4.1 Utilities requirements
The following utilities requirements are needed for operation:
4.2 Selecting the location
Select a level surface capable of withstanding the operating weight of the incubator. Actual operating
weight will be dependent on both the options installed, and the material stored in the incubator.
The incubator is designed to operate at a chamber temperature of 4.0 °C above ambient, and at an absolute
minimum ambient temperature of 15 °C if the incubator is being operated at 37 °C.
Maximum allowable
ambient temperature is 28 °C.
Avoid placing the incubator in areas that may affect performance, such as those listed below.
DO NOT place the incubator:
• Directly under, beside or within the air flow of heating or air-conditioning ducts, or other drafts;
• Directly beside heat-generating equipment such as a heater, an autoclave or an oven;
• Near the exhaust of heat- or cold-generating equipment;
• Near a window exposed to direct sunlight;
• Directly on top of any heat-generating apparatus;
• Without minimum ventilation clearance of 10 mm (0.5 in) all around (50 mm (2 in) in back if you have
the cooling system option).
Utility Requirement
Electricity 120 V, 50/60 Hz earthed/grounded mains/electrical supply with minimum
capacity of 10 amps
230 V, 50/60 Hz earthed/grounded mains/electrical supply with minimum
capacity of 8 amps

gas pressure must not exceed 5 PSI (0.35 bar). It is recommended that a in-line pressure
regulator be used for each gas type introduced into the incubator to precisely control gas
pressure (see
Accessories on p. 63).
