Precautions for protection system (The analyzer with FM-Y, CSA-Y does not
have the protection system.)
WARNING
When the cover of the protection system is uninstalled, use a gas detector to check that the
concentration of explosive gases in the ambient atmosphere is less than the allowable limit.
The protection system is a flameproof enclosure.
When handling the screws on the cover of the protection system, note the following to avoid
damaging the screws since they cannot be repaired.
•
Use a hex wrench (option) to tighten/loosen the hexagon socketset screw.
•
The cover should be placed in a clean plastic bag or on a clean space to prevent it from
contamination.
Before installing the cover, confirm that the body and screws are not contaminated. If they
are, make sure to clean them.
•
Since the screws are coated with MOLYKOTE, do not lubricate them.
•
When installing the cover, tighten the screws by hand; never use tools.

Precautions for hydrogen gas
When using hydrogen gas as the carrier gas, the FID or FPD combustion gas, install the analyzer
in a location equipped with a ventilator or where there is sufficient ventilation to ensure safety.
Check for leaks regularly to make sure there are no gas leaks from the pipe joints.
Supply hydrogen gas to this analyzer at 500 ±20 kPa to meet the explosionproof requirements.
