Intermediate Storage; Room Ventilation - Thermo Scientific Heratherm IMH 60 Operating Instructions Manual

Installation

Intermediate Storage

• Devices that produce excessive amounts of heat must not be placed near the incubator.
• Place the 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.
• Consider installing one dedicated upstream circuit breaker per incubator to avoid multiple
device failures in case of an electrical fault.
Intermediate Storage
When the 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 incubator during continuous operation may cause a change in the
room climate.
• Therefore, the incubator must only be installed in rooms with sufficient ventilation.
• Do not install the 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 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
overtemperature scenarios.
3-2 Heratherm
Do not place the 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 incubator's work space.
