Page 4: Introduction
Titan Nitrox System Introduction This manual will assist you in the proper set-up, operation and maintenance of the Nuvair Titan Nitrox System. Be sure to read the entire manual. Throughout this manual we will use certain words to call your attention to conditions, practices or techniques that may directly affect your safety. -
Page 5: Safety Warnings
Titan Nitrox System Safety Warnings Nuvair has taken extreme care in providing you with the information you will need to operate this system. However, it is up to you to carefully read this manual and make the appropriate decisions about system safety. - Page 6 Titan Nitrox System Do not use this system to produce Nitrox mixtures containing more than 40% oxygen. Pumping Nitrox mixtures with higher concentrations of oxygen may lead to fires or explosions, which can cause serious personal injury or death. The use of enriched air Nitrox does not eliminate the risk of decompression sickness (DCS) in diving.

Titan Nitrox System 13.0 Installing the Nitrox System If any information in this manual conflicts with any of the other manuals call Nuvair before proceeding. Ambient room temperature should never exceed 100 F (38 C) during operation of the Nitrox System. -
Page 18: Electrical Power Connection
Titan Nitrox System 13.3 Electrical Power Connection Never use extension cords to provide power to your Nitrox System. The system must be properly wired according to national and local electrical codes by a qualified electrician. Improper wiring may lead to fires, which can cause serious personal injury or death. -
Page 19: Pre-Operation Instructions
Titan Nitrox System 14.0 Pre-Operation Instructions Do not allow Nitrox to be discharged into the air storage system. Nitrox introduced into the air storage system could cause a diver to suffer from oxygen poisoning at depth. Oxygen poisoning is extremely dangerous and can lead to drowning. -
Page 20: Oxygen Analyzer Calibration
Titan Nitrox System Oxygen Analyzer Calibration Gas production may be monitored with the Permeate Oxygen Analyzer before entering the HP Compressor to obtain a rough estimate of %O (+/- 2%); however, do not rely on this reading as an indication of %O at the HP Compressor outlet. - Page 21 Titan Nitrox System Calibrate Oxygen Analyzers as follows: 1) Turn off the LP Feed Air by rotating the feed air supply valve slowly up to the closed.

Titan Nitrox System Fill Oxygen Analyzer - Alternate Calibration Method Fill Oxygen Analyzer The Fill Oxygen Analyzer can also be calibrated in ambient air as an alternative. This is especially useful during routine re-calibration while the system is operating. Different settings may be used depending on location, so verify your actual ambient conditions and refer to the Oxygen Analyzer manual for details. -
Page 23: Producing Nitrox
Titan Nitrox System 15.0 Producing Nitrox The equipment you will be using to manufacture Nitrox (oxygen rich air) will expose you to both low and high-pressure gas. Gas, even under moderate pressures, can cause extreme bodily harm. Never allow any gas stream to be directed at any part of your body. -
Page 24: Setting Proper Pressure
The Heater Thermostat Control green indicator light will stay on until operating temperature is reached. Do not change the temperature setting on the Thermostat Control without contacting Nuvair. Changes in temperature settings may cause Membrane damage. A damaged membrane will not produce the correct Nitrox mixture which can lead to severe personal injury if the gas is used for diving purposes without proper analysis. -

2) HP Compressor Lubricant: Change Compressor Lubricant every 100 hours or annually, whichever comes first. Only use lubricants rated for use with Nitrox, such as Nuvair 455 Never mix Compressor Lubricants. See Section 17.4 and HP Compressor manual for details. - Page 30 Titan Nitrox System 3) LP Air Filtration Inspection: On a weekly basis, inspect each Filter Bowl for the presence of moisture and each Element for any unusual degradation or wetness. See Section 17.5 for details. 4) LP Air Filtration Elements: Change LP Filter Elements every 200 hours. When a dryer (see page 33) is used with the system or hot and humid environment exists this number can vary to maintain CGA Grade D air standards.
