3-2 Peltier Low Temp. Incubators Fisher 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 low temperature incubator to a power source and powering up.
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 xx hours.
• Consider installing one dedicated upstream circuit breaker per low temperature incubator
to avoid multiple device failures in case of an electrical fault.
Contamination hazard
Do not place the low temperature 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
low temperature incubator’s work space.
Intermediate Storage
When the low temperature 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 low temperature incubator during continuous operation may cause
a change in the room climate.
• Therefore, the low temperature incubator must only be installed in rooms with sufficient
ventilation.
• Do not install the low temperature 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 low temperature 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.
