Emergency shutdown procedures
a.
In an emergency, push appropriate red button to shutdown either a selected system or all operating systems.
b.
When emergency situation has been corrected, reset emergency button by turning collar behind button one-
quarter turn clockwise Button will pop out and again be in ready position.
c.
After emergency button is reset, restart compressed air system according to procedures in Section II and Section
III.
Section IV. Operation under extreme conditions
3-10
General. Operation of this system in extreme temperatures and high humidity requires special maintenance
procedures. These conditions are discussed below.
3-10.1 Operating in extreme heat. Operating compressor in continued high temperature (average daily temperatures in
ROWPU space exceeding 90 degrees F) tends to break down oil protection. Under these conditions on Barge 1, shorten
oil change intervals from semiannually to quarterly and 1000 hours to 500 hours On Barges 2 and 3, shorten oil change
interval from every other month to monthly.
3-10.2 Operating in high humidity. Operating in high humidity, often combined with high temperatures, creates large
amounts of moisture in receiver, valves, filters, and pipes. If not eliminated, this moisture creates corrosion that leads to
clogged pipes and leaks. To prevent this, when humidity is high, entire system should be shutdown every 12 hours of
operation and completely drained. This requires opening receiver drain cock, opening air filter drains, and opening all air
station valves.
3-10.3 Operating in extreme cold. This system is in ROWPU space, which has several heat-generating items and
requires continued above freezing temperatures for processing water. Therefore, its operation in extreme cold is most
unlikely.
