2.1 Safety precautions
Obligation to inform
Any person responsible for installing, using or maintaining the product must first read
the security instructions in this operating manual and comply with them.
It is the operating customer’s responsibility to protect all operators against the dan-
gers associated with the product, with the media pumped and with the entire instal-
lation.
Installation and use of the accessories
The products can be fitted with special accessories. The installation, use and refurbish-
ment of the connected accessories are described in detail in the respective manuals.
Only use original accessories.
Accessory part numbers: (see 10).
WARNING
Hazard associated with non-compliant electrical installation
Safe operation after installation is the operator’s responsibility.
Connect the product to an installation that is compliant with local safety standards.
Do not carry out any alterations or modifications to the product on your own initiative.
For specific questions, contact your service center.
WARNING
Electric shock hazard in case of contact
When the product's circuit breaker is set at "0", some internal components still have an
electrical charge.
Make sure that the mains connection is always visible and accessible so that it can
be unplugged at any time.
Disconnect the power cable from all power sources before starting any work on the
product.
WARNING
Other located hazardous energies
Electrical circuit and other pressurized circuits as nitrogen are potential hazards:
Always lock out these energy sources before working on the product.
WARNING
Risk associated with process gases
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 responsible for the operational safety conditions of the equipment.
Therefore the user of the detector must:
not test parts or equipment with traces of harsh, chemical, corrosive, inflammable, re-
active, toxic, or explosive substances, nor condensable vapours even in small
amounts. Do not use the nitrogen purge system to dilute these hazardous products:
that is not what it is intended for!
apply specific safety instructions in accordance with local regulations. For more infor-
mation, contact your service center.

Safety

The potential hazards for a leak detector involve electricity, the tracer gas, the pres-
surised nitrogen supply and the lubricant (for the Wet models).
●Only qualified personnel trained in safety rules (EMC, electrical safety, chemical pol-
lution) may carry out the installation and maintenance described in this manual. Our
service centers can provide the necessary training.
●Do not remove the blanked-off flange from the inlet port while the product is not in use.
●Do not expose any part of the human body to the vacuum.
●Comply with all safety and risk prevention instructions in accordance with local safety
standards.
●Regularly check compliance with all precautionary measures.
●Do not turn on the product if the covers are not in place.
2.2 Protective equipment
In some situations, personal protective equipment must be worn when handling the de-
tector and its components. Customers must provide operators with the necessary equip-
ment. This equipment must be checked regularly and used in accordance with the sup-
plier's recommendations.
NOTICE
Wet Model: Filling with oil
Oil must be added to the primary pump before the detector is switched on.
DANGER
Health hazard in case of contact with the operating fluid
Contact with or inhaling products such as oil from the primary pump can cause irritation.
Wear appropriate protective equipment when carrying out maintenance or adding/
draining oil.

WARNING
Risk of injury through falling objects
When transporting parts/items by hand, there is a danger through loads slipping and fal-
ling down.
Carry small and mid-size parts/items two-handed.
Carry parts/items > 20 kg with a suitable lifting device.
Wear safety shoes with steel toe cap according to directive EN 347.
WARNING
Risk of injury through hot surfaces
The products are designed so as not to present a thermal risk for the operator's safety.
However, specific operating conditions may exist that require extra caution from users
due to the high temperatures (surfaces > 70 °C for parts inside the covers):
Leave the part to cool before working on the product.
If necessary wear protective gloves according to directive EN 420.
CAUTION
Risk of pinching
When handling the storage tank cover, there is a risk of fingers becoming pinched.

2.3 Proper use
●The leak detector is designed to detect and/or quantify a possible installation or com-
ponent leak by searching for the presence of a tracer gas in the pumped gases.
●Only the tracer gases identified in this manual may be used.
●The parts to be tested must be clean and dry.
●The leak detector may be used in an industrial environment.
2.4 Improper use
Improper use will cause all claims for liability and warranties to be forfeited. Improper use
is defined as usage for purposes deviating from those mentioned above, especially:
●pumping harsh, chemical, corrosive, inflammable, reactive, toxic or explosive fluids,
●pumping condensable liquids or vapours,
●pumping dust or solids,
●use in areas where there is a risk of explosion,
●analysis of gas with a hydrogen concentration higher than 5 %,
●testing parts that are soiled or that have traces of water, vapours, paint, detergent or
rinsing products,
●use of accessories or spare parts that are not listed in this manual.
The detector is not designed to carry people or loads and is not for use as a seat, step-
ladderor any other similar purpose.
NOTICE
EC conformity
The manufacturer's declaration of conformity becomes invalid if the operator modifies
the original product or installs additional components.
Following installation into a plant and before commissioning, the operator must check
the entire system for compliance with the valid EU directives and reassess it accor-
dingly.
