Draining the
Vaporizer
Before draining a vaporizer, identify the filling system on the device as
one of the following:
• Open funnel system

When you have identified the filling system, locate the appropriate
procedure and read it entirely before draining the device.
WARNING: Do not inhale anesthetic vapors while draining the
vaporizer. Uncontrolled inhalation of anesthetic vapors is
injurious to health.
