Pneumatic components (nitrogen gas extraction unit)
Safety Precautions
Be sure to read this section before use. Refer to [Pneumatic, Vacuum and Auxiliary
Components (No. CB-024SA)] for general pneumatic components precautions. Although the
above general catalog states that products are not applicable for equipment or applications
with direct contact with beverages/foodstuffs, the FP2 Series products can be used in such
applications as long as they are within the range of the product specifications.
Product-specific cautions: Nitrogen gas extraction unit NS, NSU, PNASeries
CAUTION
Working environment
Avoid installing this product where it will be subject to direct
sunlight or rain.
As the bowl material is polycarbonate, avoid use with the following chemicals
or in an atmosphere containing these chemicals. [NSU Series]
Avoid use in environments where ozone is generated.
Avoid use where vibration and impact are present.
Avoid using this product where it will be subject to air with
a relative humidity of 50% or more. (Performance will
decrease sharply if the separation membrane gets wet
with droplets. (such as water))
Avoid using air containing corrosive gases (strong acidic
gases such as hydrogen sulfide, sulfur dioxide, hydrogen
chloride, fluorine, etc.) or strong alkali gases (amines,
ammonia, caustic soda, etc.).
The needle valve cannot be used as a stop valve
that requires no leakage.
Slight leakage is allowed for in this product's specifications.
Dust cannot be completely kept out of the flow path.
Install a final clean filter if dust could be a problem with the circuit.
(Use anti-bacterial/bacteria-removing filters for food processes.)
"Compatible with Food Sanitation Act" indicates that the
product material compliants to the Food Sanitation Act.
Use after confirming the structure and material, valve
structure, working fluids, and working atmospheres
of each component carefully for yourself.
Internal parts may wear when the needle valve operates.
If the product is affected, take necessary measures, such
as installing a filter on the secondary side.
Check the working circuit and working fluid.
To prevent drop in membrane unit performance, install
the dryer, air filter and oil mist filter on the primary side,
and remove water or oil. If the working fluid could contain
hydrocarbons, install an activated carbon filter.

Precautions for the inline oxygen monitor
Working environment
Avoid installing this product where it will be subject to direct sunlight or rain.
Using the oxygen sensor in the following atmospheres may cause measurement
errors and lower performance of the Component and oxygen detector.
Use outside the 0 to 50°C temperature range or with
elements other than air causes significant measurement
errors. Avoid using in such conditions.
The device cannot be used in air containing freon gas,
silicon gases, corrosive gases such as SOx (sulfur oxides)
or H2S (hydrogen sulfide), or halogen gases such as Cl2
(chlorine), F2 (fluorine), or Br2 (bromine), or in air
containing constituents which cause these gases to
separate at high temperatures of approximately 500°C.
Use with air that contains combustible gas causes the gas to burn, lowering indications.
Use in air containing large amounts of dust or oil mist
leads to element deterioration.
Coming into contact with water drops, solutions, or other liquids leads to element damage.
The element will be damaged if used in locations with strong impacts or vibrations.
Avoid use in locations with strong magnetic fields or significant electrical noise.
Indications are not stabilized in environments in which
pressure pulses (continuously changes) on a short cycle.
Static pressure is required for stable measurements.
Check the working circuit and working fluid.
To prevent decreased oxygen concentration monitor
performance, install the dryer, air filter and oil mist filter on
the primary side, and remove water or oil.
Air dryer Filter
This product does not have explosion-proof specifications.
Since the detection element is heated by the heater, it may
lead to an explosion if used in an explosive atmosphere.
This product is not an oxygen detector. Do not use it
as an oxygen concentration monitor in accordance
with the Industrial Safety and Health Act.
When using this product as a CE compliant product, prepare a dedicated power supply.
