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 plug is located at the bottom of the discharge end of the
compressor. (See Figure 5-1, page 38.)
ENCLOSURE
- The compressor, electric motor, water 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 be opened and removed as necessary for service procedures. The enclosure doors are held
by two latches and lift away from the enclosure. The air filter, water filters, and water treatment cartridge
are easily accessible through a side or end door.
DANGER
Do not operate the compressor with the belt guard removed. Exposed belts
may cause injury to personnel.
COMPRESSOR WATER SPECIFICATION
- The compressor unit is supplied with an integral filtration
system (by reverse osmosis) to ensure adequate quality levels for the injection water system. In order to
maintain the water filtration system working at peak efficiency, the incoming water supply must meet a
number of requirements. Please refer to the “RO Water Filter”, Section 8, of this manual for details.
WARNING
Back flow Preventers must be installed on the potable water supply line to the
compressor to prevent high pressure air from blowing into the water supply.
WARNING
Use of compressor initial fill and make-up water not meeting all water
specification standards noted may result in contamination of the discharge air
stream.
