Air for motor cooling and for 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 and Figure 1-3, pages 9 and 10, for hardware
details.
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, 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 – Sump drain port is located on the lower, right hand corner of the controller-
side of the base-frame
– see Package Illustrations for further details. 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.
INSTALLATION FOR COLD WEATHER OPERATION
It is recommended that the unit be installed
inside a shelter that will be heated to temperatures above freezing (40
°
F, 5
°
C). This will eliminate many
of the problems associated with operating units in cold climates where freezing rain, drifting snow,
freezing condensate and bitter cold temperatures are encountered.
Do not operate the compressors with the fan or coupling guard removed.
Exposed fan and couplings may cause personal injury.
