INTENDED USE
The SOMNI AMD-3+ Accurate Multi-Delivery System is a pressurized flowmeter
controlled diverter system designed for Veterinary Use Only. The AMD-3+ gives
the user the ability to deliver accurate adjustable flow rates to three stations
simultaneously. Each station has a flowmeter to control the volume delivery
needed. For ease of use, each flowmeter also has a on/o toggle switch. Set
the flow rate needed on the flowmeter and utilize the switch when the flow
rate used is consistent. Use of a pressurized flow controlled anesthesia system
ensures continuous, consistent and accurate flowrates to each station for the
duration of the procedure. The SOMNI AMD-3+ system includes a SOMNI 3
6psi calibrated Isoflurane vaporizer. Only use the AMD-3+ system with a 6psi
specially calibrated vaporizer, failure to do so can result in equipment damage
and inconsistent flow rates/anesthetic concentration to the animal.

WARNINGS, NOTES AND DEFINITIONS
Warning! System is pressurized to approximately 6 psi when in use! Fail-
ure to follow Depressurization procedure will result in high levels of anes-
thetic exposure!
Warning! Operator must read entire manual prior to operation and be
trained in the use of inhalant anesthetic equipment. Failure to do so may
harm the animal.
Warning! Only use accessories appropriate for use with nonrebreathing
anesthesia systems. Failure to use appropriate accessories can result in
animal injury, poor anesthetic delivery and waste gas exposure.
Warning! Do not connect unregulated carrier gas to the anesthesia system.
Oxygen or another carrier gas should be supplied at 50 psi.
Warning! Only use a 6psi calibrated vaporizer with this system. Use of a
vaporizer that has not been calibrated at 6psi may harm the vaporizer and
result in inaccurate anesthetic flow rates and/or concentrations to the
animal.
Warning! Vaporizer is pressurized when in use. Do not attempt to open
the fill cap and replenish agent without following depressurization proce-
dure!
Warning! Always operate inhalant anesthetic equipment with waste gas
scavenging systems. Failure to control waste anesthetic gas may cause
harmful exposure to personnel.
Note! Only use non-rebreathing style circuits and accessories

• Connect the black tubing from the vaporizer inlet (6) to the
oxygen outlet (7) on the back of the AMD-3+.
• Connect the black tubing from the vaporizer outlet (8) to
the gas inlet (9) on the back of the AMD-3+.
• Connect the oxygen (carrier gas) supply hose to the DISS
male fitting (10) on the back of the machine. Turn the
carrier gas supply on at the source (cylinder regulator or
concentrator). Do not turn the AMD 3+ main oxygen supply
toggle switch on until ready to begin.

PRODUCT OPERATION
• Place the SOMNI AMD-3+ on a flat, stable surface and ensure the main oxygen
supply switch is in the “OFF” position.
• Connect the fresh gas delivery lines supplied to each of the common outlets
labelled A, B, or C. If one of the lines is not needed, it is not necessary to
disconnect it.
• Connect optional breathing accessory or induction chamber utilizing the color
coded fresh gas delivery lines.
• Connect appropriate active or passive waste gas scavenging system to each
accessory in use.
• Ensure vaporizer has been filled with anesthetic agent and allowed to wick for
a minimum of 1 hour, see vaporizer manual and filling protocol following this
section for further instructions.
• Turn the main oxygen supply toggle switch on/up. The pressure gauge should
read ~6psi.
• Toggle each flowmeter toggle switch up/on to allow flow to begin. Adjust
each flowmeter to the level of flow needed for each gas delivery line and
corresponding accessory. See suggested flow rates. Confirm oxygen flow
through each of the gas delivery lines.
• If all flowmeters will not be utilized, it is not necessary to turn the flowmeter o,
only toggle the toggle switch down/o to stop the flow.
• To begin, ensure the waste gas scavenging system is connected and turned on.
Place animal(s) into induction chamber and provide oxygen or other carrier gas
flow.
• Verify the chamber is closed and then turn on the vaporizer to the desired
anesthetic percentage.

• Follow established guidelines regarding flowrates
and percent anesthetic concentration. Suggested
fresh gas flow to any accessory (except hooded style
induction chamber) SHOULD NOT EXCEED 1 LPM.
Recommended maximum fresh gas flow rate for
induction chamber is 2 LPM.
Suggested Fresh Gas Flow Rates*
Uniflow/Miniflow/Equaflow Rat: < 1 LPM
Equaflow 3: < 3 LPM
Equaflow 5: < 5 LPM
Equaflow 10: < 10 LPM
• At procedure completion, turn the anesthetic
vaporizer o and allow the anesthetic gas to be
removed by the scavenging system.
• Turn the oxygen (carrier gas) supply o at the source
(cylinder regulator or concentrator) and allow the
pressure gauge on the AMD-3+ to fall to 0.
• Next turn o each of the station flowmeter toggle
switches. Turn the main oxygen supply toggle switch
o and lastly turn o the scavenging system.

Wear safety goggles or safety glasses.
Please Follow this protocol for refilling vaporizer
Turn O2 supply primary switch to “OFF”
With vaporizer 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 vaporizer with liquid anesthetic.
Turn vaporizer dial to “OFF” position.
Turn O2 supply primary switch to the “ON” position

ROUTINE MAINTENANCE TROUBLESHOOTING
Flowmeter will not turn o – Needle valve may be
worn
Animals will not go to sleep/stay asleep – Inspect
system for leak
• tighten any loose connections (vaporizer endcaps,
tubing connections)
• verify flowmeter toggle switch is on, flowmeter is
turned on
• confirm oxygen (carrier gas) supply is adequate and
on
• confirm liquid anesthetic level in vaporizer is
adequate
• inspect breathing circuit/nosecone and/or induction
chamber for leak or loose connection
• check active waste gas system function/attenuation
Call 877-637-3625 for assistance
Daily test: Oxygen Flow:
• Turn the oxygen supply source on.
• Turn the main oxygen supply toggle switch on.
• Turn each flowmeter knob fully open and observe
the float ascends and descends freely and rests
completely at the bottom when knob is turned o.
• Open and close each toggle switch, checking for gas
flow through delivery lines when open and verify loss
of flow when closed.
Daily test : Internal leak check:
• Turn the oxygen supply source on.
• Turn the main oxygen supply toggle switch on (AMD-
3+).
• Turn each flowmeter toggle switch on.
• Ensure scavenging system is turned on/connected.
• Turn Vaporizer on.
• Turn the oxygen supply source o.
• Turn flowmeter toggle switch o.
• Turn main oxygen supply toggle switch o (AMD-3+)
• Observe pressure gauge. If system pressure drops
contact Somni Support.
• Inspect lines, connectors and accessories for wear
prior to use.
Cleaning
• Use a damp cloth to clean, do not spray cleaning
agent directly onto the AMD-3+. Dilute Chlorhexidine
or similar cleaning and disinfecting agent can be
used. Do not use alcohol.
