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).
