The DFZ ZANOTTI units are built to keep the operators safe. The use of protec-
tion gloves is, in any case, fundamentally important during controls, repairs, and
maintenance for every action which the operator must carry out inside the unit,
whether when handling the evaporator or the condenser which can injure his
hands with their fins or to avoid burns caused by accidental contact with the unit's
hot parts.
6.1 Engine coolant
The DFZ ZANOTTI units, like all engines, are equipped with a cooling device. A
spill or release of coolant can cause severe burnings due to the fact that, under
normal operation conditions, such coolant is subject to high pressures and tem-
peratures in the engine and radiator.
Don't ever remove the cap from a hot radiator. If such operation should prove
absolutely necessary, unscrew it very carefully so as to allow pressure to stabi-
lize slowly and evenly.
6.2 Refrigerants
The refrigerant contained in the refrigeration system can cause serious injuries if
it should come into contact with any part of the body: burnings, frostbite and even
blindness, if it comes into direct contact with the eyes. That's why the regulations
applicable to the handling of refrigerants during maintenance operations provide
that the customer calls the nearest service center to have the unit service or
repaired.
6.3 Battery
It is strictly forbidden to smoke while checking the unit. In fact, the batteries
release small amounts of hydrogen which by igniting can cause the battery to
explode and the operator to be seriously injured or blinded.
