Unpacking
Although Peak Scientific takes every precaution with safe transit and packaging, it is advisable to fully inspect the unit for any sign of transit damage. Check ‘SHOCKWATCH’ label for signs of rough handling prior to un-packing –

Any damage should be reported immediately to the carrier and Peak Scientific or the Peak Partner from where the unit was purchased. Follow the unpacking instructions posted on the side of the crate. It will require two people to remove the unit from the shipping crate and to manoeuvre the Generator onto the floor. Please save the product packaging for storage or future shipment of the Generator. Note: Included with the Generator is a “Fittings Kit” containing a mains power lead for UK, EU or US and all the required fittings. Be careful not to discard these with the packaging.

Removing the generator from the crate
The generator weighs over 33kg and as such should be unpacked by two people using the following method. All the screws encircled in RED should first be removed from the shipping crate, there are approximately 8 screws. Now, with someone positioned at either side of the shipping crate, the top half of the crate can be lifted upwards and away from the rest of the crate. With the top of the crate removed the foam insert of top of the generator should also be taken off.

The generator can now be lifted out of the crate base and onto the floor. This should be done again with someone positioned at either side. There is a gap in the foam base for hand access; one hand should be positioned here underneath the generator and the other at the back supporting the weight. The generator should then be tilted back slightly and then up and out of the foam base and onto the floor.

Installation
Generator Environment
The Generator is designed for indoor use only. It should be installed adjacent to the application it is supplying. If this is not convenient then the unit 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. Please see the Tubing lengths section for further details. Performance of the Generator (like all sophisticated equipment) is affected by ambient conditions. 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 unit 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, at the rear and across the top of the unit. Please refer to the drawing below for the general dimensions of the unit. Maximum Ambient Conditions: 25°C (dry bulb) 70%RH (Max) Non-Condensing

Electrical Connection
Connect the Generator to an appropriate 110/230 volt single-phase supply, refer to the generator serial plate for input specification and ensure your supply matches the requirements If the appropriate power cord is not supplied: a new plug, rated to at least 10 amps, can be fitted by a qualified electrician. This unit is classified as SAFETY CLASS 1. 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):Neutral (N):Brown Blue or or Black White

Our electrical requirements are 110/230 VAC nominal +/- 10% depending on chosen model. Extended periods at these extremes can have a detrimental effect on the operation and life of the Generator.

Fuse
The generator protection fuse, in the pull out drawer of the mains inlet IEC connector located adjacent to the off/on switch. The replacement fuse must be rated T10AH250V

External Connections
The Nitrogen Generator should be connected to a clean, dry source of compressed air. A minimum pressure of 120 psi is required. Any doubts as to the suitability of the compressed air supply should be referred to the factory for advice. The generator has two ¼” BSPT bulkhead connections to the left side of the unit. The upper port is the Compressed Air inlet and the lower is the Nitrogen outlet. A ⅛” Swagelok fitting is supplied for connection to the application. There is no drain on this machine. Any moisture liberated by the filter separator is discharged through the high capacity exhaust system, where sudden reduction in pressure causes instant evaporation. The water vapour is safely removed from the unit by the ventilation system.

Start-up Procedure
With the generator installed as described earlier, connect power to the unit and turn it on. Disconnect the Nitrogen outlet connection to allow the generator to vent to atmosphere until the unit is stabilised. At Switch-on the exhaust valve will open and the generator will commence its venting cycle. This is to allow venting of any residual pressure in the system. The vent cycle may last up to 90 seconds. At the end of the vent cycle, the inlet valve will open and the normal operating cycle will begin. Pressure should begin to build on the gauge on the front panel, reaching 80 psi after approximately 10 minutes. The generator has been pre-set in the factory to give the specified output flow rate and pressure. Once the pressure in the Nitrogen receiver exceeds that setting the generator will stabilise and produce pure Nitrogen. Maximum purity will be achieved after around 8 hours. After this time the generator can be reconnected to the application. The design of the generator is such that it will deliver up to the rated output flow of Nitrogen at 80 psi. Should the demand for Nitrogen be less than the rated output flow, or indeed should the demand stop, the generator will continue to operate without any problems. The generator is protected from over-pressure and its normal operating cycle ensures frequent venting.

Normal Operation
Principal of Operation
The High Purity Nitrogen Generator utilizes a ‘Pressure Swing Adsorption’ (PSA) method to extract pure Nitrogen from air. This is where un-wanted gasses can be selectively adsorbed from compressed air into a porous carbon molecular sieve material (CMS). The Peak Scientific Instruments LTD. Generator utilizes a unique single column system where the column is alternately pressurised and vented under a finely tuned timing cycle. The rates of pressurisation and venting are accurately set which guarantees high purity better than can be achieved with a similarly sized traditional 2-column system.

Unusual Operation
If at any time the Generator begins to emit excessive noise or vibration, then it should be switched off and you should contact Peak Scientific or the Peak Partner from which the Generator has been purchased.
