WARNING
There may be oxygen deficiency in the nitrogen gas.
Observe the following instructions when using.
Use in well ventilated locations.
Ventilate the work area when nitrogen gas is being used.
Periodically inspect nitrogen gas piping for leakage.
Oxygen-rich gas is discharged from the exhaust
port of the membrane unit, so be aware of the
following points when installing the equipment.
Install away from fire or flammable objects.
Ventilate the work area during operation of the equipment.
Do not use the product for any purpose directly related to human life.
CAUTION
Do not use reverse air flow.
Do not pressurize suddenly. The differential pressure
gauge or mantle may be damaged. [NSU Series]

The service life of the membrane unit differs
according to the working conditions. As a guideline,
replace the membrane every 3 to 5 years.
Confirm that pressure has been released before mounting
or removing the bowl and bowl guard. [NSUSeries]
Be aware that adequate time is necessary to obtain a required
nitrogen concentration after compressed air is supplied.
Precautions for the inline oxygen monitor
Do not disassemble or modify this product. Doing so
could result in faults.
The sensor may deteriorate depending on the
working conditions. To maintain performance longer,
yearly calibration is recommended.
