Working conditions
The device is intended for installation in an area protected against weather conditions class
3K3 according to ČSN EN 60721-3-3 with a temperature range of +5°C to +45°C. The
correct function of the device is conditioned by the working position of the device and its
location in a closed, protected space. The working position must always be horizontal, the
control panel of the device must be easily accessible. The device must be placed in the
highest possible place of the protected area. The working capacity of the device is guaranteed
in the temperature range from +5°C to 45°C with a maximum humidity of 85% and in an
environment where moisture condensation does not occur. Checking whether the maximum
permitted temperature has not been exceeded in the Device assembly chapter
assembly
chapter
.
WARNING:
If the temperature of the device exceeds 45°C, there may be an uncontrolled
leakage of fire extinguishing agent through the safety pressure valve. This is a
consequence of the high temperature of the fire extinguisher in the tank, during which a
gradual change of state from liquid to gas can occur. The result is an increase in pressure
in the tank.
