Introduction
The NG range of ultra high purity nitrogen generators have been designed primarily
for GC applications and other applications requiring the highest purity nitrogen.
These models provide a source of Nitrogen gas with other features including:
• Available with or without an external compressor
• Contains self-regenerating Carbon Molecular Sieve purification
• The most convenient method of laboratory gas supply
• Gas is supplied on demand so generator works to your schedule
• Remove the hassle and safety concerns with ordering and replacing pressurized
cylinder gas
• 12 month comprehensive on-site warranty
Delivering flow rates of 3000cc/min or 5000cc/min, these generators come in
two variants, the standard model and the enhanced (A) models which feature an
integrated compressor, removing the need for an external air supply to be present in
the lab.
To reach their ultra high purity nitrogen output these generators use Pressure Swing
Adsorption and Carbon Molecular Sieve. These separation technologies remove
oxygen and other impurities in air, delivering hassle-free, ultra high purity nitrogen,
on-demand for the lab.

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’ and ‘TIP-N-TELL’ labels for signs of rough handling prior to
unpacking.
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 to
the desired location.
Please save the product packaging for storage or future shipment of the generator.
Note: Included with the generator is a “Fittings Kit” containing mains power leads
for UK, EU & US and also all the required fittings and warranty registration card. Be
careful not to discard these with the packaging.

Installation
Generator Environment
The generator is designed for indoor use only. It should be installed adjacent to
the application(s) 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.
Performance of the generator (like all sophisticated equipment) is aected 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 aect 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 at the rear of
the unit. Please refer to the drawing below for the general dimensions of the unit.
Minimum Operating Ambient Temperature: 5 °C (41 °F)
Maximum Operating Ambient Temperature: 35 °C (95 °F)

Page 16
Removing the generator from the shipping crate
The generator weighs over 57kg 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 16 screws, and the front door should then be removed.
Now, with someone positioned at either side of the shipping crate, the top half of the
crate can be slid backwards 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 o.
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.

Generator Overview
General Dimensions
The generator must always be placed on a flat, level surface. Failure to
do so will aect the performance of the generator.

Page 18
Removal of Transit Brackets
The transit brackets must be removed prior to switching the unit on.
Failure to do so will result in damage to the equipment. This will void
the warranty on the Generator and will result in a chargeable repair.
To remove the transit bracket first remove the 11 screws on the front panel as shown,
then remove the front panel from the generator.
Now locate the red transit bracket attached to the compressor foot plate, and remove
the two screws on the bracket. Next remove the transit bracket by first lifting up and
then out of the generator.
Replace the front panel and secure it to the generator using the 11 screws that were
previously removed.
CAUTION

Page 19
Wall Mounting
The NG range generator is designed to be mounted against a wall for safety reasons.
Supplied in the generator fittings kit are all the fittings required to wall mount the
generator. Detailed below are the necessary steps to mount the unit to a wall.
Locate the screw in the top rear corner of the unit, beside the yellow warning label.
Remove the screw from the generator this should be repeated for the other side of the
unit, and retain.
Next, using the screw which was removed, fit the bracket and washers provided to the
generator. Again this should be repeated for the other side. The bracket is adjustable
to accommodate varying kickboard widths.
Finally, using the dimensions provided, fix the wall plugs to the wall, ensuring wall
plug is suitable for the type of wall. If not, use the correct type. Secure the generator
to the wall with the screws from the fittings kit.

Page 20
Rear 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
¹/8” 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.
