1.
Introduction
This document is intended for users of nitrogen generator models NiGen HF and
NiGen LCMS, and provides all information regarding installation, use and maintenance.
The generator is intended to be used as a source of nitrogen gas for laboratory
applications, including gas chromatography, ICP, LCMS, sample preparation,
etc..
The manual covers the following models:
As regards installation and maintenance, it is assumed that the user is familiar
with pneumatic circuit components, and in particular is aware of the safety aspects of compressed air and nitrogen.
The margin of the text contains the following symbols, indicating:
m
compulsory safety standards to be observed
c
electrical hazard
e
recommendations and important information
It is strongly recommended to carefully read all safety warnings (
par. 2.1.
) be-
fore carrying out any operation on the generator.

Safety
e
The unit must be installed and used in observance of the instructions in this booklet. Furthermore, use of the generator must be limited to that described in
Chapter 1 Introduction
. Failure to observe the foregoing will render the guarantee null and void and release CLAIND from all liability for direct or indirect damage or physical injury.
e
The user is responsible for asking local authorities if there are local safety regulations that are stricter than what is described in this manual.
2.1.
Warnings
m
Place the generators FAR FROM SOURCES OF HEAT
m
Place the generators in an environment PROTECTED AGAINST RAIN
AND WIND
c
NEVER OPEN the generator while it is connected to the electrical
mains: RISK OF FATAL INJURY BY ELECTROCUTION
e
Repairs and inspections must be carried out exclusively by QUALIFIED PERSONNEL: 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 time, it must be depressurised (par. 7.6. and par. 7.7.).
2.2.
Notes on the 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 nitrogen occurs in a normally ventilated environment to avoid the risk of accumulation
(par 4.2.1.).

Safety devices
MAXIMUM PRESSURE: the control system constantly monitors the pressure.
In case of anomalous pressure, a safety valve (which operates independently of
the control system) prevents it exceeding 10.5 bar (152 psi).

Installation area requirements
4.1.
Environmental requirements
m
Place the 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 environment where the generator is installed must be good ventilated to
prevent the risk of asphyxia and decreased the performance of the generator.
4.2.1.
Oxygen content in the ambient
m
If the generator and the point-of-use are located in different rooms,
the following minimum ventilation air flow must be provided to maintain acceptable oxygen content in the ambient. Don’t seal the rooms.
4.2.2.
Temperature
e
This paragraph is able only for these models: NiGen LCMS 40-1 and NiGen HF-1
m
Claind raccomanded to not go over the maximum environment temperature of 30°C for guarantee correct operations of the generator. If
this value is exceeded, in relation to the use of the generator, could appare the warning of maximum temperature of the compressor (E03)
(par.9.4.).
Are requires two openings of at least 0,5m2 to create a flow of air suffucient to
ensure air exchange.
It is also recommended to avoid danger of asphyxia.
Installation site enclosed, indoors
Relative humidity up to 80%, no condensation
Use temperature from 5°C to 35°C from 40°F to 95°F
Protection rating IP20
