2.1Installation Guidelines
2.1.1Required Component—Inlet Gas Scrubber
An appropriate inlet gas scrubber is REQUIRED to remove liquids from the gas prior to compression. If there is potential for liquid slugging, a suitable trap must be installed to prevent liquid from flooding and damaging the Compressor.
NOTE
Failing to use an appropriate inlet gas scrubber to remove liquids from the gas prior to compression can cause flooding and damage the Compressor.
2.1.2General Installation Guidelines
Follow these general guidelines for installation:
•The Compressor Module must be installed and operated in compliance with all applicable codes and regulations.
•The system must be installed on a level surface.
•Install pipe unions or flanges to connect the system to the inlet and discharge piping for ease of service.
•Install isolation valves on the inlet and discharge piping.
•A common ground must be connected between the Compressor Module and the
Compressor Package chassis. This ground must comply with the National Electric Code (NEC) and any other applicable codes.
•Solid debris also must be removed from the gas prior to compression. When required, use a
