Turn off the supply pressure and depress the purge cover to release the air from the second
stage. When the intermediate pressure drops to zero you should see the clear hydrostatic
diaphragm (33) pull into the body assembly. If the regulator is re-pressurized, the clear
diaphragm will push out to the flat position. If (by mistake) the env cap (34) is loosened and then
re-tightened without pressure applied to the first stage, the clear diaphragm will bulge outwards
when the regulator is under pressure.
