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.
WARNING - USER RESPONSIBILITY
FAILURE OR IMPROPER SELECTION OR IMPROPER USE OF THE PRODUCTS DESCRIBED HEREIN OR RELATED ITEMS CAN CAUSE
DEATH, PERSONAL INJURY AND PROPERTY DAMAGE.
This document and other information from Parker-Hannifin Corporation, its subsidiaries and authorized distributors provide product or system
options for further investigation by users having technical expertise.
The user, through its own analysis and testing, is solely responsible for making the final selection of the system and components and assuring
that all performance, endurance, maintenance, safety and warning requirements of the application are met. The user must analyze all aspects of
the application, follow applicable industry standards, and follow the information concerning the product in the current product catalog and in any
other materials provided from Parker or its subsidiaries or authorized distributors.
To the extent that Parker or its subsidiaries or authorized distributors provide component or system options based upon data or specifications
provided by the user, the user is responsible for determining that such data and specifications are suitable and sufficient for all applications and
reasonably foreseeable uses of the components or systems.
Only competent personnel trained, qualified, and approved by Parker domnick hunter should perform installation, commissioning, service and
repair procedures.
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.
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.
Parker domnick hunter 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 domnick hunter 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.

2 Description
The MAXIGAS range of nitrogen generators operates on the Pressure Swing Adsorption (PSA) principle to produce a continuous stream of
nitrogen gas from clean dry compressed air.
Pairs of dual chamber extruded aluminium columns, filled with Carbon Molecular Sieve (CMS), are joined via an upper and lower manifold to
produce a two bed system. Compressed air enters the bottom of the ‘online’ bed and flows up through the CMS. Oxygen and other trace gases
are preferentially adsorbed by the CMS, allowing nitrogen to pass through.
After a pre-set time the control system automatically switches the bed to regenerative mode. All of the contaminants are vented from the CMS
and a small portion of the outlet nitrogen gas is expanded into the bed to accelerate the regeneration. At the same instant the second bed
comes on-line and takes over the separation process.
The lower purity (%) generators use an equalisation phase designed to reduce energy consumption and enhance the overall performance of the
generator. Immediately after the adsorption phase the inlet, outlet and exhaust valves close on both beds. The upper and lower equalisation
valves open, allowing the pressure to equalise between the beds.
Once equalised the bed entering regeneration is depressurised. The oxygen adsorbed during the adsorption phase is vented to atmosphere via
an exhaust valve and silencer. The bed entering the adsorption phase is pressurised using a controlled flow of nitrogen gas from the nitrogen
buffer vessel (Back Fill) and a controlled flow of clean, dry, particulate free compressed air (Front Fill).
The CMS beds alternate between separation and regeneration modes to ensure continuous and uninterrupted nitrogen production.
The oxygen concentration in the nitrogen stream is analysed continuously. If the concentration exceeds the required production level, the
nitrogen outlet is closed and the gas is vented to atmosphere. Normal operation will resume when the purity recovers.

2.2 Unpacking the equipment
The generator is supplied in a wooden crate. It is recommended that the crate be moved into position using a forklift truck or pallet truck.
Remove the generator from the wooden crate using an overhead crane. The following illustrations give guidance on the safe slinging and lifting
techniques. Please refer to diagram A2 in Annex A.
Remove the silencer from the generator prior to unpacking it.
Care should be taken and inspection undertaken during unpacking to ensure that the product is not damaged.
Verify that all component parts have been supplied with the generator as listed below:
