2. Safety
These generators can be installed next to the users without having to classify
the nearby area as “dangerous”, since it has been designed with all the neces-
sary precautions to guarantee maximum 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. arnings
m Place the generators FAR FROM SOURCES OF HEAT
m Place the generators in an environment PROTECTED AGAINST RAIN
AND IND
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
procedures listed in the TROUBLESHOOTING chapter, contact exclusively our
authorized Technical Assistance.
e If the generator has not to be used for a prolonged period of time, it must be
depressurised (par. 6. .)
2.2. Consideration on the use of nitrogen
Nitrogen isn’t a toxic gas, but when the percentual content of the air exceed de-
terminated values suffucation risk can occur.
We recommend therefore to not breath the gas directly and not to work in the
nearby of the Nitrogen flux.
Due to the low quantities of Nitrogen produced, a normally ventilated enviro-
ment is anyway sufficient to prevent the accumulation risk.

2.3. Safety devices
m MAXIMUM PRESSURE:
The maximum applicable compressed air pressure to generators is 10 bar. Ple-
ase pay attention that this value doesn’t exceed in order to avoid explosion risk
due to the structural failure of the components.
Pressure in the built-in reservoir is limited by a safety valve.
2.4. Technical assistance
e CLAIND disclaims any liability for any damages caused from improper use of the
generator.
Please contact CLAIND Service center before of any kind of intervention.

4. Installation
4.1. Installation preparation guide
4.1.1. Moisture and particulate
In order to avoid damages to the electronic components, we recommend to in-
stall the generator in a area where the relative moisture and the dust concentra-
tion are limited.
Moreover, the generator must be protected from dripping, rain and wind.
4.1.2. Temperature
Environmental temperature of the area of the installation must be between °c
and 40°c.
Please avoid proximity to heat sources. Please avoid the direct exposition to sun
beams.
4.2. Generator positioning
4.2.1. Handling
The packed generator can be handled using an adequate instrumentation, such
as a transpallet or a fork lift. Once unpacked, it can be moved by his own wheels.
m If suddenly moved the generator could fall and generate damage to
things or persons.
e The generator must be always kept in vertical position since it has not been de-
signed to be layed down.
4.2.2. Unpacking
The generator is shipped on a dedicated pallet.
Please remove packing paying attention not to damage the panels of the gene-
rator.
When possible, please keep the original packing to guarantee an adequate pro-
tection of the generator in case of future handling.

4.2.3. Remove the generator from the pallet
The generator removal from the pallet can be performed using the two eyebolts
included in the supply. These must be mounted on the top of the generator in-
stead of the two black plastic screws (following picture).
4.2.4. Positioning
The choice of the installation area of the generator must consider a minumum
access space for the user and for the maintenance: we reccomend to let a free
space of at least 0 cm both from the front panel and from the back panel.
4.2. . Assembly stabilizers
m GENERATOR UNSTABLE,to avoid damage caused by the overturning of
generator on people or things Claind has planned the assembly of the
stabilizers.
Assembly the feet (D) with the stabilizer brackets (C).

Use a allen key 4 mm to screw the feet and lift the generator from ground.
e Claind disclaims any liability for damage to things, animals and people caused by
the overturning of generator caused by a lack of stabilizers.
4.3. Pneumatic connections
The picture shows the elements that constitute a tipycal Nitrogen generation
plant. The fittings for pneumatic connection of the various components of the
plant (Nitrogen generator, compressed air reservoir, user) are located on the
back of the generator. The external air reservoir must be used only when the
tubes that connect it to the machine exceed 0 m lenght. It is possible to have
a longer line using tubes with nominal diameter > 8mm.

e For an easy installation, we recommend to use flexible polyammide hose. The
generator is supplied along with automatic fittings for polyammide tube 8 x 10
mm. diameter. .
4.3.1. Nitrogen outlet
The generator produces Nitrogen at a set purity (between 97% and 99,99%) ac-
cording to the needs of the user in phase of purchase order. The generator is
set in CLAIND facilities at the requested purity and can’t be reset by the user at
a different purity without the intervention of qualified CLAIND technician.
Nitrogen flow rate is depending from the model and from the requested purity.
Outlet pressure depends from the minimum intake compressed air pressure.
You can consider that the maximum pressure of Nitrogen is about 1, bar less
than the intake compressed air pressure.

Nitrogen Generators Nitro35 Nitro70

e During the first start-up, the Nitrogen reservoir will be full of air: the final purity
will be reached only when the total volume of air will be purged with the Nitrogen
fluxed by the generator. The requested time for this operation depends from the
model of the generator, from the requested purity of the Nitrogen as well as
from the volume of the reservoir itself.
CONNECTION
• Locate Nitrogen connection, that is indicated by the script NITROGEN on the
back of the generator;
• take the fitting (1), and mount it;
• connect the line.
e We recommend to insert an on-off valve on the flow on the outlet line.
4.3.2. Air inlet
The specification the inlet compressed air are very important for the performan-
ce and for the working life of the Nitrogen generator.
In addition to the minimum requirement of pressure and flow rate (specific of
the model of the generator), compressed air must comply to following specifica-
tion:
(ISO 8 73-1; class 1-4-1):
Dew Point< 3° C
Max. oil content:< 0,01 mg/m
3
Max. particulate concentration (0,1 µ m diameter)< 0.1 mg/m

e In case of utilization of a poor quality air, permanent damages to the generator
can occur. In this case, Claind won’t be liable for the damages and the costs of
the possible reparation will be charged to the Customer.
e Puirty of produced Nitrogen decreases as the pressure of the compressd air de-
creases. It is highly recommended to install a reservoir in case that the line isn’t
adequately dimensioned. In case of any need of clarification, please do not he-
sitate to contact CLAIND for other suggestion on the kind of compressed air
plant (compressor, dryer, filters and reservoir) adequate for the specific applica-
tion.

4.4. arning
e In case of non admissibility of a lack of gas supply (due to different causes such
as interruption of power supply, intervention of power supply protection, failure
of the generator), even though momentaneus, it would be opportune to forecast
a pneumatic distribution panel that allows the momentaneus and more or less
automatic insert of a spare gas sources.
e As a precaution, the restart of a generator after the restoration of power supply
isn’t automatic, but manual on command of the operator.
e When the automatic start of the generator after a black-out is necessary, it is
necessary to set this command in the set-up program
4. . Packing disposal
It is recommended of keeping the original packing for possible future movimen-
tation, since it guarantees an adequate protection to the generator.
