1. Introduction
This docu ent is intended for users of nitrogen generator odels NiGen HF and
NiGen LCMS, and provides all infor ation regarding installation, use and ain-
tenance.
The generator is intended to be used as a source of nitrogen gas for laboratory
applications, including gas chro atography, ICP, LCMS, sa ple preparation,
etc..
The anual covers the following odels:
As regards installation and aintenance, it is assu ed that the user is fa iliar
with pneu atic circuit co ponents, and in particular is aware of the safety as-
pects of co pressed air and nitrogen.
The argin of the text contains the following sy bols, indicating:
m compulsory safety standards to be observed
c electrical azard
e reco endations and i portant infor ation
It is strongly reco ended to carefully read all safety warnings ( par. 2.1. ) be-
fore carrying out any operation on the generator.

2. Safety
e The unit ust be installed and used in observance of the instructions in this boo-
klet. Further ore, use of the generator ust be li ited to that described in
Chapter 1 Introduction . Failure to observe the foregoing will render the guaran-
tee null and void and release CLAIND fro all liability for direct or indirect da-
age or physical injury.
e The user is responsible for asking local authorities if there are local safety regu-
lations that are stricter than what is described in this anual.
2.1. Warnings
m Place t e generators FAR FROM SOURCES OF HEAT
m Place t e generators in an environment PROTECTED AGAINST RAIN
AND WIND
c NEVER OPEN t e generator w ile it is connected to t e electrical
mains: RISK OF FATAL INJURY BY ELECTROCUTION
e Repairs and inspections ust be carried out exclusively by QUALIFIED PER-
SONNEL: in the event of faults which cannot be resolved according to the pro-
cedures listed in the TROUBLESHOOTING chapter, contact exclusively our
authorized Technical Assistance.
e If the generator is not to be used for a prolonged period of ti e, it ust be de-
pressurised (par. 7.6. and par. 7.7.).
2.2. Notes on t e use of nitrogen
Nitrogen is not a toxic gas, but when the percentage in the air exceeds specific
values there is a risk of asphyxia.
Therefore NEVER DIRECTLY INHALE the gas produced and avoid working in the
vicinity of a flow of nitrogen.
However, given the low quantities produced, it is sufficient that the flow of ni-
trogen occurs in a nor ally ventilated environ ent to avoid the risk of accu u-
lation (par 4.2.1.).

2.3. Safety devices
MAXIMUM PRESSURE: the control syste constantly onitors the pressure.
In case of ano alous pressure, a safety valve (which operates independently of
the control syste ) prevents it exceeding 10.5 bar (152 psi).

4. Installation area requirements
4.1. Environmental requirements
m Place t e generators FAR FROM SOURCES OF HEAT, PROTECTED
AGAINST RAIN AND WIND, and SHOULD NOT BE EXPOSED TO THE
SUN.
e Failure to observe the precautions preclude the guarantee.
4.2. Environmental ventilation
The environ ent where the generator is installed ust be good ventilated to
prevent the risk of asphyxia and decreased the perfor ance of the generator.
4.2.1. Oxygen content in the a bient
m If t e generator and t e point-of-use are located in different rooms,
t e following minimum ventilation air flow must be provided to main-
tain acceptable oxygen content in t e ambient. Don’t seal t e rooms.
4.2.2. Te perature
e This paragraph is able only for these odels: NiGen LCMS 40-1 and NiGen HF-1
m Claind raccomanded to not go over t e maximum environment tempe-
rature of 30°C for guarantee correct operations of t e generator. If
t is value is exceeded, in relation to t e use of t e generator, could ap-
pare t e warning of maximum temperature of t e compressor (E03)
(par.9.4.).
Are requires two openings of at least 0,5
2
to create a flow of air suffucient to
ensure air exchange.
It is also reco ended to avoid danger of asphyxia.
Installation site enclosed, indoors
Relative umidity up to 80%, no condensation
Use temperature fro 5°C to 35°C fro 40°F to 95°F
Protection rating IP20

If the generator is located in a closed roo , to prevent the risk of excessive te -
perature increase of air, we reco end the following ini u ventilations:
The axi u difference between the environ ental te perature and the roo
te perature with the generator ust be 5°C.
if in the roo there aren’t windows ensure that there is an pening for the outlet
of the air of larger cross-section of the fan.

5. Installation
5.1. Generator positioning
5.1.1. Handling
e The generator ust always re ain in a vertical position as it is not designed to
be laid on its side.
Once unpacked, the generator can be oved on its wheels.
5.1.2. Packaging re oval
m Two people are required for t is operation
The generator is delivered packed in a crate. Use the rear wall of the crate as an
unloading ra p
e If possible, store the packaging to ensure adequate protection when oved in
the future.
5.1.3. Positioning
When choosing the installation area for the generator, take into account ini-
u clearances required for use and aintenance: ideally a free space should
be left of at least 50 c fro the front and rear panels. The clearance at the rear
of the generator, as well as for aintenance, is required to ensure efficient cool-
ing of the co pressor.
e The generator is also equipped with four adjustable stationary feet

5.2. Pneumatic connections
5.2.1. Nitrogen outlet
m T e distribution line must be made of pipe rated for a pressure of at
least 10.5 bar (152 psi).
The pipe dia eter ust be sized on the basis of the acceptable pressure drop
values of the utility. Pipelines with an internal dia eter of at least 8 are rec-
o ended (e.g. polya ide pipe 10x8 ).
e To ensure no inal purity of the delivered nitrogen is aintained ( ini ize con-
ta ination fro oil residue, dust, scaling and hu idity), it is reco ended to
use clean and/or treated pipelines for final gas distribution.
CONNECTION
• Locate the nitrogen coupling, arked “NITROGEN OUTLET” at the rear of the
generator.
• Connect the line.
5.2.2. Air outlet
Not applicable to NiGen HF-0, NiGen LCMS 40-0 and NiGen LCMS 100
m T e distribution line must be made of pipe rated for a pressure of at
least 10.5 bar (152 psi).
CONNECTION
• Locate the co pressed air coupling, arked “AIR OUTLET” at the rear of the
generator.
• Connect the line.
e The outlet air pressure is adjustable fro 0 to 8 bar
e The available outlet air flow depends on the nitrogen consu ption. Please refer
to the following tables

Not applicable to NiGen HF-0, NiGen LCMS 40-0 and NiGen LCMS 100
CONNECTION
• Locate the "DRAIN" outlet at the rear of the generator.
• Connect the condensation drain pipe (e.g., dia. 4 polya ide hose).
• Route the other end of the pipe into the condensate collection container.
m T e condensation is expelled by bursts of compressed air. If using a
flexible ose, make sure it is properly secured.
5.4. Electric power supply
c For reasons of safety, t e following instructions must be strictly ob-
served.
The electrical installation ust co ply with current standards, in particular re-
garding the protection line/ground wire.
c Recommendations for correct installation:
• do not use extension leads, adaptors or ultiple sockets;
• always connect the protection/ground wire;
• the ains socket and switch ust be located in an easily accessible position.
• if the provided power cable does not atch the local plug configuration, the
proper power cable with the appropriate configuration ust be obtained prior to
atte pting to apply power to the unit.
CONNECTION
• Locate power cable connector at the rear of the generator.
• Before connecting the cable, ensure that the POWER switch is set to OFF.
• Connect the power cable supplied with the generator.

5.5. Warnings
e If a failure in gas supply (due to a power failure, activation of an electrical safety
device, or generator fault), even te porary, is not ad issible, a pneu atic panel
should be envisaged, to enable provisional activation of a reserve gas source (to-
tally or partially auto atic).
5.6. Packaging disposal
It is reco ended to store the original packaging to ensure adequate protection
for the purifier when oved in the future.

6. Disassembly and transport
6.1. Disassembly
• Stop the generator (par 7.6.);
• wait for depressurization (about a inute);
• switch off the generator (par. 7.7.);
• disconnect the electric power cable;
• only for NiGen HF-1 and NiGen LCMS 40-1 , depressurize the air tank, re oving
the air outlet plug (par. 3.3.2.) and acting on the air outlet pressure regulator as
described at par. 7.9.2. Plug again the air outlet;
• carefully detach the pneu atic connections.
6.2. Transport
e Re e ber that during transport the generator ust always re ain in a vertical
position.
If conserved, use the original packaging; otherwise use a pallet of adequate di-
ensions to hold the generator, affixing instructions in visible locations, such as:
THIS WAY UP, KEEP IN VERTICAL POSITION.
