GENERAL
The maintenance procedures recommended in this section apply to a typical package power plant installation
and do not pertain to any particular plant equipment model.
This section is subdivided into two subsections: the Periodic Inspection Schedule followed by Inspection
and Maintenance Procedures. Although the subjects in each follow the same general order, not every item
listed in the Inspection Schedule is mentioned in the Maintenance Procedures. Only those items which re-
quire special care, or which are not covered by manufacturer's instructions, are covered in the text portion.
Standard maintenance items, such as gauges, switches, valves, filters, etc., have been grouped under one
heading in each subsection. Following this, the items have been grouped by system and major equipment
categories.
In the Periodic Inspection Schedule, the "Inspect" column lists all the systems, components and devices on
the gas turbine and generator that require inspection. In the "What to Inspect For" column, particular points
of each item of inspection are listed as possible defective conditions that should be looked for and corrected.
For temperature and pressure settings, flow rates, calibration data, etc., plus detailed information on the in-
spection and maintenance of any device listed herein, the reader should also refer to the following documents
in this Service Manual:
1. Schematic Piping Diagram
2. Diagram Device Summary
3. Control Specifications
4. Equipment Publications
The "Inspection Frequencies and Turbine Status" column specifies, by means of abbreviations, how often
a device or assembly should be inspected and whether or not the turbine can be operating at the time of inspec-
tion. The left-hand letter(s) designate the frequency and the right specifies the turbine status. Following is
a list of abbreviations used:
Auxiliary and Controls
