4. OPERATION GUIDE
(1) The (CO2) Leak Detector unit is not equipped with
anti-explosive designs and measures. Do not use
this unit in the environment with the burnable
gases.
(2) There are some environmental conditions that
might cause error reading:
Pollutant places.
Large temperature variation.
Places with high wind velocity.
Organic solvent, adhesive vapor, fuel gas and
vesicant will cause abnormal response from the
sensor. Try to avoid the environment involved
with this substance.
Places fill with high concentration of R744 gas.
