Section II. GAS PUMPING UNIT OPERATION
This section contains the information you will need to operate the GPU when refilling the
trainer coolant supply. Before operating the GPU be sure you have performed all of
the Before (B) operation maintenance checks in table 3-1. If equipment failure occurs
during normal operation, refer to the troubleshooting procedures contained in Section V,
Chapter 3.
2.2 PREPARATION FOR USE
Operation of the GPU must be performed in a large, well ventilated area.
Argon is a colorless, odorless, inert gas which displaces air and in high
concentrations can cause dizziness and suffocation. If you become light
headed while operating this equipment, evacuate work area. High gas
pressure (up to 6200 psig) is used to refill the gas bottle in the trainer. Death
or severe injury may result if you fail to observe safety precautions.
NOTE
Argon gas is still usable even though more than 5 years have elapsed since
the last hydrostatic inspection date stamped on the cylinder.
