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

Material in this manual is for information purposes only. The contents and the product it describes are subject to

change without notice. Thermo Fisher Scientific makes no representations or warranties with respect to this

manual. In no event shall Thermo be held liable for any damages, direct or incidental, arising out of or related to

the use of this manual.
