8.10 Non-condensing gases
i The drain valve (V6) for non-condensing gases opens
if the pressure in the refrigerant cylinder is higher
than the set opening pressure (normally between 12
and 14 bar).
i The pressure of the internal refrigerant cylinder in-
creases during the recovery phase and when prepar-
ing the refrigerant.
i The safety valve (V5) opens at a factory set pressure
(approx. 18 bar) to limit the pressure in the internal
refrigerant cylinder.
