We recommend in particular to read carefully the safety warnings (par. 2.1.) be-
fore of performing any operation on the generator.

Safety
4
2. Safety
This generator can be installed in close proximity to the utilization without clas-
sifying the surrounding area as “dangerous”, because it is designed with all the
necessary precautions in order to guarantee maximum safety.
The instrument must be installed and used following the instruction of this Ma-
nual. Failure in following the foregoing will render the warranty null and void.
Claind disclaims any responsibility for damages to people or property resulting
from improper use, from modifications or repairs carried out by unauthorised
personnel or if the instructions of this booklet are not followed.
2.1. Warnings
m The generator must be positioned FAR FRO HEAT SOURCES.
The generator must be positioned in a environnement SHIELDED FROM RAIN
AND WIND.
c It is strictly forbidden to OPEN the generator when it is connected to
the power supply: FATAL ELECTROCUTION HAZARD
e Repairs and controls must be performed only by SPECIALIZED TECHNI-
CIANS: for any problem not solvable following the indications listed in the chap-
ter FAILURE DETECTION, please contact exclusively CLAIND technical service.
e Should the generator not been operative for a long time, it has to be convenien-
tly depressurized (see par. 6. .)
2.2. Considerations about use of Nitrogen
Nitrogen isn’t a toxic gas, but when the percentual in a closed environment as a
room exceed certain values, suffocation hazard may occur.
We recommend therefore to NOT INHALE directly the outlet gas and to not work
in close proximity of the Nitrogen flow.
It is anyway sufficient a normally ventilated room to prevent accumulation risks,
since the flow of the Nitrogen generator is really small.

2.3. Safety devices
m AXI U PRESSURE:
Never apply pressure on the gas outlets: risk of damaging the generator. More-
over, an applied pressure superior to 10 bar, will lead to explosion hazard due
to the structural failure of the components.
2.4. Technical assistance
e CLAIND disclaims any responsibility resulting from improper use of the genera-
tor.
Before of performing any intervention it is necessary to contact CLAIND technical
service.

4. Installation
4.1. Installation area requirements
4.1.1. Moisture and particulate
In order to avoid any risk of damages to the electronic component, it is recom-
mended to install the generator in a environment where relative moisture and
particulate concentration are limited.
Moreover, the generator must be protected from dripping, rain and wind.
4.1.2. Temperature
The temperature of the environment where the genertor is installed must be
between °C and 3 °C.
Please avoid proximity to heat sources and exposition to sunlight beams.
4.2. Positioning of the generator
4.2.1. Handling
The packed generator can be handled using suitable equipments, such as a
“transpallet” or a forklift truck. Once unpacked, it can be moved by its own whe-
els.
e The generator must always stand in vertical position, because it hasn’t been de-
signed to be layed.
4.2.2. Packing removal
The generator is delivered on a dedicated pallet.
Remove packing, paying attention to not damaging the panels of the generator.
The generator must be lifted from the pallet using dedicated equipment or even
manually by at least 4 people.
If possible, conserve the original packing to guarantee adequate protection to
the instrument in case of future handling.
4.2.3. Compressor block removal
e Before of the generator start-up, remove the compressor block. Failure in per-
forming this operation will damage or break the generator.

the ground cable.
3. Detect the right angled profile
(in red) that blocks the
compressor on the base of the
generator.
4. Unfasten the screws that block
it to the base (2).
5. Unfasten the screws that block
it to the compressor (1).
6. Remove the right angled
profile.
7. Fasten the screws to the
compressor(1).
8. Position the right
angled prifle on
the base of the
compressor in
correspondence of
the holes for the
blocking of the
screws.
9. Position the
screws (2).
10. Push the right
angled profile
toward the
generator (A).
11. Fasten the screws
(2).
12. Gently shake the
compressor to verify that it is free to move on the rubber feet and that it
doesn’t collide with the compressor block right angled profile.
13. Connect again the fan and the ground cable.
14. Fasten againg the rear lower panel.
The right angled profile must be mounted again in the correct way in case of
future handling.

4.4. Power supply
c For your safety it is mandatory to comply with following prescriptions.
Electric installation must comply with the law in force, particularly with the regu-
lation on the protection line.
c Advices for a correct installation:
• do not use extension cable, adaptor or multiple socket; when necessary, substi-
tute the Schuko plug with another adequate one.
• Always connect the protection conductor;
• the power socket has to be located in a easily accessible place.
CONNECTION
• Locate the fitting for the connection of the power cable on the rear of the gen-
rator.
• Before of connecting the cable, verify that the POWER switch is in OFF position.
• Connect the power supply cable (2m lenght, Schuko plug IEC320 C13)
4. . Warning
e In case that even momentaneus failures in gas supply (due to interruption of the
power supply, the intervention of a power protection, a failure of the generator)
aren’t acceptable, it will be opportune to forecast a pneumatic switch board that
allows the temporary insert of a secondary gas source more or less automati-
cally.
e As a precaution the restart of the generator after a interruption of the power
supply isn’t automatic, but manual on operator command.
e In case that the automatic restart of the generator is necessary after a black-out
during the operation, it is necessary to set this modality in the set-up software.
4.6. Disposal of the packing
It is recommedend to keep the original packing for possible future handling, as
it guarantees adequate protection to the generator.
