Notes:
For couplings, check bolts, shim packs, center inserts, keys, and all bolt torques.
For suction and discharge ange bolts, verify the tightness of the bolts. See Table 9 for torque requirements.
For variable frequency drive (VFD) units, check for excess vibration and skip frequencies any time unit operating conditions change.
For electrical connections, check and torque all terminals in the processor and starter panel in accordance with the specication posted in
the enclosure.
For linear transmitters, see Calibrating the linear transmitter.
For sensor calibration, check pressures and temperatures using a NIST certied device.
For vibration analysis, baseline vibration analysis is required during initial commissioning. Vibration measurement must be carried out con-
tinuously to obtain optimum preventive control on bearings. If not continuously controlled, then every 6 months, more frequently if levels
increase. See additional notes in Maintenance program.
When replacing oil lters, you may need to change the lter more frequently based on differential pressure or as directed by oil analysis.
For checking alignment, refer to 070.210-IB, Screw Compressor Foundations for foot-mounting alignment.
