Preface
Important Read this instruction manual. Failure to read, understand and follow the instructions in this manual
may result in damage to the unit, injury to operating personnel, and poor equipment performance. s
Caution All internal adjustments and maintenance must be performed by qualified service personnel. s
Warning If the incubator is not used in the manner specified in this operating manual, the protection provided
by the equipment design may be impaired. s
Caution When operating this unit under high temperatures and/or relative humidity (RH), caution must be
observed when the unit is shut down, unexpectedly or by choice. Condensate can form on the interior of the
chamber as it cools. This includes the heating element surfaces. Heavy condensate can bridge the ceramic
insulators and cause a temporary electrical short to ground. This electrical circuit is protected by a circuit
breaker. However, to avoid this contingency if these conditions occur, open the door of the unit and allow it
to stand open until the water vapor disperses. s
The CO2 incubator described in this manual is a high performance unit that can be used for research and to
support medical applications. More specifically, this product is intended for:
• Use as a general purpose microbiological CO2 incubator
• Medical purposes to cultivate microorganisms and diagnostic use (storage of samples not intended to be
re-introduced to the human body).
When used for these medical purposes, this CO2 incubator is regulated as a Class I medical device by the U.S.
Food and Drug Administration (“FDA”).
Material in this manual is for information purposes only. The contents and the product it describes are subject
to change without notice. Cardinal Health makes no representations or warranties with respect to this
manual. In no event shall Cardinal Health be held liable for any damages, direct or incidental, arising out of or
