Fisherbrand ovens have been designed for installation and operation in the following fields of
application:
 heat treatment;
 dr ing of material.
Fisherbrand ovens are for professional use onl .
Incorrect Use
To avoid the risk of explosion do not load the oven with tissue, material, or liquids that:
 are easil flammable or explosive;
 release vapor or dust that forms combustible or explosive mixtures when exposed to air;
 release poisons;
 create a humid atmosphere;
 release dust;
 exhibit exothermic reactions;
 are p rotechnical substances;
 exceed the specified hurdle load.
Standards and Directives
The oven complies with the following standards and guidelines:
 IEC EN 61010 - 1, IEC EN 61010 - 2 - 010
 Low Voltage Directive 2014/35/EC
 EMC Directive 2014/30/EC
 China EEP Hazardous Substances Information
http://www.thermofisher.com/us/en/home/technical-resources/rohs-certificates.html
Additionall , the oven is in compliance with man other international standards, regulations and
directives not listed here. Should ou have an questions regarding compliance with national
standards, regulations and directives applicable for our countr , please contact our Fisher
Scientific sales organization.

Acceptance Inspection
After the oven has been delivered, check the deliver immediatel for:
 completeness,
 possible damage.
If components are missing or damage is found on the oven or the packaging, in particular damage
caused b humidit and/or water, please notif the carrier as well as Technical Support immediatel .
Risk of injury
Should sharp edges have formed in damaged areas or elsewhere on the device, take
all necessary precautions to protect personnel handling the oven. For example, have
them wear protective gloves and other personal protection equipment.

Installation
Ambient Conditions
Location Requirements
Built-in units of incubators can, heating and dr ing ovens must be operated with an air exhaust
s stem and exhaust hose (onl original Fisher Scientific accessor should be used).
For safet reasons, the installation space should be made of non-combustible materials,
according to DIN 4102.
Use wit Air Ex aust Systems
For built-in units, a temperature-resistant and corrosion-proof exhaust hose should be used,
which can be connected to the air exhaust port with a draft interrupter.
If several built-in units in a row are connected to a central air exhaust s stem (see illustration), a
draft interrupter should be installed.
When the oven is connected to an air exhaust s stem be sure to adjust its air flow so the
temperature distribution pattern throughout the oven's workspace remains unchanged and
precision temperature control is maintained.
Also, be sure to interlock the oven and its exhaust s stem so both start and run at the same time.
The oven ma be unable to overcome the extra flow resistance introduced b the idle air exhaust
s stem, which ma cause the exhaust air to be vented into the surrounding lab room.
Before using existing piping in the building to exhaust hot air from the oven, be sure that such
exhaust piping is made of heat-resistant material, so it will not overheat, melt and/or cause a fire.
The oven’s outer surfaces and its air exhaust piping ma become hot, so be sure to maintain the proper
spacing from walls and ceilings specified b local building codes and/or fire protection regulations.
NOTE
During installation of built-in units, ensure that the escaping air will be safely discharged
out of the installation space.

Chapter 3
Mark hot exhaust air piping with appropriate hot surface warning signs or restrict access to such
piping altogether to avoid the risk of injur through contact with hot surfaces.
The oven must onl be operated in a location that meets all of the ambient condition requirements
listed below:
 Draft-free and dr indoor location.
 The dust burden ma not exceed the contamination categor 2 based on EN 61010-1. Using
the oven in an atmosphere with electricall conductive dust is prohibited.
 The minimal distance to adjacent surfaces must be observed on all sides.
 The operating room must be equipped with appropriate ventilation.
 Solid, level, fire-proof surface and no flammable materials opposite to the rear panel of the
oven.
 Vibration-proof substructure (floor stand, lab table) capable of bearing the dead weight of the
oven and its accessories (particularl if two devices are stacked).
 The ovens have been designed for an operating height of up to 2000 m above sea level.
 Ambient temperature range from 18 °C to 32 °C / 64.4 °F to 89.6 °F.
 Relative humidit up to 80% (maximum; preferabl 60-70%), non condensing.
 Should condensation exist, wait until the moisture has evaporated completel before
connecting the oven to a power source and powering up.
 If a high-voltage test is to be performed on the unit, it must first be heated for around
30 minutes at 75°C.
 Avoid direct exposure to sunlight.
 Devices that produce excessive amounts of heat must not be placed near the oven.
 To avoid dr ing operation without an appropriate fresh air suppl make sure that the air inlet
(which ma be equipped with an optional fresh air filter) is not obstructed or blocked b an
adjacent objects.
 Power line voltage variations must not exceed ±10 % of the nominal voltage.
 Transient overvoltages must not exceed the values usuall encountered throughout the power
suppl network. The nominal transient overvoltage level shall be the surge withstand voltage
according to overvoltage categor II of IEC 60364-4-443.

Installation | Chapter 3
 Place the oven on a floor stand (option; to be ordered separatel ), never on the lab floor.
 Consider installing one dedicated upstream circuit breaker per oven to avoid multiple device
failures in case of an electrical fault.
Intermediate Storage
When the oven is placed in intermediate storage, which is permissible for a maximum of four
weeks, make sure that the ambient temperature is between 20 °C to 60 °C (68 °F to 140 °F) and
the maximum relative humidit does not exceed 90%, non-condensing.
Room Ventilation
Heat dissipating from the oven during continuous operation ma cause a change in the room
climate.
 Therefore, the oven must onl be installed in rooms with sufficient ventilation.
 Do not install the oven in room recesses without ventilation.
 When several devices are to be placed in the same room, additional ventilation ma have to
be provided as necessar .
 To avoid an impact of the heat dissipated b the oven on the ambient climate the room must
be vented b means of a laborator -grade ventilation s stem that complies with applicable
local and national health and safet regulations and has sufficient capacit .
 If excessive temperatures tend to occur in the operating room, be sure to provide a thermal
protection means that cuts out the power suppl to mitigate the impact of overtemperature
scenarios.
