Chapter 1
For any activity on the environmental chamber:
✔Always use the proper protective equipment (clothing, gloves, goggles, etc.)
✔Always dissipate extreme cold or heat and wear protective clothing.
✔Always follow good hygiene practices.
✔Each individual is responsible for his or her own safety.
Basic Operating Precautions
These operating instructions describe environmental chambers.
The environmental chambers have been manufactured to the latest state of the art and
have been tested thoroughly for flawless functioning prior to shipping. However, the
environmental chambers may present potential hazards, particularly if it is operated by
inadequately trained personnel or if it is not used in accordance with the intended
purpose.
Therefore, the following must be observed for the sake of accident prevention:
Never step into the unit.
The environmental chambers must be operated by adequately trained and authorized
professional personnel.
The environmental chambers must not be operated unless these operating
instructions have been fully read and understood.
For any operation of this device, the operator must prepare clear and concise written
instructions in the language of the operating and cleaning personnel based on these
operating instructions, applicable safety data sheets, plant hygiene guidelines, and
technical regulations, in particular:
The decontamination measures to be employed for the environmental chamber and
the accessories used with it.
The safety precautions to be taken when processing specific agents.
Wearing protective equipment when handling e.g. microbiological and biological
samples.
The measures to be taken in case of accidents.
Repair work on the environmental chamber must be carried out only by trained and
authorized expert personnel.
WEEE Compliance: Thermo Fisher Scientific has contracted with companies for
recycling/disposal in each EU Member State. For further information, send an email to
[e-mail].

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.
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.
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.
If the environmental chamber is not used in the manner specified in this
operating manual, the protection provided by the equipment design maybe
impaired.

Warranty
Thermo Fisher Scientific warrants the operational safety and functions of the
environmental chambers only under the condition that:
The environmental chamber is operated and serviced exclusively in accordance with
its intended purpose and as described in these operating instructions.
The environmental chamber is not modified.
Only original spare parts and accessories that have been approved by Forma are
used (third-party spares without Forma approval void the limited warranty).
Inspections and maintenance are performed at the specified intervals.
An operation verification test is performed after each repair activity.
Intended Use
Forma Environmental Chambers with light option are laboratory devices intended for
Stability testing,
Shelf life studies, packaging testing,
Light stability testing,
Cultivation of: cells, tissue, micro organism cultures for research only,
Plant growth,
Hatching of insects, fish or other animals and microorganisms that require light
exposure,
Refrigerated storage or long term storage of substances and samples.
The devices employ:
Precision temperature control - above or below and above ambient temperature,
depending on model
Precision humidity control: some models only
On option: Precision CO2control
On option: Light control for day/night simulation and light stability testing for
simulating the specific physiological ambient conditions for these cultures, organisms
and test or storage applications acc,. ICH guideline.
Unintended Use
The appliance is not explosion-proof. To avoid the risk of explosion do not load the
environmental chamber with tissue, material or liquids that:
are easily flammable or explosive,
