Setup and connections Setup and connections
Setup safety WARNING •
The vaporizer is designed for use with a General Electric Selectatec™ manifold. Do not use the vaporizer with other manufacturer’s anesthesia systems or in conjunction with other manufacturer’s vaporizers. Using the vaporizer with other systems may cause leaks, degradation of the interlock mechanism performance, and can add to the potential to mix two agents at the same time.
•
Only operate the vaporizer with dry medical gases. Vaporizer performance may be affected.
•
Do not modify, tamper with, or disassemble the vaporizer. Doing so can damage the unit and alter the accuracy of the control dial.
•
Earlier versions of Selectatec series mounted manifolds that provide mounting positions for three vaporizers require that if only two vaporizers are fitted, then the center position must be occupied. If the center position is not occupied, the interlock that helps ensure that only one vaporizer at a time can be turned on is ineffective.
Elements of the vaporizer Be familiar with the elements of the vaporizer before reading instructions in the subsequent sections of this manual.

Check that the vaporizer is in line with the manifold. If multiple vaporizers are mounted, check that the tops of the vaporizers are level. If the top of the vaporizer is not level, it is not correctly mounted. Attempt to lift the vaporizer off the manifold. If the vaporizer disengages from the manifold, it is not correctly mounted. Verify that the interlock mechanism works correctly by attempting to set the control dial of two vaporizers at the same time. If two vaporizers can be turned on at the same time, discontinue the use of the product and contact an authorized service representative. Check the anesthesia system for leaks in accordance with the section "Preoperative checkout".
Removing the vaporizer from a manifold 1. Make sure the control dial is set to the off position. 2. Unlock the locking lever. • Turn the locking lever counter-clockwise. • Release the locking lever and check that the locking lever springs up to the unlocked position to release the vaporizer from the manifold. 3. Carefully lift the vaporizer up from the manifold.

Operation Operation
Operation safety WARNING •
Do not use the vaporizer unless it has been properly installed per the Installation Instructions and has passed all relevant anesthesia machine checkout steps. Patient injury may occur or the user may be exposed to anesthetic agent by a leak.
•
The vaporizer should not be used when the control dial is between the off position and the first graduation mark. Output concentration of the vaporizer in this region is not defined.
•
Before using the vaporizer, allow it to attain the ambient temperature of the location in which it will be used. Failure to do so could affect the accuracy of the vaporizer.
•
European, international, and national standards require that anesthetic agent and oxygen monitoring is used when the vaporizer is in use. Refer to local standards for mandatory monitoring. If the anesthesia machine does not have integral gas monitoring, use of a standalone gas monitor is highly recommended or patient injury may occur.
•
Do not use the vaporizer if the liquid level decreases below the minimum level line, patient injury may occur.
Operating the vaporizer Make sure that the liquid level in the vaporizer is above the minimum line before using by observing the agent level indicator. 1. 2. 3.

Press the dial release button. Turn the control dial counter-clockwise to the desired concentration setting. Turn the control dial to adjust the concentration setting as needed. Turn the control dial clockwise to the off position when delivery of agent is complete.
2095452-001
Filling the vaporizer WARNING •
Do not fill the vaporizer with any agent other than the agent specified in product labeling. The vaporizer is designed for that agent only. Do not use the vaporizer with flammable anesthetic agents. If any substance other than that specified is used, patient injury could occur from wrong delivery, or user and patient may be exposed to an explosion hazard.
•
Do not put water or any other solvent into a vaporizer. Vaporizer parts may be damaged and output accuracy and composition of the output gas may be affected.
•
Do not attempt to fill the vaporizer beyond the maximum level line. Vaporizer performance may be affected.
Before filling the vaporizer, allow the vaporizer and anesthetic agent container to attain the ambient temperature. 1.

3. 4.
5.
6. 7.
Make sure the control dial is in the off position and vaporizer is in the upright position. Failure to do so may result in the vaporizer being overfilled. For bottles with an integrated adapter (such as Quik-Fil™, SAFE-TSEAL, and Piramal Fill), remove the integrated adapter cap. For bottles without an integrated adapter, remove the bottle cap and apply a bottle adapter following the adapter instructions. Remove the filler cap. Align the bottle adapter keys with the index slots on the filler port. Insert the agent bottle into the filling port. Press the agent bottle fully into the vaporizer filling port. Hold the bottle in the fully-inserted position. Allow the liquid to flow into the vaporizer until the maximum level mark or desired level on the agent level indicator is reached. To help prevent overfill, make sure the agent level is at or below the maximum level line. Release the bottle and remove the bottle from the filling port. Do not reinsert the bottle into the filling port if the vaporizer is already full. A small amount of anesthetic agent may leak to the environment during disconnection of the adapter from the filling port. Remove the bottle adapter (if applicable). Put the cap on the agent bottle or on the integrated adapter.

Preoperative checkout Preoperative checkout
Performing preoperative checkout Preoperative checkout is a series of tests to ensure an anesthesia system is in good operating condition and can be used in a clinical setting. The vaporizer is an important part of the checkout process because it is in circuit with the low pressure system of the anesthesia machine and could potentially contribute to gas leaks if not mounted or not functioning properly. Refer to the anesthesia machine User’s Reference Manual for recommendations on frequency of the checkout procedure. 1. 2.
Follow the instructions for the anesthesia machine checkout procedure. When the anesthesia machine tests for vaporizer leaks, run the test with the vaporizer in the off position and then rerun the test with the control dial set at 1% concentration. Additional control dial positions can optionally be checked.
If anesthesia machine checkout process is not available, see the "Comprehensive low pressure leak test" in "User maintenance" section to test the vaporizer for gas leaks. If vaporizer leak is found during the checkout, verify that the vaporizer is correctly mounted on the manifold, the cap is properly tightened and its sealing surface is intact, and run the checkout procedure again. If the checkout procedure fails, do not use the vaporizer and contact local authorized service representative.
