2.4 Dangerous areas
On the unit there are dangerous areas for electric risk and hot temperatures.
The unit can be closed by case panels; in this case the dangerous parts inside the unit are not accessible
from outside . Only qualified and trained personnel can remove the covering panels. The unit is supplied with the
cooling circuit already charged with pressure gas and therefore it is necessary to pay the maximum attention in order
to avoid accidental release of the gas in the atmosphere.
