OPERATING ENVIRONMENT
The units are designed for installation in closed environments in conditions of 'urban' ,
non-marine atmosphere with non-corrosive and non-dusty characteristics.
Under no circumstances the following concentrations of pollutants in the air, in which
the unit must operate, shall be exceeded:
SO
<0,02 ppm
2
H
S
<0,02 ppm
2
NO,NO
<1 ppm
2
NH
<6 ppm
3
N
O
<0,25 ppm

The unit should not be installed in locations characterized by the presence of
flammable gases or acidic or alkaline substances.
Otherwise the coils and the internal components of the equipment could suffer
serious and irreparable damage from corrosi

WARNINGS FOR THE QUALITY OF THE WATER CIRCULATING IN
THE COILS
It is recommended to perform an analysis of the water circulating in the coil focusing
on the research of the possible presence of bacteria (detection of iron bacteria and
micro-organisms that can produce H2S or chemically reduce sulphates) and on the
chemical composition of the water, to prevent corrosion and fouling inside the tubes.
The water circuit must be supplied and replenished with treated water that does not
exceed the threshold levels indicated below.
