Section 1 Cautions and Warnings
Caution Read these notices before installing the unit. s
As a routine laboratory precaution, always wear safety glasses when
working with this apparatus.
Allow the incubator to cool to approximately 100°F (38°C) before
changing from HEAT to COOL switch positions.
The uniformity will be adversely affected if air circulation is obstructed.
DO NOT place any explosive, combustible, or flammable materials in the
chamber.
DO NOT place sealed containers in the chamber. Sealed containers, filled
with materials, do not provide room for expansion and can develop
dangerous vapor pressure as the temperature increases.
Avoid spillage of large volumes of liquids.
DO NOT evaporate noxious fumes.
The liquid level in the container should be checked daily to prevent
overflow.
Allow a 4°C differential between the desired operating temperature and the
safety temperature.
