2.1 MOUNTING OF COMPRESSOR PACKAGE
The compressor package should be placed over a
surface or foundation that is capable of supporting
its weight, while remaining level and free of deflec-
tions which may affect the driveline mounts or the in-
board pipework.
It is recommended that the package frame be lev-
eled and secured to the foundation with adequate
anchorage, and that a good grade grouting be used
to insure full contact between the load bearing sur-
faces.
The compressor/motor driveline is self--aligned by
the use of a rigid distance piece and supported by
flexible vibration isolation mounts. Poor leveling or
excessive deflections may adversely affect the op-
eration and longevity of these devices.
No piping loads should be transmitted to the air and
water connections provided with the package.
2.2 VENTILATION AND COOLING
For air--cooled compressors, select a location to
permit a sufficient unobstructed flow of air through
the compressor to keep the operating temperature
stable. The minimum distance that the compressor
should be from surrounding walls is three (3) feet
(91.4 cm). To prevent excessive ambient tempera-
ture rise, it is imperative to provide adequate ventila-
tion.
For water--cooled compressors, it is necessary to
check the cooling water supply. The water system
must be capable of supplying the flow requirements
listedinTable1.

Table 2 indic at es t he v ent ilat ion r equir em ent s nec -
essary to keep the compressor running at a normal
operating temperature. The fan air requirement is
the volume of air which must flow through the com-
pressor for proper ventilation. The specified heat re-
jection requirement is the amount of heat that is ra-
diated by the compressor. This heat must be re-
moved to assure a normal operating temperature.
With air--cooled compressors it is possible to use
this heat for space heating, providing no additional
pressure drop is created across the fan. Consult a
Sullair representative for assistance in utilizing this
heat.
DO NOT
install a water--cooled or an air--cooled/af-
tercooled compressor where it will be exposed to

2.3 SERVICE AIR PIPING
Service air piping should be installed as shown in
F igur e 2 -- 1. A s hut -- off v alv e s hould be ins t alled t o
isolate the compressor from the service line if re-
quired. Also notice that the service line should be
equipped with water legs and condensate drains
throughout the system.

“The Plastic Pipe Institute recommends against the
use of thermoplastic pipe to transport compressed
air or other compressed gases in exposed above
ground locations, e.g. in exposed plant piping.” (I)
Sullube 32 should not be used with PVC piping sys-
tems. It may affect the bond at cemented joints. Cer-
tain other plastic materials may also be affected.
(I) Plastic Pipe Institute, Recommendation B,
Adopted January 19, 1972.
2.4 SHAFT COUPLING CHECK
The compressor unit and motor are rigidly con-
nected via a cast adaptor piece which maintains the
shaft coupling in proper alignment. It is recom-
mended that prior to initial startup, all coupling fas-
teners are checked for proper tensioning. Refer to
the Coupling Service Procedures included in the
Maintenance section of this manual.
2.5 FLUID LEVEL CHECK
The air compressor is also supplied with the proper
amount of fluid. However, it is necessary to check
the fluid level at installation. The level is checked by
looking at the sight glass located near the sump. If
the sump is properly filled, the fluid level should be
visible in the sight glass.
