SAFETY NOTICE TO USERS These instructions must be read thoroughly and understood before installation and operation of your Peak Scientific NM360L. Use of the Generator in a manner not specified by Peak Scientific MAY impair the SAFETY provided by the equipment. When handling, operating or carrying out any maintenance, personnel must employ safe engineering practices and observe all relevant local health and safety requirements and regulations. The attention of UK users is drawn to the Health and Safety at Work Act 1974, and the Institute of Electrical Engineers regulations. WARNING: Nitrogen is not a poisonous gas, but if the concentration in the inhaled air becomes too high there will be a risk of asphyxiation.

AIR CONNECTION

The Nitrogen Generator should be connected to a clean, dry, OIL - FREE source of compressed air. A minimum pressure of 120 psig is required for efficient operation of the Generator. Any doubts as to the suitability of your compressed air supply should be referred to the factory for advice. A MAXIMUM OIL VAPOUR CONTENT OF 5 mg per m^3 is PERMISSIBLE Air Inlet and Nitrogen Outlet connections are at the rear of the generator in the middle right side of the panel. The Air inlet connection is the left port. 1/2” BSP female, outlet port is 3/8” BSP female. The generator is supplied with two Breathing Air pre-filters and an Activated Carbon post filter, which are fitted internally. The Breathing Air filters will drain moisture and are equipped with automatic drains. This is connected to the 1/4” BSP Female port at the bottom of the rear panel. Any bulk moisture in the inlet air will be trapped by these filters and released through this drain port, which should be led to a convenient place.

ELECTRICAL REQUIRMENT

Important Electrical Notice This unit is classified as SAFETY CLASS 1 equipment. THIS UNIT MUST BE EARTHED. Before connecting the unit to the mains supply, please check the information on the serial plate. The mains supply must be of the stated AC voltage and frequency. EARTH/GROUND (E): Green & Yellow or Green LIVE (L): Brown Black Neutral (N): Blue White Fuse 1.6Amp The generator protection fuse is located on the front panel left hand side next to on/off switch of the Generator Connect the generator to a single-phase supply using the power cord provided.

Principle of Operation

Principle of Operation

Peak Scientific Instruments Membrane Generators utilise Hollow Fibre Membrane Technology to efficiently separate Nitrogen from other gases present in ambient air. The membrane operates on the principle of selective permeation in that so-called “Fast” gases such as H2O, CO2 & Oxygen will permeate through the membrane wall whilst so-called “Slow” gases will not and continue along the membrane tube and are thus available for collection and use.

Air passes into the system via the Breathing Air Filter. This will prevent bulk moisture and harmful contaminants from reaching the Membrane. The clean air then passes into the Membranes where Oxygen, CO2 and Moisture are removed allowing High Purity Nitrogen to pass through. The Output Flow is regulated for pressure and then passed through an Activated Carbon Filter to ensure no carry-over of harmful contaminants

Commissioning

Commissioning

With the Generator installed as described earlier. Disconnect the Nitrogen Outlet connection to allow the generator to vent to atmosphere until the unit is stabilized then open the air supply. The Generator has been pre-set in the factory to give the specified output flow-rate and pressure. Once the Membrane reaches the design pressure the Generator will stabilise and produce pure Nitrogen. Maximum purity will be achieved after around 1 hour. After this time the generator can be re-connected to the application. The design of the generator is that it will deliver up to rated output flow of Nitrogen at 100 psig. Should the demand for Nitrogen be less than the rated output flow, or indeed should the demand stop the generator will Automatically go into stand by mode this will switch off inlet Air supply, and on demand of Nitrogen the pressure switch will detect and energize solenoid valve and generator will start to produce Nitrogen. The system is protected from over pressurising.

Maintenance Schedule

WARNING: Servicing and/or repair of the Generator should only be undertaken by a
TECHNICALLY COMPETENT PERSON with the Generator in a safely isolated condition.

Due to the simplicity of the design and the small number of moving parts the NM Series Nitrogen Generator will have a long and trouble free life. However as with all scientific and technical equipment it should be regularly inspected and serviced as below BA Inlet Filters RAC Filter Elements Every 12 – months Every 12 - months

BA Inlet Filter Elements
These should be changed at 12 months intervals. In addition filter bowls should be cleaned and, the operation of the auto-drains should be checked, if auto-drain requires replacing. Part # is (02-4485).

FAILURE TO FOLLOW THE PRESCRIBED MAINTENANCE PLAN WILL INVALIDATE THE PRODUCT WARRANTY The Air supply to the Generator MUST be turned OFF and the Generator MUST be de-pressurised prior to attempting to remove ANY filter bowl. Failure to do this may cause injury.
