3.1
Pre-startup System Inspection
1.
Visually inspect the entire system for obvious damage or leakage. Fix all issues that are
found. If major shipping damage is found contact RIX for repair or replacement parts.
2.
Ensure that any safety guards are securely attached.
3.
Ensure supply pressure is within the range stated in
Compressor Specifications
.
3.2
Start-Up
After performing the pre-startup system inspection, start the unit. When starting the compressor
for the first time or after servicing, check for leaks in the plumbing – see
Section 7.2
for
recommended leak check procedure. After correcting any leaks in the system, restart the unit and
observe gas pressures and temperatures. The pressure will increase based on back pressure from
the User’s downstream plumbing. Gas temperature will also rise in conjunction with the
compression ratio of each stage.
All shutdown devices and control logic should be tested before the system is put into autonomous
operation.
3.3
Normal Operating Conditions
The table below shows theoretical operating conditions—actual pressures and temperatures may
vary. Due to the inclusion of a back-pressure regulator in the compressor package, the discharge
pressure should always be a minimum of 1500 psig. Do not adjust the back-pressure regulator
setpoint as it keeps the 2
nd
stage floating piston from hitting the 2
nd
stage valve during normal
operation.

CAUTION
Cylinder heads and discharge lines are hot. Touching any part of
the cylinder heads or discharge lines can cause burns.
It is recommended that the
Service Log
in the appendix of this manual be used to note operating
pressures, temperatures, and maintenance done at hours of compressor operation. If pressures do
not fall near the above stated values, or vary from your historical pressures, see
Chapter 6 –
Troubleshooting
for corrective action.
