NOTICE
The following subsections must be read and understood
before attempting to start or operate the unit.
WARNING
The compression process creates noise and operating
screw compressors are loud. Wear the correct hearing
protection when near the compressor during operation.
If people are expected to be in the vicinity of the run-
ning compressor for extended time periods, provide
warnings.
Initial start-up
Prior to the start-up, the prestart check must be
accomplished. See Forms section for Checklist.
Initial start-up procedure
Having performed the prestart check, the compressor unit
is ready for start-up. It is important that an adequate gas
load be available to load test the unit at normal operating
conditions. The following points should be kept in mind
during initial start-up.
1. For proper and safe operation, the compressor must be
run at the proper speed and discharge pressure. Exceeding
design conditions creates a potential hazard.
2. After 1 to 3 hours of operation adjust oil cooling system.
3. Pull and clean suction strainer after 24 hours of opera-
tion. If it is excessively dirty, repeat every 24 hours until
system is clean. Otherwise, follow the normal mainte-
nance schedule.
4. Perform baseline vibration analysis if equipment is
available.

shut down the compressor and correct the problem as
necessary using good safety precautions.
