Installation precautions
•
This detector head in the flame proof enclosure must be installed near the CO2 gas cylinders or
at the joints of gas carrying pipes.
•
The detector must face down to cater for heavier than air gases.
•
CO2 is heavier than air, it has tendency to settle down. Hence, if you are using CO2 cylinder,
install the unit up to 30cm above floor.
Don’ts
•
Don’t use the unit in direct sunlight.
•
Don’t expose the sensor to gas concentration higher than its prescribed range.
•
Don’t immerse the unit in any liquid.
•
Don’t attempt to clean the detector from inside.
•
Don’t open the flameproof enclosure when gas is present.
•
Don’t switch high voltage or power loads through the relay, use only as potential free contacts.
