Introduction
Precautions w WARNING
Do not fill the vaporizer with any substance other than desflurane as specified on the front label. If any substance other than desflurane is used, patient injury could occur. U.S. Federal and Canadian law restrict this device to sale by or on the order of a licensed medical practitioner. Outside the U.S.A. and Canada, check local laws for any restrictions that may apply. Before using the Tec 6 Plus Vaporizer, you must be familiar with the desflurane package insert. Failure to conform to the recommendations on the insert can result in patient injury. Do not attempt to use a vaporizer that has been dropped. A dropped vaporizer MUST be sent to the nearest DatexOhmeda Field Operations Unit for servicing. See Section 10 for complete shipping instructions. Do not use malfunctioning equipment. Make all necessary repairs or have the equipment serviced by an authorized Datex-Ohmeda service center. After repair, test the equipment to ensure that it is functioning properly, in accordance with the manufacturer’s published specifications. Do not operate the vaporizer at an angle greater than 10° with respect to gravity. Improper agent delivery may occur.
Important:
European Standard EN 740 - Anesthetic Workstations and Their Modules requires that an appropriate gas monitor is used to monitor the concentration of anesthetic agent vapor in the inspiratory gas when the vaporizer is in operation in order to provide protection against hazardous output in the event of a device malfunction. Datex-Ohmeda strongly recommends the use of anesthesia gas monitoring with this equipment. Refer to local standards for mandatory monitoring.

Tec 6 Plus Vaporizer
What is a Tec 6 Plus Vaporizer? The Tec 6 Plus Vaporizer adds desflurane inhalant anesthetic vapor to the medical gasses supplied to a patient. The Datex-Ohmeda vaporizer should be used in anesthesia systems equipped with a Selectatec® Series Manifold only. The North American Dräger vaporizer should be used in anesthesia systems equipped with an exclusion manifold. Both variants of the Tec 6 Plus Vaporizer must be supplied with dry medical gas and be connected to a suitable AC power supply. The Tec 6 Plus Vaporizer is designed to meet UL 2601-1, EN 606011 and IEC 601-2-13.

Description
Mechanical and electrical interlocks incorporated into the vaporizer help to ensure that:
Important:
•
The vaporizer dial can only be turned from n (Standby) when the vaporizer is locked onto the manifold and the green OPERATIONAL light is illuminated to indicate that the vaporizer has attained the correct operating temperature.
•
Only one vaporizer can be operated at a time.
•
The gas flow only enters the selected vaporizer.
•
Unwanted anesthetic trace vapor is minimized after the vaporizer is turned to n (Standby).
European Standard EN 740 - Anesthetic Workstations and Their Modules requires that an appropriate gas monitor is used to monitor the concentration of anesthetic agent vapor in the inspiratory gas when the vaporizer is in operation in order to provide protection against hazardous output in the event of a device malfunction. Datex-Ohmeda strongly recommends the use of anesthesia gas monitoring with this equipment. Refer to local standards for mandatory monitoring.

w WARNING
This manual and its associated documentation must be studied before any attempt is made to install, operate or clean any part of the Tec 6 Plus Vaporizer. The performance of the anesthesia machine and vaporizer can be degraded if the machine and vaporizer are mismatched. To avoid explosive hazards, flammable anesthetic agents such as Ether and Cyclopropane must not be used in this vaporizer. Only anesthetic agents which comply with the requirements for non-flammable anesthetic agents in the IEC 601-2-13 Standard, particular requirements for the safety of anesthesia machines, are suitable for use in the presence of this vaporizer. As this vaporizer is not suitable for use with flammable anesthetic agents such as Ether or Cyclopropane, the use of antistatic breathing tubes and face masks is not necessary. The use of antistatic or electrically conductive breathing tubes when utilizing high frequency electric surgery equipment may cause burns and is therefore not recommended in any application of this vaporizer. The functioning of this vaporizer can be adversely effected by the operation of equipment such as high frequency surgical apparatus or short-wave therapy equipment in the vicinity. Do not operate the vaporizer other than with dry medical gases. The Tec 6 Plus Vaporizer must not be used in a Magnetic Resonance Imaging environment. The functioning of this Tec 6 Plus Vaporizer can be adversely affected by electromagnetic interference exceeding the levels specified in EN 60601-1-2. Do not attempt to use a vaporizer that has been dropped. A dropped vaporizer MUST be sent to the nearest DatexOhmeda Field Operations Unit for servicing. See Section 10 for complete shipping instructions.

Description
w CAUTION
If the vaporizer is not likely to be used for a period of 12 months, remove the battery. Failure to do so can result in damage to the vaporizer. The battery must be placed back into the vaporizer before use. A 'No Output' alarm could be caused by downstream high frequency ventilation at greater than 60 breaths/min with an airway pressure of 100cm H2O or pulsing the O2 flush faster than 1 pulse/sec over a time period of greater than 10 seconds.

Components Power supply unit
The Tec 6 Plus Vaporizer operates from a 100 to 120VAC 50/60 Hz or 220 to 240V AC 50/60 Hz electrical supply. A label on the rear panel of the vaporizer states the voltage requirement for the vaporizer. The integral power supply unit consists of a transformer and an AC to DC converter that provides the 12VDC and 5VDC supplies for the electrical system.
Filler assembly
The filler assembly uses an agent specific fitting to ensure that only a desflurane specific bottle equipped with a valve can be inserted to fill the vaporizer.

Description
Drain plug
The drain plug is located at the base of the vaporizer (see Figure 2-3).
w CAUTION
Do not remove the drain plug. Draining the vaporizer can result in rapid loss of pressure and/or agent, which could lead to injury to the operator. It must only be removed at a Datex-Ohmeda Authorized Service Center.
DRAIN PLUG

Power cord and battery
If the AC power supply fails, a Duracell MN1604 or VARTA Energy 2000 battery incorporated in the base of the vaporizer provides power for the auditory and visual alarms only. The battery must be replaced annually.

Equi-potential stud
The equi-potential stud Y is located on the top of the vaporizer. When connected, it minimizes any electrical potential difference between the vaporizer casing and the anesthesia system.
EQUI-POTENTIAL STUD
Figure 2-5 • Equi-potential stud
Sump
The sump contains 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.
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 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. While it is connected to the electrical supply, the casing of the vaporizer is normally warm to the touch.
Sensors
Internal electro/mechanical sensors monitor and maintain the fresh gas/agent vapor pressure balance and the agent volume. The internal sensors monitor and display operational status and activate the appropriate alarm indication.

Description
Agent level sensor
1107-0641-000
An agent level sensing probe measures the agent level. The power must be on for the agent level sensor to activate. If the sump contains between 60 and 390 ml of agent, the LCD level displays the agent level in the sump. For more information, see section 3, Controls and Indicators.
