THIS MANUAL MUST BE READ BEFORE SETTING UP AND OPERATING
THE SMARTBOX AUTO CO2SYSTEM. The user should be thoroughly familiar with
the contents of this manual prior to using the system with animals. Only technicians that
are properly certified should operate the system.
The user/owner of this equipment shall have the sole responsibility for any damage or
injury resulting from operation that is not in accordance with the authorized instructions.
This includes, but is not limited to, operating the equipment outside of recommended
safety levels, variation from specified operating instructions, and not following standard
laboratory safety procedures when working with anesthetic agents and volatile
compressed gases.
The system and its components must only be modified or repaired by Euthanex

Parts that have failed, in whole or in part, exhibit excessive wear, are contaminated or are
otherwise at the end of their useful life, should not be used and should be replaced with
parts supplied by Euthanex Corporation. Tampering with the main control unit by
unauthorized personnel automatically voids all warranties and specifications. The
manufacturer assumes no responsibility for any malfunction or failure of the unit if
tampering is suspected.
Overview:
The Lab Control Unit utilizes a programmable logic controller (PLC) that delivers a set
volume of CO2into an individual animal cage through the Euthanex Lid. The controller
unit operates at a fixed flow rate that is set at your external CO2source. Gas flows from
the external source into the Lab Control Unit. A solenoid valve opens to output gas to the
Euthanex Lid. After the euthanasia cycle is completed, the Lab Control Unit
automatically shuts the gas off.
The EA-31000 model treats a single cage or chamber.
The Lab Control Unit comes with one preset gas delivery timing. The EA-31000 offers a
single programmable timing. It is highly recommended that only designated, trained
personnel make adjustments to the timings, to ensure safe and effective settings.
Please refer to the “Flow Rate & Preset Times” section to derive the AVMA
recommended flow rate.

Flow Rate & Preset Times:
Default times were chosen to comply with the latest guidelines of the AVMA Panel
on Euthanasia and through extensive testing performed by Euthanex Corp. Times are
customizable to facility needs. The programmable times may be changed by a
designated administrator.
Preset Times: The units are pre-programed for Adult and Neonates unless
otherwise request at time of order.
Position 1 (Adult) = 5 minutes
Dwell = 5 minutes
Position 2 (Neonate) = 7 minutes
Dwell = 60 minutes
How to derive AVMA compliant flow rate from chamber size (for a single chamber):
Height(in) x Width(in) x Length(in)= Liters x 20% = flow rate
61
The 2013 AVMA Euthanasia Guidelines recommend 10 – 30% fill rate.
