside vibration or moving vehicles may require the use of mounting bolts
and shims to provide uniform support for the base.
OIL RESERVOIR DRAIN
- The oil drain is piped from the bottom of the reservoir to the side of the frame.
This drain is approximately 4.50 inches (115 mm) above the floor level. If this is not sufficient to
conveniently drain the oil some other methods of providing drain 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.
If the compressor unit base is raised above floor level, the space between the
floor and the base bottom must be closed with solid material all around to
prevent recirculation of hot air from the oil cooler end and over temperature
operation.
ENCLOSURE
- The compressor, electric motor, oil cooler and aftercooler 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. Any of the enclosure doors may be removed by opening the
door and lifting it up slightly to disengage the hinges.
The motor inspection/air filter service panel is held by two latches and lifts away from the enclosure. The
air outlet panel is attached by screws to the enclosure and is not readily removable.
