i To ensure that the valve remains in good working
condition, periodically make it trip by pulling the
metal ring at the top.
i While doing this, make sure that the pressure in the
cylinder is at least 8–10 bar.
i The valve should open sharply and then close
firmly as soon as the metal ring is released.
! This action must be quick, and do not repeat it
until only non-condensable gas is purged, with no
refrigerant.
i The frequency depends on the valve condition,
and specifically on its cleanliness, which normally
depends on whether there are residues in the
cylinder or not.
