containment station efficiency over time will also depend on proper use and maintenance as per the 

instructions contained in this manual. 

 

All the components, connections and controls used in its construction have been designed and built to a high 

degree of safety to resist abnormal strain or in any case a strain greater than that indicated in the manual. 

Materials are of the finest quality; their introduction and storage in the company and their utilization in the 

workshop are controlled constantly to prevent any damage, deterioration, or malfunction.  

 

DANGER 

Before carrying out any work on the fill containment station each operator must have a perfect 

understanding of how the fill containment station works, know how to use the controls, and 

have read the technical information contained in this manual. 

 

 

It is forbidden to use the fill containment station under conditions or for purposes other than 

those indicated in this manual and Nuvair cannot be held liable for breakdowns, problems or 

accidents caused by failure to observe this rule.  

 

 

Check that the fittings provide a proper seal by wetting them with soapy water: Stop using the 

fill containment station and eliminate any leaks immediately when detected.  

 

 

Do not attempt to repair high pressure tubes by welding them or while the fill containment 

station is pressurized.

 

 

 

Do not empty storage tanks completely—not even for long term storage—as this practice allows 

damp air to get in and eventually corrode the tank.

 

 

 

It is forbidden to tamper with, alter or modify, even partially, the systems and equipment 

described in this instruction manual, especially as safety guards and safety symbols are 

concerned.  

 

 

It is also forbidden to carry out work in any way other than that described or to neglect the 

illustrated safety tasks. 

 

 

 

The safety information and the general information given in this manual are very important. 

 

 

 

2.0  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.  

 

WARNING 

This equipment is used to provide breathing air or nitrox for the purpose of life support. Read 

this manual in its entirety. Failure to heed the warnings and cautions contained in this 

document may result in severe injury or death. 

 

WARNING 

The equipment you will be using to fill air or nitrox cylinders will expose you to 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. 

 

WARNING 

Any pressurized hose can cause extreme harm if it comes loose or separates from its 

connections while under pressure and strikes any part of your body. Use appropriate care in 

making and handling all gas connections.
