Fill Oxygen Analyzer Showing the proper reading for intended fill
Nitrox Storage Pressure DO NOT exceed rating of tank or 3600 P.S.I (250 bar)
4) After filling is complete, close cylinder valve, vent the bleed
valve, and remove the cylinder.
5) Test the Nitrox %O
2
in the cylinder using an independent Oxygen
Analyzer such as the Nuvair O
2
Quickstick. Calibrate analyzer before
use in accordance with manufacturer’s instructions.
6) Repeat steps 1-5 until you have filled all scuba cylinders.
7) Mark each tank with fill date, %O
2
, fill pressure, and MOD
(Maximum Operating Depth).
8) Log every Nitrox fill to document the following information:
♦
Fill date and time of day
♦
Tank Number
♦
Supplier’s check of oxygen content (%O
2
) plus signature and date
♦
User’s check of oxygen content (%O
2
) plus signature and date
♦
Fill Pressure
♦
MOD (Maximum Operating Depth) in user’s handwriting
♦
Nitrox certifying agency and card number
9) When filling a HP Nitrox storage tank, verify that Fill Oxygen Analyzer %O
2
reading equals the
desired Nitrox %O
2
. Open applicable line valves and tank valve, and fill with Nitrox. Do not exceed
rated pressure of cylinder, and do not exceed 3600 psi (250 bar) under any condition. After filling
is complete, close all valves and allow Nitrox System to shut down.
15.4 Pumping Air
To use the System to pump air, simply turn off the LP Compressor. No Nitrox will be supplied to the
HP Compressor, and it will pump air only. When the HP Compressor is pumping air, the Permeate
Oxygen Analyzer and the Fill Oxygen Analyzer should both read 20.9% O
2
.
Always use Oxygen Analyzers to monitor oxygen content of any gas flowing through the
System. Both air and Nitrox are subject to variations in oxygen content.
Use Independent Oxygen
Analyzer for Verification
