D-TEC Desflurane Vaporizer Installation on

Machines with Removable Vaporizer Mounting Systems

Installation Procedure

NOTE: This procedure only applies to installation of D-Tec Desflurane vaporizer
on Narkomed 6000, Narkomed M, Narkomed GS Euro, Julian, Fabius GS and
Fabius machines with removable vaporizer mounting systems. Refer to Field
Service Procedure SP00091 for other desflurane vaporizer installations.

¡¡¡¡WARNING: Do not install a D-Tec vaporizer in the right hand position of a

Narkomed 6000 as this will result in an incorrect fit and may cause leaks in the
fresh gas delivery system.

¡¡¡¡WARNING: Do not install a D-Tec vaporizer on a Narkomed Mobile without the

correct vaporizer support block as this will result in an incorrect fit and may
cause leaks in the fresh gas delivery system. Refer to this procedure to verify
correct vaporizer support block prior to D-Tec vaporizer mounting.

¡¡¡¡WARNING: The O-rings supplied with this vaporizer are incompatible for use on

the Narkomed 6000, Narkomed GS Euro, Narkomed M, Fabius GS or the USA
manufactured Fabius. These systems shall only use O-RING #113 (NITRILE) P/N

4115864.

NOTE:Proceed to Section 2.0 if you are not

removing an existing vaporizer.

1.0 Vaporizer Draining, Drying and
Removal Procedure:

¡¡¡¡WARNING: Do Not install a D-Tec

vaporizer in the right hand position
of a Narkomed 6000 as this will result
in an incorrect fit and may cause
leaks in the fresh gas delivery
system.

Before removing an existing vaporizer
from the machine perform a fresh gas
leak test at the fresh gas outlet to verify
the initial gas circuit integrity. Refer to
the device service manual for specific
instructions.

¡¡¡¡Caution: The steps in this section

must be performed in the following
sequence:

1.1 Activate the waste gas scavenger.

1.2 Attach a breathing bag to the bag
mount port.

1.3 Open the APL valve to the minimum
position.

1.4 Connect the inspiratory and
expiratory valves using a 22 mm
hose.

1.5 Ensure the fresh gas hose is
connected between the absorber
system and the machine.

If there is an existing vaporizer in place,
it must be drained and dried as follows:

1.6 Turn the System Power switch to
ON.

1.7 Set the ventilation control to Manual
or MAN/Spont mode.

1.8 Set all vaporizer handwheels to their
“0” position.

¡¡¡¡WARNING: Do Not inhale anesthetic

vapors as this could result in
personal injury.

1.9 Open the filler and drain plugs and
drain the vaporizer into a suitable
container. Dispose of the residual
agent in an approved manner.

1.10 Close the filler and drain plugs.

1.11 Move the exclusion lever away from
the vaporizer being removed.
Depress the Zero release button and
rotate the vaporizer handwheel to
the maximum concentration setting.

1.12 Set the oxygen flow to 10 L/min. for
at least 20 minutes.

1.13 Turn the vaporizer handwheel to the
Zero position, set the oxygen flow to
minimum, and turn the System
Power switch to STANDBY.

1.14 Locate the vaporizer lock down lever
at the rear of the vaporizer, and turn
the lever 90° counter-clockwise.

NOTE: Earlier units are not configured as

“User Removable” and therefore
require a special wrench (P/N

4114522) to be inserted into the
keyed spline which is covered by a
“DO NOT REMOVE” label. Remove
this label for access to the keyed
spline through the rocker plate at the
rear of the vaporizer, and turn the
tool 90° counter-clockwise. See
Figure 1.

1.15 Verify that the exclusion slider bar is
disengaged from the vaporizer being
removed.

1.16 Hold the vaporizer with two hands
and lift it up until it clears the
mounting block, then bring it
forward to clear the machine.

2.0 Machine Preparation:

2.1 Before installing a vaporizer,
perform a fresh gas leak test at the
fresh gas outlet to verify gas circuit
integrity. Refer to the device service
manual for specific instructions.

2.2 Examine the vapor mount O-rings
and replace them if needed.

¡¡¡¡WARNING: The O-rings supplied with

this vaporizer are incompatible for
use on the Narkomed 6000,
Narkomed GS Euro, Narkomed M,
Fabius GS or the USA manufactured
Fabius. These systems shall use only
O-ring #113 (NITRILE) P/N 4115864.

Note: The following two steps apply to

the Narkomed Mobile and Fabius
machines.

2.3 Verify the correct vaporizer support
block is installed on the vaporizer
mount. See Figure 2.
