arranged on the water inlet and outlet in order to drain the liquid contained in the unit (to make the operation easier, it is advisable to install two

4.1.6
Air vent valve
The unit is equipped with an air vent valve that automatically eliminates the air accumulated inside the
circuit, avoiding: undesirable effects such as premature corrosion and wear, lower efficiency and reduced
exchange yield.
The device also has a safety function in that, in the event of a break in the exchanger, it allows the refrigerant
gas to escape into the external air, preventing it from being transported to the internal terminals.
It is possible to leave the valve in the closed position by closing the cap on the outlet; by loosening the cap
the valve remains in the open position and the air is discharged automatically.
If a water leak is noticed, it is mandatory to replace the component by unscrewing it with
a spanner, as shown in the image below.
