2.3 Product safety
The J22 TDLAS Gas Analyzer is designed in accordance with good engineering practice to meet state-of-the-art
safety requirements, has been tested, and left the factory in a condition in which it is safe to operate.
It meets general safety standards and legal requirements. It also complies with the EU directives listed in the specific
EU Declaration of Conformity. Hauser confirms this by affixing the CE mark to the analyzer system.
2.3.1 General
• Adhere to all warning labels to prevent damage to the unit.
• Do not operate the device outside the specified electrical, thermal and mechanical parameters.
• Only use the device in media to which the wetted materials have sufficient durability.
• Modifications to the device can affect the explosion protection and must be carried out by staff authorized to
perform such work by Hauser.
• Only open the controller cover if the following conditions are met:
• An explosive atmosphere is not present
• All device technical data is observed (see nameplate)
• An electrostatic charge (e.g., caused by friction, cleaning or maintenance) is avoided on the attached
stainless steel nameplate, if present, and on painted metallic housings that are not integrated into the local
potential equalization (ground) system
• In potentially explosive atmospheres:
• Do not disconnect any electrical connections while the equipment is energized.
• Do not open the connection compartment cover when energized or the area is known to be hazardous.
• Install the controller circuit wiring according to the Canadian Electrical Code (CEC) respective National Electrical
Code (NEC) using threaded conduit or other wiring methods in accordance with articles 501 to 505, and/or IEC
60079-14.
• Install the device according to the manufacturer’s instructions and regulations.
• The flameproof joints of this equipment are outside the minimums specified in IEC/EN 60079-1 and shall not be
repaired by the user.
2.3.2 General pressure
The system is designed and tested with appropriate margins to ensure that is it safe under normal operating
conditions, which include temperature, pressure, and gas content. The operator is responsible for ensuring that the
system is shut off when these conditions are no longer valid.
2.3.3 Electrostatic discharge
The coating and the adhesive label is non-conducting and may generate an ignition capable level of electrostatic
discharge under certain extreme conditions. The user should ensure that the equipment is not installed in a location
where it may be subjected to external conditions, such as high pressure steam, which may cause a build-up of
electrostatic charges on non-conducting surfaces. To clean the equipment, use only a damp cloth.
2.3.4 Chemical compatibility
Never use vinyl acetate or acetone or other organic solvents to clean the analyzer housing or labels.
2.3.5 Canadian Registration Number
In addition to the requirements above for general pressure safety, Canadian Registration Number (CRN) systems
must be maintained using CRN approved components without any modification to the sample conditioning system
(SCS) or analyzer.
2.3.6 IT security
Our warranty is valid only if the device is installed and used as described in the Operating Instructions. The device is
equipped with security mechanisms to protect it against any inadvertent changes to the settings.
IT security measures, which provide additional protection for the device and associated data transfer, must be
implemented by the operators themselves in line with their security standards.
