Introduction
This document is aimed at the User of a hydrogen generator model in the series
Hydro200, and provides all information regarding installation use and mainte-
nance.
As regards the operations of installation and maintenance, it is presumed that
the manual user is experienced in the use of pneumatic components, and in par-
ticular is aware of all safety aspects linked to the use of hydrogen.
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
The generators in this series can be installed in the vicinity of the utilities without
the requirement for classification of the surrounding area as “hazardous”, provi-
ded that all necessary measures have been taken to guarantee the maximum
safety.
The unit must be installed and used in observance of the instructions in this boo-
klet. Failure to observe these instructions will render the guarantee null and void
and release CLAIND from all liability for direct or indirect damage or physical
injury.
2.1.
Warnings
m
Hydrogen is an extremely flammable gas that forms EX LOSIVE MIX-
TURES WITH AIR. If not aware of all safety aspects linked to the use
of this gas, consult the relative safety datasheet
m
lace the generators FAR FROM SOURCES OF HEAT
m
The generator must operate with its safety guard fitted: this guaran-
tees the correct circulation of air and prevents the formation of gas
pockets. For the same reason, NEVER LACE OBJECTS ON THE TO
VENTILATION GRILLE
m
lace the generators in an environment ROTECTED AGAINST RAIN
AND WIND
c
NEVER O EN 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 S ECIALIST ER-
SONNEL: in the event of faults impossible to solve according to one of the pro-
cedures in the TROUBLESHOOTING chapter, contact exclusively a CLAIND
technical service centre
e
If the generator is not to be used for a prolonged period of time, it must be ade-
quately depressurised (see par. 6.4. and par. 6. .)

Safety devices
MAXIMUM RESSURE: The maximum volume of hydrogen that can be stored
in the generator is 100ml . Maximum operating pressure is 4 bar.
There is a double pressure control.
• One is a pressure sensor, via the control system, which shuts down the genera-
tor when pressure value exceeds by 0. bar the set value;
• The other is a pressure switch, independent from the control system, which shu-
ts down the generator when pressure value exceed 4. bar;
HYDROGEN-OXYGEN MIXTURE: The formation of potentially hazardous
hydrogen-oxygen mixtures inside the generator is prevented by:
• Special electrodes (patented) for the production of hydrogen which prevent oxy-
gen from mixing with the hydrogen.
• A forced ventilation system prevents the formation of hydrogen pockets due to
possible gas leaks. Any significant gas leaks are also indicated by the control sy-
stem.

Installation
4.1.
Installation area requirements
4.1.1.
Humidity and dust
To avoid risks of damage to electronic components, install the generator in an
environment subject to limited relative humidity and low concentrations of dust.
The generator must also be protected against drips, rain and wind.
4.1.2.
Temperature
The ambient temperature in the generator installation area must be between
°C and 40°C.
Install away from heat sources. Avoid direct exposure to sunlight.
4.2.
Installation procedure
4.2.1.
Step 1: remove the packaging
Remove all packaging, taking care not to damage the generator panels.
If possible, store the packaging to ensure adequate protection when moved in
the future.
Ensure that the supply is complete (see section 3.1)
4.2.2.
Step 2: position the generator
Locate an installation area that meets the specifications listed in section 4.1.
Position the generator on a laboratory bench or on a Claind generator from the
series AirToc, AirToc SL, or NitroAir.
e
Handle with care: never tilt the generator and avoid impact with obstacles.
e
Ensure a clearance of at least 20cm cm at the rear of the generator.
e
Remember never to place objects on the top panel of the generator.
4.2.3.
Step 3: fill the demineralised water tank
• locate the demineralised water tank at the rear of the generator
• disconnect the tank by means of the quick coupling at the bottom of the tank.
• remove the tank
• unscrew the cap, fill the tank to 1 cm from the top edge and refit the cap
• refit the tank and connect the quick coupling
e
Use demineralised water with electrical conductivity no higher than
Installation
10
µS/cm (resistivity no lower than 0.2 M
Ω
cm) @ 20°C
e
The generator consumes approx. 1ml (1cc) of demineralised water per litre (Nl)
of hydrogen produced
e
On request, CLAIND can supply an external pump kit (see APPENDIX), which in
command by the generator enables automatic refilling of demineralised water.
4.2.4.
Step 4: Connect the hydrogen line.
• locate the coupling H2 OUT at the rear of the generator
• remove the cap using a 8mm hex key
• From those available in the connection kit, choose the coupling most suited to
the line used. The supply comprises couplings for connection to 1/8” copper pi-
pes or 2×1mm steel pipe
• Connect the line.
e
the hydrogen line must be able to withstand a pressure of at least 4. bar.
e
conserve the cap, as it is used in the event of future transport of the generator
(see chapter )
4.2. .
Step : connect the electrical mains;
• check that the mains specifications correspond to the data on the generator da-
taplate
• ensure that the POWER key is set to OFF.
• Make the electrical connection using the cable supplied with the generator (type
IRC3 0-Schuko, length 2m)
c
For reasons of safety, the following instructions must be strictly obser-
ved.
The electrical installation must comply with current standards, in particular re-
garding the protection line.
c
Recommendations for correct installation:
• do not use extension leads, adaptors or multiple sockets; if necessary, replace
the plug IEC3 0-Schuko with a more suitable version;
• always connect the protection wire;
• the mains socket must be located in an easily accessible position.
e
If a failure in gas supply (due to a power failure, activation of an electrical safety
device, or generator fault), even temporary, is not admissible, a pneumatic panel
should be envisaged, to enable provisional activation of a reserve gas source (to-
tally or partially automatic).
e
To ensure compliance with standards imposed by the Machinery directive, the
start-up of the generator after electrical power supply is restored cannot normal-
ly be automatic, and should be manually activated by the operator.
