STEP 7
Slowly adjust, no more than a fraction turn, the
nitrogen valve until the chosen percentage of nitrox
is achieved.
Clockwise decreases 02 reading; counter
clockwise increases 02 reading.
Wait approximately 1 minute before any additional
adjustment is made (Fig. 72).
Keep in mind the permeate pressure gauge needs
to remain at approximately 0,07 - 0,1 bar
(1-1.5 psi) and a slight adjustment with the LP
regulator may be needed. (See Step 5) (Fig. 73).
For example, if the psi is lower than 1, adjust the
regulator up slightly. If the psi is higher than 1.5,
lower the regulator slightly.
STEP 8
When the proper concentration of nitrox is achieved and the permeate pressure gauge reads 1psi, the
HP Fill Whip can now be closed and the dive tanks or storage cylinders can now be filled according to
the manufacturer recommendation.
Monitor compressor operation. The Auto Condensate Drains will activate every 10-15 minutes. (Remember
to manually drain bleed valves once a day. See Page 17)
AUTO DRAIN FEATURE
Operational Note: Drop in low pressure analyzer percentage reading!
When the compressor’s auto drain engages and dumps condensate, the O
2
analyzer reading will go
down due to pressure decrease in the system. It will return to the previous reading within seconds after
the auto drain sequence stops.
