IMPORTANT !
When the unit is out of service, dr ain all the water
contents from the circuits.
If the dr aining operati on is felt to be too much trouble, ethyl ene glycol
may be mi xed with the water in suitabl e proportions in order to
guarantee protec tion from freezing. In the cas e of a small water flow in
the rej ection exc hanger operating as evapor ator, and/or an excessi vel y
low inl et temperature, the ST 3 pr obe could trigger the antifreeze alar m.
If the mac hine is i nstalled in a glyc ol and water loop, it is possible to
modify the s et point (using the pass word) on the basis of the
percentage of glyc ol us ed (s ee the table below).
