USER RESPONSIBILITY
The SOMNI C3 is a precision medical vaporiser designed for Veterinary
Use Only. This vaporiser was designed to mix the vapours of specied
liquid anaesthetic gas agents with anaesthetic delivery gases. The
vaporiser will continue to provide reliable performance only if the
manufacturer’s operating and maintenance instructions are followed.
The vaporiser, as with any mechanical medical device, requires periodic
preventative maintenance and calibration. Any components, which
become worn, distorted, or contaminated should be replaced by a
factory authorised service centre. A vaporiser that requires service
should not be used until it has been accurately tested and veried by a
factory authorised service centre. Field-testing of vaporiser output using
portable test equipment, while valuable, is not a substitute for factory
authorised preventative maintenance. Factory service and calibration is
recommended every two years, eld-testing is recommended annually at
minimum. The user assumes full responsibility and liability of any use of
the vaporiser.

WARNINGS AND CAUTIONS
• This vaporiser is intended for Veterinary Use Only
• Do not ll the vaporiser with any agent other than the one specied on the front
label. Vaporisers are specically designed dependent on agent type. Therefore, any
other agent used can prove to be dangerous to a patient.
• Do not use this vaporiser until it is mounted upright, vertical and out of operation
for a minimum of (1) hour aer initial lling to allow for proper initial wick
absorption. Failure to allow wicking absorption time may result with inaccurate
output at the selected dial setting.
• Do not carry vaporiser by control dial. Handle and transport vaporiser with care
by grasping the vaporiser rmly with two hands.
• Do not modify, tamper, or disassemble the vaporiser. There is a probable
danger of damaging the vaporiser and altering the calibration accuracy.
• Do not put vaporiser into any liquid, including water.
• Do not attempt to sterilise vaporiser.
• Do not drain anaesthetic agent into any container other than a properly
marked container.
• Do not tilt or tip vaporiser beyond a 45-degree angle while lled with liquid
agent. If unit is accidentally tipped on its side, please call the manufacturer
for specic instructions.
• Do not have vaporiser serviced by anyone other than a SOMNI authorised
service centre.
• Do not operate vaporiser prior to leak testing the anaesthetic equipment,
ensuring secure connections to prevent unnecessary anaesthetic exposure
• Turn the vaporiser OFF when not in use.
• It is recommended that the vaporiser is kept upright at all times aer installation.

PRINCIPLES OF OPERATION
VAPORISER SUMP AND VALVE ASSEMBLY
This anaesthetic vaporiser is comprised of a vaporising chamber and duct
system (located within the sump cover), rotary valve and concentration dial. The
concentration dial is connected to the rotary valve underneath. The rotary valve
contains ducts and a vapour control channel. With the concentration dial in the
o position, the rotary valve links the inlet and outlet of the vaporiser, allowing
carrier gas to pass through. When the concentration dial is turned on, the carrier
gas is split in two: one stream owing into the bypass and the other owing into
the vaporising chamber.
The vapourising chamber contains two concentric wicks that are in contact
with the liquid anaesthetic agent. The wicks ensure the vapour is maintained at
saturation of concentration in the gas that leaves the vaporising chamber. The
ow through the vaporising chamber is controlled by the concentration dial.
Temperature compensation occurs automatically utilising a bi-metallic
strip to keep the output of the vaporiser constant during conditions of
changing temperature.

EXAMINATION AND PREPARATION FOR USE
1. Examine shipping carton for signs of external damage.
2. Remove contents from carton and inspect for visible damage
such as dents or missing parts.
3. If damage or missing parts are discovered or suspected, notify
customer service immediately at 0800 0129101.
4. Check that control dial operates freely.
5. Conrm the drain valve is completely closed .
6. Remove the mounting hardware (vaporiser spacer and 3-6mm bolts with
washers) and drain tube (*not shown) from package.
7
INSTALLATION
The standard mounting system requires bolting of the vaporiser directly
to a rigid back bar of an anaesthetic gas machine. The vaporiser should
always be mounted between the gas ow-metering unit and the
breathing circuit-always upstream of any absorber or humidier.
Ensure that emergency oxygen supplies or oxygen ush enter the
gas circuits downstream of the vaporiser.
The SOMNI C3 is supplied with mounting hardware consisting
of a spacer and 3-6mm bolts. While supporting the weight of
the vaporiser, install the spacer between the vaporiser and the
mounting surface and secure the vaporiser using the mounting
bolts provided. Ensure the bolts are tightly secured, but be sure
not to over-tighten.
Connect the 23mm inlet and outlet adapters to the corresponding
outlets on the cagemount. Twist and rmly push on for a secure,
leak-free connection. It may be necessary to connect the 23mm
adapters prior to mounting the vaporiser.
Complete a 10 second pressure test to conrm a leak free
installation. Instructions on Page 10.
8
INSTALLATION
• The direction of gas ow must be from “inlet to outlet”
(i.e. from le to right) when viewing the vaporiser from
the front.
• Ensure the liquid (which may accumulate in the
breathing circuit or the CO2 absorber) can not enter
the vaporiser while:
The vaporiser is tted with standard 23mm inlet and
outlet taper connections.
IMPORTANT! Vaporiser Spacer Placement
-in use
-during disassembly of the circuit
-when the machine is not in use

OPERATING INSTRUCTIONS
1. Observe all instructions and warnings on the vaporiser.
2. Fill only with agent indicated with vaporiser in OFF position.
3. Perform a leak test prior to rst use (See instructions
below- “10 Second Test”).
4. Depress locking button to turn dial from OFF position.
5. Turn dial counterclockwise to desired concentration.
6. Then turn control dial counter clockwise to desired concentration.
7. Turn vaporiser to “OFF” position when not in use.
10
10 SECOND PRESSURE TEST
Before each use, “leak test” the anaesthesia system and ensure the waste gases have a
patent way through the evacuation system.

Wear safety goggles or safety glasses.
Please Follow this protocol for refilling vaporiser
Turn O2 supply primary switch to “OFF”.
With vaporiser in “ON” position (2% concentration), drain oxygen from
line by turning “ON” fresh gas switch to induction chamber (be sure to
have evac for the induction chamber “ON”.
When oxygen stops flowing (flow meter will drop to zero and O2
pressure gauge will drop to zero), turn induction chamber fresh gas
supply to the “OFF” position.
Fill vaporiser with liquid anaesthetic.
Turn vaporiser dial to “OFF” position.
Turn O2 supply primary switch to the “ON” position.
