c.
Reposition unit accordingly as the wind changes direction.
d.
Be certain that no exhaust from running vehicles are in the vicinity of the unit.
e. Check ambient air for carbon monoxide and carbon dioxide contamination with the Detector Set. Compare
the results with Table 1-1. Change the operation site if these levels are excessive.
The location of the compressor intake with respect to possible sources
of contamination is fully as important as any single factor in assuring
satisfactory air quality. The compressor unit should not be operated
near exhausts of internal combustion engines, sewer manholes,
sandblasting, painting, electric arcs, or sources of smoke.
f.
The compressor unit, since it is diesel powered, must be located outdoors, never indoors.
g.
Place compressor unit on level surface. Refer to Table 1-2 for maximum permissible inclination.

SHORT TERM STORAGE. Short term storage of the compressor unit, storage of about 6 months or less, may be
accomplished by performing the following steps.
WARNING
All work performed on the compressor unit must be accomplished only
while the unit is depressurized.
a. Run the compressor unit at operating pressure (open drain valve 13, Fig. D-2) to maintain 3000 PSI on final
pressure gauge (19, Fig. D-2) and temperature for approximately 10 minutes. All other valves should be closed.
