THIS MANUAL MUST BE READ BEFORE SETTING UP AND OPERATING THE SMARTBOX AUTO CO2 SYSTEM. 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 authorized service technicians. Improper modification or repair may result in danger to personnel, harm or death to animal, and/or equipment damage. The user/owner of this equipment shall have the sole responsibilit
y for any damage or injury resulting from improper maintenance and repair that is not done by authorized maintenance and repair personnel.
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 CO2 into an individual animal cage through the Euthanex Lid.  The controller unit operates at a fixed flow rate that is set at your external CO2 source.  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-34000 model treats 4 cages or chambers.
The Lab Control Unit comes with one preset gas delivery timing.  The EA-34000 offers 4 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.
The lightning flash with an arrowhead
symbol within an equilateral triangle, is intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons.
