Q-390/MCH 36Electric Nitrox System 13.0 Installing the Q-390/MCH36 Nitrox System If any information in this manual conflicts with any of the other manuals call Nuvair before proceeding. The Nuvair System should never be operated in a facility where the room temperature exceeds F (40 C) while the system is in use. -
Page 20: Electrical Power Connection
Improper wiring may lead to fires, which can cause serious personal injury or death. The electrical power to the Nuvair Nitrox System must be off while wiring this system for service. Failure to ensure that the electrical power is off can lead to severe personal injury and death by electrocution. -
Page 21: Check Compressor Lubricant Levels
Check lubricant levels before starting the LP and HP compressors and add lubricant as LP oil fill & required. Use only the lubricants specified by dip stick Nuvair. Compressor lubricant level sight gauge 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. -

%. The fill oxygen analyzer supplies more accurate oxygen readings, within +/- 1% O . For cylinder nitrox fills, the user must always verify the final fill with a third independent oxygen analyzer. NUVAIR Q-390/MCH36 Nitrox system User Manual Page... - Page 23 The oxygen analyzers may require re-calibration after 10-20 minutes of operation due to humidity and temperature change effects on the sensor. To recalibrate, turn off the LP feed air and follow calibration instructions. NUVAIR Q-390/MCH36 Nitrox system User Manual Page...

Page 24: Producing Nitrox
Never allow any gas stream to be directed at any part of your body. 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. - Page 25 40% oxygen. When filling oxygen clean cylinders, hyper-purification of the nitrox is required using an optional oxygen compatible air purification system available from Nuvair. This nitrox system does not produce nitrox mixtures acceptable for 100% oxygen service.

Page 26: Pumping Nitrox
When the HP compressor auto drain engages and dumps condensate, the fill oxygen analyzer reading will decrease momentarily due to the pressure drop in the system. It will return to its previous reading within seconds after the auto drain sequence stops. NUVAIR Q-390/MCH36 Nitrox system User Manual Page... - Page 27 4) After filling is complete, close the cylinder valve, vent the bleed valve, and remove the cylinder. 5) Test the nitrox O % in the cylinder using an independent oxygen analyzer such as the Nuvair O Quickstick . Calibrate the analyzer before use in accordance with manufacturer’s instructions.
