NOTICE under no circumstances does the unit have to be operated with water circulating on the heat exchanger whose characteristics are different from
those indicated in the table WATER CHARACTERISTICS, under penalty of the warranty expiration. Aermec cannot be held responsible for any malfunction
of the units which are operated with water whose characteristics are outside the limits in the table WATER CHARACTERISTICS and for their consequences.
It is of fundamental importance to keep the oxygen concentration in the water under control, especially in open vessel systems. This type of system, in
fact, is very sensitive to the phenomenon of extra-oxygenation of the water (an event that can be encouraged by the incorrect positioning of some com-
ponents). This phenomenon can trigger corrosion processes and subsequent drilling of the heat exchanger and pipes.
