1 Safety Information

Do not operate this equipment until the safety information and instructions in this user guide have been read and understood by all 
personnel concerned.

The pressure envelope of the generator must not be breached under any circumstances. Failure to comply may result in an unplanned release 
of pressure, and may cause serious personal injury or death. All maintenance procedures that require the pressure envelope to breached must 
only be performed by competent personnel trained, qualified, and approved by Compair. 

Due to the nature of operation there is a possibility of oxygen enrichment surrounding the generator. Ensure that the area is adequately 
ventilated. Where the risk of oxygen enrichment is high, such as a confined space or poorly ventilated room, the use of oxygen monitoring 
equipment is advisable.

Nitrogen is not a poisonous gas but, in a concentrated form, there is a risk of asphyxiation. Depending upon the model and operating pressure, 
the generator is capable of delivering nitrogen at a flow rate of 33.3 m

3

/hr. If the generator is operated within a confined space ensure that 

adequate ventilation and oxygen monitoring equipment is fitted.

Use of the equipment in a manner not specified within this user guide may result in an unplanned release of pressure, which may cause serious 
personal injury or damage.

When handling, installing or operating this equipment, personnel must employ safe engineering practices and observe all related regulations, 
health & safety procedures, and legal requirements for safety.

Ensure that the equipment is depressurised and electrically isolated, prior to carrying out any of the scheduled maintenance instructions 
specified within this user guide.

Only competent personnel trained, qualified, and approved by Compair should perform installation, commissioning, service and repair 
procedures.

Note: Any interference with the calibration warning labels will invalidate the gas generator’s warranty and may incur costs for the re-calibration 
of the gas generator.

Compair can not anticipate every possible circumstance which may represent a potential hazard. The warnings in this manual cover the most 
known potential hazards, but by definition can not be all-inclusive. If the user employs an operating procedure, item of equipment or a method of 
working which is not specifically recommended by Compair the user must ensure that the equipment will not be damaged or become hazardous 
to persons or property.

Most accidents that occur during the operation and maintenance of machinery are the result of failure to observe basic safety rules and 
procedures. Accidents can be avoided by recognising that any machinery is potentially hazardous.
