Safety Instructions

J22 Analyzer Seals

The optical head of the analyzer interfaces with the process medium through a lens and pressure transducer in the cell tube
assembly. The lens and pressure transducer are considered to be the primary seals of the equipment. The ISEM interface module
assembly provides separation between the transmitter head and optical head, which is considered to be the analyzer’s secondary
seal. Although the J22 contains other seals to prevent the migration of process medium into the electrical wiring system, ifeither of the primary seals fail only the ISEM interface module assembly is considered a secondary seal.
All optical heads for J22 analyzers systems were assessed as "Dual Seal without Annunciation" devices. Refer to the markings on
the label for the maximum working pressures.
J22 Gas Analyzers with enclosed sample conditioning system with an optional heater require a suitable equipment certified seal
to be installed within 2 inches of the outer enclosure wall of the heating circuit.
For Class I Zone 1, installation seals are required within 2 inches of the analyzer transmitter housing. If the J22 analyzer
includes a heated enclosure, a suitable equipment-certified seal shall be installed within 2 inches of the outer enclosure wall of
the heating circuit as well.

2.8.2

Electrostatic discharge

The coating and the adhesive label are 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 besubjected to external conditions, such as high-pressure steam, which may cause a build-up of electrostatic charges on nonconducting surfaces. To clean the equipment, use only a damp cloth.

2.8.3
