2.2.3 Drain Plug
wWarning: Draining the vaporizer may result in rapid loss of pressure and/or agent which could lead to
injury to the operator.
A drain plug is located at the base of the vaporizer as illustrated on Fig. 2. The drain plug must not be
removed except at an Datex-Ohmeda Authorized Service Center.
2.2.4 Power Supply Connector And Battery
The electrical power supply connector is located in
the base of the vaporizer as illustrated on Fig. 2.
If the mains power supply fails, a Duracell 1604
or VARTA Energy 2000 battery incorporated in

O & M Manual Part No. 1107-0622-000 August 2001
2.2.5 Equi-Potential Stud
The equi-potential stud Yis located on the top of the vaporizer. It provides a means of connecting a
vaporizer to the anesthesia system to minimize any electrical potential difference between the vaporizer
casing and the anesthesia system.
2.2.6 Sump
The sump provides a means of containing the agent and includes the agent filling port, the drain, the
heaters and the agent level sensor.
The sump has a total nominal capacity of 390 milliliters (ml) which consists of a nominal 330 ml indicated
volume and a nominal 60 ml reserve.
2.2.7 Heater Elements
Two 100W heater elements, located in the base of the sump, heat the agent to a nominal 39°C (102°F) to
generate the working pressure.
Two 100W heater elements located in the upper part of the vaporizer help to prevent condensation of the
anesthetic agent in the vaporizer.
The current supplied to power the heaters alternates between the two heaters in the sump and the two
heaters in the upper part of the vaporizer. This minimizes the current requirement.
The casing of the vaporizer is normally warm to the touch while it is connected to the electrical supply.
2.2.8 Monitors
Electro/mechanical monitors are incorporated to monitor the fresh gas/agent vapor pressure balance and
the agent volume.
The monitors control the operational status display and activate the appropriate alarm indication if a
monitored parameter malfunction is detected.
2.2.9 Agent Level Sensor
An agent level sensing probe is mounted in the sump to measure the agent level. When the sump contains
between 60 and 390 ml of agent, the LCD level display indicates the level of agent in the sump. If the agent
level decreases below 60 ml, the amber LOW AGENT light on the display panel flashes and the auditory
alarm is activated. If the agent level decreases below approximately 20 ml,
the red NO OUTPUT light flashes and the auditory alarm is activated. Vapor output then ceases.
2.2.10 Tilt Switch
If the vaporizer is tilted for 10-15 seconds while it is in operational mode and delivering vapor, vapor
delivery will be stopped, as indicated by the flashing No Output light and auditory alarm.

3.3.3 Agent Level Display
The LCD agent level display consists of a series of bars which
indicate the nominal volume of agent in the vaporizer sump.
The symbol denotes a 390 ml volume of agent and the
symbol denotes a 60 ml volume of agent in the sump.
Fig. 6 Operational
As the sump fills, the first agent level indicating bar appears in the LCD volume display when there is
between 60 and 80 ml of agent in the sump. As the level increases more bars are displayed as illustrated on
Fig. 6 and as the level decreases less bars are displayed.
When the bars are either level with or below the <, the sump can accommodate 240 ml of agent, which is
one full bottle. When there are no bars visible, as illustrated on Fig. 7, the Low Agent Level alarm is
activated as described in Section 3.3.4.
Note: The agent level display is calibrated to be most accurate when the vaporizer is in a perfectly level
position. Deviations from a level position affect the accuracy of the agent level display and may activate the
LOW AGENT level alarm.

3. A power failure of longer than 10 seconds duration occurs.
4. An internal malfunction is detected.
The alarm consists of a flashing red NO OUTPUT light
accompanied by short tone operation of the auditory alarm
which is a repetitive 0.5 seconds ON and 0.5 seconds OFF.
The alarm indicates that the vaporizer has closed down and
is no longer delivering any vapor.
Fig. 8 No Output
If the NO OUTPUT alarm occurs while the vaporizer is in use, the vaporizer dial must be turned to q. This
mutes the auditory alarm and illuminates the red light continuously. Either an alternative vaporizer or an
alternative method of anesthesia must be used.
If the NO OUTPUT alarm is activated as a result of a power failure and
the dial is at qwhen the power supply is restored, the alarm and
display test is activated and then the vaporizer returns to either the
WARM-UP or the OPERATIONAL mode.
If the dial is not at qwhen the power supply is restored, the NO
OUTPUT alarm continues and can only be cancelled by turning the dial
to q. In this condition the alarm and display test is not activated and
the vaporizer returns to either the WARM-UP or the OPERATIONAL
mode after a 10 second delay.

wWarning: When the vaporizer is in use, do not fill the vaporizer if the following conditions apply:
• The dial setting is more than 8% at flows of 8 liters/minute or above.
• The vaporizer is subjected to any high back pressure.
• The Suprane™ (desflurane) has been refrigerated or chilled below 18°C.
Failure to comply with this warning may result in a temporary decrease in delivered concentration and
activate the NO OUTPUT alarm.
wWarning: The vaporizer must be filled when it is in an upright position. Failure to do so may result in
the vaporizer being over filled.
wWarning: The vaporizer must only be filled when it is connected to the electrical supply. This enables
the agent level on the agent level display to be observed. Do not attempt to fill the vaporizer when the
level display indicates that it is full.
The D-Tec Vaporizer must only be filled when it is in an upright position. The vaporizer sump can be filled
when the vaporizer is in its WARM-UP cycle, or at any time the vaporizer is in use. If the vaporizer is in its
OPERATIONAL condition, the time taken for the agent to flow into the vaporizer may be increased. Only
agent bottles with a "Saf-T-Fill"™bottle probe specific to Suprane™(desflurane) should be inserted into the
filler port.
5.4.2 Filling Procedure
1. Remove the bottle cap from the Suprane™(desflurane) bottle and ensure that the 'O' ring is correctly
fitted to the bottle probe.
2. Insert the bottle probe into the filler port as illustrated in Fig. 16 and then push the bottle firmly against
the spring pressure until it is fully engaged with the filler port.
