Installation
Ambient Conditions
Location Requirements
Built-in units of incubators can, heating and drying ovens must be operated with an air
exhaust system and exhaust hose (only original Thermo accessory should be used).
For safety reasons, the installation space should be made of non-combustible materials,
according to DIN 4102.
Use with Air Exhaust Systems
For built-in units, a temperature-resistant and corrosion-proof exhaust hose (only original
Thermo accessory) 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 system (see illustration),
a draft interrupter should be installed.
During installation of built-in units, ensure that the
escaping air will be safely discharged out of the
installation space.
Fig. 1 Fig. 2

Installation
Ambient Conditions
3-2 Heratherm Thermo Scientific
The oven must only be operated in a location that meets all of the ambient condition
requirements listed below:
• Draft-free and dry indoor location.
• The dust burden may not exceed the contamination category 2 based on EN 61010-1.
Using the oven in an atmosphere with electrically conductive dust is prohibited.
• The minimal distance to adjacent surfaces must be observed on all sides (see section
“Space equirement” on page 3-4).
• 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 (particularly 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.
• elative humidity up to 80% (maximum; preferably 60-70%), non condensing.
• Should condensation exist, wait until the moisture has evaporated completely before
connecting the oven to a power source and powering up.
• Avoid direct exposure to sunlight.
• Devices that produce excessive amounts of heat must not be placed near the oven.
• To avoid drying operation without an appropriate fresh air supply make sure that the air
inlet (which may be equipped with an optional fresh air filter) is not obstructed or
blocked by any adjacent objects.
• Power line voltage variations must not exceed ±10 % of the nominal voltage.
• Transient overvoltages must not exceed the values usually encountered throughout the
power supply network. The nominal transient overvoltage level shall be the surge
withstand voltage according to overvoltage category II of IEC 60364-4-443.
• Place the oven on a floor stand (option; to be ordered separately), 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.

Installation
Intermediate Storage
Thermo Scientific Heratherm 3-3
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 humidity does not exceed 90%, non-condensing.
Room Ventilation
Heat dissipating from the oven during continuous operation may cause a change in the room
climate.
• Therefore, the oven must only 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 may have to
be provided as necessary.
• To avoid any impact of the heat dissipated by the oven on the ambient climate the room
must be vented by means of a laboratory-grade ventilation system that complies with
applicable local and national health and safety regulations and has sufficient capacity.
• If excessive temperatures tend to occur in the operating room, be sure to provide a thermal
protection means that cuts out the power supply to mitigate the impact of
overtemperature scenarios.
Use with Air Exhaust Systems
When the oven is connected to an air exhaust system 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 system so both start and run at the same time.
The oven may be unable to overcome the extra flow resistance introduced by the idle air exhaust
system, which may 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 may become hot, so be sure to maintain the
proper spacing from walls and ceilings specified by local building codes and/or fire protection
regulations.
• Mark hot exhaust air piping with appropriate hot surface warning signs or restrict access to
such piping altogether to avoid the risk of injury through contact with hot surfaces.
