General
This Service Manual conforms to the International Standard IEC 60601-1.
Read each step in every procedure thoroughly before beginning any test. Always use the
proper tools and specified test equipment. If you deviate from the instructions and/or
recommendations in this Service Manual, the equipment may operate improperly or unsafely,
or the equipment could be damaged.
Use only original Dräger parts and supplies.
The maintenance procedures described in this Service Manual may be performed by
qualified service personnel only. These maintenance procedures do not replace inspections
and servicing by Dräger Medical AG & Co. KGaA.
Strictly follow the Instructions for Use.
This Service Manual does not replace the Instructions for Use. Any use
of the product requires full understanding and strict observation of the
product-specific Instructions for Use.
Unless otherwise stated, reference is made to laws, regulations or
standards (as amended) applicable in the Federal Republic of Germany.

Function Description
1Handwheel settings
1.1 Handwheel set to “0” (off)
The fresh gas (→) flows from the vaporizer inlet to the vaporizer chamber bypass and through
the vaporizer chamber bypass from the outside to the inside. In parallel, a portion of the fresh
gas flows by way of an additional bypass and the flow control cone to the vaporizer outlet.
The vaporizer chamber is completely isolated from the gas flow by the valve (switching state a
and b). No anaesthetic can enter the flow control valves or the fresh gas.
A small hole in the valve (switching state a) vents the vaporizer chamber to prevent pressure
from building up.
As a result of temperature and pressure fluctuations, diffusion and pressure compensation
may cause small amount of anaesthetic vapour to escape. Ducts and buffer volume delay this
process.
If the Vapor 2000 is positioned at a tilt, anaesthetic may leak out of the vaporizer chamber
through the vent hole.

1.2 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.

1.3 Handwheel set to “ON” or higher
Between “0” and “ON” no concentration is defined in this range.
If the handwheel is turned to “ON” the fresh gas flows through the valve coupled to the
handwheel (switching states a and b) in the vaporizer chamber. The valve (switching state c)
closes the additional bypass.
Part of the fresh gas flows through the wick and is enriched with anaesthetic vapour (→).
The other part of the fresh gas bypasses the vaporizer chamber through the vaporizer
chamber bypass.
The two part-flows are combined downstream of the flow control slots and fed to the outlet.
The concentration is produced by the split of the gas and the saturation concentration of the
anaesthetic. The split is also influenced by the temperature compensation (thermal expansion
of different materials). When the temperature compensator heats up it opens the vaporizer
chamber bypass. When the temperature compensator cools down it narrows the vaporizer
chamber bypass. This compensates for the influence of temperature on the saturation
concentration.
The pressure compensation effectively reduces the pumping effect (see “Dependency on
alternating pressure during ventilation” on page 13).
