Operational Safety Rules - Thermo Scientific 3907 Operating Manual

Thermo Scientific
Disconnect the unit from all power sources before cleaning, troubleshooting, or

performing other maintenance on the product or its controls. To disconnect power
supply to the environmental chamber, unplug the supply cord at the back of the
chamber. Note that deactivating the main switch on the front control panel to the Off
position is not sufficient to disconnect power.
The contents of these operating instructions are subject to change at any time

without further notice.
Keep these operating instructions close to the environmental chamber so that safety

instructions and important information are always accessible.
Humidity
After transport and decommissioning, or storage under humid conditions a
drying-out process must be performed. During the drying-out process the
equipment cannot be assumed to meet all the safety requirements of the IEC
61010-2-010 standard. The drying-out period is 2 hours.
Should you encounter problems that are not detailed adequately in these operating

instructions, please contact Thermo Fisher Scientific immediately for your own.

Operational Safety Rules

The following rules must be heeded when working with environmental chambers:
Observe the sample weight limits specified for your environmental chambers, whole

and its shelving in particular; see "Specifications" on page 12-1.
Arrange the samples evenly throughout the work space, making sure not to place

them too closely to the interior walls to ensure a uniform temperature distribution.
Do not load your environmental chambers with substances that exceed the

capabilities of the available lab apparatus and personal protection equipment to
provide sufficient degrees of protection to users and third parties.
Check the door seal every 12 months for proper sealing performance and possible

damage.
Do not process any samples containing hazardous chemical substances that may be

released into the ambient air through defective seals or may cause corrosion or other
defects on parts of the environmental chamber.
The tempering of defined substances or materials with higher moisture content can

result in increased condensation in the chamber. Measures must be observed.
The user is responsible for carrying out appropriate decontamination procedures

when hazardous materials are spilled on or inside the environmental chamber.
If the environmental chamber is not used in the manner specified in this
operating manual, the protection provided by the equipment design maybe
impaired.
