Precautions
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.
IMPORTANT: Do not test the device using the gas tap as this does not necessarily provide sufficient
concentration to activate the main alarm.
TERMS and EXPECTATIONS: The installation of the CHCO gas detector, 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.
In order to achieve long and satisfactory use of your CHCO gas detector,, use it by respecting the
following precautions.
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 detector could work poorly.
Above about +40°C, the detector could become very sensitive, and generate false alarms.
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.
Cleaning
Never clean the device with chemical products. If necessary, wash with a moist cloth.

Operatingspecificationsof thegassensors
The ELECTROCHEMICAL CELL technology sensor has a duration of: 5 years.
The CATALYTIC technology sensor has a duration that can vary: from 5 to 6 years.
The sensor’s functioning temperature, independently of the technology used, ranges from -10°C to
+40°C
ATTENTION!
The CATALYTIC probe does not tolerate a gas detection exceeding 100% of L.E.L., with consequent
natural death of the sensor.
Each immediate puff of gas that exceeds 100% of L.E.L. takes away months of life from the sensor.
To test the toxic gas, issue gas from a pre-calibrated aerosol from 30 to 300 ppm, into the grey
sensor.
Please see point 6. Using other types of gas is useless and could damage the sensor.
The detector must be tested by simulating the presence of gas issuing it from a pre-calibrated
aerosol.
One per each type, explosive or CO.
