Safety
Risk of serious injury due to falling objects
When transporting parts/components and during product maintenance, there is a danger of injury
caused by loads slipping or falling.
► Carry small and medium-size components with both hands.
► Transport components that weigh more than 20 kg using suitable lifting gear.
► Wear safety shoes with steel toes in accordance with directive EN 347.
Risk of burns in case of contact with hot surfaces
For the operator's safety, the products are designed to avoid thermal risk. However, specific operat-
ing conditions may exist that require extra caution on the part of the operator due to the high temper-
atures (surfaces > 70 °C for parts inside the cover(s)).
► Wait for the product to fully cool down before working on it.
► Protective gloves must be worn in accordance with standard EN ISO 21420.
Health risk related to residual traces on the parts tested
A leak detection operation must be carried out under environmental conditions that do not present
any risks to the operator and the equipment. The user and/or integrator of the product are fully re-
sponsible for the operational safety conditions of the equipment.
► Do not test parts or equipment with traces of harsh, chemical, corrosive, inflammable, reactive,
► Apply the relevant safety instructions in accordance with local regulations.
Risk of pinching when handling the storage box cover
► Be careful not to leave your fingers under the cover when closing.
Health hazard in case of contact with components contaminated
The components of the pumping circuit and the analyzer cell are contaminated with the gases pump-
ed through the tested parts. These gases may be toxic, corrosive and/or reactive. Any contact with
the contaminated parts or by-products generated by the process may be injurious to health.
► Wear appropriate protective equipment when performing maintenance on the components of the
► Ventilate the area thoroughly or carry out the maintenance under an extraction hood.
► Do not eliminate the by-products/residue as common waste; have them destroyed by a qualified
Poisoning risk in case of gas leakage after maintenance
When connecting/disconnecting pumping line components (pumps, analyzer cell, vacuum block, pi-
pework, valves, etc.) for maintenance, the tightness of the installation is broken, potentially causing
leakage of hazardous residual gases (pumped gases for parts to be tested).
► During disassembly, always protect the bearing surfaces of the connecting flanges between the
► After reassembly, perform a tightness check on the pumping line of the detection system.
Risk linked to the various energy sources
Electrical circuit and other pressurized circuits as nitrogen are potential hazards.
► Always lock these sources of energy before working on the product.
