Unpacking and Installation

UM – N*10DR – Rev 4

Unpacking and Installation 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 unpacking -

ANY DAMAGE SHOULD BE REPORTED IMMEDIATELY TO THE CARRIER AND PEAK SCIENTIFIC OR THE DISTRIBUTOR FROM WHERE THE UNIT WAS PURCHASED. Follow the un-packing instructions posted on the side of the crate. It will require two people to lift the crate clear and to manoeuvre the generator onto the floor.

Installation Removal of Transit Bracket Remove Rear Panel as follows:At the rear of the unit, turn the key in the lock anti-clockwise to unlock the rear panel. Hold the rear panel by the two handles and slowly swivel the bottom of it out and lower it until the top comes free from the chassis. Disconnect the plug at the LHS so that the rear panel can be completely removed.

UM – N*10DR – Rev 4

Disassemble Transit Bracket as follows – • Remove Screw 1 holding two pieces of transit bracket together. • Remove Screws 2,3,4,5,holding the Transit Bracket to the Compressors • Remove Screws 6,7 holding the Bracket to the internal side panels. • Remove transit bracket from unit.

Re-fit the rear panel in reverse order of removal. Important Note: The Transit Bracket must be removed prior to switching the unit on. Failure to do so will result in damage to the equipment. The Generator can now be moved to its final location on the castors provided. Note: - Included with the Generator is a pack containing hex key, manuals, fittings. Be careful not to discard these with the packing. Please save the product packaging and Transit Bracket for storage or future shipment of the compressor.

Installation Useful Information

UM – N*10DR – Rev 4

The diameter of the tubing which will be connected to the gas outlets is important and is determined by the length of tubing required. Failure to follow these recommendations could lead to accelerated compressor wear. < 10 meters. > 10 - 40 meters. > 40 metres. Use 6/4 (6mm O/D, 4mm I/D) P.T.F.E. tubing. Use 10/8 (10mm O/D, 8mm I/D). Please contact Peak with the relevant distance and we will calculate the flow resistance and the tubing size required.

A combination of 6/4 and 10/8 tubing may be used to ensure that there is no large diameter tubing within the lab (i.e. for the first 10 meters use 6/4 tubing and the final 20 meters use 10/8). Keep the connections and bends to a minimum. The imperial equivalents are:6/4 = 1/4” O/D, 3/16” I/D. 10/8= 3/8” O/D, 5/16” I/D.

Electrical Connection 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. The Electrical requirement is:EARTH/GROUND (E):LIVE (L):Neutral (N):230V AC (50/60 Hz), 8.4 Amps or or or Green Black White

Connect the compressor to a single-phase supply using the power cord provided.

Nitrogen N*10DR Nitrogen Generator
Generator Environment

UM – N*10DR – Rev 4

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 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 “Useful Information” 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° (dry bulb) 70%RH (Max) C

General Dimensions

Unit must always be placed on a level surface. Failure to do so will effect the performance of the Generator.

Operation

UM – N*10DR – Rev 4

The N*10DR generator is designed specifically to minimize operator involvement. Given that the system 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. Start Up Sequence When the unit is switched on the fans should power up and the display on the front panel should read –
Compressor Test

The system will now run through an automatic compressor check procedure. Each of the four compressors is tested in turn to ensure that it is working. The compressor check takes a minute or so and then the system will turn on fully and “PLEASE WAIT” will be displayed while pressure builds. The pressure can be monitored on the front panel gauge. Gas Generation When the system is running, the maximum number of compressors operating at any time is two. To ensure the longevity of the system, the compressors cycle in pairs, with a pair running for a three minutes while the other pair are turned off to cool, then the running pair are switched off to cool and the idle pair are switched on. The display will read Peak Scientific Mode: APCI

*Note: The outlet should be vented to atmosphere for at least 30 seconds to purge the system of impurities. If only a small volume of gas is being drawn from the system, it will automatically change into ESI mode. The display will read Peak Scientific Mode: ESI

Whilst running in this mode, if too much gas is then being drawn from the system, it will automatically change into APCI mode to meet the increased demand. The user can manually select ESI or APCI Compressor mode by pressing the relevant button on the control panel. If ESI mode is selected while the system requires two compressors, it will automatically return to APCI mode.

Additional Points

UM – N*10DR – Rev 4

Additional Points to Note Pressure / Flow Adjustment The system is configured in the factory to give standard Outlet Pressure and Flow Rate (see ‘Technical Specification’ page 6). These settings should NEVER require adjustment during normal operation. During service/fault diagnosis the settings can be changed by adjusting the pressure regulator and flow controller situated on the Electrical Panel (see page 18). Both will be in the locked position on receipt of the unit. To unlock and reset the following steps should be completed – Pressure Regulator •Pull adjustment knob upwards away from the bracket to release the lock. •Rotate to increase/decrease pressure. •Push adjustment knob downwards towards the bracket to lock. Flow Controller •Rotate knurled locking nut at base of adjustment knob to release lock. •Rotate to increase/decrease flow. •Rotate knurled locking nut at base of adjustment knob to lock. 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 your local representative or Peak Scientific as soon as possible. System Drain Please ensure that the drain port at the rear of the generator is led to a suitable connection or container make sure the container is not sealed tight. It should be noted that the generator will expel considerable amounts of water from this port. If a container is used it should be emptied at regular intervals. Service Ensure that the generator is serviced in accordance with the maintenance recommendations.

Maintenance

UM – N*10DR – Rev 4

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.

WARNING

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) Unplug the generator from the mains supply and remove the power cord from the rear of the unit. c) Ensure the pressure gauge on the front panel reads zero. (If gauge does not fall to zero, loosen outlet fitting slightly to allow trapped gas to escape.) d) Disconnect from the application. e) Important Note: Allow 10 minutes for unit to fully de-pressurise. After this time pull out the ‘Quick Release Ring’ on the Pressure Relief valve situated on the tank. Ensure tank is fully depressurised before releasing the ring. Maintenance Schedule
