WARNING
For copper water coolers, do not use any cleaning solution that is not
compatible with copper. Use of improper solution may result in damage to the
cooler.
Water-Cooled Units -
Shell and tube water and aftercooling cores are supplied as standard equipment
on all water-cooled units. A small air-cooled motor and fan are used to ventilate the enclosed package.
See “Air Cooled Units” for location recommendations.
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 frame (See
Package Illustrations on pages 2 and 3, for details). The drain connection is about 4 inches (100 mm)
above the floor level. If this impedes oil drainage, consider the following options:
•
Elevate the package of blocks to obtain the desired drain height.
•
Provide an oil sump/trough below the floor level and pump or bail the drained oil.
•
Evacuate the oil charge with vacuum.
CAUTION
If the package is raised above floor level, the voids between the base frame and
the floor may increase the package noise level and/or affect air-cooled core
performance. Said voids must be blocked with solid, sound absorbing
materials.
Oil Breather
- Potential contamination of the compressed air stream with gear box oil vapors, vented
through the breather, may be avoided by piping said vapors away from the package confines.
CAUTION
When remote mounting the oil breather, avoid low spots on the piping where oil
could collect and affect vapors venting.
ENCLOSURE
- The compressor, electric motor, water cooler and aftercooler are mounted inside the
enclosure.
