STEP 6
The nitrox percentage can now be read at both
02 analyzers on the compressor panel.
The analyzer labeled “Membrane Output”
analyzes the permeate gas at the membrane
output port (Fig. 70).
The analyzer labeled “HP Outlet” analyzes the
gas after it has passed through the HP compressor
and filtration.
This is the analyzer that indicates the 02% of the
nitrox fill (Fig. 71).
NOTE: Both analyzers should have the same reading or - .5%.
NOTE: Actually two things will happen: as we start supplying nitrox we start to displace the compressors
need for air - we can hear the suction getting quieter at the same time the needle of the nitrox permeate
pressure gauge starts to rise. We continue to add pressure to the system until we get about 1psi of
Nitrox pressure.
You are now pumping nitrox through the compressor, through the purification filter system, out through
the HP Fill Whip. You are venting through the fill whip all nitrox until both analyzers show the chosen
% + or - 0.5% 02. The system should stabilize within 5-8 minutes. If the system doesn’t stabilize within
8 minutes, you should call us for trouble shooting assistance AEROTECNICA COLTRI S.r.l.
