Installation Guidelines

2.1.1 Required 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.

2.1.2 General 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 5 to 10-
micron inlet filter to remove debris from the gas stream. The degree of filtration required depends on
the specific application.

Inlet and Discharge Pressures

Refer to Table 1 for acceptable inlet and discharge pressure levels.

Level
0.75 psig Consult the factory for operations below 0.75 psig.
Operation at pressures above 25 psig will result in:
25 psig • Excessive oil carryover
• Loss of oil from the Compressor Module
When the discharge pressure of the Compressor Module reaches the maximum,
which ranges from 70 to 190 psig, depending on the model (see Compressor
Module Nomenclature on page iv):
70 psig

All Compressor Modules must be equipped with pressure-limiting or relief
devices. A minimum pressure differential of 70 psi between inlet and discharge
pressure is required for proper operation.
