Safety instructions
In leak detectors fitted with atmospheric air purging, avoid performing
detection operations in non ventilated rooms. The helium concentration may
be too high.
Installation
(cont.)
The leak detector must be installed on a horizontal flat surface and never laid
on its side. Some models cater for other positions; these are described in the
operating manual.
The leak detector is Class 1 equipment and therefore must be earthed.
The user must check the electrical installation to which the leak detector is
connected:
- it must comply with current standards (IEC 364),
- it must have a standards compliant earth wire, properly connected to
earth.
Electric shock hazard on touching.
When the main isolator is switched to the «0» position, items located between
the mains connection and the isolator are still under mains voltage.
Disconnect the mains cable from all power sources before commencing any
maintenance work on the product.
Electric shock hazard.
Some components have capacitors charged to over 60VDC. When power
is switched off, they keep their charge for a time. Residual voltages from
the filter capacitors can cause electric shocks all the way back to the mains
plug. Wait 5 minutes after power-off before commencing any work on the
appliance.
A helium leak test must be performed in environmental conditions bearing no
risk to the user or equipment (atmosphere neither in flammable, nor explosive).
The user and/or OEM are ultimately responsible for ensuring proper safety
conditions apply to the working product. The manufacturer has no control
over the type of gas the detector is used with. Parts tested, equipment used,
and the plant itself must show no trace of aggressive, chemical, corrosive,
inflammable, reactive, toxic, explosive substances, neither condensable
vapors, even in tiny quantities.
These are hazardous substances, and the process user must take responsibility
for applying all relevant safety instructions in accordance with the legislation
in effect at the site.
The detector’s nitrogen purge system is not intended to dilute these gases.
The manufacturer can not be held liable and the guarantee is void if the
detector is used while these gases are present.
Lock out (LO/TO) of nitrogen purging circuit.
The user will need to provide a dedicated Nitrogen circuit, fitted with a
manual valve, that can be locked out within a radius of 3 m (10 ft) of the
equipment.
