INSTALLATION
When performing the installation, please remind that if you pierce the FLAMEPROOF container, it will lose its properties
and its conformity to REGULATIONS.
TERMS and EXPECTATIONS: The installation of the SG895 probe, its ordinary and extraordinary maintenance, and
its out of service removal at the end of the functional life guaranteed by the manufacturer, must be carried out by
authorized and/or specialized personnel.
Do not allow it to become wet.
The probe can be seriously damaged when immersed in water. Remember that the probe has an EEX protection degree.
Do not drop it.
Heavy knocks or falls during transportation or installation can damage the appliance.
Avoid abrupt temperature fluctuations.
Sudden temperature variations can cause condensation and the probe could work poorly.

MAINTENANCE
The user periodically (every 6 months) must perform a check of the operation of the control unit by spraying
a suitable test gas at the base of the probes connected until the alarm condition is reached.
• At least once a year make a more accurate check by a specialist technician.
• Disabling the detector must be carried out by qualified personnel.
