5-2 30 cu ft Incubators Thermo Scientific
Section 5
Explanation of Controls
All Models (continued):
LINE Pilot Light - This light will glow after electrical power is connected
to the terminal strip per the installation instructions and attached wiring
diagram.
Interior Light Switch - This is located on the right-hand side of the
chamber and is actuated by opening or closing the door. When the door is
open, the light inside the chamber will glow; and when the door is closed,
the light is out.
Standard Temperature Model Only:
Heat "On-Off" Switch - This switch controls electrical power to the
heater, relay, and blower motor. It does not de-energize the internal
chamber light or the convenience outlet electrical circuits.
Low Temperature Model Only:
COOL-HEAT Switch - A three-position (Cool-Heat-Off) switch is
supplied. This switch allows the operator to change the chamber
temperature to meet the given application. The recommended switch
positions for a given temperature range are as follows:
Switch Position Temperature Range
COOL 5°C to ambient plus 10°C
HEAT Ambient plus 10°C to 70°C
"OFF" None - no electrical power to heater or compressor
When the COOL pilot light glows, the compressor is actuated; and
when the CONTROL pilot light glows, the heaters are energized.
Compressor Cutoff Switch - A thermal switch is provided above the
ceiling panels and in the rear of the control compartment. This switch
(normally closed) will open on temperature rise, approximately 125°F
(52°C), and it will prevent damage to the compressor due to excessive
pressures created by high temperature in the chamber.
NOTE Allow the incubator to cool to approximately 100°F (38°C) before
changing from HEAT to COOL switch positions.
