Chapter 2 – Installation
2.1 Mounting
The compressor must be firmly bolted down to a rigid foundation through all 4 mounting holes to
minimize vibration. Any allowed movement will generally increase vibration which can lead to
component damage.
2.2 Gas Plumbing
Be sure all process lines are free from contamination. Plumbing to the compressor must be sized so
that pressure at the compressor suction is within the range given in Compressor Specifications.
Discharge plumbing must be large enough to pass design flow at lowest expected back pressure
without choking the flow. User’s suction and discharge plumbing should be designed to
accommodate compressor vibration.
If flexible lines are used, user is responsible to secure those lines
to prevent whipping in case of breakage.
Safety relief valves are installed on the compressor at each stage of compression: suction,
interstage, and discharge. Do not start the compressor without these items properly installed. All
plumbing and components must be rated for pressures greater than the connected relief valve
setting.
Provisions must be in place to relieve all internal pressure and isolate the compressor from all
external pressure sources to ensure that the unit can be safely disassembled for maintenance. It
may be helpful to install a hand valve in the gas line downstream of the compressor to create back
pressure for testing and calibration.
Do not install ball valves in either suction or discharge plumbing. If
closed quickly, these valves can cause explosion.
