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.

NG Range User Manual
Page 11 2014 © Peak Scientific - Rev. 6 – 10/01/14
Removing the generator from the 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 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.

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.

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):- Brown or Black
Neutral (N):- Blue or 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.

Service Plans
Peak Scientific offer two service plans. The Complete Service Plan, specifically
designed for Generators operated in critical environments, also includes full
breakdown cover, guaranteed response times and Generator upgrades if
available. Our Standard Service Plan, covering the basic needs of our
Generators, features special deals on spare parts and breakdowns.
If you want to know more about our Service Plan options and how we ensure
that your instrument can run with the maximum uptime and performance,
please contact us at [e-mail]
Cleaning
Clean the outside of the Generator only using warm soapy water and a clean
damp cloth. Ensure the cloth is thoroughly rung out to remove excess fluid
prior to use.
Cleaning should only be undertaken with the power switched
off and the power cord removed from the rear of the
Generator.
Under no circumstances should any solvents or abrasive
cleaning solutions be used as these can contain fumes that
could be harmful to the Generator.
