1 Safety Information
Important: Do not operate this equipment until the safety information and
instructions in this user guide have been read and understood by all personnel
concerned. Use of the equipment in a manner not specified within this user guide
may impair the protection provided by the system and could result in an unplanned
release of pressure, which may cause serious personal injury or damage.
Only competent personnel trained, qualified, and approved by Parker Hannifin
should perform service and repair procedures.
When handling, installing or operating this equipment, personnel must employ safe engineering practices and
observe all related local regulations, health & safety procedures, and legal requirements for safety.
Ensure that the equipment is depressurized and the electrical is disconnected from the supply, prior to
carrying out any of the scheduled maintenance instructions specified within this user guide.
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 recognizing that any machinery is
potentially hazardous.
Parker Hannifin 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 Parker Hannifin the user must ensure that the equipment will not be damaged
or become hazardous to persons or property.
The system produces a flow of nitrogen and oxygen gases, which quickly disperses in the atmosphere.
Nitrogen is not a poisonous gas but, in a concentrated form, there is a risk of asphyxiation. Do not directly
inhale the output gas from the outlet pipe.
The system is classified as non-hazardous for transportation purposes and as non-flammable for fire
regulations. Any fire should be fought by means appropriate to the material causing the fire with the
exception being the use of water.
Note: Any interference with the calibration warning labels will invalidate the gas system’s warranty
and may incur costs for the re-calibration of the gas system.
This equipment is for indoor use only. Do not operate outdoors.

2 Description
The Parker Nitrogen Generator is designed to provide a constant supply of nitrogen gas,
at a pre-selected purity, flow, and pressure, as specified in section 2.1 below.
The system uses proven Pressure Swing Adsorption (PSA) technology with a Carbon
Molecular Sieve (CMS) to separate nitrogen (N2) from the atmosphere and store it at a high
purity level.
This user guide contains all of the information necessary for the correct use of the
Parker Nitrogen Generator range. Should you have any questions regarding the safe and
correct installation, operation or maintenance of the generator, contact the supplier
before proceeding.

3 Installation & Commissioning
Do not install this equipment until the following instructions have been read and understood
by all personnel concerned. Minimize the risk of siphoning by installing a check valve between
the system and the source.
Before continuing with the installation and commissioning of this equipment ensure that the
tubing is correctly sized for the pressure and application and that the electrical supply voltage
and frequency meet the requirements detailed within this specification and on the equipment
rating plate.

3.2 Installation of the System
The system should be located indoors on a flat surface, and be protected from direct sunlight, moisture, and
dust (Refer to section 2.1 of this user guide for the system’s environmental specification). When considering
the final location of the system ensure that:
• The system is positioned within easy access of the electrical supply.
• There is adequate space available around the system for ventilation, maintenance access.
• Casters are locked when system is in position.
• The tubing is NSF ¼ in (.63 cm) with 150 psig (10.3 bar) pressure rating.
• Max length of tubing: 300 ft (91.4 m).
• Clearance: Top, bottom, left and right sides: None. Back 6 - 8 inches (15.2 cm - 20.3 cm) to allow
clearance for tubing and power cord, Front: Minimum 12 in (30.5 cm) to allow for ventilation.
Due to the nature of operation, there is a possibility of oxygen enrichment surrounding the
system. 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.
The DN-6 Series is capable of delivering nitrogen at a flow rate of 6 SCFH (2.8 lpm). Nitrogen is
not a poisonous gas but, in a concentrated form, there is a risk of asphyxiation. If the system
is operated within a confined space ensure that adequate ventilation and oxygen monitoring
equipment is fitted.
DO NOT
• Position the system so that it is difficult to operate or disconnect from the electrical supply.
• Position the system directly above electrical equipment as condensate may collect at the base
of the system.
• Use noxious chemicals or machinery that produces fumes within a 20 ft (6 m) radius of the system.
