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.

System The key indexed safety system employs a matching pin-and-socket
assembly to prevent inadvertent use of the wrong agent in a Vapor 19.1 or

you must have the appropriate keyed bottle adapter for the anesthetic
agent.
1. With the vaporizer in an upright position, turn the handwheel to “0”
(zero-point interlock) and make sure the button engages in the locked
position.
2. Attach the keyed bottle adapter to the appropriate empty bottle.
Tighten to assure airtight seal. Mark the bottle to indicate that it
contains a previously used anesthetic.
3. Insert the bottle adapter fitting into the drain port of the vaporizer.
The two holes in the adapter fitting must face the Teflon seal surface in
the drain port.
