Escaping gas is hazardous. Do not feel for leaks with your hands. Frostbite
or lacerations can result.
NOTE
The pump automatically shuts off when OUTLET PRESSURE gage reads
6000 ± 200 psig. However if the temperature where GPU is located is 60°F or
less, manually stop the pump at 5200 psig. The GPU should not be left
unattended during charging process. If at any time during the charging
process gas is heard escaping, turn off GPU (press OFF pushbutton) and
close argon gas supply valve.
(8) Determine the temperature where the GPU is located and look at the
OUTLET PRESSURE gage (25). At 60°F or below, press the OFF pushbutton (27) when
you read 5200 psig on the OUTLET PRESSURE gage (25). At 60°F or above, wait until
the pump shuts itself off or 6200 psig is reached; in which case, press OFF pushbutton
(27).
(9) Close the OUTLET SHUTOFF valve (29) fully clockwise and slowly open
the OUTLET BLEED valve (28) to remove high pressure from that portion of the line to
the trainer.
