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 Requirement” 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 device 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.
• Relative humidity up to 80% (maximum; preferably 60-70%), non condensing.
• Condensation must be avoided - for example, after moving or transporting the device.
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 device.
• 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 with-
stand voltage according to overvoltage category II of IEC 60364-4-443.
• 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 humidity does not exceed 90%, non-condensing.
