Handwheel set to "T" (Transport)

When the handwheel is turned to "T" no fresh gas flows through the valve (switching state c)
to the flow control cone. The vent hole in the valve (switching state a) is closed. No anaesthetic
vapour can escape. The Vapor 2000 is safe from leakage even when tilted, and so can be
transported in any desired position.
Closing off the vaporizer chamber may lead to slight positive or negative pressure in the
event of ambient temperature and pressure fluctuations. As the temperature rises and/or the
air pressure falls (e.g. during transportation in direct sunlight or at high altitudes), a higher
pressure may build up. This pressure is adjusted to the ambient pressure by setting the
handwheel to "0" or by opening the filling system. Small amounts of anaesthetic vapour may
escape in the process.
