Installation Unpacking and Installation
Although Peak Scientific takes every precaution with safe transit and packaging, it is advisable to fully inspect the unit for any signs of transit damage.

ANY DAMAGE SHOULD BE REPORTED IMMEDIATELY TO THE CARRIER AND PEAK SCIENTIFIC OR THE DISTRIBUTOR FROM WHERE THE UNIT WAS PURCHASED.
Following the un-packing instructions posted on the side of the crate. It will require 2 people to lift the crate clear and to maneuver the generator onto the floor. Thereafter the generator can be moved to its final location on the castors provided.

NOTE: - Included with the generator is a pack containing keys, manuals, service filters & fittings. Be careful not to discard these with the packing. Please save the product packaging for storage or future shipment of the generator.
Following installation of the unit, care should be taken to ensure that the waste bottle is NOT a sealed container, as this may cause possible pressure build-ups, explosion of the bottle, and consequential damage to the unit. Any bottle used should have a form of exhaust hole, before being fitted to this unit.

Electrical Connection
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.

Generator Environment

Generator Environment

The Generator is designed for indoor use only. The unit should be installed adjacent to the Mass Spectrometer it is supplying. If this is not convenient then the generator can be sited elsewhere, however, consideration should be made of the lengths of pipe runs as pressure drops can result from extended runs of pipe. Performance of the generator (like all sophisticated equipment) is affected by ambient conditions. Continuous operation in ambient temperatures exceeding 25ºC will lead to a reduction in capacity and prolonged operation in temperatures exceeding 30ºC will shorten the life of the unit. Note should also be taken to the proximity of Air Conditioning outlets. These can sometimes give rise to ‘pockets’ of air with high relative humidity. Operation of the generator within such a pocket could adversely affect its performance. Consideration should also be given to the air flow around the unit. It is recommended that an air gap of 75mm (3”) should be maintained down both sides and across the top of the unit. Please refer to the drawing below for the general dimensions of the generator. MAXIMUM AMBIENT CONDITIONS: 30ºC (dry bulb) 70%RH (Max.)

Principle of Operation

Peak Scientific Instruments NM30LA-MS The Nitrogen generator employs “Hollow Fibre Membrane” Technology to efficiently separate Nitrogen from other gases present in ambient air. An overview of this process can be seen below.

Pneumatic Diagram

Air is drawn into the system by the Compressor (1) and passed through the Cooling Coil (2) and the AFD – 3000 Micro Mist Filter (3) into the Membrane (5). After the Membrane (5) the gas is passed through a Reverse Acting Carbon Filter (6) to remove any remaining impurities and via the Non-Return Valve (Check Valve) (7) into the Receiver (10). The stored gas is regulated (11) to give the required output pressure and flow. Receiver pressure is measured (9) to allow the generator to un-load (4) and shut-down should demand cease. A Safety Relief Valve (8) is fitted to protect the system against over pressure. Gas is delivered out of the machine via the Outlet Port (12). Any moisture collected by the AFD – 3000 Micro Mist Filter (3) is expelled via the Drain Port (13).

Commissioning

Operator Training The NM30LA-MS Laboratory Gas Generator is designed specifically to minimize operator involvement. Given that the generator is installed as described in earlier sections and is serviced in accordance with the following maintenance recommendations then it should simply be a matter of turning the generator on. The generator will automatically produce the factory default flow and pressure noted below. NITROGEN OUTLET 30 litres per min (ATP) 100 PSI.G (680kPa)

Should the demand for gas be less than the rated flow then the generator will automatically regulate the internal pressure and cycle of the compressors as required. This should be all the input your generator requires from you, the only additional tasks required are, If at any time the generator begins to emit excessive noise or vibration, then it should be switched off and you should contact your local representative or the factory as soon as possible. Please ensure that both the drain ports at the rear of the generator are led to a suitable connection or container. It should be noted that the generator will liberate considerable amounts of water from these ports (approx. 1-2 litres weekly). If a container is used it should be emptied at regular intervals. Ensure that the generator is serviced in accordance with the following maintenance recommendations.

Maintenance Schedule

Routine Maintenance Servicing and/or repair of the Generator should only be undertaken by a TECHNICALLY COMPETENT PERSON, with the generator in its safely isolated condition. SAFELY ISOLATED CONDITION Definition: The unit is in a Safely Isolated Condition when it is disconnected from its application, fully de-pressurised and isolated from the Electrical Supply. Directions for isolating the generator are shown below. Isolating the Generator: a)Switch off the unit. b)Disconnect the unit from the mains supply. c)Ensure the internal pressure gauges (page 12) reads zero. (If gauge does not fall to zero, loosen outlet fitting slightly to allow trapped gas to escape). d)Disconnect from the application. Maintenance Schedule

Note: *Compressors can be re-fitted as an alternative to replacement up to a maximum of 3 times, this is a more cost effective solution, however a degree of technical expertise is required and can be time consuming. Service kits are available for all routine maintenance. Please contact Peak Scientific for further details.
