Installation of the device
The following checks and tests must be carried out before commissioning the equipment:
1. Inspection of the protected area
2. Inspection of mechanical components
3. Checking the integrity of the protected area
After removing the product from the packaging, the temperature label must be checked to see
if the maximum permitted temperature limit 45°C was not exceeded during transport or other
handling. The temperature label becomes irreversibly black as the temperature increases. It is
generally recommended that no more than one indicating circle turns black which means the
temperature did not exceeded 40°C. If more than three indicating circles turn black, its
recommended to check the extinguisher level using the web interface by going to the Status
menu and check if the extinguisher indicator panel is still blue = OK.
When exceeding 49°C, i.e. more than 4 indicator cirlces turn black, it is likely that there was
an increase in a pressure in the tank due to the conversion of liquid fire extinguisher into a
gaseous state and probably also a leak. If this temperature has been exceeded, but the water
level is fine, we recommend an optical inspection of the LES-RACK device to see if the
