NOTE
The design of the foundation is the responsibility of the customer. These comments
are offered as an aid to assure a successful installation, but Ingersoll-Rand Company
cannot assume the responsibility for the design. We recommend that the customer
consult a specialist skilled in the design of machinery foundations.
Leveling
The Centac compressor should be leveled at the time of installation. To level the unit, place it
over the anchor bolts with the feet resting on steel wedges or shims, if necessary (see
Figure 3
).
The unit may be leveled using a machinist level or transit level. When a machinist level is
used, start at one end of the unit and work side to side toward the opposite end, placing the
level on the machined baseplate compressor pads. The compressor should be level from
0 to 0.1 inch/foot (0 to 8 mm/M).
After the unit is level with snug (not tightened) anchor bolts, the coupling should be aligned.
Some baseplate distortion may be noted but this is unimportant as long as the machine pads
remain level. Precise driver alignment is not required until the time of start-up, but should be
within 1/16 inch (1.5 mm). Follow the procedures found in the Operation Manual once the
compressor arrives on site. The General Arrangement drawing lists the values for the
coupling alignment. Record the values obtained, but do not dowel the driver or install the
coupling spacer.

After the coupling has been brought into rough alignment and the alignment values have
been recorded, the Centac compressor is ready for grouting.
