5.0 MAINTENANCE
5.1 Overview
This chapter provides the user with maintenance information and instructions on
how to remove and install NGC components. Performance of the recommended
procedures maintains the unit in optimum operating condition, reduces system
downtime and ensures accuracy of natural gas sample analysis.
It is recommended that the user develop regularly scheduled daily, weekly or
monthly maintenance programs. By establishing such programs, NGC downtime
will be reduced and the system will operate at optimum analytical efficiency.
Perform all the recommended procedures as presented within this chapter.
Practical experience permits updating the maintenance procedures and
associated schedules over time. This results in many procedures being performed
on a routine basis before potential problem(s) result in a failure.
Do not open or remove covers, including the PCCU local
communications cover, unless the area is known to be non-
hazardous, including the internal volume of the enclosure.

Help
If technical assistance is required during performance of maintenance functions or
if returning parts, contact ABB Totalflow customer service department at the
following phone number:
USA: (800) 442-3097 or International: 1-918-338-4880
5.1.2
Maintaining Cleanliness
It is important that an inspection time period be established to examine the unit for
internal and external cleanliness and damage.
Because an NGC installation is primarily exposed to external environmental
conditions, it is important that it be regularly inspected for cleanliness, both
externally and internally. Even though the NGC is tightly sealed against moisture
and foreign contamination, it is recommended that the internal components be
examined for moisture and/or contamination. If contamination is found, the system
should be shut down and cleaned. If such contamination is not removed, it could
render the NGC inoperable.
5.1.3
How to Use This Chapter
It is recommended that the user develop a regularly scheduled maintenance
program. By establishing a maintenance program, NGC downtime can be
minimized.
Record all items within this chapter in the maintenance practice procedures.
Practical experience permits updating this schedule over a period of time. This
results in many maintenance items being handled on a routine basis before
potential problem(s) result in a failure.
5.1.4
Returning Part(s) for Repair
If a Totalflow component is to be returned for repair, securely wrap it in protective
anti-static packaging. Before returning a component, call for a return authorization
number (RA). Affix this number to the outside of the return package.
