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 ‘SHOCK WATCH’ label for signs of rough handling prior to unpacking -

ANY DAMAGE SHOULD BE REPORTED IMMEDIATELY TO THE CARRIER AND
PEAK SCIENTIFIC OR THE OEM PARTNER / 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.

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 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.
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.

Installation
Useful Information
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.

User Manual
Installation
Generator Environment
The Generator is designed for indoor use only. It 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°C (dry bulb) 70%RH (Max)

General Dimensions

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

User Manual
Operation
Principle of Operation
The N*00DR 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 flows and pressures.

Start Up Sequence
When the unit is switched on the fans should power up and the display on the front panel should read –
Peak Scientific
Compressor Test

The system will now run through an automatic compressor check procedure. At start compressor will
build pressure into the storage tank and then Each of the four compressors are tested in turn to ensure
that it is working. You will witness pressure rise and fall on the front panel gauges during the
compressor test. The compressor check takes approximately four minute 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 gauges.

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 cycle 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: Dual

Note: The outlet should be vented to atmosphere for at least 5 minutes to
purge the system of impurities.
If only a small volume of gas is being drawn from the system, it will automatically change into single
compressor mode. The display will read –

Peak Scientific
Mode: Single

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

Operation
Additional Points
Pressure / Flow Adjustment
The system is configured in the factory to give standard Outlet Pressures and flows
(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. 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 authorised service provider or Peak
Scientific as soon as possible.
System Drain
Please ensure that the drain ports at the rear of the unit are led to a suitable
connection or container. 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.
NOTE: The container must NOT have an airtight seal.
Service
Ensure that the generator is serviced in accordance with the maintenance
recommendations (refer to maintenance schedule for details).

Maintenance
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.
