CHECK the integrity of the unit after having removed it from the box.
Check that the data written on the box correspond to the type of gas used.
When doing the electrical connections, follow the drawing closely.
Any use of the detector for purposes other than the intended one is considered
improper,andasaresultofwhichBEINATS.r.l.thereforedisclaimsanyresponsibility
for possible damages caused to people, animals or objects.
TERMS and EXPECTATIONS:TheinstallationoftheSG544Probe,its ordinary and
extraordinary maintenance, every six months, and its out of service removal at the
end of the functional life guaranteed by the manufacturer, must be carried out by authorized or specialized
personnel.
Do not allow it to become wet.
The control unit can be seriously damaged as it is not waterproof either when immersed in water or exposed to high
levels of humidity.
Do not drop it.
Heavy knocks or falls during transportation or installation can damage the appliance.
Avoidabrupttemperaturefluctuations.
Sudden temperature variations can cause condensation and the control unit could work poorly.
Cleaning
Never clean the device with chemical products. If necessary, wash with a moist cloth.

WARNING!
The CATALITIC sensor has a life span of 5 to 6 years in clean air.
The working temperature of the probe recommended is from -10 ° C to + 50 ° C.
Every puffy snapshot of gas over 100% of L.I.E. Takes months off the sensor.
Each immediate puff of gas that exceeds 100% of L.E.L. takes away months of life from the sensor.
The detector must be tested by simulating the presence of gas by issuing it from a pre-calibrated testing aerosol.
Important:
The test of operation and eventually offset cancellation must be performed at least once a year, by a qualified
technician.
