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:

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.

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.).

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).
