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, and as a result
of which BEINAT S.r.l. therefore disclaims any responsibility for possible damages caused to people,
animals or objects.
TERMS and EXPECTATIONS: The installation of the SG850 Probe, 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.
Avoid abrupt temperature fluctuations.
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.
