Installation
Ambient Conditions
Location Requirements
The refrigerated incubator must only be operated in a location that meets all of the ambient
condition requirements listed below:
• Installation location indoors in dry areas free from drafts.
• The dust burden may not exceed the contamination category 2 based on EN 61010-1.
Using the refrigerated incubator 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 3-3)
• The operating room must be equipped with appropriate ventilation.
• Solid, level, fire-proof surface; no flammable materials opposite to the rear panel of the
refrigerated incubator.
• Vibration-proof substructure (floor stand, lab table) capable of bearing the dead weight of
the refrigerated incubator and its accessories (particularly if two devices are stacked).
• The electrical circuitry of the refrigerated incubator has been designed for an operating
height of up to 2000 m above sea level.
• If a high-voltage test is to be performed on the unit, it must first be heated for around 30
minutes at 50°C.
• The ambient temperature must be within a range of +18 °C to +28 °C (64 °F to 82 °F).
• Avoid direct exposure to sunlight.
• Devices that produce excessive amounts of heat must not be placed near the refrigerated
incubator.
• Place the refrigerated incubator on a floor stand (option; to be ordered separately), never
on the lab floor. This prevents the penetration of dust or dirt into the device.
• Power line voltage variations must not exceed ±10 % of the nominal voltage.
• Transient surges must lie within the range of levels that normally occur in the power
supply system. The impulse withstand voltage based on surge category II of
IEC 60364-4-443 shall be applied at the nominal voltage level.

Installation
Intermediate Storage
3-2 Heratherm IMP Thermo Scientific
• Relative humidity up to 70%, non condensing, at an ambient temperature of 28°C.
• Should condensation exist, wait until the moisture has evaporated completely before
connecting the refrigerated incubator to a power source and powering up.
• Consider installing one dedicated upstream circuit breaker per refrigerated incubator to
avoid multiple device failures in case of an electrical fault.
Intermediate Storage
When the refrigerated incubator 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 refrigerated incubator during continuous operation may cause a
change in the room climate.
• Therefore, the refrigerated incubator must only be installed in rooms with sufficient
ventilation.
• Do not install the refrigerated incubator 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 refrigerated incubator 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
over-temperature scenarios.
Humidity
After transport or storing 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.
Contamination hazard
Do not place the refrigerated incubator directly on the lab floor,
but mount it on the floor stand or on a lab work surface (option;
to be ordered separately). Contaminants, such as bacteria,
viruses, fungi, prions, and other biological substances may use
the open door to migrate easily from the floor into the refrigerated
incubator’s work space.
